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.

General Motors designers sketch the GMC pickups of the future

It's been a busy few years for GMC's team of stylists. They penned a new look for the Yukon and the Yukon XL, and they gave the Sierra 1500 a nip-and-tuck that we'll discover in the coming months. Overhauling these hugely significant models hasn't stopped them from exploring how the firm's design language can evolve. General Motors Design posted two forward-thinking renderings on its official Instagram account that illustrate two ways to move GMC's design identity forward. Karan Moorjani, who works as an exterior designer for the company's autonomous and electric vehicle division, created a truck that breaks all ties with the Sierra. It's characterized by a tall front end with a wide grille and thin LED headlights, sculpted sides, and an unusually low cab. Generously-sized fender flares and tires suggest Moorjani envisioned it as a serious off-roader. Joe Boniface, a member of GMC's Strategic Advanced Design team, took a more realistic approach to moving the design language forward and away from sister company Chevrolet's. His rendering shows a Heavy Duty model with a Denali-branded grille that takes up most of the real estate on the front end and encompasses horizontal rows of LED daytime running lights. It wears less chrome than the current-generation Sierra HD. Nothing suggests either truck is currently on its way to production; General Motors Design regularly publishes sketches from the brand's stylists. Its fascinating Instagram account also shows a Cadillac off-roader, a battle-ready Chevrolet pickup, and a high-riding, open-top two-seater with General Motors emblems that looks like a race car for the Moon.  "Often, these works are not intended for production," a GM spokesperson told Autoblog. "Instead, designers create them to hone their creative skills, to try new shapes or themes, and sometimes simply for the fun of sketching something badass. The GM Design Instagram account was launched to share some of the most compelling, most badass works GM Designers produce." They're sketches created for the sake of sketching, but they give us a peek at the ideas floating around the minds of the men and women who will draw the next generation of General Motors products.

GM's Super Bowl ad puts Will Ferrell and EVs in Netflix shows

GM is kicking off the automotive Super Bowl commercial season with EVs and Will Ferrell. The ad highlights GM's new relationship with Netflix in which the automaker's many upcoming electric cars and trucks will appear. More specifically, the ad has Will Ferrell appearing in settings from major Netflix TV movies and shows such as "Army of the Dead" and "Squid Game," talking about how there's no reason not to have EVs there. And then he also appears with EVs in shows where they don't make sense, such as "Bridgerton" and "Stranger Things," but only to reassure people that Netflix won't be shoving new cars where they don't fit in. The GM lineup on display is pretty varied, with the GMC Sierra EV, Hummer EV, Chevy Blazer EV, and Cadillac Lyriq all making appearances. Most interesting is the Chevy Silverado EV Trail Boss in the "Stranger Things" part. Chevy hasn't said much about it beyond a teaser and saying it'll be a late addition to the line. It looks pretty much like the truck in the teaser with the black plastic front fascia and fender flares. But it gets different wheels, Trail Boss badges on the rear pillars, and a gloss black roof like the RST trim. Related video: 2024 Chevy Silverado EV | 2022 Chicago Auto Show
