2012 Chevrolet Impala: engine stalls while driving

Filed Sep 23, 2025 · Electrical, Engine · FL

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 owners who complain of the same exact problem. Yet Chevy has issued No recalls!? The only recall I've seen close to this is for 2011 year models. Although my car is a 2012, 2011 parts likely were used. If the recall affects 2011 Impalas, then any model that used 2011 parts should be included in this recall. I cannot trust the safety of my car's Traction Control System anymore as it comes on without warning, under no circumstances where it would need to come on. People are in danger with this defect! The car cosmetically, specifically the paint job and the flimsy actuators, are also defective. I've always taken excellent care of my vehicle, regularly having maintenance done at my local Chevy Dealership. Another defect that Chevy had to fix was my fuel pump that went out for no reason! I have receipt for this.

Since 2017, upon starting my car I get all of the following alert msgs "service stabilitrak", *service brake assist" and "service traction control" on my dashboard. I've had the car into les schwab and error code diagnostics done both before and after both front hub assemblies were replaced. The same service messages still continue to appear on the dash. Les schwab has checked the hub sensor wires repeatedly and all error codes and find them to be ok. They find the car to still have a crunching noise coming from the front end of the car, most markedly when turning the wheel to the left, but can also be heard when there is a drop in elevation, as when existing a parking lot into a slightly lower roadway. On june 14,2019, while the car was in motion and turning right at a stoplight, the same situation occurred as has when I make a left turn. The car suddenly acted as though the brakes were being applied very hard and then the car halted briefly with traffic behind me as though it would stall out. I applied the accelerator till I forced the car to move around the corner and after about a minute of fighting braking resistance, I was able to regain normal 40 MPH speed with the flow of traffic. This occurred on dry pavement with no precipitation. Outside temperature was around 100 degrees. Best driving conditions with no rough roadway. Les schwab said the problem with the hub sensor and left turning is a known problem to them and said they wish it would be made a recall item as it is a common problem now. I don't feel safe driving this chevy impala. Love my car but won't take a chance on purchasing same make and model. I wasn't so surprised when researching these issues on the internet to find huge number of owner's having the same problems.

Car has 68,000 miles. A few days ago the engine light came on, which disabled remote start. I didn't realize this until I went to get into the car. I'm in mi and this past week has been very cold. I jumped in and drove it to work (less than 3 miles). On the way, the traction light came on. No surprise, as it was a little slippery. No other problems. On way home from work: car starts up fine, no warning lights at all at start. Its about 13* out. Almost home: engine light comes on, traction light comes on, then right before turning on my road the stabilizer light comes on and reduce power light, car jerks and loses power like its going to stall out. It made it home. Next morning, engine light on but nothing else happens. I call around and dealership suggests I bring it in and hook it up to run a diagnostics for $98. I go over to parts store and have them run it first. Error codes show up that "don't really mean anything" and they reset the engine light. Runs a couple of days fine with no problems, lights coming on etc. Temp drops again and repeat the whole process all over. I bring to the dealership and they tell me it needs high pressure fuel pump and new lines, after they asked me if I ran e85 in it, which I do because that is what they suggested when I bought it! I can't afford the $900 right now and I picked it up. I called another dealership to get another estimate and I'm told that this is a common problem (we're seeing this all the time. It's a problem with running e85 in cold temps). That person suggests I run mao44 and prem unleaded in it and it should run fine for a while. I"m also told that this is not covered by the powertrain warranty and there has been no recall, even though "we're seeing this all the time".

When I back out of a parking stall or driveway and still have my foot on the brake and then I put it in drive, when I try to turn the wheel to start to drive down the street, it is like I lost power steering and it takes everything in my power with my hands to turn the steering wheel. It feels like the steering wheel locked up. Also when I am starting to pull into a parking stall when the car is barely moving the steering wheel seems to lock up with no power steering and I have difficulty turning the wheel. There are times when I can't get the wheel turned and I'm unable to park in the stall. While driving at normal speeds and when I go to turn, it doesn't matter whether it is turning left or right, the power steering is very stiff and sometimes will stiffen up to the point that I have a hard time turning the wheel. I took into the dealer in 12/2016 and asked them to check it out while they did an oil change to my car and they said all fluids were fine and nothing is wrong. I have come very close to having a wreck when I try to turn and the steering wheel all of a sudden stiffens up so tight that it takes all my strength and power to turn the wheel. It acts like the wheel isn't going to turn. This has been going on for a few months now. There is something definitely wrong with the steering. My 2012 impala only has 17,000 miles on it. I bought the car brand new and I'm afraid to drive it because of this steering issue and not being able to turn the steering wheel. There should be a recall with the 2012 impalas because of this issue. There is definitely a power steering or other issue that is causing the wheel to stiffin up so tight that you can barely turn it.

About 8 months ago my 2012 chevy impala started causing issues when the engine light appeared with the reduced engine light. Taking it to a dealership, they put the computer on it & were unable to determine what the codes were related too. I then searched google for any issues comparing to mine and found several complains about the same thing. Following the repairs that others have performed, I tried the same thing with no results. At the moment I am looking at replacing the throttle body sensor with the hopes that it will be fixed. The safety concerns is that my vehicle will be fine for a few minutes but then the reduced engine light appears and my car will continue at very little speeds and the shifting from gear to gear will go up to 5 amps. My car will then start bucking like a horse in the middle of traffic until it stabilizes and I'm able to run at good speeds. My car has not yet stalled but with it reducing speeds in the middle of traffic, it causes safety concerns as a fast moving car can come up me and hit me. I hope this gets attention from gm as I have read that several others that had the same issues. This is my second message for the same issues and I do not recall having received a response from my 1st complaint. Please advise why gm has not made a recall on this issue and give their customer's a better driving experience. Thank you.
