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.

Do you guys like trucks?

Do you guys like trucks? If the answer is yes, boy do we have the show for you! The 2018 North American International Auto Show is lousy with 'em. Yeah, we saw the new Ram 1500, Chevy Silverado and Ford Ranger, but that's just scratching the surface. There are big trucks, little trucks, clean trucks, dirty trucks, old trucks, new trucks, red trucks, blue trucks. It's like a Dr. Seuss book. Anyway, we made a little video for you truck nuts (see what I did there?). Check it out above, and if you're looking for more serious coverage of the Detroit Auto Show, we've got it, along with a ton of images and other videos from the show floor. Enjoy!

2023 GMC Sierra AT4X AEV starts at $90,490

The 2023 GMC Sierra hid a surprise we didn't know to look for. We covered the pickup's pricing for next year, which included noting the $3,395 increase on the price of the $83,595 AT4X trim. Only the Denali Ultimate 4WD with the 6.2-liter is more expensive, at $83,995. The AT4X rise pays for extra equipment. the standard AT4X inheriting parts from the Sierra ATVX AEV created in collaboration with American Expedition Vehicles. The extra gear includes a revised grille with gloss black and dark nickel trim, AEV front and rear bumpers with increased approach and departure angles, a hot-stamped hardened steel front skid plate inflate the cost and give the ATX4 a little more capability off-road. The equipment list narrows the gap from the regular AT4X to the AT4X AEV, the latter going just a bit further with four more skid plates, AEV's Salta wheels, and a smattering of black trim around the body. The surprise is that the configurator lists the AT4X AEV as a package for the AT4X, not as a separate trim, which is what we were looking for. That package costs $6,895, putting the MSRP at $90,490 after the $1,895 destination charge.  Unlike some other spendy trucks that can be optioned with another 10% or 15% of their MSRPs in options, there's not much left on the menu for the Sierra AT4X AEV. The most expensive substantial change would be paint, which costs at least $495 for anything but Summit White. There are no other wheel choices, no other interior choices than Obsidian Rush full leather. Checking the boxes for equipment like the console-mounted safe, off-road high-clearance steps, and hard-folding tonneau cover, plus a fancy metallic paint, comes to $3,650 for the bundle. Make it $95,000 before dealer fees and add-ons for Chevy's trail-focused truck. That's about midway between the hi-po high-speed desert runners, the $78,600 Ford Raptor and the $109,600 Raptor R, and $4,300 more than a base Ram TRX, a truck with three $10,000 option packages. It costs a lot more to get dirty than it used to. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
