I had three cars in front of me stopped. I did not see any breakl lights and I hit the car in front of me pushing the other cars to hit each other. My front end of my car was severely damaged bad enough to damage the radiator and destroy my ac unit. I'm not sure what else was damaged. It sent the person in front of me and myself to the emergency room. " my air bags did not deploy ". my vehicle was moving on a city street.

When stopped in traffic or at a stop light, my vehicle will idle roughly and sometime stall. It does this in drive, neutral and park. I've had it checked and they couldn't find anything wrong. There are no codes showing a problem.

Accelerating while entering a freeway, took foot off the gas and the vehicle continued to accelerate. Applied brake but vehicle continued to accelerate. Put vehicle in neutral to try and slow down and again applied brake. Vehicle began to spin to the right and we hit the guard rail, hitting the passenger rear bumper and the driver's side front bumper. Side air bags deployed. Car spun into the middle travel lane and began to spin around. Car was slowing down and was able to turn car off. Fortunately no other cars were involved. An off duty sheriff's deputy stopped and said he noticed smoke and thought the car was on fire but no fire occurred. When state police arrived they asked us to move the car to the break down lane. Was able to put car in reverse and backed car to breakdown lane. Tried to put car in drive but car wouldn't go forward.

The oil pressure gauge is reading above 80. Had oil changed immediately. Was told that there have been complaints regarding the mis reading of the instrument panel. Contacted GM and was told that at this time they are not covering the repairs and that it is the consumers responsibility to replace the engine sensor system. GM has some of the rudest and nastiest customer service representatives. I had to call 3 times in one day. They even hung up on me. I spoke with [xxx], [xxx] and [xxx]. I asked about the safety of the vehicle and other potential problems, such as engine fire or entire system shutting down and not responding. They had absolutely no answer for me other than they are not covering the cost of the repair. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

In March 2012 I had motor mounts installed on my 2005 GMC Envoy at the dealership jay GMC Buick columbus Georgia. On August 26,2013 they are telling me I need new motor mounts because of the age of vehicle and miles they need to be replace. I guess parts are old and professional installing is old to. During this same time had a tune-up {major} and now have to have coil and plug install. This make it seem paying for professional serve is a waste of time. My fuel injector also needs cleaning again. In the future I can only expect 40,000 miles on anything fixed by dealer.

I have been reading a lot and it seems to be a common problem in the 2005 series GMC Envoy, Chevy trailblazer. Basically the cooling fan clutch goes bad easily and quickly. When you start the engine it is fine but after the clutch needs to engage it either clicks, and doesn't engage or it just makes that common jet engine roaring. This is all to common and GM needs to do something about it. There have been people with 40,000 miles or 140,000. I my self am on my second one and it is already doing to the same thing after 5 months.
