Campaign #18V595000 · 07/09/2018
Issue: General Motors LLC (GM) is recalling certain 2014-2016 Cadillac CTS vehicles, equipped with heated front seats. The flexible heating mats in the front seats may be damaged over time, resulting in the seat heaters producing excessive heat.
Risk: In cold ambient temperatures, the seat heaters in these vehicles can turn on automatically when the vehicle is remotely started. If a damaged seat heater is turned on while no one is inside the vehicle, the damaged seat heater can overheat, increasing the risk of a fire.
Fix: GM will notify owners, and dealers will recalibrate the body control module, disabling the automatic activation of the heated seat when the vehicle is remotely started, free of charge. The recall began November 1, 2018. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for the recall is 18286.
