I have about 72,000 miles on my car and the service stabilitrak, service brake assist and service traction control messages come on and the ABS and electronic stability control light also are on. It happens when turning left or right and also the ABS kick in and effects the steering. I have replaced the right and left hub assemblies and it has not helped no codes are found when vehicle is scanned. This has been going on for several months. Thanks for your help. This will all happen in drive way and on city roads/highways.
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.
Abs/traction control failure. Both left and right wire harnesses had to be replaced ti to wire rubbing in frame and going to ground. Gm has four tsb's on this known problem. Abs/traction control or federally required safety features. This need to be a full recall.

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.

When driving after every attempt to make a left turn,my service traction control,service brake assist, & ABS light all pop on. Since then it has went on and off for many days until it just finally stayed on permanently. Also message: "stabilitrak service and traction control , brake assist " finally took it to a chevy dealership in culver city,ca in may 2013 & was told they tested the front ABS connector and traction and found nothing wrong and no code errors. Reset the sensors anyways and adjusted the timing. As soon as I drove out the dealer,same error messages and lights returned. Took car again to same dealer &wastold "I must have drove through water or oily surface and lights would go off after I drove 20 or so miles".lights & errors did not go away.returned to the same dealer again,this time again found no errors but they proceed to replace the tire sensors and reset the sensor id. Lights&codes went off for about a week then returned with a grinding noise when left turn, loose engine power &steering power, light &codes continue to stay on,& stalls for a few seconds when left turn. I have been at a light in the middle of making a turn when the car will stall & not let me take off.brakes appear to lock up.just missed a few car accidents due to stall. Has left me in dangerous situations as I have almost been hit head on & was hit from behind because I could not accelerate and got stuck on the turn. Cannot accelerate in a timely fashion is a huge problem. Because the dealer obviously could not resolve the issue had tire and brake expert shops look at the problem a few times. Also not finding the problem. Finally decided to just try &ignore it but after so many close calls of accidents& endagering my families life it is not acceptable for me to just deal with it anymore or to continue to spend money to try & find problem.forums prove others have the same problem.
I was driving down a hill on kalamazoost in lansing mich. My power steering and power brakes stopped working. I pulled on the steering wheel to turn the car into a hedge of bushed on the side of the road. It stopped before I hit them.

On june 28,2014 while driving down houston tx beltway. I was involved in an accident where my car hit a cement guard rail and brakes fail as well as no airbags deployed.
While driving my car highway speed was 65mph, at that rate of speed my vehicle was picking up speed and when I went to press on my brakes, it was if I was driving on ice and my car was skidding. Two days later I stopped for gas and my car wouldn't start, after my 3rd attempt, it stuttered hard time turning over. Once it did I turned it off but the car was still running. I did this several times. Very scared to drive my car back home because I'm out of town. My lights says I have low right tire pressure but I don't, it's back left tire for some odd reason.
I was driving and after making a left turn, my service traction control, service brake assist, and ABS light all popped on. It went on and off for many days as I would stop and then re-start the car.

Lights and codes went off for about two weeks then popped back on upon making a left turn. In addition to the lights and codes, the car now make a loud grinding noise and the car stalls. I have been at a light in the middle of making a turn when the car will stall and not let me take off- 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.

Same incident twice. I am driving either at low speeds (5 to 10 MPH) or at 30 MPH. The light service stabilitrak and brakes comes on. After I turn off the car, the warning lights and the message go off. I took car to dealership but they said they could not help because the warning message is off. I have seen messages across the internet posts that other impalas (2012) are doing the same thing.
Brakes have what I feel is excessive amount of fade especially after just a few stops seems to occur more at speeds over 50 MPH.
When stopped at a red light the peddle would slowly drift towards floor. The car began to roll as if the brakes were releasing. I applied more pressure to the pedal halting the vehicle. I took the car to a dealership and was told it was due to the location of the master cylinder and gm was aware of it. My concern is that this may cause loss of brakeing when in motion.
