GM recalls Silverado and Sierra HD diesels again for block-heater issue

Chevrolet Silverado and GMC Sierra Heavy Duty vehicles equipped with a Duramax diesel engine and an optional engine-block heater are being recalled by General Motors (GM). According to the National Highway Traffic Safety Administration (NHTSA), a short circuit in the connection to the block heater might result in a fire.

A block-heater problem can be identified by five indicators: smoke or a burning smell; weak or poor performance from the block heater; tripped circuits or blown fuses; damage to the block heater, heater cable, or engine components; and block-heater coolant spilling or pooling beneath the vehicle.

  • A Duramax diesel 6.6-liter V-8 engine and an engine heater power cable are included in the recall, which applies to the 2017-2019 model years of the Chevrolet Silverado 2500/3500HD and GMC Sierra 2500/3500HD pickup trucks.
  • The recall affects 208,546 Chevrolet Silverado 2500HD pickup trucks and 122,728 GMC Sierra 2500HD pickup trucks.
  • The recall remedy did not work in this case.
  • According to GM’s papers with the National Highway Traffic Safety Administration, the next step may be to disable the function.
  • Dealers will do the change at no charge, and General Motors will refund owners who have already had the maintenance completed at their expense.
