General Motors (GM) has issued a recall for a reported 159,000 pickup trucks in Canada for a faulty rear window defroster that could overheat and lead to a fire. The recall affects the Chevrolet Silverado and GMC Sierra half-ton and heavy-duty trucks that are equipped with a power sliding rear window.

The issue with the rear defrosters in the trucks is caused by a faulty circuit. GM said if a fire does not occur, the rear defroster circuits can melt and emit smoke. However, the risk of a fire is high and can lead to significant damage to the vehicle and could cause injuries to the passengers riding in the truck, according to GM Authority.

The recall includes the 2014 to 2018 Chevrolet Silverado 1500 trucks, 2015 to 2019 Chevrolet Silverado HD trucks, 2014 to 2018 Chevrolet Silverado LD trucks, 2014 to 2018 GMC Sierra 1500 trucks, 2015 to 2019 GMC Sierra HD trucks, and 2014 to 2018 GMC Sierra LD trucks.

According to the news outlet, GM is looking into the issue and is considering the best remedy to repair the problem. Until a repair is determined, the company is advising truck owners not to use their rear defrosters until a repair by an official GM dealer has been made.

The interim repair for the rear defroster issue includes removing the fuses for the rear window defroster. A second notice will be issued to truck owners when a repair solution has been identified, GM Authority said.

Questions about the recall can be directed to GM Canada’s Customer Assistance Center at 1-800-263-3777.

The recall only affects trucks that are located in Canada. There have been no recalls for the rear defroster issue in the U.S.

The recall number is N192220470.
