I just got a letter from Chevrolet yesterday about possible broken solder connection within the Accelerator Pedal Position (APP) sensor in my 2011 Impala. The letter did not say what other models may be covered.

It doesn't appear to be a full fledged recall but more of a service bulletin. The letter outlines the symptoms--DIC messages stating "Engine Power is Reduced", "Service Traction Control" or "Service Stabilitrak" and says not to take the car to the dealer unless it manifests those symptoms. Should the problem appear, GM will repair it up to 10 years from the date of original sale.

Not surprised, our terminals used in our electrical systems have no place in a car.

I got. 2010 Impala and I got the same letter. I actually have been having this problem on and off for the last 6 months. I m taking to the dealer now but i just went over 120k miles, I Hope they can still fix it.

took it to the dealership and GM refused to pay for it! 255 miles over.
Will never buy anything from GM ever again.
