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 Lyriq EV debut delayed by Covid-19 virus

The, coronavirus, otherwise dubbed Covid-19, has claimed another large gathering. General Motors canceled the public debut of its coming Cadillac Lyriq crossover, planned for April 2 in Los Angeles, due to fears over the continued spread of the virus. With more than 14 confirmed cases of residents with Covid-19, Los Angeles declared a state of emergency last week. Michael Albano, a communications director at GM, said in an e-mail to The Verge that "Our top priority is the safety of our media guests and employees." At the time of writing there's no word on a potential new date for the reveal for the highly anticipated crossover that GM just announced last week at a private event in Warren, Michigan. However, the automaker provided Autoblog with a statement that read, in part, "Please know we are working to reschedule the reveal as soon as possible." What we know about the Lyriq is just as compelling as what we don't know. There XT5-sized people hauler will be out to dazzle in every way, with a ton of weight on its shoulders — many will be judging GM's and Cadillac's past and claimed preparedness for the future based on this one offering. The Lyriq will be the first GM EV to sit on a new EV architecture the engineers call BEV3 and the marketers call Ultium, with battery capacities up to 200 kWh and a potential range of 400 miles. Speaking of which, GM just applied to trademark the term Tecra with the US Patent and Trademark Office, so we could be in for more information on innovative battery systems in the not-too-distant future. The automaker could forgo a public debut for the time being and opt to livestream the event. Or, who knows, it's possible the Detroit Auto Show just garnered itself a whopping debut for the show's debut event in June; the first rendering of the Lyriq aired at last year's Detroit show.

2020 Cadillac XT4 Review and Buying Guide | Competence and curb appeal

The 2020 Cadillac XT4 is a handsome little crossover distinctively sized between two segments. This allows it to boast backseat space on par with larger SUVs like the Audi Q5, while being a bit more park-able and fuel efficient like the BMW X1. There should definitely be a Goldilocks "just right" thing going on for many shoppers. Cadillac's baby SUV also impresses on the technology front, boasting loads of standard, advanced features along with a user-friendly touchscreen interface that shouldn't be too hard to figure out. There are dynamic missteps, though. The steering, throttle and brake pedals lack the driver-oriented response and feedback we've come to expect from Cadillac's sharply tuned sport sedans, while also not exactly possessing the nice-and-easy isolation of Caddy's past. In either scenario, we're not sure it "drives like a Cadillac" despite some otherwise impressive engineering going on underneath that handsome skin. The XT4 is also pretty expensive given its features, size and interior quality. Competitors both larger (Acura RDX) and smaller (Volvo XC40) provide better value. Still, as we noted in our XT4 first drive, there's enough novel tech to provide bragging rights, it's obviously a Cadillac in design (and definitely not just a rebadged Chevrolet in execution), and it's a pleasing enough place to sit while scooting around in traffic. It has competence and curb appeal, which count for a lot. What's new for 2020? After being an all-new model last year, the XT4 heads into 2020 with some noteworthy features updates: Forward collision warning and automatic emergency braking are now standard, while the Premium Luxury trim level gets the hands-free power liftgate as standard equipment.   What's the XT4's interior and in-car technology like? The XT4's interior design isn't as memorable as that of its exterior, nor its stylish Volvo XC40 and Lincoln Corsair competitors. It's a bit generic, which just doesn't seem right for a Cadillac. Materials quality is acceptable when closer to its base price, but begins feeling less so as options are added and the price tag rises. We've also driven multiple XT4's with an annoying rattle in the B pillar. Standard infotainment technology is abundant. Apple CarPlay and Android Auto are included with the standard 8-inch touchscreen and benefit from a pair of USB ports: one standard USB-A and the other a newer USB-C.
