Stabilitrak, traction control issues

Asked by Jun 28, 2016 at 12:07 AM about the 2012 Chevrolet Impala LT

Question type: Maintenance & Repair

I have a 2012 Chevy Impala with about 130,000
miles on it. About a week ago whenever I make a
left turn the traction control light and abs light
would come on and then go back off. Now when I
make the left hand turn it tells me to service
stabilitrak,  service traction control and service
brake assist. I changed my brakes this morning
still no luck. Can somebody help me please
because I don't have all this money to be spending
out!

The system will have to be checked to find out how many sensors are setting codes, could be bad sensors, could be broken wiring or even a processor problem.

I think it is an indication of a bad wheel bearing assembly, (hub assy.) if you get the car scanned for codes it would tell you where the problem is. It is possible there is a bad wire at the wheel sensor like tennisshoes says.

I also have a 2012 Impala and have the same issue. I thought it was related to my battery which died and needed to be replaced, but the lights come back. I hear a noise and have hesitation when I turn the wheel to the left.

Sounds like you have a bad wheel bearing and if it is grinding then it is getting hot, so it fried the wheel sensor. Replacing the wheel bearing hub assembly has the new wheel speed sensor on it.

Same issue with my 2010 impala , bought used from a place that had 08-12 models . Every single one I test drove did the same hesitating vibration then shoots off , as well as the service stabilitrak abs on the dash on left turns only . Also noticing a grinding noise like a low power steering pump whine when turning the wheel left even slightly on straight roads and any speed . On occasions I also get a loud front end noise sounds almost like i hit something then the abs light would come on

Check your wheel bearings. If the ABS light is on getting the codes read saves a lot of time, the codes tell you what could be wrong, and which wheel to look at. Checking for a bad wheel bearing is a manual process, seeing if there is any play in the wheel at the bearing.

Always left front wheel. When stabilitrak warning light is on, gear indicator does not show which gear I am in and car will not accelerate. I HAVE had the car serviced. NO codes show up. Brakes and bearings are good. And this problem seems to be pervasive.....so many posts about it. One poster noted that it started after the ignition recall work was done and, though it may be coincidental, mine started after that, too, though this might just indicate a mileage correlation.

2011 Chevrolet Impala LTZ - Just had new inner and outer tire rods replaced, new brakes and an alignment. Still get ABS, service StabiliTrack, and service brake traction control indicator lights. Car is driving fine though. Where/How do I get the sensor codes checked.

You can get this done at an auto parts store. Make sure and ask if their scanner is capable of reading ABS codes. You want the ABS codes since that will tell you where the problem is and what to look for. Write down the codes.

Hey everyone I had the same problem with my 2013 Chevy impala what I did was just turn the traction button off and had no problem the only thing is that you have to control your car manual which mean if he rain or snow you have to really be able to control the wheel

My Impala does the same thing. Grinding with left turns, unless I remember to turn the traction control off. Is there a way to make the traction control stay off? Sometimes I get the service ABS/stabilitrack too.

I have a 2013 Chevy Impala with the same problems, 'service ABS/Stabilitrack, grinding noise, decreased power and car will nearly stop on you from time to time, particularly when turning. Taken to dealership, more than one, they GET NO CODES on diagnostic. It can't be fixed, except to turn off stabilitrack button and keep turning it off. Really needs to be a recall.

Also have a 2013 Chevy Impala with the same issues. My daughter is a manager at auto zone so knows several mechanics, one of them had my car up on a rack all day and checked everything that he could get his hands on and my car is in great condition. No codes come up.

my 2013 ltz impala does everything that i have been reading here. i replaced both front hub assemblies, all the pads and had the rotors turned. still, all the issues as before. it was so bad at one point, i could not get the system reset when all the warnings came on and the computer had control of the car. there has to be a way to totally disable the computer and leave the driving to us!

2014 Impala, started car and the car vibrated like it was idling very rough, once I put it in gear and moved the vibration quit. I turned off the car, restarted it and was ok but then the Stabilitrak Service needed message came on. Come on Chevy - do a recall!

reidman709 so now you need to check all the computer wiring looking for a broken wire, then if the wiring and grounds check good then it is either a BCM or ECM failure, in rare case I have seen both fail caused by a voltage problem.

Goodness at all of the time and money you people are spending on the wrong thing. Your ABS wiring harness has a short in it. When you turn the wheel you have a wire separating and it causes the warning light and the noise that you hear. You need to replace the ABS wheel speed sensor wiring harness. 40 dollars. This is such a known problem at Chevrolet that they keep both sides in stock.

I have the 2010, Impala with ABS and service stabilitrak lights on. After replacing the right Hub and Bearing assembly the same lights were illuminated and the code checker still pointed towards intermittent or no signal from the right front sensor. After tracing the wiring harness down to the point where the smaller plastic protector joins to the larger plastic protector (just beneath the alternator), there is a small gap (about 1 inch) between the large and smaller plastic protectors. In the gap the wires were unprotected except for some black tape wound around the area. I noticed the tape was worn and I removed the tape to expose the wires. One of the two wires (lighter colored one) in this instance had been rubbing up against the frame and wore through the insulation and only one small strand of wire was still intact. I cut and spliced the wire back together and all lights extinguished.

2012 Impala...get the Service Stabilitrak, Service Brake Assist, Service Traction control messages. Don't have the money to have it looked at and repaired. I just turn off the traction control everytime i start the car. Don't recall when it started...i think i may've been after i took the car for inspection. IRONIC. At that time, the mechanic said my tires barely passed. I have since had them replaced and still get the same messages.

I have a 2012 Impala with 69,000 miles on it that had the same problem. Took it to Chevy dealer and they replaced the "wiring harness connection to LF wheel speed sensor". It took care of the problem. They said it did not show any codes on their scanner when tested before replacement. It was still under my extended warranty so I only paid the deductible. Otherwise the cost would have been $353.15 This was at a dealership in Omaha. Hope this helps someone.
