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.

GMC talking to dealers about possible Jeep Wrangler competitors

With respect to the team at GMC, it's pretty much fair to say the manufacturer prospers on a lineup of nothing more than gussied up Chevrolets. The brand's successes aside, GMC can be boiled down thusly – the Sierra is a Silverado, the Terrain an Equinox, the Canyon a Colorado and the Acadia is a Traverse, albeit with sometimes dressier duds. Strictly speaking, it's not that simple – Acadia and Terrain have siblings beyond the Bowtie – but the brand is remarkable for its lack of distinctive models. That could change, though, as The Wall Street Journal is claiming General Motors has broached the idea of a building a GMC-badged competitor to the Jeep Wrangler during a meeting with dealers. WSJ claims the new off-roader would "borrow cues and capability" from the defunct Hummer brand. That, of course, could mean many, many different things. While the original Hummer, the H1, was an exceptionally capable vehicle off-road, the H2 and H3 weren't nearly as single minded. It's unclear if a Hummer-inspired, off-road-ready GMC would lean more towards the former than the latter. According to WSJ's report, the GMC Jeep appears to be in the very, very early planning stages, with one unnamed source saying the idea was "being kicked around real hard." GM is still courting dealers for feedback, while it refused the Journal's request for comment. What are your thoughts? Is a Wrangler competitor long overdue for GM?

GM drops diesel engines for 2020 Chevy Equinox and GMC Terrain crossovers

GM is officially discontinuing the diesel engine in the Chevy Equinox and GMC Terrain for the 2020 model year. The 1.6-liter turbodiesel was always an oddball of an engine in the compact crossover segment, and now the experiment has come to an end. The Car Connection initially reported the news, and a GMC spokesperson, Stuart Fowle, confirmed it to us this morning.  “A huge majority of our Terrain customers have opted for one of our two gas engines," says Fowle. We canÂ’t say this eventuality comes as a massive surprise, as we saw news from couple of months ago that GM was dropping all-wheel drive from the diesel-powered cars for 2020. Low demand was cited as the reason for that cull, and itÂ’s the same for the little GM crossovers this time around, too. These vehicles were the only ones powered with a diesel engine in their class, but thatÂ’s going to be changing. Just as GM is going away from the diesel, Mazda is finally bringing its diesel to market in the CX-5. YouÂ’ll only be able to get that engine in the most expensive ($42,045) trim level, combined with all-wheel drive, though. The cheapest Equinox diesel starts at a comparably low $30,795. ThatÂ’s a $2,400 upcharge over the base 1.5-liter turbo four-cylinder, and the value is questionable. Mileage is better, but diesel fuel is more expensive. Towing capability didnÂ’t increase over the base engineÂ’s 1,500-pound capacity, but the extra torque around town was nice. As diesels go in the U.S., this one was rather rough and noisy, possibly contributing to some turning their noses up after a test drive. Perhaps another reason for its demise was that the much quicker 2.0-liter turbo Equinox was only $100 more than the diesel. This engine offered significantly better towing at 3,500 pounds, too. You can read all about what we thought of the diesel in our first drive review here, but the 2019 model year is the last one if you had it on your shortlist.
