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.

GM's Ultium EV platform finally shows up in Q3 sales numbers

General Motors has heralded its Ultium battery-electric platform as the future of its passenger car and truck lineup, but for the first two years of its existence, its impact on the marketplace has been virtually nonexistent. Well, that finally changed in the third quarter of 2023, and while the cars based on this architecture don't represent anywhere near the volume of GM's broader combustion portfolio, we're reaching a point where Ultium products are finally in view (and in the hands) of real-world shoppers. At this point, five U.S.-market Ultium models are in production: the GMC Hummer EV, Cadillac Lyriq, Chevrolet Blazer & Silverado EV, and BrightDrop Zevo 600. If you're not familiar with that last one, that's OK; it's a commercial product that you likely won't see on the road for some time. Together, these four combined for 4,257 sales in the third quarter alone — up from 2,663 for the entire first half of the year. While that may not seem like a significant uptick when viewed from altitude, the quarter-to-quarter numbers paint a clearer picture.  Let's toss out the stragglers first. The Chevy Blazer EV, and Silverado EV for example, are barely in production. GM delivered 19 Blazers and 18 Silverados in the third quarter and that's the entirety of their production runs so far. Likewise, GM's BrightDrop Zevo 600 delivery van effectively exists apart from the consumer marketplace, so its contribution of just 35 units can be set aside too. That leaves us the two you've heard of: the GMC Hummer EV and Cadillac Lyriq — models with high sticker prices and long reservation queues.  Through the second quarter (remember, we're talking six months here), GMC sold 49 Hummer EVs. No typo. In the three months that made up the third quarter, GM moved 1,167 of them. Not only is that a dramatic improvement over the first half, but it's more Hummers than GMC sold in the entirety of 2022 (854). Lyriq's improvement was less eye-popping on paper, but after moving just 122 total units in 2022 and 2,013 of them in the first half of 2023, Cadillac managed to up that figure to 3,018 units in the third quarter alone.  GM is betting its short-term EV future on the Ultium platform, so these trends need to continue if that's going to be a profitable wager.

Coronavirus shakes up America's truck market: GM outselling Ford and Ram

FCA, Ford and General Motors joined the rest of the U.S. auto industry in taking heavy volume hits due to coronavirus-related shortages of both cars and customers. The saying goes that a rising tide lifts all boats; it stands to reason, then, that a falling one would have the opposite effect.  However, as we learned Thursday, the automotive market can behave in unpredictable ways. While the F-Series remained the best-selling nameplate in Q1, GM's full-size trucks are now outselling Ford's again for the first time in years, and with this upward thrust from the General, FCA's Ram was unceremoniously booted out of a hard-earned second place.  While late-March sales declines hit just about every major automaker in one way or another, the model-by-model results weren't nearly so uniform. And because the market tends to be a zero-sum game, for every winner, there generally has to be a loser.  In this case, that winner was GM, and its rise had to come at the expense of another automaker, in this case, Ford. F-Series sales dropped 13.1 percent in the first quarter of 2020, while sales of GM's full-sized Silverado and Sierra surged nearly 28% in the same period. FCA's Ram lineup managed a steady-as-she-goes 7% increase. All-in, GM finished the quarter with 197,743 full-size trucks sold to Ford's 186,562. Here's the full breakdown: Ford F-Series: 186,562  Chevrolet Silverado*: 144,734 Ram P/U: 128,805 GMC Sierra: 53,009 *includes 1,036 Medium Duty sales Things are a but murkier in the midsize segment, where the Chevy Colorado slipped 36% to just 21,430 units sold — just a few hundred better than the slow-selling Ford Ranger's Q1 numbers. The GMC Canyon experienced an almost identical slide, finishing the quarter with just 4,483 units sold. For perspective, Jeep sold more than 15,000 Gladiators and Toyota's midsize Tacoma slipped less than 8%, finishing the quarter with nearly 54,000 sales.  We suspect this discrepancy in full- and mid-size truck sales comes from shifting incentives. Ford, GM and FCA would like to keep selling bigger trucks because there's far more profit margin built into their list prices. Even with tens of thousands of dollars in manufacturer money on the hood, big trucks still make money.  Since these automakers report quarterly, we won't get another good look at these numbers until July, but if you thought that 2019 represented the new normal for U.S. auto sales, well, think again.
