General Motors

has issued a recall on 324,226 diesel

heavy duty trucks

that could be susceptible to short circuits, and consequently, potential fire. The recall affects several models of heavy duty

Chevrolet

Silverados and

GMC

Sierras with optional engine block heaters.

GM

is

recalling

seven different truck models spread across three years. The recall affects the 2017-2019 Chevrolet

Silverado 2500HD

, 2017-2019

Silverado 3500HD

, 2019 Silverado 4500HD, 2019 Silverado 5500HD, and 2019 Silverado 6500HD, plus the

2017-2019 GMC Sierra 2500HD

and 2017-2019

Sierra 3500HD

. Specifically, it includes these models with the 6.6-liter Duramax

diesel

engines and the optional engine block heater.

The recall technically deals not with the engine block heater itself, but the way it is connected. According to

NHTSA

campaign No.

19V328000

, the engine block heater cord or the terminals that link the cord to the heater could short circuit. A short circuit could potentially damage engine components and result in a fire. According to

The Detroit News

, 19 fires have been reported but nobody has been injured.

GM has yet to figure out a fix, and thus has not yet released a notification schedule for affected customers. If you believe your vehicle is part of the recall, contact GM customer service at 1-586-596-1733 and use reference number N182206310.
