2012 Chevrolet Impala electrical system problems

“I have about 08/1825 had the throttle body replaced on my vehicle which assisted with the problem temporarily. Then the problem started again 09/20/25 the car act like it’s stalling while driving and can’t see what hear the vehicle is in. The car is not getting any signal to the engine as I have been advised the TCM is faulty. There was a code of U0101.”

“The actuators in the air vents are faulty and I've had to have them repla ed multiple times now. They still continue to make clicking noise sounds and blow cold air in winter/hot air in summer. The trunk deck lid paint is bad. The clear coat has been coming off. Paint all over the car's clear coat has been coming off. There is also some spots where it's down to the metal showing rust/corrosion. Finally, and most seriously, is the car's Traction Control System. It goes off constantly and without warning! It's been doing this randomly, in all types of weather conditions, for some time now. It goes off under normal driving conditions. I barely pull out of a parking space, or make a slow turn, or pull out of a parking lot at a very slow speed and it just goes off. The really dangerous part is that it stalls the car almost to a complete stop, when I've been making a turn well before oncoming traffic, and it stalls almost causing an accident on several occasions now. Most of the incidents are on sunny days where there's no inclement weather! This system is not safe and is unreliable. I've checked many public forums, like Reddit, and there are many other Chevy Impala…”

“I put my car in reverse and the car turned off and have turn back on. When I try to start it, I don’t hear any fix or crank. Before this happened, my car was slow to change gear or it would will change so fast that my car will lose control and I did not feel safe at all.”

“The contact owns a 2012 Chevrolet Impala. The contact stated that on three separate occasions, while driving in the rain, the steering wheel seized. Additionally, upon starting the vehicle, the key failed to release from the ignition. The TPMS warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed and determined that the starter needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was contacted but no assistance was provided. The failure mileage was approximately 80,000. The VIN was not provided.”

“I have a 2012 impala that I have had since 2015 and a little while after I got it the engine light came on and it said it was the fuel pump control module requested Mil illumination and evaporated emissions systems leak detected (large leak) and at times the gas tank sparys back at up if you don't let it sit open for a little bit. I have had these issues fixed multiple times and by multiple mechanics who still can't figure out what's going on.”

“The contact owns a 2012 Chevrolet Impala. The contact stated that two days after purchasing the vehicle and driving at an undisclosed speed, he heard an abnormal clicking sound coming from the dashboard. There were no warning lights illuminated. The vehicle was taken to the dealer who diagnosed that the sounds were coming from the heater actuator and it could lead to an air conditioner failure. The contact stated that the vehicle was not repaired and the failure persisted. The manufacturer was made aware of the failure and informed the contact that assistance would not be provided since the vehicle was out of warranty. The approximate failure mileage was 100,000.”
