2012 Chevrolet Impala Vehicle speed control Problems

“While driving home from work during rush hours my 2012 chevy Impala's dashboard lights up saying service traction control, service stabilink, engine power reduced terrified as I was in the middle lane trying to get over as my car began to go into limp mode.I almost got rear ended due to this problem. I was accelerating from being stopped.”

“I stopped at a intersection,and pulled out onto another road,the car backfired and quit running ,leaving me in the middle of the intersection,and almost got hit. I have taken car to dealer and they say the car is operating normal. This happens alot within this vehicle when accelerating.”

“Car experienced complete engine and electrical system failure while accelerating onto busy highway. There was no emergency lane, so brought car to a halt blocking one lane. This was as very dangerous situation. Later determined that the cause was a loose hot wire terminal connection to the fuse box. It had either vibrated loose or was not tightened adequately at time of manufacture. Local dealer was not interested in reporting this event to the GM data base, so gave me a Chevrolet customer service number to call, which I did.”

“Service stabilitrak - reduced engine power lights came on along with the engine light while driving on the highway causing the vehicle to not be able to accelerate to the appropriate speed.”

“When driving with the engine at lower than normal driving temperature, driver stops at a stop sign and with hard acceleration the engine surges from full power to dying out as tho fuel starved.this continues in a jerking action. Until; the driver removes his foot from the accelerator and then presses the gas feed again at which time the engine runs smoothly. This has happened on numerous occasions, however the dealership can find nothing wrong as the engine is now at normal running temp. Driver was told the problem is in the throttle body of the fuel system --- help..”
