GM cars and SUVs recalled for leaking transmission fluid

General Motors is recalling more than 194,000 vehicles from 2018 to 2020 due to transmission fluid leaks. The leaks stem from an auto stop-start component that may have been installed with loose or missing bolts. The leaking fluid can affect the transmission's performance, and if it leaks onto a hot exhaust component, could potentially cause a fire. GM says that to date, it knows of no accidents or injuries related to the defect. The issue affects models from all four GM divisions. From Chevrolet, the affected vehicles are: 2018 Malibu, 2018–2019 Cruze, 2018–2020 Equinox, 2018–2020 Traverse, 2019–2020 Blazer At Buick, the following models are included: 2018–2019 LaCrosse, 2019–2020 Encore, 2019–2020 Enclave, At GMC, the recall includes: 2018–2020 Terrain, 2019–2020 Acadia Cadillac has two affected vehicles: 2019–2020 XT4 and 2020 XT6 The recall is scheduled to begin in mid-December. Owners of the affected vehicles will be contacted. Dealers will inspect the transmission accumulator, and replace those with loose or missing bolts.

GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.

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.
