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.

2020 GMC Sierra 1500 Interior Driveway Test | Still lagging behind

GM has caught nothing but grief for the interiors of its full-size pickups since they were redesigned. Some of it is about perspective. Ram blew everybody away with the new 1500’s interior, but it's not like the Ford F-150 is embarrassed by it. Chevy and GMC are. Even a top-shelf Sierra Denali doesnÂ’t live up to the luxurious environment its price tag would promise.  The trim of Sierra we're testing is an AT4, though. ThatÂ’s the light off-roading version of the Sierra thatÂ’s mechanically the same as the Silverado Trail Boss we recently reviewed. Looking at the interior from a pure functionality standpoint, the Sierra is perfectly fine at performing its truck duties. The seats are wide, flat and comfortable. It has huge armrests on both sides so you can stretch out as much as your truck stretches the boundaries of the road (seriously, this thing is huge). All the buttons in the center stack are well-labeled, easily found and big enough to stab away at without hitting the wrong one. It even has a volume and tuning knob. Yeehaw!  But look at the design. And the styling, or lack thereof. ItÂ’s plain and lacking in imagination. The whole center stack is just one big slab of black plastic, and the only splashes of color or style to distinguish it visually are bits of silver surrounding knobs and bits of gray surrounding air vents. That's certainly not enough to make it attractive. There are token pieces of "wood" inserted on Denali models, but they're almost hidden away along the center console and doors.  The screen looks as if itÂ’s scrunched into the top of the stack due to the vents curving in on both sides, making it look smaller than its perfectly acceptable 8-inch size. That just makes it more obvious that GM doesn't offer something to challenge the gigantic 12-inch optional screen on the Ram 1500. Not good, because size does matter when it comes to trucks, even if it's measured in a touchscreen's inches rather than engine displacement. LetÂ’s not discount how good all of the tech is in the Sierra 1500, though. GMÂ’s infotainment software that runs on the screen is glitch-free and runs like lightning through screens and menus. The performance is impressive, and of course both Apple CarPlay and Android Auto are on board.

GMC Hummer EV SUV to be fully revealed during Final Four in April

GMC is going to use another large platform to reveal the next chapter in its Hummer story. The GMC Hummer EV SUV will officially be revealed on Saturday, April 3, at 5 p.m. ET during the Final Four. That’s the SUV, not the truck, which has already been revealed. YouÂ’ll be allowed to place a reservation for the SUV at the same time as itÂ’s unveiled during the basketball games. There are no further details about the SUV, but weÂ’ll point out that a decent preview of what the SUV will look like is already out and can be seen here. ItÂ’s going to look a whole lot like the pickup, but will of course be fully boxed in, as an SUV is. WeÂ’ll know more about what GMC has in store in just under a monthÂ’s time.  In addition to the news about the impending SUV, GMC released video footage of the pickup version undergoing winter testing in MichiganÂ’s snowy Upper Peninsula. You can see the video below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. GM says that itÂ’s using this region to dial in and calibrate the truckÂ’s all-wheel-drive torque distribution, traction control system and stability control. Testing is conducted on snow, ice, and steep and split-friction grades. ThatÂ’s all GM is letting us in on for now, but at least we have the second version of the electric Hummer in our scopes now and will be eagerly anticipating its reveal.
