Here at Diamond Buick GMC, we take safety seriously. However, sometimes errors occur, and a much-dreaded recall becomes necessary. We know recalls are never fun, but it is important to be aware of potential dangers when the time comes. Unfortunately, if you own a Chevy Silverado or GMC Sierra from the last few years, a recall alert has been issued.

General Motors is currently recalling about 325,000 Chevy Silverados and GMC Sierras throughout the U.S. GM began this recall on April 25 after notifying the NHTSA that potential dangers related to engine-block heaters have become apparent.

The biggest concern is damage to components, with a rare chance of fire occurring. Thankfully, less than 20 fires have been reported, with no injuries or deaths resulting from the malfunctions. The issue can only occur if the engine heater is turned on.

The Chevy Silverado and GMC Sierra trucks in question all have Duramax 6.6-liter diesel engines with the optional engine-block heater.


Specific models targeted in this recall are the following:


  • 2017-2019 Chevrolet Silverado 2500 and 3500 heavy-duty trucks
  • 2019 Chevrolet Silverado 4500, 5500, and 6500 commercial trucks
  • 2017-2019 GMC Sierra 2500 and 3500 heavy-duty trucks.


Possible warning signs of the issue occurring include:


  • Smoking or burning smell
  • Coolant drippage under the vehicle
  • Tripped circuit breakers or blown fuses.

If you and your vehicle are affected by this recall, we strongly urge you to contact our servicing department to schedule a temporary fix. You can schedule an appointment online or give us a call at 1-320-313-1743. This temporary fix involves cutting the cable that provides power to the engine heater, ensuring it cannot operate in the currently faulty state.

Other than to travel to the dealership, we ask owners of the recalled vehicles not to operate their vehicle unless they have had the temporary fix applied. We have also halted all sales of these models for the moment.

At this time, no permanent fix is available for the engine-block heater. Once a permanent fix is found, repairs will be made at no charge to all affected truck owners. Drivers who have had the temporary fix applied will be notified to return when this fix is released.

Engine-block heaters offer convenience as they speed up the warming-up process of your vehicle. However, in these recalled trucks, the heater cord or components can malfunction and catch fire. In the event of a fire, the block heater, cable, and other parts may perform poorly or incur damage.

Affected owners may contact GM customer service for more information. Their contact phone number is 1-586-596-1733. Please reference the number for this recall, N182206310.
