While driving my car yesterday my service stabilitrak light came on and I’m getting a code U2100. The light comes and goes, it hasn’t been staying on longer than 20-30 minutes. The car seems to have no issues and I can’t find much online about this code on a 2010 Chevy Camaro LT. Any help would be greatly appreciated, thank you

Dealer.

Your car is a major purchase. Don't screw around.
