Known issues on the 2015 CTS. Three recalls are on federal record for this model year. The first covers the front seat heaters: in cold weather the heaters can turn on automatically when the vehicle is remotely started, and a damaged heating mat left running with no one inside can overheat, increasing the risk of a fire. The second covers the brake pedal assembly, where the bracket between the pedal and the brake actuating rod may fracture during normal operation, leaving the driver unable to apply the brakes. The third covers the driver's frontal air bag inflator module, which may rupture during deployment and send sharp metal fragments toward the driver or other occupants, risking serious injury or death. Owners have filed 47 complaints for the year.

Tracing an intermittent seat heater fault, inspecting the brake pedal bracket, or handling a recall-related repair on this car calls for the correct torque specs and wiring diagrams for its specific engine and trim.
