Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

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.

While driving on the highway the "service traction control" message comes on, then, the messages "service stability trak" then "engine power is reduced". and then the car shuts down I had to quickly pull over on the side of the road. After a few minutes the car starts up and everything is fine. This happened twice since then. Every couple months the sensor lights would come on with the above message-without car shutting down. The lights come on a lot more often now-although the car does not shut down, it's the fear of the possibility. When googling this problem with the car it sounds like this is a common problem. I'm not sure why there hasn't been a recall. I'm bringing in my car tomorrow to get fixed. However, its upsetting that there seems to be a problem with the throttle position sensor, and there was a recall on a GMC truck in 2008 for this problem. This seems to be a problem regardless of year of miles of the Impala.

I was driving to a job interview on a barely moistened road. Service control then proceeded to pop up on my dash board along with the check engine light and reducing engine power. My car then shut off and I wasn't able to crank it for about 5 minutes.

I made an appointment with the Chevy dealer after receiving the recall notice. When we took the car in as instructed, we were told they did not have time. But they did have time to try to sell us some services from them. What is the companies responsibility to fix our car?

2011 Chevrolet Impala. Customer unsatisfied with GM response to fixing life safety issue. Consumer sent additional correspondence. The consumer stated the vehicle continues to have an engineering defect in the ignition switch, that could lead to the switch coming out of the run position. The consumer stated GM's fix was to modify the key and use smaller key rings. The consumer stated that was just a patch, that does not resolve the underlying engineering design manufacturing defect in the ignition. Status update 02/10/15 updated 06/22/15.
