Vehicle involved in a head on collision at 30 mph, vehicle that impacted my vehicle was travelling at 25 mph. The entire front of car including bumper was destroyed by the 55 mph impact. Neither airbag deployed. The driver airbag appears to have begun to deploy, but did not.

Driver rear ended another vehicle at 30 to 35mph, and neither driver'sside nor passenger's side airbags deployed. Dealer has not seen vehicle.

Cannot hear horn inside the car how can you expect anyone else to, it only has one horn prevouis years had two.

The first incident occurred on 2/20/2001.estimated speed was 35 mph.the ignition fuse blew and the entire car went dead.i was not using any other electrical component in the car at the time (i.e. Radio, lights, etc).towed to dealer who determined the problem.they kept it for several days and the problem did not reoccur.a few days after i got the car back, the very same thing happened.this was on 2/28.again towed to the dealer.again replaced the fuse.again kept it for a week and drove it continually with no problem.i got the car back on friday, 3/9.on sat. 3/10, after having driven 65 miles at about 75 mph, i was driving in town at about 45 mph.the fuse again blew.i had a replacement fuse, which i had requested from the dealer, and replaced it myself.i am taking it back to the dealer today, 3/12.

Intermittent when makingright turns vehicle stall dealer has been contacted. Please provide further information. Ts

My wife and i noticed antifreeze odor coming in through vents.when our windows would fog, our defroster wouldn't work.then our passenger side floor was soaked with antifreeze.we took the car to the dealer, our heater core was leaking.cost was $1300 to repair. Mitsubishi should be held responsible!!too many complaints.

The fumes of antifreeze fogged up the windows severely, reducing visibility of the driver. It was raining one night and my windows all of a sudden got foggy.i turned on the defroster, which made my windows even foggier.the poor visibility caused me to run off the road into the grassy median.i was out of town when this occurred.in doing research on this problem i found that it was common all diamantes (92 -2001).in many cases, the driver is not aware that this is a severe problem.the antifreeze will started leaking on the passenger?s side area.causing more strong smell of toxic antifreeze.i believe this to be a safety issue.

The vehicle jerked as if it was going to shut off and sometimes itcompletely shut down intermittently.

On two occassions, this 2000diamante shook violently, belched blue smoke out the exhaust, lost considerable power, filled the interior with hazardous fumes and the service engine light came on. These two life threatening events happened at a little over 4000 miles and 12000 miles. My telephone number is 760-323-0704, your questioaire allows one to view all info before sending but does not allow adding information that one might have missed.

After being stopped a couple of minutes because of a passing train, when proceeding, the car would not move more than, probably, 5 mph.noticed a smell coming in, like oil burning.didn't see no smoke coming out of hood.check engine light came on.parked car and got out to see black smoke coming from behind the car.turned off engine and tried to turn on to move car, it wouldn't turn on again.had car towed to dealer.it happened right before entering freeway, thank god.

My gas tank does not vent properly - the car has a detination problem and has exploded on four occations with a force that rocks the car.i don't want to get in it anymore, nor does my family.it has been in the shop for 25 days.

A boom noise has been coming fromfuel pump.vehicle has been in 7 times with no remedy found. Dealer said gas capwas expanding and collapsing.on 3-16-01gas cap/ fuel pump and fuel gauge were replaced. On 3-16-01 valveand fuel tank assembly were replaced; on3-23-01, dealer replacedfuel system cleaner kit, and fuel gauge assembly again, and 3-28-2001 gas cap andpressure relaease valve were replaced.

While making a right turn (in partivularly off a major highway) the car wilstall - no power, brakes, or power steering.numerous complaints have beent odealer and they have mmentionedthta this is a problem with thevehicle but cannot be fixed.please note that with the car stalling at such speeds, getting rear ended is inevitable in particular with trucks.

While traveling between 55-70mphand trying to pass another vehicle transmission would go into neutral position, pressing on accelerater would cause it to skip to 3rd gear, sometimes hitting gear downshift real hard, vehicle shakes, would hit neutral first before going into correct gear, had taken vehicle to dealer,vehiclewas test driven, and nothing found placed on diagnostic,no problem codes appeared. Transmission goes into neutral instead of third and goes into neutral when down shifting, this has almost caused a head on collision, consumer also states while going downhill, he shifted into third gear and vehicle went faster.

We have a five-year-old mitsubishi diamante. For the last week, my husband, scott has smelled a sweet smell in his car and had a problem with the windows fogging. Tuesday morning he started losing forward power when driving to work on i480.he noticed that his dashboard transmission lights were acting funny so he called our mitsubishi dealer.the service people asked if he had noticed that the windows were fogging or if he smelled any anti-freeze coming from the heater.scott was astonished that the sweet smell was antifreeze.the service advisor said that most likely it's because that diamante has experienced heater cores leaking into the passenger compartment and dripping onto the transmission computer.this is why he was losing power while driving on i480.one of my concerns is what health problems can come from driving in an enclosed environment while the heating system is mixing antifreeze fluid in the air that my husband is breathing while commuting to work. Later on that same tuesday, the service advisor called him and said that their service manager spoke directly with the regional mitsubishi service representative and he said that the heater core was too far out of warranty to be covered based on 36,000 mile warranty.the transmission computer, while covered up to 84,000 miles, would also not be covered because the failure was due to antifreeze dripping on the computer causing it to fail.

Vehicle check engine light came on and locked into third gear.noticed smell of coolant inside drivers compartment and hazing of the windshield.brought vehicle to dealer to have problem improperly diagnosed and had to have it re-tested two weeks later.heater core leakage has caused damage to the ecu and now both have to be replaced.total cost of repair for both was $3,357.62.coolant fumes are very toxic and cause a significant health risk and ecu failure could easily result in a very serious accident on the highway or elsewhere.the "fogging" of the windshield is a visibility hazard as well caused by the hot coolant in the defrost vents.

While driving abs light illuminated and the brakes failed.vehicle was towed to the dealer, who determined that the abs chip malfunctioned, and had to be replaced.

We have a 2000 mitsubishi diamante with 32k miles on it. Car is still under factory warranty along with an extended warranty we have purchased. After the first couple of thousand miles we noticed a "pulsing" feeling in the brakes as well as an intermittent abs warning light flash.we made the dealer aware of this so they replaced all 4 at approx. 11k.less than 10k after that we noticed the same problem and took it into a closer dealer to where we live, they replaced the brakes again. Now again about 10k the brakes are having the same problem. The vehicle abs light came on a couple of times and the car is ?pulsing? when applying the brakes and is worn out again.i spoke to mitsubishi customer service agent who is the dealer rep. Debbie krumboltz. She originally agreed to take care of the brakes after i met with her about the issue. When i made the appointment to have the repair done she denied agreeing to the repair? i in turn called mitsubishi motors and spoke to a person in the escalated compliant division named lisa, she would not give her last name and basically told me that the case is closed and mitsubishi is not going to do anything about it. I explained to her that this has been an on-going problem and the abs light is still an issue and that the brakes ate wearing out too fast and it is a safety issue. She did not care she again told me that there is nothing that they are going to do, she would not let me talk to a supervisor or anyone above her at mitsubishi and told me that that is the final answer and hung up on me twice. This is a safety issue. We feel that we are being ignored by mitsubishi and when i told them as a customer that had dropped 30+ thousand dollars on a car that is still under factory warranty to have this type of problem and a safety issue at that to be told ?case closed?? is the worst service and resolve i have ever experienced. Please help? thank you

The vehicle was experiencing problems with the brakes.the vehicle was taken tothe dealer who ignored the problem and denied service.*nlm

Ill be brief  i own the above car and have a safety problem that is not being fixed by mitsubishi.with about< tank of gas in the car, a hard right turn or exit off the expressways, causes the car to completely stall  no power steering, brakes, no acceleration. Worse, this is a problem with all diamantes (verbal via the service rep for the chicago area  jeff hampton).i have been in a situation more than once where this has almost produced a rear end accident by semi trucks and other vehicles.mitsubishi says this is an engineering issue and they dont know what to do (note this has been going on since july 2000), since a new tank or fuel pump would not fix the problem. Even the 2002s are going to have this problem.

I purchased the car used from a mitsubishi dealer, a month or so later i noticed a maple syrup type smell. The proceeding months the problem got worse and noticed that my windshield kept fogging up. I took it to my local repair guy who gave me an estimate of one thousand dollars to replace the heater core and informed me that if i dont i could have a computer failure because it is right under the heater core which in turn may cause an accident due to loss of control. My passenger side carpet is now soaked with coolant and the smell is horrible coming from the vents. I have heard that the coolant is toxic and can cause problems in your respiratory system which concerns me even more.

Tires extremely noisy since about 2,000 miles. Tires severely cupped after 5/6,000 miles. Ride extremely loud, with great deal of vibration. Since about 12,000 miles, extreme cupping of all four tires plainly visible. Tires at all times at mitshubishi recommended pressure, and rotated every 5,000 miles. No impact damage to any tire, or rim. No scuffing of sidewalls, or punctures. Tires apparently cupped from the start. Car purchased new, with 3 miles. Dealer cannot explain cause for severe cupping, but refuses to replace tires. Also contacted mitsubishi motor, who tells me that they have had some complaints on these tires. No one seems to want to accept responsibility. Concerned that tires may suddenly fail, es they are severely cupped (all 4) and ride with great deal of noise and vibration. Dealer claims problem not with auto, since properly aligned. Tires are balanced, and at proper inflation. Now becoming concerned for safety, and upset that dealer and mitsubishi doing nothing to correct condition. (dot number: tox82jm250tiresize: p215/60r16)

When i first start the car, drive about a half block, obtain desired speed, take my foot off the accelerator, and then when the car slows down, i press down on the accelerator, nothing happens. So i press down further on the gas pedal, and suddenly the car lurches forward out of control. So then i have to immediately take my foot off the gas pedal and brake slightly until the car goes the right speed. This has happened only when the car was cold and only intermittently, about seven times in the last 10 years. My mechanic supposedly fixed it, but the accelerator got stuck again after the alleged repair. There were no consequences except for a nagging fear in the back of my mind for the last 10 years.another intermittent problem is that the lights for tcl and fix engine soon will come on while i am driving, go off when i turn off the car, and then stay off for several car trips and one or the other light will come on again intermittently.

2000 mitsubishi diamante.consumer states vehicle surged forward.*tgwthe consumer stated when leaving a parking lot and attempting to pull into traffic, the vehicle barely moved at 5 mph, even though he was pressing on the accelerator and the rpm was not moving.after going about 1/4 of a mile, all of a sudden the vehicle jumped into gear and the vehicle lurched forward. The next day, a representative from mitsubishi went to the consumer's workplace and examined the vehicle. The representative stated the throttle cable needed to be adjusted and suggested the consumer take the vehicle to the dealer. The consumer stated the dealer never received any information to order a new cable and the his vehicle still has not been fixed.

2000 diamante malfunction, especially in cold or wet weather gas pedal sticks, requires additional pressure to overcome. The dealer was unable to duplicate the problem. *sc

My wife and i noticed antifreeze odor coming in through vents.when our windows would fog, our defroster wouldn't work.then our passenger side floor was soaked with antifreeze.we took the car to the dealer, our heater core was leaking.cost was $1300 to repair. Mitsubishi should be held responsible!!too many complaints.

Consumer stated can smell and see the vapors of antifreeze coming from vents of vehicle when vents are turned off. Took to dealer and dealer indicates was tsb on the faulty heater gaskets on vehicle.

About two months after buying a 2000 diamante; in oct, 2004,i started to notice thick fog on the windsheild that wouldn't go away by using the de-fogger and when using the heater, i would also notice strong smell on anit-freeze comming out from the vent. Upon inspection, the dealership described the problem as faulty o-ring in the heater core. The fix was costly, around $1100.00 however the car has been problem free since then.

The heating system on this vehicle has failed repeatedly on this vehicle.ususally this is only a minor inconvenience.there have been two instances where it was dangerous.once was in a heavy rain, where the defroster failed, the other was just recently in a rain/snow mix.the interior of the windshield completely fogs up making vision to the road and oncoming traffic very poor.i have had a "chip" replaced twice under warranty and will try again.

Front windshield fogs up, strong smell of anti-freeze, can't clear the fog with defogger, read potential risks to health because of the contact to anti-freeze fumes.

While drivingcoolant was leaking on passenger side. Dealership serviced vehicle and determined heater core needed to be replaced.

An anti freeze and smoke odor was coming into the cabin of the vehicle through the air vents.dealership indicated this was caused by a problem with the heater core gasket, and needed to be replaced.the entire dashboard has to be taken apart to replace the part.this was a common problem with these vehicles.*sc

For several weeks it was becoming increasingly difficult for me to clear the windshield on my car and i attributed it to hot, humid weather.coming back on the freeway one evening it suddenly became much worse and my husband and i tried many different combinations of cool/warm/fresh air to be able to see out of the window, but it never fully cleared.it was dangerous to drive under those conditions, but we made it home.there was a whitish film beginning to form on the window, visible in daylight.what was in the fumes that formed the film i am afraid to imagine.several days later as i was driving my son to school we both noticed a white, cloudy smoke coming from the vents directly in front of us.we kept the windows down to avoid breathing in the fumes.the next day i took my car to the dealership and was told the gaskets adjacent to the heater core had failed.it cost $5.10 for the replacement part, but the repair cost total $560.00 because they had to remove the entire dash to replace the o-rings.my car was in the shop for a full day.i'm also concerned because i've since learned that the anti-freeze leaking from the "worn-out" rings dripped down onto my car's computer.what potential damage could have occurred to the computer, is it ok now, and could it have caused a major accident if the computer failed.

Vehicle check engine light came on and locked into third gear.noticed smell of coolant inside drivers compartment and hazing of the windshield.brought vehicle to dealer to have problem improperly diagnosed and had to have it re-tested two weeks later.heater core leakage has caused damage to the ecu and now both have to be replaced.total cost of repair for both was $3,357.62.coolant fumes are very toxic and cause a significant health risk and ecu failure could easily result in a very serious accident on the highway or elsewhere.the "fogging" of the windshield is a visibility hazard as well caused by the hot coolant in the defrost vents.

Windows fog constantly and i can not get them defrosted.smoke and smell of antifreeze comes into cabin of car.took to dealer a year ago and was told nothing was wrong, car now has 98,000 miles and they are telling me it will cost 672.00 to replace the heater core.i have found several complaints about the same issues.i became ill in january of this year, the doctors (4 of them and three hospitals, ct scans, etc) could not figure out what it was.turns out it was breathing the fumes in my car.at that time, the smoke only appeared a couple of times, but now it has increased considerably.i think it's sad that mitsubishi will not repair this problem, nor have they corrected it.

Heating core is leaking antifreeze onto other components under the dash; strong smell of antifreeze within the car; windows fog up upon using any of the ventilation systems.

Dealer replaced the heater core at 37,000 miles, and at 80,000 miles the heather core failed again.consumer found two technical service bulletins pertaining to this problem. In both incidents, the windshield became foggy on the inside and the defrost fail to clear it. Mechanic stated the o-ring failed. When this occurred, antifreeze leaked into the engine parts. The anti freeze got heated and evaporated. It then seeks through the vents onto the windshield. Consumer noted this posed two safety hazards. Repairing dealer stated they alone has seen this problem several times.*ph*nlm

I currently have what is described to be a "heater core failure" in my 2000 mitsubishi diamante. I have been made aware that this issue is fairly common amongst diamantes. Any time i turn on the heater, my automobile is filled with a noxious odor that i'm lead to believe might be detrimental to my health. I am also unable to defrost my windows because of this problem. This causes a dangerous driving condition as i'm forced to constantly wipe the windshield with a paper towel.

Sudden heater core gasket leak, instantaneous fogging of all windows, causing a severe driving hazard, especially when it happens at highway speeds.

Windows were not clearing properly and smell of anti-freeze was very strong. Upon calling the mitsubishi dealer, i was told, it's probably the heater core. I ask if this is normal for a car less than three years olds with approximately 40,000 miles. The service manager told me, well to give you and idea, i just replaced one last week. I was told vehicle is out of warranty, cost to repair $650.

Nar 02/10/2003. The consumer had a new heater core installed in the vehicle. The consumer believed there was a defect because the vehicle was only 3 years old.

I purchased the car used from a mitsubishi dealer, a month or so later i noticed a maple syrup type smell. The proceeding months the problem got worse and noticed that my windshield kept fogging up. I took it to my local repair guy who gave me an estimate of one thousand dollars to replace the heater core and informed me that if i dont i could have a computer failure because it is right under the heater core which in turn may cause an accident due to loss of control. My passenger side carpet is now soaked with coolant and the smell is horrible coming from the vents. I have heard that the coolant is toxic and can cause problems in your respiratory system which concerns me even more.

Heater core on 2000 mitshubishi diamante failed andfogged up my windsheild. While driving home the night of the failure, a deer jump in front of my car and caused 4 grand in damage. I had to pay for the heater core at the dealership.

The windows kept fogging up, defroster was did not clear it up, 0 visibility, when defroster was on there was a strong smell of antifreeze. When car was driven for more then 30 min once shut of smoke was coming out of the dash board vent by windshield.

The heater core has failed for the second time. I purchased the car from a dealer with 54,000 miles on it and after 500 miles the heatercore is fried. The worst part is that when i went to the mitsubishi dealership to get my remote reprogrammed i got the printout of all the previous service that was done on it. The heater core was already replaced at 24,000 miles!!! does this mean that i will have to spend around $1,000 every 25k miles that i drive the car??? mitsubishi, please address this problem! regarding to the problem itself... I got all the usual symptoms - the windshield was fogging up, there was a strong smell of the antifreeze in the car and now there's a pool of antifreeze by the passenger's seat. This cannot be good for my respiratory system... Antifreeze is a poison. I've had some problems with my lungs before and if it gets worse after this problem, mitsubishi will look at a huge lawsuit.

The heater core failed and leaked on the floor board. The consumer would smell chemical fumes. The mechanic repaired the problem twice, but the consumer is still having the same problem. Please provide more information.

For over 2 yearsnow i have had problems with an odor in my 2000 diamanti and the defogger never seemed to work on the windows.a couple of weeks ago i saw something leak onto the passenger side rug but didn't' t guess that this could have something to do with the heater core.upon taking it to my dealer i was told this was hole in the heater core that had to be fixed immediately because it was dangerous and hazardous to my health to breath the fumes that were coming out of the core.the cost would be approximately $1200.i noticed i often had headaches when i drove long distances but was very concerned when my grandchild became very car sick (which had never happened before) upon riding in my car.i still didn't associate the heater with our problems.i think this is very dangerous and something should be recalled on these.i resent that after only 40,000 miles i must spend $1200 on something that is obviously a mistake on mitsubishi's part since it is not a wear factor.

Windows fogging up, heater not working, anti-freeze leaking into the passenger side floorboard.

Strong antifreeze smell and vapors coming through the vents. Especially when the heater is turned on. Windows are fogging constantly. The car started overheating and have to refill antifreeze. Service center said antifreeze is leaking and evaporatingand they heard about this problem before.

Noticed faint smell of anti freeze in oct 2003. Had problems with defroster clearing windows, very hard to clean. Noticed passanger side floor carpet is soaked with anti freeze. Obviously a problem with the heater core or the hose(s) which connect to it are leaking. Car has 60000 miles, and is well maintained.this heater core leaks directly over computers which, as far as i know, control the engine - and could cause it to act unpredictably or cut out altogether when driving. Heater core gasket was the problem according to dealer and i have had it fixed.

The heating system on this vehicle has failed repeatedly on this vehicle.ususally this is only a minor inconvenience.there have been two instances where it was dangerous.once was in a heavy rain, where the defroster failed, the other was just recently in a rain/snow mix.the interior of the windshield completely fogs up making vision to the road and oncoming traffic very poor.i have had a "chip" replaced twice under warranty and will try again.

All four passenger door windows are distorted. This impairs driver's vision, and makes things look likewrinkled.

The windshield wiper completely failed while driving in the rain.according to the dealer engineer who inspected the unit, the wiper motor failure occured and the motor must be replaced.the compelte failure of the wiper was very dangeours while driving in the rain.a question needs to be raised if there is any fundamental defect in the wiper motor; it shouldn't fail only after driving 2000 miles.
