GM 8-speed transmission lawsuit granted class action certification

A story on Autoblog about potentially faulty 8-speed automatic transmissions from General Motors in 2019 has, as of the day this was published, 166 comments, mostly from owners of cars and trucks who say they are experiencing "a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." At the time, lawyers were seeking statewide classes in at least six states. As of today, the Detroit Free Press reports that a judge has granted class action status to a lawsuit brought by 39 plaintiffs across 26 states covering the transmission issue. The lawsuit specifically applies to vehicles that are equipped with GM's 8L90 or 8L45 8-speed automatic transmissions made between 2015 and March 1, 2019. Both of these transmissions are similar units, the 8L45 being slightly lighter version used in fewer vehicles than the beefier 8L90, and are designed for front-engine, rear- or all-wheel drive applications. The lawsuit alleges that the erratic transmission behavior makes some vehicles unsafe to drive. Ted Leopold, partner at Cohen Milstein and the court-appointed lead counsel for the case, said in a statement, "General Motors knowingly sold over 800,000 eight-speed transmission vehicles, which they knew to be defective for years, and yet made the business decision not to tell its customers before purchase." He added, "Dealers were directed to tell the customers that harsh shifts were ‘normal' or ‘characteristic.Â’ Such decision making is both highly irresponsible and emblematic of what GM believes it can get away with." The vehicles included in the court order with potentially faulty transmissions includes: 2015-2019 Chevrolet Silverado 2017-2019 Chevrolet Colorado 2015-2019 Chevrolet Corvette 2016-2019 Chevrolet Camaro 2015-2019 Cadillac Escalade and Escalade ESV 2016-2019 Cadillac ATS, ATS-V, CTS, CT6, and CTS-V 2015-2019 GMC Sierra, Yukon, Yukon XL, and Yukon Denali XL 2017-2019 GMC Canyon Some additional details of the lawsuit can be found at the Cohen Milstein site, including claims that "since 2015, GM has issued thirteen versions of a “technical service bulletin,” or “TSB,” related to this shifting issue alone." The statement from Cohen Milstein says that a "second action regarding GM vehicles with 8L transmissions is also underway in Battle v. General Motors, LLC, 2:22-cv-108783.

"Turbo" Chevrolet Camaro is a 700-HP fantasy car come to life [w/video]

For a concept car built to promote an animated movie about a snail that wants to go racing, this thing ain't half bad. The outsized monster you see before you started life as a Chevrolet Camaro ZL1, and then went through a big-time Hollywood makeover before being positioned on the Chevrolet stand here in Chicago.
This 2013 "Turbo" Camaro Coupe is getting the promotion machine ratcheted up for a new DreamWorks tale by the name of, you guessed it, Turbo. Coming this summer, the movie will follow one snail's quest to become a race driver worthy of making the cut at the Indy 500. Like many DreamWorks vehicles before it, we're guessing that the petrolhead snail will star in a movie that adults (especially racing fans) with have no trouble watching with their kids. Check out the trailer below to see if you agree.
As for the car, we're told that it is "instrumental" in transforming Turbo from snail into racer. Helping the beastly pony car in this mighty task, is an ankle-cracking front splitter matched by a ungodly huge rear wing out back, a COPO hood and a supercharged (yes, supercharged) V8 engine making more than 700 horsepower. 24-inch wheels all the way around - 10-inches wide in front and 15-inches wide in back - should allow the "Turbo" Camaro to hook up with ease, as well.

A Chevy Camaro hybrid? That's what EcoCAR3 could bring

Figuring out a way for a hybrid powertrain to co-exist with the performance expectations of a classic American muscle car is a challenge that could vex that most experienced of automotive engineers. It's a challenge, in fact, being handed to a bunch of college students. Over the next four years, students from 16 North American colleges and universities will attempt to wring fuel efficiency from a 2016 Chevy Camaro as part of EcoCAR3, an advanced-vehicle technology competition sponsored by the Department of Energy, General Motors and others. They'll be attempting to use hybrid or plug-in hybrid technology while not sacrificing the performance of the Camaro, which was selected in part because the current model achieves just 17 miles per gallon in city driving and 28 MPGs on the highway, per EPA numbers. Students will get the latest version of the vehicle to work on, one that is expected to be unveiled next month on Belle Isle in Detroit. "If we still want to produce V8 Camaros, we're going to have to look at alternative methods of propulsion," said Al Oppenheiser, the chief engineer on the Camaro. "So the ideas that these college teams come up with could very easily be adapted to a car like the Camaro." Unlike similar competitions that reward fuel efficiency in vehicles, EcoCAR seeks those gains while emphasizing cost and consumer acceptance of these vehicles. The cars shouldn't look like experiments; they should look like everyday vehicles on the road. Previous competitions have allowed the teams to use whatever powertrain they desired. This time, EcoCAR officials designed the competition to concentrate on hybrid, hybrid-electric and diesel options. Competitors won't have the option of using hydrogen fuel cells as they have in the past. Last year, a team from Colorado State built a vehicle that contained both hydrogen and electric power sources. This year's limit is a curious choice, as some automakers such as Toyota have placed heavy bets on fuel cells in recent years. General Motors also runs a fuel-cell program. With the focus on cost and practicality, however, the program officials wanted to narrow the framework of the contest. "We always have some good decisions on what to make within the scope or out of scope," said Jim Kolhoff, global director of software engineering for General Motors.
