Crash, injury,frontal impact, brakes did not respond quickly enough.air bags did not deploy.

I bought my gmc sierra 2500 in june of 2005.shortly after i bought the truck i started to notice rust on the trailer hitch and frame rails.as the years have gone by, the entire undercarriage is rusted over.over the last several years a brake line rusted through and the brake pads & rotors have been replaced several times.i was lucky to be picking my truck up from the shop after an oil change & not driving it, when i noticed brake fluid on the ground under my truck.my speedometer does not work properly & the dashboard lighting works occasionally. My trailer hitch rusted so bad that the last time i put the receiver into the hitch it was stuck & i had to get a friend to connect a chain to his truck & while i drove forward & he reversed, the receiver finally broke free after approx. 10 minutes.

Lass then 50000 mil the speedometer stop working it need a new ( instrument panel )

The contact owns a 2005 gmc sierra. The contact stated that while the vehicle was parked and turned off the fog lamps activated independently. While inspecting the vehicle it was discovered that the driver side dashboard had melted and a burning odor was present inside the cabin of the vehicle. The fire department was not notified. The cause of the failure was not yet determined. The manufacturer and local dealer was not notified. The failure mileage was 160,000.

Fuel gage,speedometer broken, oil gage , battery indicator etc all stopped working.also steering column has been fixed three times and broke again.

2005 gmc 2500hd pickup truck, hvac blower speed controller/relay connector got hot, burned out connector and wire, lots of smoke. It happened when turn fan to high. The failure was due to contact resistance at the connector. The wire harness end is tinted copper, the relay/controller connector is bare metal. Due to galvanization of different metal in the connection system, the connector is undersize for the black wire, which is the return current because the blower assembly is plastic. The resistance between the contact point of the connector act as heater and got hot, burn out connection and connector housing. The speed control unit, which composed of few power resistor is mounted in the air stream that it will collect vapor water due to condensation when ac is in used. This cause corrosion in the speed controller/relay board. The work around is bypass the connector by shorting the black wire from the blower motor to the black input wire that burned out. Cut the input black wire, wire nut it together with a 12 awg jumper wire, cut the black wire at the blower motor, wire nut it to the other end of the jumper wire. After the jumper put in, blower fan works in all speed and no smoke from connector and wire.

The contact owns a 2005 gmc sierra 2500 hd. The contact stated that the speedometer would not provide accurate speed rates. The speedometer would read that the contact was traveling 120 mph when the contact was actually traveling 60 mph. The contact had not taken the vehicle to the dealer for inspection or repairs. The current mileage was 102,000 and the failure mileage was unknown.

The speedometer is failing.it works erratically.it eventually goes to zero and stays there until i stop and restart the truck or let it sit overnight.

Speedometer quit working while driving. Shows 75 miles an hour while stopped goes up to 120 on acceleration. No way to know actual speed.

I have a 2005 gmc sierra 2500hd crew cab 4x4 with the 6.0 engine and 5 speed manual transmission.everytime i come to a slow stop the abs unit engages and reduces pedal pressure, causing the brake power to fade and increasing the distance of my stop.

All exhaust manifold bolts are defective causing them to break, when they do the exhaust manifold separates from the cylinder head in turn directing all emissions from the engine into the air, and cabin of the vehicle. This could cause a fire if not corrected. One spark would set the vehicle on fire.

While traveling west of denver, colorado my 2005 gmc sierra 2500hd equipped with the duramax diesel overheated to the point of the vehicle shutting down. This happened on a stretch of highway where there was no shoulder to pull off on resulting in an extremely hazardous condition. I have done extensive on-line research and have found this to be a common occurrence with the 2004.5 and 2005 model year chevrolet and gmc hd series trucks equipped with the diesel motor. Numerous people have taken their trucks to local chevrolet and gmc dealerships but gm has been unable or unwilling to help thus far. These trucks are creating dangerous situations that i fear will result in serious injury or death.

Factory sylvania running light bulbs to hot and scorching/melting theplastic sockets in gm pickup trucks. 2005 to 2009 that's why you see so many gm trucks including cadillac escalade with one or both of the day time running lights not working the socket has melted from the heat of the light bulb.

The 2005 gmc 2500hd fwd(well maintained and oiled to prevent corrosion) experienced a failure while towing my 24' pursuit fishing boat (7200 lbs.) home from sturgeon point marina to hamburg, ny 14075 (approximately 10 miles) with "minimal" stopping capability as the dot 3 brake fluid was being expelled. I had to feature the throttle to negotiate stopping senarios without issue. As of 8/20/12, this vehicle is with fuccillo chevrolet, inc. (grand island, ny) for overhaul of entire braking system; including fuel lines. The certified technician suggested the entire brake lines system be replaced along with the fuel lines due to extreme corrosion. All this work is being performed since the excellent condition of the vehicle.the estimate for this work is approximately $2250 to replace all lines (brake / gas) affected by severe corrosion. This condition is a result of poor material selection not capable of withstanding normal winter conditions found in the northeast. The same standards should be used as selecting exhaust system material. Brakes can kill you....exhaust systems can not!final note: truck driven 50 miles per week to work (10 miles each day). During winter months, the residual salt is rinsed as required on a weekly basis (or sooner) to prevent corrosion. This truck prior to winter driving has had oil applied to the underframe, apparently, the brake / fuel line where not adequately treated.

The contact owns a 2005 gmc sierra 2500. The contact stated he replaced all the brake lines on the vehicle and also stated that the body frame of the vehicle was corroded. The vehicle was taken to an independence mechanic where all the corroded brake lines were replace. The vehicle was not diagnosed. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 61,000.

Started the truck and applied the brakes to shift into gear and the brake pedal went to the floor.after several times pressing the pedal there was no brakes at all.the truck was towed to the dealer where i was informed all the brake line were rusted and needed to be replaced at a cost of $1,300.00.the truck only had 35,000 miles on it.if i had been driving, i am sure this would have likely caused a serious accident.

Blew out one brake line lost all brakes no backup,pedal went all the way to the floor.54,000 miles all lines rusted all needed to be replacedthank god i just pulled into a parking lot.

While driving down a country road in my pickup truck my brake lines failed in 2 spots due to rust and corrosion. I was pulling a trailer also. Very very dangerous. Lucky to have acted so fast in using the emergency brake.

After putting the vehicle in park and proceeding down my driveway, the abs lights began flashing and chiming on the dash.i pushed the brake pedal and it went to the floor.i stopped the vehicle with the emergency brake.i got out of the vehicle and noticed brake fluid dripping underneath the truck.i crawled under the truck and found the left rear brake line had corroded through just above the fuel tank.i called the dealer and he stated this is a known defect from gm.he said i needed all brake lines replaced and gm's new parts had an extra coating to prevent corrosion.it cost me $1100.this type of failure seems way too soon for a truck with 38,000 miles.

I was on my way to work and i lost all brakes,took it to a mechanic ,he informed me it was rusted brake lines.

Brakes failed while driving due to metal brake line corrosion causing an accident.police report:mooresville, indiana pd #a17315

2005 gmc 2500hd that the brake lines failed. After checking they are rusted everywhere. I looked on the internet and i see that this is a ongoing issue with this model year.

Taking vehicle out of park brake pedal went all way to floor because steel line ruptured causing massive leakage of brake fluid, rolled out of drive way into street cutting wheel to avoid wreck before could get in neutral and roll to stop !

Brake pedal went to the floor.inspection discovered that all the vehicle brake lines were rusted, some to the point of leaking brake fluid.

While driving to work approaching an intersection the car in front of me signaled to turn right last minute and applied the brakes, i also applied the brakes and the pedal went all the way to the floor. If i didn't have enough following distance i would have crashed right in to the car. I only had about 1/2 inch of brake pedal and drove in low gear very carefully the rest of the short distance to work. When i got out of the truck i saw brake fluid pouring out of the brake lines below the drivers side door and they were completely rusted out. Upon further inspection i realized all my brake lines were rusty on a nine year old vehicle, i never saw anything like this before. I had to get the vehicle towed and repaired at a local garage that charged me $1,547.61 to replace all the lines and did a horrible job. I had called the gmc dealer i dealt with in the past and they were inundated with recall work and had at least a 2 week wait and another gm dealer that gmc customer service provided me and they were also all booked up with recall work and so i was forced to trust a local shop. This a safety issue that could get people killed, i always have my wife and kids in the truck and it was a death trap. In talking to gmc reps is seems they have no intention to reimburse me for this premature and accelerated rusting condition that could have caused me or someone else their life.

I have a 2005 gmc sierra 2500hd crew cab 4x4 with the 6.0 engine and 5 speed manual transmission.everytime i come to a slow stop the abs unit engages and reduces pedal pressure, causing the brake power to fade and increasing the distance of my stop.
