GM is recalling nearly 325,000 heavy-duty trucks because a faulty engine block heater cord may fail, increasing the risk of fire, according to the National Highway Traffic Safety Administration.

The automaker is recalling 2017 to 2019 Chevrolet Silverado 2500 and 3500 heavy-duty trucks, and GMC Sierra 2500 and 3500 heavy-duty trucks. Also included in the recall are 2019 Chevrolet Silverado 4500, 5500, and 6500 commercial trucks.

Only trucks equipped with 6.6-liter Duramax diesel engines and optional engine block heaters are affected, NHTSA says.

Engine block heaters plug into an external power outlet and warm the engine, making it easier to start in very cold weather. Both the cord and the connection between the cord and the block heater may short circuit, which could cause a fire.

GM says that owners may notice smoke or a burning smell, poor performance from the engine-block heater, or coolant from the block heater pooled under affected trucks. When in use, the block heater may blow vehicle fuses or trip the circuit breaker of the outlet it’s plugged into.

GM told CR that it is aware of 19 fires related to this issue but no reports of injuries, crashes, or fatalities.

Ford trucks also were recalled recently for an engine block heater issue.

If you plug your car’s 17-digit vehicle identification number (VIN) into NHTSA’s website and a recall doesn’t appear, it means your vehicle doesn’t currently have any open recalls.
