When I got the car I new it needed new tires so I went to the tire shop fro.M the dealership but I ask the dealer if the car had been in an accident because I could feel it shimmy he was trying to sale me and 2009 but I could here its power steering pump was out they were both the same price it only made since to get the newer car. After putting new tires on I seen it needed oil change then and transmission needed serviced. While I was doing that I called to ask the guy if he was going to help me out. Lol yea bring it in all charge you twice as much as the place you are at right now so I let him know I would let all my friends know. It was one thing after another. Its been one thing after another then the flapper for the vent started flapping and makes an awful noise all the time there no working air conditioning so I took it to a mechanic to look at it needs brakes and rotters and the list goes on and on so I wanted to get out of the 29.9 interested the loan office contract me because im paying it off to fast and says I signed to wrong loan agreement and wants more money there in cahoots together it wouldnt let me mark everything thats wrong

We where coming home and heard a loud snap on my right side by the wheel and as we reduce speed the car starts to shake violently and the traction sensors went off the car reduced speed dangerously on the frw with traffic behind us and hard to steer... and moments after the car shut off.

When coming to a stop my ABS service stability traction control service brake lights all come on then my 2011 hesitation to stop when braking. Even if I go slow or just stopping at a stop sign. It pushes my foot from the brake. A cranking noise sound. I have gotten brake, tire rods, roaders and new tires. I don't know what else to do. This happens specifically when on the highway when having to come to a sudden stop. I almost crashed several times not being able to stop. Mind you my car only has 65000 miles on it. This is just too soon.

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.

My car has warn out two sets of tires on the rear. The still is showing. I have always known the front tires to ware out twice as fast as the rear. However, it is not happening with this Impala. For some reason the steel in the tires are always showing close to the middle of the tire. I don't drive much so this is a big problem for me. When it happened the first time with the tires that came on the car, I bought a new set and had the car aligned. It has done it again so I believe there is a defect in the car.

The contact owns a 2011 Chevrolet Impala. The contact stated that the wheels had seized in the front and the rear when, the vehicle was in motion. The contact had replaced all four tires but the failure continued. The vehicle was taken to a dealer where it was diagnosed that the front and rear alignment needed to be performed. In addition, the accelerator pedal failed to function properly and the dealer replaced the part. The contact was unable to determine when the vehicle would be repaired which was unreasonable for the contact. The failure mileage was not available.

My service air bag light stays on. I had it checked out. The passenger seat sensor is faulty or has faulty wiring. It's a newer vehicle, I currently have 72,000 miles on it. And is a safety concern for anybody especially my kids who rides in my passenger seat. The sensor will not acknowledge any weight on the seat and will not activate if I were to get into an accident. I called up a while back and put in a complaint. Somebody called me back but never answered my phone or messages I had left. I've researched this issue and have noticed there's a lot of people with the same problem. I expect Chevy to stand by their product and address this issue. Thank you

I was driving home from work and the car started acting like it was uneven. I got to where I could pull over and found a balloon growing out of the side of my tire. The car is not that old and the tires in my past Impala's have lasted much longer. I am not happy with this. I had to call someone to help me so that it didn't explode and cause more damage.
