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!.
While driving down the road, the car will violently jerk, and the dashboard will flash, reduced engine power. Now car won't move at all. We have replaced the gas pedal twice! Chevrolet needs to address this issue. I am seeing it all over the internet.
