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.

The future's electric — but the present is peak gasoline. Burn some rubber! Do donuts!

I vividly remember the year 1993 as a teenager looking forward to getting my driver’s license, longingly staring into Pontiac dealerships at every opportunity for a chance to see the brand-new fourth-generation Firebird and Trans Am. Back then, 275 horsepower, courtesy of GMÂ’s LT1 5.7-liter V8 engine, was breathtaking. A few years later, when Ram Air induction systems freed up enough fresh air to boost power over 300 ponies, I figured we were right back where my fatherÂ’s generation left off when the seminal muscle car era ended around the year 1974. It couldn't get any better than that. I was wrong. Horsepower continued climbing, prices remained within reach of the average new-car buyer looking for cheap performance, and a whole new level of muscular magnitude continued widening eyes of automotive enthusiasts all across the United States. It was all ushered in by cheap gasoline prices. And as much as petrolheads bemoan the coming wave of electric vehicles, perhaps instead now would be a good time for critics to sit back and enjoy the current and likely final wave of internal combustion. Today, itÂ’s easier than ever to park an overpowered rear-wheel-drive super coupe or sedan in your driveway. Your nearest Chevy dealership will happily sell you a Camaro with as much as 650 horsepower. Not enough? Take a gander at the Ford showroom and youÂ’ll find a herd of Mustangs up to 760 ponies. Or if nothing but the most powerful will do, waltz on over to the truly combustion-obsessed sales team of a Dodge dealer and relish in the glory of a 797-hp Charger or 807-hp Challenger. Want some more luxury to go with your overgrown stable of horses? Try Cadillac, where you'll find a 668-horsepower CT5-V Blackwing. You could instead choose to wrap that huffin' and chuggin' V8 in an SUV. Or go really off the rails and buy a Ram TRX or Jeep Wrangler Rubicon 392 and hit the dunes after a quick stop at the drag strip. Go pump some gas. Burn a little rubber. Do donuts! There is nothing but your pocketbook keeping you from buying the V8-powered car of your dreams. Yes, just about every major automaker in the world has halted development of future internal combustion engines in favor of gaining expertise in batteries and electric motors. No, that doesnÂ’t mean that gasoline is going extinct. There are going to be gas stations dotting American cities and highways for the rest of our lifetimes.

2015 Cadillac ATS-V gunning for the BMW M3

Spy photographers have spotted something interesting. Cadillac engineers have taken to public streets with the upcoming ATS-V and a playmate: the current BMW M3 Sedan. The prototype seen here wears a more aggressive front fascia, flared fenders and beefy brakes. Quad exhaust tips and what looks to be a small lip spoiler on the trunk deck sum up the most obvious visual changes over the standard ATS outside. Word has it the ATS-V will bow with the same twin-turbo 3.6-liter V6 available in the nose of the XTS. In that application, the engine is good for a stout 410 horsepower, which should be more than enough to hustle the sedan around a track.
Other details are still murky, however. First and foremost: will GM offer the ATS-V with an honest manual transmission, like it does with its big brother, the CTS-V? Something tells us we won't have long to wait to find out - the machine will likely bow next year as a 2015 model. Until then, dig in on our newest bevy of spy photos.
