Chevrolet Silverado 2500 Recall 21V496: Engine block heater cord can short and cause fire

What this recall means for you

Certain 2017-2018 Chevrolet Silverado and GMC Sierra 2500 and 3500 trucks with the optional engine-block heater cord may develop an electrical short circuit in the heater cable or in the terminals that connect the cable to the block heater. This short circuit can increase the risk of a fire.

If your vehicle is affected, a dealer will replace the engine block heater and heater cord at no cost to you. Owners whose heater has been disabled as an interim fix will be contacted and offered replacement block heaters and cords free of charge under a separate customer satisfaction program. Vehicles previously included in recall 19V-328 will have the heater cord replaced and rerouted, also at no charge.

You can check whether your vehicle has open recalls by entering your VIN at the NHTSA or GM websites, or by calling GMC customer service at 1-800-462-8782. GM's recall number for this campaign is 212329840.
