Engine block heater issues force GM to recall 324,226 diesel heavy duty trucks

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.

2020 GMC Sierra Heavy Duty First Drive Review | King of the haul

JACKSON HOLE, Wyo. — The 2020 GMC Sierra Heavy Duty is a bit of a mixed bag. It excels at the tasks an owner is likely to require from a massive pickup truck, but the interior is a definite letdown. Taken as a whole the truck boasts several class-leading specifications and features that make up for the lackluster look and feel of the cabin. And it's much more successful than the mechanically similar Chevy Silverado HD, which shares the Sierra's weaknesses but few of its subjective strengths. GMCÂ’s Sierra HD may share most of its major bits and pieces with the Silverado, but the strongest reason to pick the GMC over the Chevy is that the SLE and SLT trims of the Sierra HD are legitimately handsome. And the rugged, off-road-themed AT4 package is new for 2020 with a blacked-out look that we think a lot of buyers are going to love. Even the ostentatious, chrome-dipped Denali trim looks classy compared to the in-your-face look of FordÂ’s Super Duty line. The same canÂ’t be said for the Silverado HD, which, depending on trim level, varies from garish to just plain ugly. The six-function MultiPro tailgate is the next major differentiator. ItÂ’s not perfect — and mounting a hitch ball in the receiver renders some of its functionality unusable — but itÂ’s unique and potentially very useful to a subset of truck customers. WeÂ’ve covered MultiPro several times already, but if youÂ’re still not clear on its advantages, watch the video below for a demonstration (that's a light-duty Sierra in the video, but the tailgate works the same).

Another unique selling proposition is the AT4 trim, since Chevrolet doesnÂ’t (yet) offer its Trail Boss package on the Silverado HD. The most obvious competitor to the Heavy Duty AT4 is the Ram Power Wagon, and the GMCÂ’s 3,615 pounds of payload and 18,500 pounds of towing capability handily outdo the RamÂ’s ratings of 1,660 and 10,620. Granted, the trucks arenÂ’t aimed at quite the same buyer — the Power Wagon has legit off-road credibility thanks to upgrades like its electronically disconnected sway bars, 12,000-pound Warn winch, and a forward-facing trail camera. But unlike the GMC Sierra AT4, it isnÂ’t available with a diesel. No matter; those aiming for a rough-and-tumble appearance in a heavy duty now have a couple options.
