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.

2016 Cadillac CT6 has arrived

We have known for a while that the 2015 New York Auto Show would mark the debut of Cadillac's latest flagship model. But after months of waiting as Caddy slowly revealed details, the 2016 Cadillac CT6 has finally arrived. The sedan is a technological tour de force for the brand and inaugurates a long list of new technologies. The CT6 will begin production at the Detroit-Hamtramck Assembly plant in late 2015 and will go on sale with three engine options. Caddy won't release final figures yet, but based on preliminary numbers, we know the base 2.0-liter turbocharged four-cylinder will make 265 horsepower. Stepping up to the newly revised 3.6-liter V6 will net buyers an estimated 335 hp, and finally there will be the 3.0-liter twin-turbo V6 with an output of around 400 hp. All of these engines will be mated to eight-speed automatic transmissions, and six-cylinder models will get standard all-wheel drive that will be able to constantly vary the power sent to the front wheels. Carrying those powertrains is the new, aluminum-intensive Omega architecture. In addition to the lightweight metal making up the platform, the entire exterior also uses it to provide an estimated curb weight of less than 3,700 pounds. The decision to shed mass makes the CT6 a featherweight in its class – for comparison, the lightest, six-cylinder Audi A8 weighs 4,365 pounds. The sedan rides on a 122.4-inch wheelbase and is 204 inches long. That makes the Cadillac about 1.3 inches shorter than the smallest BMW 7 Series, but the Caddy is projected to tip the scales at less than both the big Bimmer and even the 5 Series, too. Cadillac wants the CT6 to be a luxury sedan that drivers can enjoy. In addition to the low weight, there's an available Active Chassis System throughout the range with rear-wheel steering and Magnetic Ride Control. When combined with the all-wheel-drive system, it means every corner of the car is both driving and steering the vehicle. Inside, the CT6 offers a ton of tech and luxury. Drivers are held in massaging, leather seats, and rear passengers also get adjustable chairs that are heated and cooled. Quad-zone climate controls keep everyone comfortable. Plus, in addition to the 34-speaker Bose audio system and streaming rearview mirror, there are features like a 10.2-inch CUE infotainment system with a capacitive touchscreen and console-mounted touchpad. The display also shows a 360-degree view outside and can even record video when the security system is activated.

Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.
