Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The traction control system lights come on during wet weather and or turning. The anti-locks brakes fail to work unless pressed completely down. No accidents have occured at this time, but a few close calls. The car is being returned to a GM dealer to inspect and report the problem. The brakes have always had a spongy feeling since date of purchase and since the brake recall was adjusted. I would hope that this problem can be investigated before there is a fatal incident since the anti-lock brakes become very non-responsive when the traction control system fails.”
