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.

GM tells NHTSA pickup truck electronic glitch is 'inconsequential'

General Motors has been enduring some serious problems with recalls recently, and it is hoping to avoid launching another major safety campaign. 200,921 2014 Chevrolet Silverado and GMC Sierra pickups are under the microscope due to a rare problem with their instruments, an issue GM calls calls "inconsequential to motor vehicle safety." The Detroit-based automaker believes that the glitch is so minor that it has filed a petition with the National Highway Traffic Safety Administration asking the government safety watchdog for permission to pass on recalling the vehicles.
The fault at issue can occasionally cause the instrument cluster to reset when drivers use the steering wheel controls to browse songs from an external media device connected to the truck's USB ports. If a song's title information exceeds 2,000 bytes, according to The Detroit News, then the instrument panel can reset, which in turn causes the gauges, shift position indicator and cruise control telltale to turn off briefly. When rebooting, other instrument panel lights may briefly illuminate without their functions actually being activated. GM claims that if this does happen, the instrument display lights go out for about 1.5 seconds and the bulb check lasts a further five seconds. However, this snafu has no actual affect on the truck's operation. The glitch is present in trucks built between January 29, 2013, and October 28, 2013.

GMC caught using Rivian R1T image for Sierra Denali EV Photoshop

The rise of electric start-ups have many legacy automakers checking their rear view mirrors as they scramble to join the EV party. Most wouldn't like to admit it publicly, but we know that at least some folks at General Motors are keeping an eye on Rivian. That's because a recent post on social media account by the General Motors design department appears to have used an image of the Rivian R1T, but heavily photoshopped. The post was intended as a peek of the GMC Sierra Denali EV's rear view. Eagle-eyed observers like AllCarNews soon noticed many familiar elements to the rendering, including the wheels and tires, mirrors and doors. Even the backgrounds are identical, including some leaves that the truck is kicking up. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Seen side by side, the two pickups' similarities don't end there. The Sierra EV is wider, but the cab's rear pillars and glass look the same as the Rivian's, just stretched horizontally. The rear bumper and its license plate cutout and reflectors on either side look a bit too close for comfort as well.  The post as since been deleted. A GM spokesperson explained the situation to The Drive, "The GM Design Instagram channel is meant to give followers an inside look at the process of designing new products and the creative teams behind it. Often, these posts use sketches made for internal studio use during design development. The sketch in question was intended for internal use only, and was posted without the necessary approval. It has been removed from the GM Design Instagram page." Automakers often use products from the competition as benchmarks or design inspiration. Designers sometimes use existing images as a starting point as well, in order to quickly get an idea down "on paper". They just tend to do it in private. A juggernaut like GM using an image from an upstart like Rivian is embarrassing for the General, but surely an ego boost for the EV brand.  When dealing with an up-and-comer, perhaps it's best to take a page from Mad Men's Don Draper. In season four of the advertising drama, a newspaper calls the hot shot exec for a quote, after a young rival publicly says he's gunning for Draper. Draper knows exactly who the reporter is talking about but when asked for comment says, "Never heard of him." Related Video This content is hosted by a third party.
