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 shows crisp sense of style in leaked images

You're looking at the 2016 Cadillac CT6, aided by the almost inevitable internet-aided leak, ahead of its debut at the New York Auto Show this week. As you can see, the overall shape is straight-edged and aggressive, and overall in keeping with what we've seen from Cadillac over the last several years. High-tech lighting clusters extend from the fender peaks all the way down in what appear to be LED strips toward the lower fascia and its rectangular fog lights. A suitably massive grille encrusted in chrome boasts one of the larger Wreath and Crest badges we've ever witnessed on a car. Under that sharply creased hood will sit a twin-turbo 3.0-liter V6 engine with 400 horsepower at its disposal, according to Cadillac, mated to an eight-speed automatic transmission. A naturally aspirated 3.6-liter V6 will also be available, we're told. We may wish for an edgier range-topping sedan from Cadillac, but it's not really fair to draw any real conclusions from just one leaked image. In other words, stay tuned, 'cause the rest of the story won't be far behind.

Cadillac may not build Elmiraj coupe

Despite the fact that most everyone who has laid eyes on the Cadillac Elmiraj concept coupe loves it, General Motors insiders are still trying to prove the business case to build the car. And it's certainly not a guarantee.
"I want to see this car go into production badly. Very badly," Ed Welburn, GM's Global Head of Design, told Autoblog. But the Cadillac design studio is busier than it's ever been before, and the company is working on prioritizing which cars deserve to get the billion-dollar price tag needed to research and develop a new model.
No matter what happens, Welburn says the car has made its mark on Cadillac
