VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM
What Happened
Your ATS sedan has a tiny coil antenna that helps power the rear defogger system. In some 2013-2016 models, this antenna can heat up too much if it's used too much or stuck in a loop.
Risk if Unfixed
If the antenna gets too hot, it could catch fire, which is a serious safety risk that could cause damage to your vehicle or even harm you.
Free Fix
Your Cadillac dealer will update the climate control module to prevent the rear defogger from turning on automatically, and this service is free. You'll get a notification when it's time for the repair.
