GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.

2015 GMC Yukon Denali

Automotive enthusiasts often wonder aloud - ourselves included - why General Motors would choose to keep GMC while sending Pontiac (and Saturn, and even Oldsmobile before it) into the great automotive graveyard in the sky. The answer, as is so often the case, is profit. It's much easier for GM to rake in money hand over fist by rejiggering the trucks, crossovers and SUVs that it would already be developing for Chevrolet and making them a bit more luxurious and *ahem* "Professional Grade" with new grilles, badges and unique packaging for GMC.
While it may sound like we're being cynical, we totally approve of GM's fullsize SUV strategy. The least-expensive way to get into the fold is with the Chevrolet Tahoe, which starts at $45,595 with a 5.3-liter V8 engine and a cloth interior. Bumping that same Chevy to LTZ trim and its $59,995 sticker price lands a much nicer leather-clad interior and more techno-bells and whistles than you can shake a stick at. But it still looks like a Tahoe, and it still comes with the smaller 5.3-liter engine. Or, you could do what we'd do: Walk into your GMC dealer and take a look at the Yukon Denali. Here's why.

Hummer EV to be sold at only about half of GMC dealerships

The new 1,000-horsepower Hummer EV will be sold under the GMC brand, but you won't find it in every GMC showroom. Currently, just about half of GMC's dealers have agreed to take on the electric truck, Buick GMC VP Duncan Aldred told investors on a conference call last week. According to Muscle Cars and Trucks, there are a number of reasons for the irregular availability. For one, there's the cost of upgrading dealerships to sell and service a fully electric vehicle. Stores would need to be upgraded with charging stations, and service centers would require new tools and training to work on an EV. Then there's the customer experience. At $112,595, the initial Hummer EV Edition 1 caters to a different clientele than the traditional GMC truck. The planned EV3X trim level that arrives in late 2022 and EV2X arriving in spring 2023 will start at just below $100,000 and $90,000, respectively. Some sellers believe that customers paying six figures for a vehicle will expect certain niceties that will necessitate showroom upgrades as well. Complimentary doughnuts, at least. Furthermore, not all GMC dealerships are located in areas with customers willing to shell out that much cabbage for a new vehicle, especially an EV. An $80,000 base trim will be available in 2024, so perhaps more dealers will be willing to take on the truck by then. Finally, there's the Hummer EV's no-haggle pricing. Aldred was adamant on the call that customers see the same price on the internet as they do on the paperwork. It's part of the premium dealership experience that GMC wants to provide for its well-heeled clientele. Still, GMC appears to have no problem moving all the Hummer EVs it can build. Even with its lofty price tag, all Edition 1 trucks were sold out 10 minutes after GMC's announcement. Related Video:
