My traction control and stabilitrac lights have been coming on quite a bit the past 4-5 weeks. When I turned the car off and then restarted it, everything was back to normal. It was very annoying and also with it being winter time, probably when I need it the most, I decided to use the search function on here. It seems it usually is related to the infamous steering wheel position sensor but from my research the part isn't that cheap and replacing it is a big PITA. I read in one of the posts that sometimes the sensor doesn't "read" the steering wheel as being straight when it actually is and that causes the system to malfunction. Well I decided to make sure that every time I parked my car that the wheels were dead straight and not turned to the right or left any at all. I've been doing that for about 6 days now and the traction control and stabilitrac lights have not come back on once. Maybe it's a fluke, maybe it's luck, who knows, but I just wanted to share my experience and what has fixed my issue so far, best of all, it's free.
