- Audubon Park, KY, USA

The car has been in the shop twice within 6 months having it. It was towed twice, once for transmission issues and having no power to it at all then it back in the shop for warning lights. I also had it in the shop for about an hour to have a new tire put on it after loosing air. It had to be towed back home for all the brakes being shot and I'm now having an issue with the rear left caliper having a slow leak, the rear left sway bar is also broken in half. The whole entire car has issues and the leasing company and dealership refuse to do anything to help along with not helping me get the payment down. After one thing gets fixed, another thing happens. The suspension is getting bad and has been like that since my fiance and i got the car. The dealership said everything was new and fixed. We had 2 kids in the car and their safety was put at risk as well as others that got in the car. The car is getting to be a death trap for me. the warning lights that were coming on were Service Stabilitrak, Service Brake Assist, Service Trac Control and Service Brake System. These were coming on after I had the car in the shop for the transmission issue. Those lights are now not coming on. My fiance and I were told by the dealership that the brakes were new, nothing mechanically wrong with the car and drives smoothly, this was said before we took the car for a test drive. We were there to buy a car but after we signed the papers, we were told it was a lease.

Clunking, grinding noise service stabilitrak, service ABS lights come on lose power when reversing or making a left turn. After much research there seems to be a problem with the wiring harness going to the sensors in the wheels. Many people are having this very same problem across many years of this vehicle. People are spending money unnecessarily on parts such as wheel hubs and bearings without fixing said problem. Many people are also reporting cars turning off as a result of this.

The electronic stability control system is constantly on even when my car is stationary my antilock brake system light is also always on. Some times I lose power when I start to drive. I had it checked and had the sensor replaced, but the problems were not solved.

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.

Service stabilitrak came on when merging on to the freeway, (which involved a turn to get on the on-ramp, ) shutting down the car completely. Almost hit by a semi. I have had the bearings replaced because of stabilitrak light. How has this not been recalled" my friend and I almost died because of the faulty sensors or whatever it is with these crap bearings. I was told how the bearings are made with the sensors being placed in a completely ridiculous spot by auto parts stores. Saw plenty of complaints online with this vehicle. Same issue. How has nothing been done with this"

I was going slow (20 mph or less), expecting to stop with my foot on the break. A car slammed in back of me. On impact, I pushed the break all the way down to the floor, without any resistance. Just prior to that, the breaks were slowing-down the car as expected. My car slammed into the car in front of me. There were no break marks on the highway as one would expect if the breaks were working. The breaks simply failed. After releasing the breaks, shouting off the engine and later starting it up, the breaks are currently working as before the accident.

My car is trying to kill me. At a complete stop when I hit the gas the traction control comes on. My dash says service stabilitrak, traction control and ABS. I must turn off the traction control to drive my vehicle. With all that, if I drive up hill it turns the traction control on, the ABS and traction control light up and the lights stay on. When the car is restarted all the lights go away. Twice I was pulling onto the highway from a stop. That situation happened and my car didnt move. Luckily the car was able to move or else I would have severly injured. This happens with my vehicle daily. I took my car in because my alternator failed. I told the dealership about a tsb for the issue and they did nothing. It also happens a lot if im accelerating while turning a corner. The dash lights up like christmas lights.

When I start driving on local street each morning, I make a left turn, the car makes a loud grinding noise and my service traction control, service brake assist, & ABS light all come on. They also go on & off when I go over speed bumps make a loud grinding noise. The traction control symbol will come on and I will be stuck trying to accelerate. This is very dangerous as I have almost been hit from behind a few times due to not being able to accelerate in a timely fashion. I have gone on Chevy Impala forums looking for other drivers who may have experienced this are there are a good number of them. It seems to be an electrical problem. I finally took it to a mechanic and they could not reproduce the problem. It still happens.
