General Motors has issued a recall for several
2017-2019 Chevrolet Silverado and GMC Sierra pickup trucks are affected by a short-circuit issue.
The recall affects models equipped with the automaker’s Duramax 6.6-liter V8 diesel that include the optional engine-block heater cord. According to the company, a short circuit can occur in the engine-block heater cable or at the terminals that connect the cable to the block heater.
This can trigger coolant leaks, and customers may notice smoke or a burning smell, poor block-heater performance, tripped circuit breakers or blown vehicle fuses, damage to the block heater, the heater cable, or engine components, and block-heater coolant pooling under the vehicle.
The Detroit company said it has 24 reports of fires potentially caused by this problem from December 3, 2019, through May 28, 2021, and that it is not aware of any injuries related to this issue.
Vehicles involved in the recall include 208,546 Chevrolet Silverado 2500 and 3500 models built between July 18, 2016, and May 10, 2019. In addition, 122,728 GMC Sierra 2500 and 3500 models also built between July 18, 2016, and May 10, 2019, are involved.
