General Motors has issued a recall for 121,000 Cadillac ATS vehicles from the 2013, 2014, 2015, and 2016 model years. According to Detroit News, some of those cars could have a wiring flaw that has caused at least four fires.
The wiring in question is associated with the ATS' rear defogger -- specifically, the coil antenna module that powers it. Some of those modules may have "critically weak" terminal connections, and if the rear defogger remains on for too long, the modules can overheat. In four cases to date, that's led to fires in the ATS' rear pillar on the driver's side.
GM says that approximately 97,000 of the recalled Cadillac vehicles are registered in the U.S., with the remaining 24,000 found in Canada, Mexico, and in other countries. Despite the fires, GM says that it knows of no accidents, injuries, or deaths caused by the wiring flaw.
If you own one of these vehicles, you'll receive a recall notice by mail. Afterward, you'll be able to take your car to a Cadillac dealer, who will update the software on the Electronic Climate Control module. That update will prevent the rear defogger from turning on (and staying on) automatically.
Should you have additional questions, you're encouraged to contact Cadillac customer service at 800-458-8006 (within the U.S.), 800-263-3777 (in Canada), or 905-644-4112 (elsewhere).
