My 2011 Impala is reading "service throttle. Reduce engine power" and then proceeds to shut down. Even after replacing accelerator pedal position sensor, vehicle is still reading same errors. This is very dangerous because there is no limitations to when the vehicle shuts off. After extensive research, a lot of people are having the exact same issue and Chevrolet hasn't attempted to do anything about it. Please help!
The contact owns a 2011 Chevrolet Impala. The contact stated that while driving approximately 65 mph all the warning lights illuminated and indicated that the engine was loosing power. The contact pulled over and waited a few minutes before restarting the vehicle. The vehicle was later taken to a dealer who diagnose that the app sensor and modulator failed and needed to be replaced. The vehicle was repaired for both components. Approximately 1 month later the contact was driving approximately 65 mph and the vehicle started to slow down while he was pressing on the accelerator pedal. After pulling over the vehicle was unable to accelerate but the RPM's were rising. The vehicle was towed to the dealer diagnosed that the transmission failed and needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 51,000 and the current mileage was approximately 52,000. The VIN was unavailable.
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.

I have a Chevy Impala, 2011, and a month or so after buying it the "service stabilitrak" light came on. Before I could get it into a shop, it went off. It came on again yesterday and my engine power all but shut down, I was trying to get through an intersection and thought I wouldn't make it. After researching, I see that Chevy has had numerous issues with this. Why are they not repairing the problem? this is a huge safety issue for drivers.
