Stabiltrak abs traction control warning lights all come on vehicle shudders and power is reduced. Researched and found 100's of reports of the same issue with the Impala and similar complaints in the light truck and SUV models. Fix is relatively inexpensive if your mechanically / electrically inclined as involves splicing in a new wire harness for the abs sensor. Said harness is about $20 it shorts out due to insufficient gauge of wire used on original factory install. Replace harness has much sturdier gauge from what my research says. Repair shop quoted $700 to repair glad I told them to put it back together. They have a fleet of Impalas as loaners so they know they are gouging people when they say replace wheel hub assembly abs sensor and wiring harness when they know it's the abs sensor period. Chevy needs to do a recall. Issue happens when car is in motion after turning or going over a bump wiring that has been wore thru due to placement of wiring in a high friction area, wire wears through coating exposes wiring that shorts out and sends codes to computer concerning abs stabiltrak and traction assist causes vehicle to behave erratically others have reported caused vehicle to stall and not restart until problem corrected. I'm sure they are gouged for a thousand $ or more. Wet road conditions,extreme heat or cold,left turn while backing, jarring bumps, all trigger the dash to light up like christmas tree dinging alarm goes off steering shudders power is reduced. It's a huge distraction and safety concern for so many to be experiencing gm should stand up and take care of the problem.
Get abs, traction control, stable stability sensors on. In motion and when sitting still. Resets but comes right back on.
First my service abs traction control lights came on and while making left turns a loud metal grinding noise happened and my traction control light flashed. I took it to my local mechanic he replaced the bearing and sensors which helped with the service lights but the grinding still happened. The noise and traction control light still continued while turning just not as much as before. The mechanic replaced the part twice!! took it to my mechanic again because of the grinding and traction control flashing he drove it around and he could not make the noise happen so he could not fix or replace anything. It feels like the abs is braking on its own for no reason while I drive my 2013 Impala ltz. My mechanics can not find the problem and it seems neither can any Impala owner or mechanic. But I'm 99% sure when I drive it tonight to visit friends I will hear a metal on metal grinding noise I just hope not while im on the freeway where I can get killed. It happens while driving coming from a stop or as simple as me backing out of my driveway.
