I was driving and my cars engine light came on 1st then the traction control light. When they came on it reduced power to my engine and quit on the interstate. I had looked up possible causes when I had a test ran it was showing throttle body I replaced it and it never fixed it upon research I have seen multiple people who owns Impala from the years 2009 and up having the same issues and feel it is something that needs to be looked into. What I have found idk yet I am waiting on the piece to see if this is the issue or not is the pedal sensor could be the cause. But I feel it can be unsafe because my car had quit on a busy interstate with cars traveling at the speed of 65mph and higher. Just when I was looking it up I had saw so many other people having the same issues with their Impala. Please look into it thank you.\

It doesn't matter if the car is running or not the actuators to the air conditioner and heating unit start clicking and making a loud noise. After a few minutes it will stop. I went and had it checked by the dealership and was told it would cost between 500 and 600 dollars to fix. In any event I have talked to several people who own Impala and they have had the same problem. My sister was one of those people. She had to take her car back twice before it was repaired correctly. Apparently the computer chip in these cars are defective. The clicking noise happens even when the car is sitting in the garage and it is storming outside. I feel this is a manufacturing problem and General Motors should take care of the problem without any out of pocket money from the consumer. After all the taxpayers did bail you out.

On this day came out of work, started my car and started hearing a knocking, ticking noise coming from what appeared as the passenger side dash. I have yet to get it checked out but looking on the internet others describe it as the actuator. There were so many other Impala owners that experience the same, so I came on this site just knowing it would be some sort of recall but didn't find one. It amazes me that so many Impala owners have the same complaint and GM isn't fixing/ looking into the issue.

The contact owns a 2010 Chevrolet Impala. The contact stated that while driving at various speeds, the vehicle stalled. The contact stated that the check engine, engine power reduced, service stabilitrak, traction control, and the engine overheated warning lights illuminated. The vehicle was taken to a dealer where it was diagnosed that the secondary air injection valve, the secondary air pump, and the app sensor fault needed to be replaced. The vehicle was repaired but the failure was not rectified. The manufacturer was notified of the failure. The approximate failure mileage was 44,000 and the current mileage was 80,000....updated 07/15/14

I had purchased a 2010 Chevrolet Impala in July, 2010. The first attempt at repair of the front end vibration was on 10/22/2010. The dealership did not recognize the vibration. The vehicle tires were rotated on 01/26/11 in an attempt to stop the vibration in the front end. The vehicle was taken in on 03/18/11 for front end noise (thump) while turning the wheels. The vehicle was taken in on 07/07/11 for the thumping noise in the front end while turning the wheels. The vehicle was taken in on 07/28/11 for a front end thumping noise when turning the wheels. The vehicle was taken in on 08/16/11 for a front end thumping noise and the dealership notices the tires were wearing slightly cupped on the inside edge. The vehicle was taken in on 09/08/11 for a whining noise from the engine bay and power steering fluid was flushed. The vehicle was taken in on 04/09/12 for front end thumping noise, wheel bearing, transmission surge, and whine noise from radio. The vehicle was taken in on 06/27/12 for rough idle, tire replacement, transmission. The vehicle was taken in on 07/27/12 for rough idle, transmission surge, thump noise in front end and whine noise in radio. The vehicle was taken in on 10/05/12 for transmission surge, rough idle, thump noise in front end, and whine noise in radio. The outcome at this point is the dealership tried to reprogram the vehicle, GM approved replacement of all four tires, a replacement of the power steering pump, wheel bearing on driver front side. The dealerships have done two throttle body cleanings. The dealership has stated they will replace the rotors but GM would not approve replacement only turning on the rotors. This case has been opened with the better business bureau whom advised me to contact NHTSA. GM refuses to replace parts because their computer system cannot tell them what is wrong with the vehicle. GM has recalled the police vehicles for front end suspension and has a lawsuit pending in Michigan for personal vehicle.
