The contact owns a 2011 Chevrolet Impala. The contact stated that while driving 35 mph the vehicle hesitated. The contact applied more pressure to the accelerator pedal and the vehicle stalled. The traction stabilizer warning light began to illuminate one week later. The vehicle was taken to a dealer for diagnosis and the contact was informed that the accelerator would need to be replaced. The manufacturer was notified but offered no assistance. The vehicle had not been repaired. The VIN was unavailable. The failure and current mileage was 53,000.

I was driving 60-70 miles per hour on the interstate and the engine began to lose power. After a couple of minutes the engine got a sudden boost of power. I was told it is the sensor on the gas pedal that is effecting the engine power and it is not covered by power 100,000 mile warranty.

After I purchased this vehicle this summer I noticed that the engine wouldn't accelerate when pulling out in front of traffic plus I had to really press hard on the gas pedal to get power on small inclines. Took it to a dealership and of course they couldn't find anything wrong with it. It seems that if the engine light isn't on they don't have a clue. So I took the mechanic for a little drive and he still couldn't feel anything wrong or hear the slight squeak in the gas pedal but finally told me about the sensors in the pedal and that he would lube it. After he lubed the accelerator the vehicle ran great for awhile and now it is starting again and the gas pedals squeak is more noticeable when depressing it. The thing is my full warranty has now expired and I doubt that Chevy would cover any costs. Another thing is the headrests in the back seat are way too big. You practically have to dislocate your shoulder to see out the back window when backing up; this is a real safety issue for vision. They need to have a recall to replace the whole bench and get rid of these high headrests!

Impala 6-cyl

I have 42,000 on my 2011 Chevy Impala and the service traction control and then reduce engine power as well as the check engine light came one. I have read it is the throttle body and not covered under the extended warranty, but numerous people are having the same problem with the same exact thing and no recall or any kind of care is coming from GM.... and those of us that are still paying for our cars are getting the short end of the stick...

My first issue was with the center head restraint in the back which totally blocks vision using the rear view mirror. I asked the dealer to remove it and I was told they could not. Backing up is impossible except with the side mirrors and traffic immediately behind is blocked when driving. This is a serious safety hazard. There have been many complaints but GM refuses to issue a recall to adjust these headrests. Also, I live in the tn mountains and the cruise control completely disengages when going downhill. The dealership told me "this was normal and all new cars did this to save gas"! I'm not that much of an idiot! cruise control is set to maintain speed.... period! please.... can you help?
