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.

Outrageous Thor24 semi truck to appear in the new season of 'Jay Leno's Garage'

Wednesday is Jay Leno's birthday, and CNBC used the occasion to announce the upcoming season of Jay Leno's Garage. In a new teaser video, Leno is seen with a stacked list of guests, some new, some repeats, as well as a wild gamut of vehicles, including the absolutely insane 24-cylinder, 3,424-horsepower Thor24.  The outrageous semi build, which sold at auction in Saudi Arabia earlier this year for a whopping $12 million (or $1 million per supercharger) will join the likes of the Tesla Cybertruck and a recliner on wheels on the upcoming season of Jay's series.  Thor24 View 24 Photos The formula for Jay Leno's Garage is simple, successful, and not changing anytime soon. He brings out a bunch of famous people, some of which are real enthusiasts, others who have more casual driving backgrounds, and they experience a vehicle together.

2015 Chevrolet Corvette Z06 [w/videos]

I think I was supposed to be back hours ago. Driving northwest on State Road 190 with a final destination deep in the heart of the Death Valley National Park, it occurs to me that I might have agreed to return after an hour or so, instead of the four I'll end up stealing, solo, in the new Z06. Somewhere in the combination of mountain vistas, arching, speed-hungry desert roads, and the sound of this titanic engine on a constant run up the rev ladder, I forgot everything I'd promised back at home base. The generous, civilized part of me worries for a moment that absconding with the new-best Corvette might have left one of my fellow journalists without a car. But the selfish part of me – the part largely in control of the rocket-launcher of a throttle under my right foot ­– says "screw it." I spent two days with the 2015 Chevy Corvette Z06, a monster of a sports car that will soon be dominating track days everywhere, and I never once was inclined to share it. Hurtling through the shattered stillness of the desert and pulling big Gs at Spring Mountain circuit, I never felt overly disposed to give up my seat. This Corvette, more than any I've yet driven, was deep enough to hold my attention; for two days, for two years, probably. With this Z06, the Corvette steps over the amazing-for-the-price category, and solidly into the best-cars-in-the-world zone. There are peripheral elements that remind me of its blue collar, Bowtie heritage, sure, but there's more that simply begs me to carry on driving... faster. Most casual car observers will be able to pick the 2015 Z06 out from its less aggressive Stingray brothers. Subtler hints include a new, more open grille, larger extractor on the taller hood and rather discreet badges on the flanks of the car. More outrageous is the finned spoiler on the rear trunk lid, and the widebody look offered from flared fenders – an extra 1.57 inches (40 millimeters) at their beefiest point. Even driving around performance-car-laden Pahrump, NV – loaded thanks to the very active community at the Spring Mountain racing resort – members of the local populace were turning heads, waving and generally noting the Z06 with approval when I drove through town. In Torch Red over black painted aluminum wheels, staggered at 19-inches in front and 20 at the back, the amped-up Z06 hits a new level of road presence for the C7.
