GM has announced a large recall of 331,274 pickup trucks over potential engine fires. The recall takes in 2017-2019 Chevy Silverado 2500 and 3500, and 2017-2019 GMC Sierra 2500 and 3500. Those potentially affected are powered by the Duramax diesel 6.6-liter engine but also have an engine block heater cord.
These Silverado and Sierra pickups have been in another recall campaign
This is the second time for some trucks in this group. Certain 2500 and 3500 Silverados and Sierras were also recalled for potential fire risks back in 2019. A short-circuit condition was the focus.
For this recall, GM is saying there have been no injuries or deaths to their knowledge. But the National Highway Traffic and Safety Administration says it received 122 complaints about the issue. It also says that it received reports of 24 fires taking place between December 2019 and May of this year.
What happens if a circuit or fuse blows?
If the situation occurs drivers will see smoke or a burning smell, poor block-heater performance, tripped circuit breakers, or blown vehicle fuses. There could also be damage to the block heater, heater cable, or other engine components. And you may notice some engine coolant pooling under the truck.
Bring your truck to the dealership if you have a potentially affected model. Service techs will disable the heater. Then Chevy will replace the block heater and cords in a separate customer satisfaction effort.
Here’s where to go if you have questions or concerns
Dealerships were notified about the recall on July 1. Truck owners will begin to receive their notices beginning in mid-August. Electronics Components International from Canada manufacturers the block heater components according to Automotive News.
If you are concerned or have questions you can either go to GM’s recall website or the NHTSA’s site for further information and instructions. Have your truck’s VIN handy to provide either site for more information.
