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.

Cadillac XTS to become Opel flagship sedan?

According to Auto-News.de, Opel is considering using Cadillac's all-new big sedan, the XTS, as the base for its new flagship car, which would likely carry the name Omega.
WorldCarFans.com speculates that Opel could use GM's 3.6-liter direct-injection V6 that generates 304 horsepower or, possibly, a 2.8-liter turbocharged six-cylinder engine that creates 321 horsepower to power the vehicle. The European automaker could even use a 195-horsepower turbocharged four-cylinder engine in this application - fine, since many of Europe's largest sedans are powered by smaller, more efficient engines.
Regardless of power, the Omega could arrive at dealerships by the end of 2013.

New Cadillac ELR ad more educational, less controversial than 'Poolside'

Cadillac's first TV commercial for its ELR plug-in hybrid, Poolside, was a smash hit, in that a lot of people saw and talked about it. The 60-second spot didn't say the car was a plug-in, took potshots at the work ethic of all non-Americans and has raked in over a million views on YouTube (you can add one more here). Caddy's new ELR video will get a lot less media attention, but that's exactly the point. Cadillac claims it was happy with the way actor Neil McDonough strutted his way into the controversial ELR discussion. This time around, though, the coupe gets promoted in a more traditional way: with information about the car and what it can do - you know, drive on electricity, capture braking energy into the battery, go further on gas power when needed, those kinds of things – courtesy of GM's executive chief engineer for electrified vehicles, Pam Fletcher. The tone of the video has not been changed because of the Poolside controversy. David Caldwell, manager of Cadillac communications, tells AutoblogGreen that the new video is not destined for TV and is completely different because it's meant for a different audience. "It doesn't have any direct relation to Poolside," he says. "TV advertising is not necessarily the heart of marketing something like the ELR. Notwithstanding the fact that we had a very thought-provoking ad [laughs]." "We definitely have a need to communicate what the ELR is" - Cadillac's David Caldwell The way you reach out to people via the web is different than the mass-media techniques used in spots like Poolside during big TV events (it aired during the Winter Olympics). The two video spots are different because you need to offer different information in different ways, for example having an ELR website as well as an iPad filled with ELR information at the dealership. For Cadillac, TV is "not going to be the predominant methodology," used to sell the ELR, Caldwell said, "the web is closer to what you need to do to reach people. We definitely have a need to communicate what the ELR is. It's not television advertising at all." Caldwell said a handful of other short videos similar to the new one will go live in the near future, showcasing design and powertrain aspects of the car. Keep an eye out for them – just don't look for them on TV. You can watch the new video below.
