i have the same problem! you talking about the VSC light? cause that and all the other lights have gone off twice for me this past couple months. First time i was just driving and it turned on. I restarted my car and it dissapeared. Next time happened recently like 3 weeks ago, i left my car to get the brakes replaced and the lights were on when i got my car again. i showed the mechanic but he said it was on when he got it...He plugged in a scanner and it said something like "cylinder 5 is misfiring" he reset the system and i havent seen it since. I really hope this doesnt expand into a problem that costs alot of money. But if it makes you feel better im experiencing the same problem haha. And i would also like an answer! btw what year is your car? mines an 06
i had that issue for the longest time. eventually it ended up with my traction control completely disabled. the dealer found it to be a dead o2 sensor. replaced it and reset the ecu.
they also found the dash to be loose and redid it and they pinched a wire which also caused lights going on and off. they replaced the wire and fixed that too. figured this might help one way or another
