Read complaints for GMC SIERRA 2500 HD (2004)


My truck is a work truck driven by an employee, i have just recently become aware of a condition regarding the instrument cluster, wherein the whole panel does not work, i was advised by the employee that this happened quite some time ago, but was never made aware.i contacted gmc but apparently, because this is considered a special policy recall (only if someone complains - and within a specified time period 7 yrs or 80,000 miles) they will not repair this defect.i never received a notice, nor was i aware of the problem within that time period.i was further informed by my worker that at the time the panel went out, the fan for the heater/air condition unit appeared to smoke and now it does not work.here again, i have not received any recall notices for this defect either. Finally, in my attempts to get the cluster repaired, i have been informed that there is a recall on the hydro boost accumulator... I have not once received a recall notice on this vehicle and i purchased this vehicle new.my vehicle has 101,000 miles on it.you would think that a vehicle of this nature would last longer than 100,000.but apparently not... Also, when these is such a major recall out on a vehicle you would think that gmc would contact you and advise you of this problem..

The instrument panel cluster gauges don't always work. We were on freeway when we noticed speedometer had failed as well as fuel gauge , temp gauge all gauges inoperative. This is third time cluster panel is being replaced; first two under warranty third time we had to pay $204.

My vehicle had brake lines replace two times with less than 65,000 miles because breaks stop working. Fuel line replaced under 55,000 miles because it made check engine lightcome on speedometer erratic,oil pressure gauge high and low,fuel gauge erratic under 65,000 miles.loud noise from engine service technicianreported the exhaust manifold bolts has broken to call a white smoke from the motor.everything happened with consider to be low mileagein talking to gm they don't care because enough report has not been made.

Instrument display panel specifically the speedometer is now frozen at 120 mph. It happened at just under 60k miles on the vehicle. I had received notice that they would repair but now have to many miles on the vehicle. The cap on mileage is approximately 70k. Im happy to know that this part of the vehicle has nothing to do with safety. Gmc wanting some $500 - $600. Dollars to fix this is the real issue. The 2004 chevy i own as well did the exact same thing. No problem here is there?

2004 gmc sierra speedometer reading fluxuates intermittently, showing incorrect speed.this began to occur at 54,000 miles.

Parked my truck in the driveway tonight and shut it off.the mirrors went crazy, and the radio would not shut off.after a few minutes i started the truck and shut it back off.the radio went off.since owning the truck, which is not very long, i have had the power seats readjust themselves, by them selves, and it felt like it was crushing me.i am a big man and i prefer that no one adjust my seats, as i have them just right for me.this truck and its wiring/electrical system are problematic.so sorry i bought it now.

Received a conditional letter from gm stating that my vehicle my experience a condition resulting from corrosion that may effect the relay resistor module and wire connector for the heater/hvac fan motor. The letter states that the wire and/or resistor could overheat. This may be accompanied by a burning smell or smoke. I have first hand knowledge that a co-workers truck caught fire on july 26, 2011 do to this specific problem. Several people have complained via the internet about fire damage from this condition. I have talked to general motors about this issue and they failed to react. My co-worker did not have any symptoms prior to his vehicle catching fire under his dash that totaled his truck. I am concerned that my truck will catch fire without notice and as a result potentially burn down my house. Whenever someone describes a symptom as a burning smell or smoke it is potentially to late to fix the issue and could cause bodily harm or death.

The contact owns a 2004 gmc sierra 2500 hd.while driving 55 mph, the vehicle began smoking near the glove box.the plastic coating on the wires began dripping, melting, and sparking.the vehicle then became engulfed in flames and was destroyed.a police and fire report was filed.the contact has pictures.the mileages were unknown.

My ignition also switches off due to the key chain being to heavy, i would like my vehicle fixed as well. I think gm is not telling the whole story on how many vehicle are affected by the ignition switches. I can prove my claim by attaching my two key chains together again and the problem will occur again.

The contact owns a 2004 gmc sierra 2500 hd. The contact stated that while driving 50 mph, the speedometer failed to move. The vehicle was taken to the dealer for inspection where they stated that the instrument cluster needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 50,000.

Allison transmission housing failed at 54,000 miles. Gm paid parts, i paid 1,200.00 labor , was toldthat there was 2 bulletins out on defective housing and when they finished repair they said they installed updated housing so i would not have problem again. Don't think i should have paid anything to have it repaired! at 105,000 miles transfer case failed , cost 1,150.00to repair, have had to take back 2 more times as repair was not done right. At 112.000 miles speedometer becameerratic was told it was a common problem ,and see on complaint search it is , consider this a great safety danger as i do not know what speed i'm going can only guess not fixed yet found some who sells rebuilt ones foe 150.00 ,said their rebuilding them due the large number that are failing. Also at 112,000 miles park neutral switch started acting up ,check engine light on ,shift bar light goes away, truck won't shift properly and stay in certain gears without shifting up ,effects door locks. Looked up park neutral shift as part and came across bulletins stating that during left hand turn front tire sprays water onto park neutral ,switch causing problem ,needs front & rear shield installed to solve problem. Have taken truck back in waiting for information. Also around 90,000 miles had very hard time starting truck and truck ran poorly,problem became worse took in, fuel injectors were bad and were replaced under warranty at 112,000 miles no need to say i'm not a gmc fan anymore , even though i live in lansing mi ( a gm town)and have lots of friends and family employed there. Good by gmc! never again.

The speedometer does not always zero out after the vehicle comes to a stop and the oil pressure gauge goes to zero while driving.

Instrument cluster malfunction. To the best of my knowledge the only gauges working properly are the tachometer and fuel gauge. It began with intermittent speedometer malfunction. Took it in as warranty work but the service dept. Could not duplicate the issue. After the warranty expired the issue resurfaced. I asked about any recalls or complaints regarding the cluster gauges malfunctioning at every visit for service. No recalls or complaints received according to them. Did some research on the subject. Found a few similar complaints in blogs but no action from gm. The problem began to cascade and soon all gauges except for the tach and fuel began to fail. Not fix as of yet. Gm has a notice out on it but refuses to repair my truck due to having too many miles. They even found documentation at the dealership service dept. For the original speedometer malfunction but they state it wasn't a strong enough complaint.

2004 gmc 2500 hd.purchased my truck in fall of 2003.my speedometer stopped working properly.truck only has 45k miles.dealership advised the instrument cluster panel was bad needed to be replaced.new part is @ $210.00 plus labor.the seal on my right front axle is also starting to leak.

2004 gmc sierra slt duramax 2500hd.92,000 miles.well -maintained.with no warning speedometer read forty miles too low.we thought we were entering the freeway at 60, while in fact we were going 20.we almost got rammed by a truck.it is illegal to go 20 on an interstate.this required speedometer cluster replacement costing $529.gm refused any coverage of the cost.i suggested they cover half the cluster part, $175.their customer service said, "no."if there is a safety issue, this would be it!i understand there are several lawsuits regarding these speedometers.our vin is on their "silent recall" list. National highway safety traffic administration should be responsible for issuing open ended recalls for safety items such as these.the mission is to protect the public?

2004 gmc 2500 instrument panel defect concerning gauges. Consumer states that the gauges stick and the manufacturer sent out a letter stating this problem and a solution as long as the vehicle had less than 70, 000 miles or 7 years old.the consumer stated the restriction on the time/mileage was unreasonable for any person who lives in rural america.the consumer stated people drive an average of 15,000-20,000 miles per year.

Gauge cluster inoperative.speedometer, oil pressure gauge and fuel gauge giving false readings.

The speedometer on my cluster gauge of my 2004 gmc sierra 2500hd went bad.both my father and brother have 2004 chevy silverados 2500hd and they both received a letter saying that there is a defect in the gauge cluster and both of them had their speedometers go bad and chevy fixed them.of course mine also goes bad and when i take it to a gmc dealer they say there is no recall or defect known and will not fix the problem and now i am driving without a working speedometer when gmc should fix the defect in mine.i knew the cluster must have been going out soon because a month prior the cluster would randomly reset my total engine hours so now i will never even know how many engine hours on my truck even when i do get it fixed.i have less than 60k miles.

The speedometer and gauges such as oil pressure, rpm etc. Are reading wrong and most of the time don't work. This problem is still going on in our 04 gmc sierra.

I have a 2004 gmc 2500hd and the speedometer cluster is all failing so no gauges are starting to work.

The speedometer unexpectedly stopped working on my 2004 gmc sierra 2500 hd as i was driving down i-4.it was registering 65mph one minute, then the next 0 mph.this originally happened approximately 1 1/2 years ago.i contacted my dealer where i purchased thevehicle.t that time, i had approximately 69000 miles on the vehicle.he told me to try and restarting it and it should start working right again.which it did.it has continued to act up since and is becoming more frequent.the dealer now tells me that its is the instrument cluster and needs to be replaced.this isa hazard as when it stops working, i have know idea as to my speed.it is my understanding that this is a know problem by gm and they offered a extended fix option, but did not notify gm owners of this hazard.

While driving speedometer started acting up in cold weather.stopped working.bringing to mechanic to fix.also, fan motor stopped working

Failure of speedometer and oil gauge. Was contacted by gm to replace the instrument panel.because i had more than 70k miles they said it will not be replaced.even though they admit to a failure of the system, since i cannot prove it happened within the 70k mileage they are refusing to replace it.this is a tremendous hazard and is very costly to replace.a dealer quoted me $850.thanks for your help.

The speedometer failed onthe 2004 gmc truck - had no idea of the speed i was going whether iwas in a school zone or on the freeway.just lucky i have not received a ticket.

Speedometer gives crazy readings and never gives accurate speeds.cost to repair is $450to replace the whole gauge cluster.i have seen hundreds of people reporting this problem on the local discussion boards.gm should fix this instead of making money off of defective parts.

The contact owns a 2004 gmc sierra 2500. The contact stated that the speedometer did not function properly and it would indicate a faster speed than he was actually driving. The oil pressure gauge also malfunctioned. The contact previously replaced both driver and passenger side carrier bearings that are associated with the four wheel drive. The contact was able to elevate the vehicle andmove the wheel about a half inch in both directions. The vehicle had not been inspected when the complaint was filed. The contact called the manufacturer but was offered no assistance. The vehicle wasnot repaired. The contact confirmed that the vehicle was a 2005 model produced in 2004; however, the vin displayed that the vehicle was a 2004. The current mileage was approximately 150,000. The failure mileage was approximately 70,000.

I found myself driving 80 mph when my speedometer was reading 65 mph. After keeping track of this it progressively got worse. It reads wrong every time now. Under "number of failures" i am just guessing at a number because it has failed every time i have driven since the fist time.

Im the owner of a 2004 gmc hd sierra truck with almost 74k miles. Im the original owner. Some months back the gas gauge stated showing gas readings way beyond full.it would stay that way for some time before going back to normal than it would fail again. Last week the speedometer gauge went beyond the 120 mile reading and continues to show high speeds -even when im parked. Im concern about danger this failures may cause to me or other drivers on the road. I will contact my local gmc dealer for a fix.

Speedometer shows incorrect readings.at times it will show over 100mph while at normal highway speeds.other times it will read around 60 while driving at least 80 -90 (from rate of passing other drivers on highway).this is a very dangerous situation.apparently gm will repair at no cost but only if less than 70k miles.this vehicle began to show problem around 74k miles.

I have a complaint with gmc. I am having problems as well as others that i know with the 2003/2004 truck. I have a 2004 gmc sierra and my gauges do not work. I will be driving down the highway showing i'm driving 5mph. My oil pressure gage is not right. I talked with different service guys from gmc dealerships and they said they were replacing the panel clusters left and right in these trucks. Gmc will not consider it a recall. It should be!they know about this problem they should be held countable of it. Not the consumer! it should not matter how many miles your truck has. They have a bad part in or installed it wrong they need to fix it.. Thank you so much for your time! i really hope that you can get this instrument panel cluster to become a recall.. Thanks again! p.s. Sry i just put todays date in the incident box..

The contact owns a 2004 gmc sierra 2500 hd.the contact stated that his vehicle fails intermittently.he stated that the speedometer displays incorrect speeds or no speed at all while usually driving 45 mph.he also stated that the tachometer occasionally operates in the same manner as the speedometer.the frequency of the failures is increasing.the dealer stated that there have been numerous failures related to those specific components.the engine size is unavailable.the current mileage is 56,000 and failure mileage was 50,000.

Tachometer gauge rides all over, had transmission checked, okay. Had a scan done, no engine or transmission codes, overdrive does not release when tachometer gauge is erratic, on scan, rpmis normal at about 700, while tachometer shows apprximately3750rpm.being told by chevrolet dealer perhaps a dashboard cluster panel. About $400.00. This truck only has 48,000 miles on it.

Speedometer has failed.does not record speed accurately - significant variation (30 mph or more) for 10-15 minutes, then drops to zero.

I bought (2) sierra 2500 hd trucks that have serious hub assembly problems with one replacement in 2011, lighting system work when it want to and has drain five batteries from aaa and advance auto in the past seven years, abs/engine light stays on since 2007 and after 10 years is gasket problems with gm products. I have talk to gm executive office that fix the hub assembly and tailgate recalls problem in 2011 but unwilling to deal with it now after talking to gm dan. I think i need out side counsel and engineering firm to test and testify on my behaveand 2,300 other owners with the same problem. I want new vehicles and setting up a date with congressional oversight committee, and nhtsa review my case. I have met with congressional panel investigating gmthat want to help me resolve this problem. I been a gm person but seriously looking in the foreign market if i have no serious resolution.

The contact owns a 2004 gmc sierra 2500 hd. The contact stated that while driving various speeds he would hear a loud noise coming from the engine. The vehicle was taken to an independent mechanic for diagnosis where the contact was advised that the manifold bolts were fractured and needed to be replaced. The vehicle was not repaired. In addition, the contact also noticed that the instrument cluster failed and he was unable to determine what speed he was traveling, how much fuel was in the vehicle, etc. The vehicle was taken for inspection where the contact was advised that the cluster wiring failed and needed to be replaced. The manufacturer was contacted however, they offered no assistance. The failure mileage was approximately 50,000. The current mileage was approximately 53,000.

My vehicle had brake lines replace two times with less than 65,000 miles because breaks stop working. Fuel line replaced under 55,000 miles because it made check engine lightcome on speedometer erratic,oil pressure gauge high and low,fuel gauge erratic under 65,000 miles.loud noise from engine service technicianreported the exhaust manifold bolts has broken to call a white smoke from the motor.everything happened with consider to be low mileagein talking to gm they don't care because enough report has not been made.

While driving over 50mph on the highway i get a violent shaking in the engine and the steering wheel shakes bake and forth. The engine sound very loud while its doing this. It only occurs when i am at highway speeds.

Flywheel on four locally owned gm trucks were reported being cracked or broken.old parts are avail.since then speedometer doesn't work properly and i am told there's no problem.

Excessive rust on frame of truck, oil lines and gas lines are constantly rusting out. The truck is a gmc k-2500 h d extended cab, 2004 with 34,500 miles on it. Presently waiting for the cooling lines from the oil filter to the radiator which are leaking oil on the exhaust which could cause a fire, when draining oil to change it the oil [removing the plug] follows onto the hot exhaust pipe,another fire hazard. What can be done, can't afford another truck now.

Broken exhaust manifold bolts causing excessive noise and emissions issues.

Left and right sides rear exhaust manifold bolts broken off.it leaks exhaust, may be a fire hazard and could cause emissions failure and emissions components failures.this problem is on a 2004 gmc 6.0 engine.noticed ticking noise at about 38000 miles and it would go away after 30-45 seconds.a gm rep said it was most likely the skirt less pistons and not to worry. Had some work done at a garage about a week ago and mechanic pointed out the broken bolts.

Bolts that hold exhaust manifold are breaking 3 are gone alreadyi just noticed it today because i heard an exhaust leak unknown how long this has been going on.

My ignition also switches off due to the key chain being to heavy, i would like my vehicle fixed as well. I think gm is not telling the whole story on how many vehicle are affected by the ignition switches. I can prove my claim by attaching my two key chains together again and the problem will occur again.

A/c does not cool properly. I have been to the dealer twice for this problem. First time vehicle was still under warranty. There is a tsb out on this problem and dealer insisted that a/c was cooling properly. Now that the vehicle is out of warranty, it still has the same a/c problem. The vehicle now needs a $175 a/c service, tsb still not performed. My vehicle met all the criteria to have this performed before my warranty ran out, and still does.

The contact owns a 2004 gmc sierra 2500.the contact noticed that while applying pressure to the brakes the steering would become difficult to move.when attaching the wiring harness to the trailer the tail lights would not illuminate.the dealer informed the contact that there were no related recalls.the vehicle had not been repaired.the current mileage was 73,000 and the failure mileage was unknown.

Diesel power keeps reducing. Truck has been to dealer twice. All maintenance is performed per owners manual, including fuel filters. Truck has been to dealer twice for this problem. I suspect injector failure or other fuel system problem. At 5000 miles the previous owner had a new injector pump replaced. I feel that this makes the vehicle unsafe to trailer with. I have trouble maintaining speeds on even the smallest of grades not towing much weight. I have contacted gm, which was less than helpful. Dealer insists that it needs the "throttle body cleaned", no throttle body on a diesel! truck is now going to a recommended, competent medium duty dealership.

Allison transmission housing failed at 54,000 miles. Gm paid parts, i paid 1,200.00 labor , was toldthat there was 2 bulletins out on defective housing and when they finished repair they said they installed updated housing so i would not have problem again. Don't think i should have paid anything to have it repaired! at 105,000 miles transfer case failed , cost 1,150.00to repair, have had to take back 2 more times as repair was not done right. At 112.000 miles speedometer becameerratic was told it was a common problem ,and see on complaint search it is , consider this a great safety danger as i do not know what speed i'm going can only guess not fixed yet found some who sells rebuilt ones foe 150.00 ,said their rebuilding them due the large number that are failing. Also at 112,000 miles park neutral switch started acting up ,check engine light on ,shift bar light goes away, truck won't shift properly and stay in certain gears without shifting up ,effects door locks. Looked up park neutral shift as part and came across bulletins stating that during left hand turn front tire sprays water onto park neutral ,switch causing problem ,needs front & rear shield installed to solve problem. Have taken truck back in waiting for information. Also around 90,000 miles had very hard time starting truck and truck ran poorly,problem became worse took in, fuel injectors were bad and were replaced under warranty at 112,000 miles no need to say i'm not a gmc fan anymore , even though i live in lansing mi ( a gm town)and have lots of friends and family employed there. Good by gmc! never again.

Fuel leak.fuel pump leaking cause fuel to be spew out over engine and under carriage.

Diesel fuel leaks from injectors into engine oil pan and contaminates engine oil them leaks oil from breather & rear main oil seal and gm knows there is a problem but wont do any thing for this problem said its out warranty on time not miles.

I was leaving a parking lot, and as i hit my brakes, there were no brakes.i limped home, using the e-brake and transmission to keep the truck under control.upon inspection i found the front brake line rusted and leaking.

The contact owns a 2004 gmc sierra 2500 hd.the contact performed routine maintenance on the vehicle and observed that the transfer case (4 -wheel drive) contained pinholes, which led to an internal fluid leak.the transfer case fluid level was completely empty.the locking clip failed, which contributed to the failure.the vehicle was taken to an independent transmission shop and the technician replaced the locking clip.the failure mileage was 120,000 and current mileage was 126,000.

I was driving my 2004 gmc sierra with my car seat warmers on.i suffered 1st and 2nd degree burns to my back from the car seat warmers.i had only been driving the car for approximately 20 minutes.the pain worsened, and i immediately sought medical attention. I reported this to gmc claims on the same day.i had pictures taken of my back on the day of the injury, and 2 days later.gmc claims on feb 26th told me my car seat temps (raytech 120.1 f with leather on;170 f with leather off) are within normal range and this claim does not actually even need to be settled by gmc.these temperatures were taken by gmc's investigation specialist.i witnessed the investigation.i spoke to a forensic engineer on march 5, 2010, who stated the temperatures read from the raytec are inaccurate as they were not done during compression of the car seat to simulate sitting in the seat.this forensic engineer informed me that the accurate temperatures would have been higher .i have not tried the seat warmers since my injury, because i do not want to incur further injury or possibly worse, such as a fire hazard.at this point, the claim is ongoing.i am very upset with gmc and their handling of this claim.it seems that the safety of myself and my family are being disregarded.

The contact owns a 2004 gmc sierra 2500. The contact stated that the drivers side heated seat system became so hot that it was impossible to remain in the seat.when attempting to adjust the seating function and move forward it would roll backwards and when attempting to adjust the seat backwards, it would move forward.both the dealer and manufacturer informed the contact that there were no related recalls. The vehicle was not repaired.the current mileage was 73,000 and the failure mileage was 45,000.

Brake lines rusted and leaking.

Leaving work i pulled out from the parking lot and drove about 500 yards.went to apply brakes and pedal went to the floor.i was able to make it back to my work parking lot and stopped the truck.noticed that brake fluid was pouring from under the truck in two places.one leak was under the drivers area and the other was in front of the left rear wheel.the place i work has a car lift.put the truck on the lift and the brake lines were rusted through.the truck has enormous amounts of rust on the frame, suspension,and axles.this truck is not my daily driver.i do not live near the ocean nor do i push snow with it.i have never seen brake lines rust out like this.gm stated that i had to take it to a dealer for inspection.after reading up on the topic i know gm won't do anything about the lines.i already ordered stainless steel brake lines for the truck and will install them.hopefully gm will reimburse owner for this expense.

Pulling out of a parking lot, lost brakes.steel brake lines by fuel tank, let go causing truck to loose brakes

My brake lines rusted at the rear of the lt front wheel splash area. This vehicle has low miles for the year and was not driven in salt or deice. The brake line should not need to be replaced at this time with so much service life left. I was lucky, the brake line burst in my driveway.

The contact owns a 2004 gmc sierra 2500 hd. The contact stated that while driving 40 mph the vehicle began to shake violently. The contact mentioned that the vehicle was merged to the side of the road and after a few minute restarted the vehicle but the front wheel was locked and smoke was emitting from the hubcaps. After a considerable amount of time the wheels unlocked and the vehicle was driven to a dealer for diagnosis. He was informed that the seal in the boost had leaked and contaminated brake fluid and locked up the system. The vehicle was repaired. The failure and current mileage was 140,894. Updated 12/19/12 the consumer statedwhile traveling 40mph the vehicle stared losing power. Upon further inspection it was found the brakes were smoking. After the smoke settled, the consumer attempted to press the brake pedal. It would not move. After about 3 hours the brakes released. The vehicle was then driven t a repair shop. Updated 1/9/2013

I was leaving a parking lot, and as i hit my brakes, there were no brakes.i limped home, using the e-brake and transmission to keep the truck under control.upon inspection i found the front brake line rusted and leaking.

The contact owns a 2004 gmc sierra 2500 hd. While driving 10 mph, the brakes failed without warning. It was diagnosed that all the brake lines needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 176,395.

The contact owns a 2004 gmc sierra 2500 hd. The contact stated that while driving 40 mph, he applied the brakes but the vehicle did not respond. He continued applying pressure until the pedal touched the floorboard and finally, the vehicle came to a stop. The vehicle was taken to a dealer for diagnosis and the contact was informed that the steel brake lines exhibited massive corrosion and were leaking. The vehicle was taken to a different dealer where the repair was completed. The manufacturer was notified of the failure. The failure and current mileage was 80,000.

While traveling on the pa turnpike at approx. 60 mph, traffic suddenly slowed in front of me. I was pulling our 30 fifth wheel camper at the time. I applied the brake hard had a split second of braking action and then the brake pedal went to the floor. I was able to use the manual trailer brake control to slow the truck some, swerved into the left lane missing the car in front of me by inches and the car to the left of me swerved into the far left lane to avoid hitting me. (three lane highway) i managed to drive the truck to a rest area about a mile down the road using both the trailer brakes and the truck emergency brakes. The cause of the brake failure was that the brake line located under the drivers area had rusted through and ruptured.

The contact owns a 2004 gmc sierra 2500 hd. The contact stated that while driving 25 mph downhill, the driver was attempting to brake and the pedal depressed to the floor. The contact mentioned that the failure occurred twice before. The vehicle was taken to the dealer, who diagnosed that the brake lines were completely corroded. The manufacturer was made aware of the failure and did not offer any assistance. The vehicle was not repaired. The failure mileage was 33,000 and the current mileage was 36,000.

My vehicle had brake lines replace two times with less than 65,000 miles because breaks stop working. Fuel line replaced under 55,000 miles because it made check engine lightcome on speedometer erratic,oil pressure gauge high and low,fuel gauge erratic under 65,000 miles.loud noise from engine service technicianreported the exhaust manifold bolts has broken to call a white smoke from the motor.everything happened with consider to be low mileagein talking to gm they don't care because enough report has not been made.

During cold mornings (wisconsin) i start my truck and i have no power steering and soft brakes. It is my understanding that the power steering runs the brake boost.also, it is my understanding that there is a service bulletin that says that the power steering fluid should be replaced with low/cold temp fluid.my concern is what happens if i lose power steering and brakes while i am driving.

Rusty brake lines on 2004 gmc 2500hd sierra.almost caused me to have an accident because the brake petal went to the floor immediately when the brake line burst.i have pictures of the old rusted brake lines if you would like to see the pictures.since it seems to be a wide spread problem on gm pickup trucks from researching it on the internet, i'm curious to know when they are going to recall them?just saw on the news where there is a government recall on 2005-2009 subaru's for the same problem.it cost $1290.00 to repair all the brake lines.

Brake pedal went to the floor. Almost impossible to drive like that. Takes over 100x longer to stop a 3/4 ton truck. I found that the brake lines rusted out. I also found several hundred reports of the same things on gm truck online. I also heard you were investigating this issue already. I wanted to make sure i am counted as one of the effected people. I also read where gm does not consider this a safety issue. I disagree. The line from the master cylinder to the abs unit blew so i had zero brake pressure and pedal. I think this should be recalled as it is a huge safety issue. I have already spent over $1000 and a week trying to fix this and replace all the rusted line. I still do not have the truck back on the road.thanks

On 9-19-2014 the truck was stopped at a red light and started to inch forward. Slight pressure on the brake pedal stopped the movement. The event was so quick and slight i thought nothing about it. I turned on the freeway and drove 30 or 40 miles before touching the brake pedal again. When i did it went almost to the floor without slowing the truck speed any appreciable amount. At that point i knew i had a serious problem. I geared the truck down and was able to avoid being involved in an accident.if i had needed to come to a full and fast stop it could easily have been a disaster.an internet search revealed gm has had this problem for some time without notice to truck owners that it exists. An inspection of the brake lines was done and indicated a failure in the brake line system due to rust. The fuel lines showed the same kind of deterioration. Pictures can be provided to verify the lack of advanced rust conditions to the underneath of the truck other than the brake line system, the fuel line system, and the drive shaft.the truck was purchased new in south carolina and has been driven there 90% on the total mileage on it.

This seldom used, well maintained, garaged truck, blew out the brake lines on left side on the frame, under the door, resulting in total brake failure. I had to use the parking brake to stop the vehicle. I was on my way to pick up a #9000 boat. If i had that boat behind the truck, it could have killed me, or others on the road. Brake lines are not a normal service part. Replacing all the brake lines is costing me 1300, at a minimum. My neighbor next door has a similar 2004 gmc sierra, with about the same mileage, only his is a 1/2 ton, where mine is 3/4 ton. His truck had the same failure the week before, in the exact same location on the lines.do a simple search looking for brake failures on these vehicles, and you find that its well documented. This should be a recall before people are killed. There is no way that i should be looking at brake line failure on a 10 year old garaged truck that has a tow capacity of over 10,000 #'s. How should someone detect the integrity of the brake lines to determine when the should be replaced?

On 2/1/2015, at approximately 11:30 am, i was stopping at my brothers mailbox to get his mail while he was on vacation. Wheni went to stop at his mailbox, the brake pedal on my truck went to the floor with no resistance on the pedal. I pumped the brakes several times, put the truck in neutral and it came to a gradual stop over an extended braking distance of 20 to 30 feet (which is slightly uphill). There were no lights lit on the dash and the master cylinder was between the maximum and minimum levels on the reservoir, when i examined it after the occurrence. We live on a dirt road without much traffic, so i placed the truck in low range 4wd and drove it the 1/2 mile home. Upon returning home the top brake line which runs along the frame from the anti lock brake block back towards the drivers side rear of the truck had ruptured. The brake fluid in the master never went below the minimum level, so i attempted to refill it to see if i could get any brake pedal pressure back. The pedal went to the floor still after multiple tries with a full master cylinder.the brake line had ruptured where it is attached at a green plastic factory hanger. The brake line was corroded/rusted where it had failed. If i would not have stopped at my brothers mailbox, it is 1 mile down hill on an approximate 12 degree grade to the main road. The intersection at the bottom of the road is a 90 degree, t intersection in a creek bottom, where i am supposed to stop prior to entering the main road. We had just came home on 1/31/2015 from a 8.0 hour round trip to see my son at college through the mountains of maryland and west virginia on i-68 and had driven various major busy highways including i-79, i-68 and i-81. Due to the amount of fuel which we would have used, we decided to take my other son's wrangler on the trip or i may have been sending this email from the hospital if we were lucky.

Complete brake failure, when brake line blew out while trying to stop.prior to hitting car in front, swerved into left turn lane and applied emergency brake.

All the fluid lines corroded to the point where the vehicle was dangerous to drive with only 35000 original miles on it.

The contact owns a 2004 gmc sierra 2500 hd. The contact was driving 25 mph and applied the brakes for a traffic stop when there was a pulsation coming from the brakes. This caused the brakes to be depressed abnormally into the floorboard. The contact could not stop the vehicle until he engaged the emergency brakes. The vehicle was driven to the dealer and after inspection, the dealer informed him that the brake line was rusted and had ruptured. In addition, the dealer advised that there were no recalls for the failure.the manufacturer was contacted who advised that a representative would later return his call. The vehicle was not repaired. The failure mileage was 42,000.updated 09/28/2011 *ln

1.applied brakes when leaving driveway.2.brakes failed completely.3.brake lines completely rusted out.right front failed allowing brake fluid and requisite pressure to escape.i replaced the failed section.

Lost brakes while driving 35 mph was able to stop and noticed brake fluid dripping from above gas tank just forward of rear axle on drivers side.new brake line was installed at gmc dealer in july 2010 after it burst going 45 mph same problem as in july 2010 that caused an accident with property damage to my vehicle and others property after sudden complete brake failure. New line is severely corroded at each green plastic clip after only 7 months.

The complaint is that the brake lines failed and are made of very poor material. The brake line failed on my way to work one day on march 10,2015.

This complaint covers my 2004 gmc sierra 2500hd crew cab 4wd.almost one year ago i had a main brake line blow underneath the drivers side of the truck.the line was so corroded it was no wonder.this incident happened on 9-7-10.i was hooked to my fifth wheel camper and was preparing to pull out of driveway and when i placed foot on brake to shift into drive it blew.thankfully i was just beginning to move. I had the truck towed to my local mechanic and he replaced the line and flushed system.now again on 8-22-11 same situation occurred.the line blew in exactly the same position as first time only a different line this time.not to mention the other corrosion on the brake calipers and hardware that rendered my rear brakes useless.had to replace rotors and pads due to sticking brake pad wearing to point of metal to metal contact.did i mention i purchased this truck new and it now has only 38,500 miles.rarely does it get driven in snow and salt.i have all receipts for parts that this problem has caused me.im just thankful that i wasn't towing as i usually do when im driving this truck.i've talked to my local dealership don hall in ashland, ky and they cite hundreds of trucks having this same problem.when are they going to do something about this.i am a loyal gm fan but i worked at a toyota dealership for two years selling used vehicles.i made it a habit of checking all of our gm truck trade-ins for this rust problem and they too had this.i saw even two to three year old vehicles rusted to the point of collapse.one of these being a $65000 cadillac escalade.appalling.

At slow speed as i'm coming to a stop i'll feel the abs brakes kick inand the pedal will go down some more and steering wheel kick to the left and the truck will move alittle farther instead of stopping.

The contact owns a 2004 gmc sierra 2500 hd.the contact stated that both rear brake pads and rotors were worn, in addition to the front passenger side brake pad and rotor.the contact feels that the brake pads and rotors should not have failed at 36,000 miles.the manufacturer took a report and stated that the failure was not a defect, but rather a part of normal maintenance.they refused to assist with the repair.the vehicle has not been repaired.the current and failure mileages were 36,000. Updated 11/14/08 the consumer stated the brake pads would not move on slides. Updated 11/19/08.

My truck is a work truck driven by an employee, i have just recently become aware of a condition regarding the instrument cluster, wherein the whole panel does not work, i was advised by the employee that this happened quite some time ago, but was never made aware.i contacted gmc but apparently, because this is considered a special policy recall (only if someone complains - and within a specified time period 7 yrs or 80,000 miles) they will not repair this defect.i never received a notice, nor was i aware of the problem within that time period.i was further informed by my worker that at the time the panel went out, the fan for the heater/air condition unit appeared to smoke and now it does not work.here again, i have not received any recall notices for this defect either. Finally, in my attempts to get the cluster repaired, i have been informed that there is a recall on the hydro boost accumulator... I have not once received a recall notice on this vehicle and i purchased this vehicle new.my vehicle has 101,000 miles on it.you would think that a vehicle of this nature would last longer than 100,000.but apparently not... Also, when these is such a major recall out on a vehicle you would think that gmc would contact you and advise you of this problem..

While towing 4000# boat, approached traffic signal and applied brakes while moving at approx 10 mph, the brakes applied and the pedal then bottomed out on the floor. The vehicle veered left and came to a stop after much continued braking effort.the vehicle was driven off the highway at the first safe intersection and examined. Inspection under the drivers side of the frame revealed rusted through steel brake line from master cylinder and leaking brake fluid onto the street. Vehicle and boat were towed, later inspection revealedfour of five steel brake lines at the proportioning valve were rusted to point that replacement was necessary.

Brake lines are rotted out. I pushed on my brake pedal while coming to a red light and it went to the floor, the rusted lines had broken and my brakes did not work. Luckily i was not going to fast or to close to the car in front of me so i was able to slow enough to turn off the road by pushing in my parking brake.

The contact owns a 2004 gmc sierra 2500 hd. The contact stated that while driving approximately 50 mph and attempting to decelerate, the brake pedal went straight to the floorboard abnormally. The vehicle was taken to a dealer where they advised him that the driver side rear steel brake line had failed. They advised him that all brake lines needed to be replaced due to the severity of the corrosion.the vehicle was not repaired. The manufacturer was contacted and they offered no assistance. The failure and the current mileages were approximately 38,400.

Wife and child driving truck, brake pedal went to the floor and service brake indicator came on while on interstate. Stopped at a gas station and filled master cylinder reservoir with fluid. Drove vehicle 8 more miles and traded with me, when i got to the vehicle, i found brake fluid leaking onto ground, found lines corroded beyond belief on driver side frame around wheel well. Drove truck home using emergency brake, low speed, and down shifting. No repairs have been performed due to strong belief this is a manufacturer defect.

I own a 2004 gmc sierra 2500hd 4wd truck.it has 90,500 miles on it.multiple brake lines under the driver side door have rusted and are leaking brake fluid.the vehicle is unsafe to drive at this point unless repairs are made costing me over $1000.i cannot drive the truck until repairs are made.it appears after doing some online research that there is already a nhtsa investigation concerning premature brake line rusting/failure on gm trucks.i have driven cars that are over 30 years old and they do not have the kind of rust i have on my gmc sierra that is only 7 years old!!!please make gm do a recall on this design failure.they are endangering the lives of their customers!

I was approaching an intersection in my 2004 gmc sierra 4x4 2500hd pickup truck with a 2800 pound trailer when i pressed the brakes to stop.the brake pedal went to the floor and i was unable to stop.the trailer brakes were not enough to stop the vehicle and i continued into the intersection and was almost struck by two other vehicles.they just missed hitting my vehicle and causing serious injuries to myself and my passenger, as well as themselves.when i opened the hood there was brake fluid all over the drivers side of the engine compartment.i had the vehicle towed to the nearest gmc dealer.the dealer told me that a brake line had burst and needed to be replaced.he also stated that all the brake lines were corroded and needed to be replaced at $750.00 per side.he told me that this was a common problem for these vehicles and that these lines only last 4-7 years on average.there is also significant corrosion on the frame.my vehicle is always garaged and regular maintenance is done.the dealer then told me that since we live in a snow belt state that i should expect this and that gmc will not help with the repair.i told him that i am very upset and that i have been a firefighter/paramedic for over 25 years, and if what he just said was true, then i would have had to rescue an awful lot of people from their crashed vehicles if on average brake lines only lasted 4-7 years. I feel that this needs to be reported and investigated because it is a very serious safety issue and people are going to get hurt if what the dealer told me is true.i would appreciate it if you would look into this matter.at this point my vehicle is sitting at the dealership in an unrepaired condition until further action by either gmc or nhtsa happens.

Dt*:the contact stated that the vehicle experienced excessive stopping distance while depressing the brake pedal.the dealer could not duplicate the problem.

The contact owns a 2004 gmc sierra 2500 hd.while driving 30 mph, the brake pedal extended to the floorboard when depressed.the dealer stated that there was rust on the bolt that attached the wheel sensor.as of september 12, 2007, the dealer had not repaired the vehicle.the failure mileage was 40,000 and current mileage was 58,800.

The contact owns a 2004 gmc sierra k2500 hd.the contact stated that the anti lock brake system failure was similar to nhtsa campaign id number: 05v379000 (service brakes, hydraulic:antilock).the dealer replaced the brakes in 2008; however, the failure continued to occur.the manufacturer advised the contact that his vehicle was not included in the previous recall and offered no additional assistance.the current mileage was 29,000 and the failure mileage was 24,000.

When slowing using the brake system, the vehicle actually loses braking effectiveness for a short time (less than 1 second) just before the vehicle actually stops- at about 3 to 5 mph. The is then a pulsing feel in the brake pedal and the vehicle then stops.the point is that there is actually a momentary loss of braking effectiveness in the last few moments of a normal stop. Fortunately, them, only "low speeds" are involved; unfortunately, this is very unsettling when stopping at a busy intersection or in congested traffic. It leaves one wondering if/when the brake function will actually fail altogether.i had the problem investigated by my dealer and was told that it involved the anti lock sensors which may be fixed by cleaning. If that wouldn't fix the problem, the sensors would have to be replaced.costs: cleaning $160; replacement: $1250.cleaning did not correct the problem.

Clunking noise in steering components when turning the vehicle with suspension movement (crown of road, un-level surface). Clunking felt in the steering wheel. Dealer stated, intermediate steering shaft problem. Many like reported problems to dealer and on the internet.

Steering linkage problems: i've had the same problem since i've owned my truck.my father, who also has a 2500hd, has the same problems as well.they lubed and greased the shaft at one point under warranty, but the problem has returned and is persistent in both of our trucks.both of our trucks are '04 models and i have less than 40k miles on mine.it feels like the steering wheel will come unattached from the linkage.not a very safe problem to have.i hope someone will take these complaints seriously.

The contact owns a 2004 gmc sierra 2500.the contact noticed that while applying pressure to the brakes the steering would become difficult to move.when attaching the wiring harness to the trailer the tail lights would not illuminate.the dealer informed the contact that there were no related recalls.the vehicle had not been repaired.the current mileage was 73,000 and the failure mileage was unknown.

During cold mornings (wisconsin) i start my truck and i have no power steering and soft brakes. It is my understanding that the power steering runs the brake boost.also, it is my understanding that there is a service bulletin that says that the power steering fluid should be replaced with low/cold temp fluid.my concern is what happens if i lose power steering and brakes while i am driving.

Intermediate shaft continues to rattle. Was fixed under warranty once. Vehicle is now out of warranty and cost $110 to lube the shaft, which isn't even guaranteed to fix the problem. Many people have this problem with their trucks over and over. Gm needs to handle the problem correctly.

Excessive rust on frame of truck, oil lines and gas lines are constantly rusting out. The truck is a gmc k-2500 h d extended cab, 2004 with 34,500 miles on it. Presently waiting for the cooling lines from the oil filter to the radiator which are leaking oil on the exhaust which could cause a fire, when draining oil to change it the oil [removing the plug] follows onto the hot exhaust pipe,another fire hazard. What can be done, can't afford another truck now.

All the fluid lines corroded to the point where the vehicle was dangerous to drive with only 35000 original miles on it.

The contact owns a 2004 gmc sierra 2500 hd.while driving approximately 55 mph, the contact felt excessive wobbling on the hubs of the vehicle.the dealer stated that the front wheel bearings needed to be replaced.the bearings were repaired.he filed a formal complaint with the manufacturer.the current and failure mileages were 90,000.

#1. Hvac system with a/c on drivers side ( only) will go into full heat , if you shutoff engine and restart system will be fine again for sometime, there is no set pattern as to when this will happen sometimes a day or a week sometimes a month.#2. Drivers side window will not work , like above sometimes it works fine than it wont work for a few minutes or for a day.

I bought (2) sierra 2500 hd trucks that have serious hub assembly problems with one replacement in 2011, lighting system work when it want to and has drain five batteries from aaa and advance auto in the past seven years, abs/engine light stays on since 2007 and after 10 years is gasket problems with gm products. I have talk to gm executive office that fix the hub assembly and tailgate recalls problem in 2011 but unwilling to deal with it now after talking to gm dan. I think i need out side counsel and engineering firm to test and testify on my behaveand 2,300 other owners with the same problem. I want new vehicles and setting up a date with congressional oversight committee, and nhtsa review my case. I have met with congressional panel investigating gmthat want to help me resolve this problem. I been a gm person but seriously looking in the foreign market if i have no serious resolution.
