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.

GMC's electric Hummer could someday serve alongside the Humvee in the U.S. Army

Every civilian Hummer model traces its roots to AM General's Humvee, which made its combat debut when the United States invaded Panama in 1989. Fast forward to the 2020s, and the tables have turned. The born-again Hummer that will arrive with an electric powertrain and a GMC emblem could spawn a military-spec truck. "[The upcoming Hummer] is a full-size truck with 400 miles of range and 1,000 pound-feet of torque, it's a very highly capable vehicle. That could provide a great base platform for an electric vehicle to be used in the military context," said David Albritton, the president of General Motors Defense, in an interview with GM Authority. Although he didn't sketch out the Hummer's role in a battalion, its range, torque, and dimensions would theoretically make it well-suited to carrying soldiers, weapons, and/or gear like radio equipment. It wouldn't necessarily look like the production model (shown above in a preview image). General Motors Defense might use its basic platform and its powertrain technology to build a purpose-designed off-roader, like it did with the Colorado Infantry Squad Vehicle (ISV) it will soon begin manufacturing for the Army. The ISV shares 90% of its parts with the regular-production Chevrolet Colorado, but the two vehicles look nothing alike. Securing a contract with the American military is easier said than done, and Army officials haven't publicly expressed an interest in sending the upcoming Hummer into a war zone. We'll learn more about what a battle-ready electric truck could look like after the showroom-bound model makes its debut. In the meantime, Humvee production continues, and AM General introduced a comprehensively updated model named NXT 360 in 2018. Related Video:     Green GMC Hummer Truck Electric Military

2017 GMC Canyon steals Cadillac's V6 for a little more power

GMC is fortifying the Canyon with a new powertrain and two new trim levels for 2017. GMC will give the Canyon the 3.6-liter V6 found in the Cadillac ATS, CTS, CT6, and XT5 crossover. The engine will be matched to an eight-speed automatic transmission, which also can be found on Cadillacs, the new 2017 Colorado, and other General Motors vehicles. The new engine comes with variable valve timing, improved direct injection, and Active Fuel Management, which is a form of cylinder deactivation that shuts off two cylinders to increase fuel efficiency and performance. Power is up from 305 to 308 horsepower, while torque increases from 269 to 275 pound-feet of torque compared to the old 3.6-liter V6. With the new transmission, the Canyon benefits from a higher first gear ratio, which should help drivers get off the line more easily when towing large cargo, and lower overdrive ratios for improved fuel efficiency. The 2016 model had a six-speed automatic. The Colorado also gets the eight-speed transmission for '17. GMC previously announced the All Terrain X and Denali models. The All Terrain X trim is offered on the SLE model and comes with the new 3.6-liter V6 engine or the 2.8-liter Duramax turbo-diesel. The All Terrain X gets Goodyear Wrangler DuraTrac P225/65R17 all-terrain tires, a body-color grille surround and matching rear step bumper, bespoke 17-inch aluminum wheels, and a spray-on bedliner. The truck also is fortified with Hill Descent Control and an off-road suspension. The Denali carries the flag as the most luxurious Canyon model and gets a Bose seven-speaker audio system, more chrome, and interior upgrades. In addition to the new models and the powertrain, the 2017 Canyon will be offered with new colors – Dark Slate Metallic, Mineral Metallic, and Red Quartz Metallic – a new IntelliLink radio with a seven-inch touchscreen, a heated steering wheel as an optional extra, and Standard Teen Driver Mode. The 2017 Canyon, with all of its changes, will be available in the fourth quarter of the year.
