- Alton, IL, USA

Anytime I go to accelerate after coming to a complete stop at a stop sign, red light, or etc the car hesitates and then jerks forward. The car hesitates and loses power. While driving down a busy city road the car turned off. I had to try and steer the vehicle to the side of the road. The steering wheel would barely turn.

Why is there not a recall on stability traction control? I see thousands of complaints on the internet for GM vehicles. It seems to me that GM just doesn't care enough after the sale. I just bought 2011 Impala and now the stabalitrack service light keeps coming on while going down the road. It will do this for no apparent reason but happens mostly when accelerating. Using the cruise control on level road and dash warning light comes on and throws car out of cruise, decelerating while gages flip around all over the place. Power loss and lack of acceleration are definitely safety issues. Pulling out of my driveway onto Michigan highway and I get halfway across highway and car stops. This highway is 55 mpg and while I would have had plenty of time to cross the lane, car looses all power. Looking on the internet gives no help for a fix. I turned the stability traction control off, but the problem does not go away. I see on the internet that many people have taken there vehicle to the dealer garage only to get charged exorbitant prices for "possible" that do not seem to help. GM should get this figured out and not let every dealer garage do their own guessing on what will fix this very dangerous problem that is not limited to single model or year but spans many years with many models. My first vehicle was a GM but this may be my last GM. I would like to give a date below but this has been happening since I bought the vehicle about a month ago and getting steadily worse. I have had it checked out but nobody can give me any useful answers

Elay switch on driver side for air conditioner clicks for several minutes and blows hot air. The passenger side currently blows cold but now the clicking has been happening there also. This is obviously a common defect in Chevrolet Impala that should be taken care of. This happens everywhere all the time moving and parked

Traveling a state highway at the legal speed of 70 mph, had to break very hard. As the car slowed down the engine shut off and power steering failed.

On my way to work, I was making a next turn at a light when my car all of a sudden shut off and then turned back on twice in a matter of 15 seconds. This is very dangerous, if it wasn't for the very attentive drivers, I could've been rammed!!! the second incident was after I got off of work. My car was in a parking garage when this happened. I tried starting my car and it wouldn't start. I tried a second time and it started but the engine was revving really hard, like I was about to speed off or something. I turned the car off again and started it again for the third time and "service stabilitrak, service traction control, and reduced engine power" all come up on the service screen. After reading multiple forums online with hundreds of complaints about this. I was scared to drive home. I drove at about 40 mph all the way home (my job is a 25-30 min commute) and fortunately I didn't get stranded and my car didn't turn off in the middle of driving like some folk have experienced. GM needs to address this problem. Why isnt there a recall yet?!

While driving the traction control, stabilizer, engine power warning all come on and the check engine light comes on and sometimes the engine turns off. Pull off road, will not start then minutes later it starts. Check engine light stays on. After multiple starts the check engine light goes out. I have read multiple complaints about this, yet the nothing is being done. To repair this problem. The effects of this is the same as the ignition turning off. Pending on traffic. This could be deadly. This has happened alot.

I begin noticing issues when taking off from a complete stop where the vehicle would lunge forward like it couldn't shift into first gear. I had that checked and nothing showed as an issue, so the mechanic said it had to be electrical. This weekend I am driving it and after 25 minutes in the car the check engine light comes on, as does the notice that my engine power has been reduced, and to service the stability traction control system. I was coming to a stop light when it came on and I pulled off to turn off the car and restart it as that would work when it failed before to reset the system. It didn't reset and I had to drive it with reduced power the rest of the way to my destination. I had this fixed a couple years ago. I did get a notice from GM about the issue and the ability to be reimbursed or getting it fixed if there was a current issue and I was able to get reimbursed for it. Now it is happening again, but my mileage is too high to get it fixed under this repair notice because the letter says that the mileage coverage is only up to 120,000. If this is a known issue and I have already dealt with it before, why should I have to pay for it to continually fail when it has nothing to do with normal wear and tear, which I would have no issue fixing as a part of maintaining the vehicle?! this should be something that GM would fix every time it goes out because it is clear the issue is a malfunction of the overall system and not linked to anything that the driver does or doesn't do to maintain the vehicle properly. In addition what if it has to be replaced multiple times as is the case with mine. I have always been a devoted GM customer, but honestly I am not sure I will ever buy another GM after this issue. It is unsafe and provides anxiety when driving, because it might fail at the worst time and could need fixed again even if I fix it this time.

Rear defroster not working. Discovered burned-up connector in a plug under passenger footwell fuse box. Internet research indicates this is a common problem affecting Impala and other models over several years. This would therefore appear to be a design defect. Outcomes include reduced visibility due to inability to defrost/demist rear window and fire hazard due to overheated connector

My son while driving highway speeds 60-70mph, the car display would say "reduced power" followed by "service stabillatrac", "service traction control". shutting car down at highway speeds. Shut car off for 5-10 minutes and would B fine for a week, a month, six months!!! this has been going on intermittently for over a year!! car not under warranty and cannot afford to take to dealer every time it happens, needless to say no one drives it but me. Have not taking to dealer because research online and nothing seems to be a sure fix!! other people are replacing throttlebody, S, gas pedals, gas caps, ABS sensors, various wiring harnesses, batteries, grounds, computers without any of them being a sure fix. Someone will or may have already been killed by this malfunction and unfortunately did not live to say the car did this!!!! I know from reading online forums and the such that this seems to be a very common occurance on multiple years of this model!! all of this on top of a $2 key switch fix that took how many to die before anything was done!!!

We own both a 2011 and a 2013 Chevy Impala. Both vehicles grind and hesitate. They both act this way while taking off from a light, backing out of the driveway and then putting it in drive and any other time it feels necessary to do so. Except while being checked by the mechanic. We owned a 2007 Impala that did the same thing. Our remedy, push the traction control button to the "off" position. Stopped making the noise and no longer hesitates after putting it in drive. Of course, we have to do this each and every time we get in the car. No more buying Chevy's for us.
