An investigation into a 2015 Cadillac CTS fire will have owners of certain 2014-2016 Cadillac CTS vehicles returning to their dealerships for repairs. According to the recall report, occupant pressure on the seat could bend and damage the flexible heating mat inside. If the damaged heater is turned on without an occupant in the seat, the open airflow could cause areas of high electrical resistance. The seat could overheat and melt, increasing the risk of fire.
Dealers will correct the problem by re-calibrating the body control module to deactivate the automatic activation of the heated seats during remote start. Signs that a problem exists include a seat heater that stops working, experiences uneven heat or excessive heat in spots.
GM has issued a recall for certain Cadillac, Chevrolet and GMC trucks and SUV's for a problem affecting the electric power steering (EPS). According to the recall report, certain driving situations that demand high current, such as low speed turns, could create a low voltage condition that may temporarily disable steering assist. A sudden loss and return of power steering could make it difficult for drivers to steer the vehicle, especially at low speeds.
If EPS is lost the driver will be alerted through an illuminated warning on the driver information center (DIC). Other electrical systems, such as the radio, stabilitrack, DIC, chimes, door lock, air conditioning or cruise control may stop working at the same time or just prior to loss of the EPS.
The vehicles affected include:
Certain GM vehicles may have been improperly serviced under Safety Recall 16V-069, issued in February 2016. A lack of thread adhesive applied to the brake pedal pivot nut could cause the brake pedal to loosen and become inoperative. The loose pedal could also interfere with the accelerator pedal, increasing the risk of an accident.
Those receiving notices will be asked to return to their dealer who will reinstall the nut with adhesive and increased tightness.
The vehicles affected include:
Certain Buick, Cadillac, Chevrolet and GMC vehicles may have been manufactured with brake pistons that were not properly chromed and tempered. As a result, hydrogen gas trapped within the piston body could be released into the brake system when it contacts brake fluid. The air in the system may cause the brake pedal to feel soft or spongy and could reduce rear brake performance.
According to the manufacturer, the trapped gas should be released within 23 days of assembly and will be noticeable to the driver within 15 days of assembly. GM is asking owners to return to their dealerships to have the bake system bled.
