GM 8-speed transmission lawsuit granted class action certification

A story on Autoblog about potentially faulty 8-speed automatic transmissions from General Motors in 2019 has, as of the day this was published, 166 comments, mostly from owners of cars and trucks who say they are experiencing "a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." At the time, lawyers were seeking statewide classes in at least six states. As of today, the Detroit Free Press reports that a judge has granted class action status to a lawsuit brought by 39 plaintiffs across 26 states covering the transmission issue. The lawsuit specifically applies to vehicles that are equipped with GM's 8L90 or 8L45 8-speed automatic transmissions made between 2015 and March 1, 2019. Both of these transmissions are similar units, the 8L45 being slightly lighter version used in fewer vehicles than the beefier 8L90, and are designed for front-engine, rear- or all-wheel drive applications. The lawsuit alleges that the erratic transmission behavior makes some vehicles unsafe to drive. Ted Leopold, partner at Cohen Milstein and the court-appointed lead counsel for the case, said in a statement, "General Motors knowingly sold over 800,000 eight-speed transmission vehicles, which they knew to be defective for years, and yet made the business decision not to tell its customers before purchase." He added, "Dealers were directed to tell the customers that harsh shifts were ‘normal' or ‘characteristic.Â’ Such decision making is both highly irresponsible and emblematic of what GM believes it can get away with." The vehicles included in the court order with potentially faulty transmissions includes: 2015-2019 Chevrolet Silverado 2017-2019 Chevrolet Colorado 2015-2019 Chevrolet Corvette 2016-2019 Chevrolet Camaro 2015-2019 Cadillac Escalade and Escalade ESV 2016-2019 Cadillac ATS, ATS-V, CTS, CT6, and CTS-V 2015-2019 GMC Sierra, Yukon, Yukon XL, and Yukon Denali XL 2017-2019 GMC Canyon Some additional details of the lawsuit can be found at the Cohen Milstein site, including claims that "since 2015, GM has issued thirteen versions of a “technical service bulletin,” or “TSB,” related to this shifting issue alone." The statement from Cohen Milstein says that a "second action regarding GM vehicles with 8L transmissions is also underway in Battle v. General Motors, LLC, 2:22-cv-108783.

2024 GMC Hummer EV SUV First Drive Review: Still impressive, even out of its element

SAN FRANCISCO – Our first experience with the GMC Hummer EV in any form was spent in an environment clearly ideal for such a vehicle. That first drive of the production-ready truck was in Arizona, a place with large, open freeways and rocky, desert terrain. Notably, they were areas that could showcase the Hummer's strengths: enormous power and acceleration, a lack of trees or narrow lanes to hinder its size, and sufficiently rocky terrain to demonstrate its remarkable off-road abilities. So it was particularly strange that the media's first experience with the Hummer EV SUV would involve the tight streets and twisty mountain passes of San Francisco and Napa Valley, locations that certainly would seem to put the Hummer on the back tire. In some ways they certainly did, but at the same time, they revealed the Hummer is surprisingly capable out of its element, and maybe even a good fit for the area. The start of our driving time involved leaving downtown San Francisco and heading up Highway 29 to Napa where GM had set up a number of demonstrations like those at the truck first drive, and where our winery hotel was. In the birthplace of Tesla, where Models of all letters and number are ubiquitous, the monster black Hummer definitely stood out. And not just for its sheer size: it is the technological flagship of General Motors, perhaps the most traditional of American car manufacturers. On the other hand, the locale also felt appropriate given that flagship status, from its flashy instrument and infotainment displays, to its acrobatic suspension and steering systems. This is as good a time as any to go over what makes the Hummer EV SUV different from the truck. Obviously it has a solid roof over a cargo area instead of an open bed. It's also the smaller of the two giants: total length is 20 inches shorter (excluding the spare tire) and the wheelbase is 8 inches shorter. That pays a few dividends in maneuverability both on and off road. The turning circle of the SUV is 1.7 feet smaller, at 35.4 feet, which is almost 3 feet tighter than that of the Chevy Bolt EUV. The breakover angle is also improved by 10.6 degrees (49 at max ride height) and the departure angled by 2.2 degrees (34.4 at max ride height). Though the bed is gone, the interior cargo space is certainly spacious, with maximum capacity of 81.8 cubic feet with the rear seats folded perfectly flat into the admittedly high load floor.

2023 GMC Sierra Review: Upscale and off-road capable

Pros: Quiet and torque-rich Duramax diesel; premium interior; big touchscreen on most trims; great trailering tech Cons: Worse ride than most rivals; AT4X priced like a Raptor but doesn't go like a Raptor The 2023 GMC Sierra half-ton pickup is a slightly more upscale cousin of the Chevy Silverado, but didn’t always feel like it. After a refresh last year, the Sierra actually delivers on the upscale part, for the most part of the equation with a comfortable, high-quality interior and better technology in most trim levels. ItÂ’s massively configurable, with four available engines and five different cab/box combinations. ItÂ’s also quite capable off-road with that AT4, AT4X and the soon-to-arrive AT4X AEV Edition. WeÂ’re fond of the diversity of tech available in the Sierra, whether itÂ’s the Google-powered infotainment with large, easy-to-use screens, a clear head-up display, numerous camera feeds for trailering and off-roading, or GMÂ’s Super Cruise advanced driver assistance system. We just wish that last one was available on more than just the Denali trims. If youÂ’re looking for a truck whose capability is matched by its livability, the GMC Sierra is worthy of your consideration, though you can find better ride quality in other brands (we enjoyed the ride in the AT4X, however). And while the AT4X has some true off-road capability, if youÂ’re looking for a Baja-blasting supertruck, though, youÂ’ll find better with the Ford F-150 Raptor and Ram Rebel TRX. If you donÂ’t need the nicer interior or extra tech, you might find something more matching your needs and pocketbook with the Ford F-150, Ram 1500 or even GMÂ’s own Chevy Silverado. ItÂ’s hard to go wrong with any of those nameplates.

After some pleasant updates for the 2022 model year, the changes for 2023 are relatively minor. The price went up, unfortunately. The available 3.0-liter Duramax turbodiesel has been revised for more power and efficiency. Later in the year, the AT4X AEV Edition will add even more off-road capability to this luxurious pickup. There are also some new exterior colors available, a new Graphite Edition for the Pro trim, and new 22-inch ultra-bright wheels for the Denali Ultimate.
