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 gives enthusiasts an early look at its next high-performance sedans

Cadillac will introduce a pair of sport sedans named CT4-V Blackwing and CT5-V Blackwing, respectively, at 7 p.m. Eastern today (February 1). While car companies routinely drum up excitement for new models by releasing tightly-cropped or blacked-out images, Cadillac surprised us with a photo, and a TV spot that aired during the Rolex 24 at Daytona, that shows both cars in their entirety. Somewhat confusingly, the CT4-V and the CT5-V are not direct replacements for the ATS-V and the CTS-V; they're mid-range models, and they're powered, equipped, and priced accordingly. It's these flagship Blackwing variants that will pick up where the last-generation Vs left off with a significant bump in power, numerous chassis tweaks, and a more aggressive-looking design. They'll arrive in showrooms in time for the 2022 model year. Blackwing drivers won't draw unnecessary attention to themselves, because the visual changes are relatively subtle. Riding on model-specific wheels, the CT4-V Blackwing gains bigger air intakes on the front end, vents punched into the fenders, and a low-key body kit that adds a front splitter, front winglets, and a trunk-mounted spoiler. Cadillac gave the CT5-V a similar treatment, and it mounted the rear wheels on surprisingly wide tires. Cadillac pointed out the Blackwing sedans benefit from the world's fastest-reacting suspension system. It's likely the fourth evolution of its magnetic ride control technology, which it detailed in October 2020.  While full specifications remain under wraps until the duo's unveiling, we know that both sedans will be available with a six-speed manual transmission. It's reasonable to assume that an automatic (likely the familiar 10-speed) will be offered as well. As for what's under the hood, our crystal ball tells us that the CT5-V will land with a V8 engine, though it won't be the short-lived twin-turbocharged Blackwing unit that gave both cars their name. Enginers might have selected an evolution of the CTS-V's 6.2-liter. As for the CT4-V, it will receive the ATS-V's 3.6-liter turbocharged V6. Both models will be exclusively available with rear-wheel-drive. Enthusiasts who want to secure an early built slot will have the chance to reserve a 2022 CT4-V Blackwing or a 2022 CT5-V Blackwing by visiting Cadillac's website shortly after the sedans are unveiled on February 1. As we previously reported, the first 250 units of each car will wear a numbered plaque on the steering wheel.

GM CEO Mary Barra predicts mass electrification will take decades

General Motors is allocating a substantial amount of money to the development of electric technology, but Mary Barra, the firm's CEO, conceded that battery-powered cars won't fully replace their gasoline-burning counterparts for several decades. She stressed the shift is ongoing, but she hinted it will be slower than many assume. "We believe the transition will happen over time," affirmed Barra on "Leadership Live with David Rubenstein," a talk show aired by Bloomberg Television. She added that not every car will be electric in 2040. "It will happen in a little bit longer period, but it will happen," she told the host. She was presumably talking about the United States market; the situation is markedly different in Europe and in China, where strict government regulations (and even stricter ones on the horizon) are accelerating the shift towards electric cars. On the surface, it doesn't look like General Motors has much invested in electrification; the only battery-powered model it sells in America in 2020 is the Chevrolet Bolt (pictured), which undeniably remains a niche vehicle. Sales totaled 16,418 units in 2019, meaning the Corvette beat it by about 1,500 sales. In comparison, Cadillac sold 35,424 examples of the aging last-generation Escalade during the same time period. And yet, the company isn't giving up. It has numerous electric models in the pipeline including a slightly larger version of the aforementioned Bolt, the much-hyped GMC Hummer pickup, and an electric crossover assigned to the Cadillac brand. These models (and others) will use the Ultium battery technology that General Motors is currently developing. Its engineers are also working on a modular platform capable of underpinning a wide variety of cars. Bringing these innovations to the market is a Herculean task. EVs may not take over for decades, but Barra and her team must believe their 2% market share will increase significantly in the coming years if they're approving these programs. Autonomous technology is even costlier, more complicated, and more time-consuming to develop. Barra nonetheless expects to see the first General Motors-built driverless vehicles on the road by 2025. "I definitely think it will happen within the next five years. Our Cruise team is continuing to develop technology so it's safer than a human driver. I think you'll see it clearly within five years," she said on the same talk show. Her statement is vague but realistic.
