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.

2021 Cadillac CT4 Review | A joy to drive, a puzzle to compare

Cadillac's smallest sedan is arguably its most competitive. The question is, though, what does the 2021 Cadillac CT4 actually compete with? It has the price tag and interior in keeping with the growing number of sub-compact luxury sedans, yet its rear-drive layout and sophisticated chassis are more akin to sedans that are a size up. It sure drives more like a BMW 3 Series than something smaller and cheaper. Actually, it could easily be argued that the CT4 is a more rewarding sport sedan than BMW's benchmark – be it the Premium Luxury you see above or spicier CT4-V trim.  That's where the comparison ends, however. The CT4 is smaller, with a cramped back seat and rinky-dink trunk. Its cabin quality is lower and its engines less refined. Yet, it is sufficiently cheaper to justify all of the above. For the dwindling few who still prize communicative steering and an unflappable suspension in their entry-level luxury sedan, the CT4 is a terrific choice – no matter what you compare it to. What's new for 2021? The CT4 was all-new last year, so there are only minor updates for '21. A 12-inch HD instrument cluster is now available as part of the Technology package in top trim levels, while Cadillac's Super Cruise semi-autonomous driver assist system will be a late-availability option. Wirelessly connected Apple CarPlay and Android Auto are now standard. There's also a new Diamond Sky Special Edition that adds a unique color scheme and trim finishes.  What's the CT4 interior and in-car technology like? We've criticized the design and quality of other Cadillac interiors, and although the CT4's is awfully similar to those, its lower price and market positioning make it far more competitive and, well, palatable. It may not be as expressive as the Mercedes A- or CLA-classes, but for the money, we don't think you'll be disappointed. The infotainment system is controlled by an 8-inch touchscreen with a pair of redundant control knobs better suited to scrolling through playlists, radio stations or other menu functions. One is adjacent to the screen and volume knob, while the bigger one is on the center console. We like this setup quite a bit and appreciate the Cadillac's system's clean look and quick responses. The base setup includes wirelessly connected Android Auto and Apple CarPlay, plus Amazon Alexa integration and a choice of USB Type-A and Type-C charging.

The Cadillac CT6 Plug-In is now available in China. The luxury plug-in hybrid sedan uses a turbocharged 2.0-liter engine plus two electric motors, which give the car a 0-62 mph time of 5.4 seconds.

Two Oregon utilities are launching a program to increase EV adoption. Portland General Electric (PGE) will build six charging locations, each with up to four dual-standard fast chargers. PGE will also build and operate charging sites for electric buses, freeing up money for Portland's TriMet transit agency to spend on the actual buses. Pacific Power will also build public EV chargers, and lower some electricity rates for operators. Both companies will also work to inform the public about the benefits of electric mobility. Oregon utilities are required to stop using coal by 2030, and use 50 percent renewable energy by 2040, which will make EVs even cleaner. Read more at Green Car Reports. Continental says a shift to EVs will cost its company jobs. The automotive parts supplier's CEO, Elmar Degenhart, says that while the company will need to cut production jobs, those will be offset at least in part by the creation of new positions related to electric mobility. "There is enough time to design the process such that the blow is softened and major pain can be avoided," says Degenhart. Some 30,000 jobs at Continental are tied to combustion engines.
