Brake assist, traction control, stablitrack, and ABS lights continually coming on. When breaking while making a turn the breaks slip or give and then suddenly grab hold causing a grinding sound. Car wobbles while these lights are on causing a noticeable change in stability and control.

When driving the ABS light illuminates, w/accompanying message: "service stabiltrak" followed by 'service traction control". Car grinds when turning left. Today the gas pedal felt like it was pushing back when pressed then it felt like it locked up for a second.

When taking left turns the car makes a loud grind noise then the stability controll will turn on. Now the check engine light and stability controll light popped on while driving while also having engine power reduced which then applied my brakes causing me to almost go off the road.

I hear a horrible grind when making a left hand turn after a stop, car also felt like it did not want to go forward causing hesitation in left hand turn - very dangerous with oncoming traffic. Have had it to mechanic many times, either they couldnt find the problem or would fix this or that and then problems right back within days if not hours. Occasionally get service stabilitrac and/or ABS lights, usually lights would clear by next day when I took to mechanic and again they'd either find no problem or try a fix -still a problem. I believe they're going to try to replace wheel bearing next but from all forums I've read this doesn't seem to help people either, problem comes right back, recently rack and pinion had to be replaced costing $700 to fix, within 2 days I heard the grind, had hesitation on a left hand turn, noticed fluid under my vehicle upon return home, hoped it was A/C condensation, within days the power steering is going out again - turns out new rack and pinion is leaking and car is completely out if power steering fluid again after 2 weeks. I can't help but wonder if the sound and grind isn't what's causing my rack and pinion issues as well? Have owned 2 years now with this problem continuously throughout ownership of the vehicle. Approx. 68k miles on it when purchased now almost 90k have to be very cautious making left hand turns that there is no oncoming traffic as hesitation may cause you to get hit if vehicle can't turn in time. Have to completely let off gas and try again sometimes still grinds if so repeat is all you can do. Becoming very scary and costly with no fix found so far!!! Please investigate! Multiple posts regarding same issue some on newer models, very much a safety issue I can't even teach my child to drive in the car as I am afraid for their safety in it, as well as my own safety ever time I try to make a left hand turn.

I continue to have problems with my front left hub after replacing. I have replaced the wiring harness as well. Wondered if there are service bulletins with this same issue. While driving the car it makes a horrible grinding noise described to me as the hub adjusting the speed of one tire to match the other. It also flashes brake assist and stabilitrack issues as well as anti lock alert. This happens mostly turning left but most recently even while driving straight down the road.

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.

After I purchased this vehicle this summer I noticed that the engine wouldn't accelerate when pulling out in front of traffic plus I had to really press hard on the gas pedal to get power on small inclines. Took it to a dealership and of course they couldn't find anything wrong with it. It seems that if the engine light isn't on they don't have a clue. So I took the mechanic for a little drive and he still couldn't feel anything wrong or hear the slight squeak in the gas pedal but finally told me about the sensors in the pedal and that he would lube it. After he lubed the accelerator the vehicle ran great for awhile and now it is starting again and the gas pedals squeak is more noticeable when depressing it. The thing is my full warranty has now expired and I doubt that chevy would cover any costs. Another thing is the headrests in the back seat are way too big. You practically have to dislocate your shoulder to see out the back window when backing up; this is a real safety issue for vision. They need to have a recall to replace the whole bench and get rid of these high headrests!

Driving downhill a truck pulling a trailer brake suddenly in front of me causing me to have to brake hard. The brake pedal shuddered and felt like I needed to take my foot off the brake but I couldn't! Additionally the steering wheel shuddered horribly side to side. Braking on the remainder of the hill and for a while after had the same chattering, shaking, shuddering, and sort of brake grinding feeling making me feel like I could not rely on the brakes and maybe the steering was having problems too. Scared me and felt terribly unsafe!!!! This happened once before about a year ago with this car in a similar downhill sudden braking situation. I drive to avoid having to brake suddenly but sometimes it is unavoidable and I don't want to drive this car anymore because it feels too unsafe.
