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 recalls 51k Enclave, Traverse, Acadia crossovers over fuel gauge inaccuracy

With all eyes fixed on General Motors in the wake of the ignition recall debacle, the auto giant has been carefully calling in a wide array of vehicles to fix anything and everything that could prove problematic. Just the other day it issued two separate recalls - one concerning the Cadillac SRX and another its heavy-duty pickups - and now it is issuing another.
This time the vehicles in question are the Buick Enclave, Chevy Traverse and GMC Acadia, three fullsize crossovers based on GM's Lambda platform. In an estimated 51,640 units manufactured between March 26 and August 15, 2013, the engine control module has been found to incorrectly display the level of fuel in the tank.
As a result, owners are being notified to bring their vehicles in to their local dealers to have the ECU reflashed to fix the problem. View the full details in the announcement below from the National Highway Traffic Safety Administration.

Chevrolet Silverado reportedly getting the GMC Sierra's MultiPro tailgate

GMC reinvented the pickup tailgate when it added a six-way option named MultiPro to the current-generation Sierra it introduced in 2019. It kept this clever feature to itself as a way to differentiate the Sierra from the Chevrolet Silverado, but a recent report claims it will begin sharing it in the not-too-distant future. Enthusiast website GM Authority learned from anonymous sources familiar with Chevrolet's product plans that the Silverado will soon receive its own version of the MultiPro tailgate. It will be called either MultiFlex or Multi-Flex, a name Chevrolet has already trademarked, and it was initially scheduled to make its debut for the 2021 model year. Its arrival might be delayed until the 2022 model year due to the coronavirus pandemic, however. Chevrolet's Silverado and GMC's Sierra are nearly identical under the sheet metal, so adding the latter's six-way tailgate to the former will be a relatively straightforward and cost-effective process. Interestingly, GM Authority wrote engineers could add a seventh function to the tailgate, though it didn't reveal what they have in store. It's also not sure whether both trucks will get the new feature, or if it will exclusively be offered on the Chevrolet. 2022 will bring major updates to the Silverado and the Sierra, potentially including — as we've previously reported — an independent rear suspension. Interior upgrades will allegedly be part of the mid-cycle changes, too, but we still don't know if the Silverado will receive the tough carbon fiber cargo box available in the Sierra. In the meantime, motorists in the market for a Sierra will temporarily have fewer options to choose from. GMC has asked its dealers to stop taking orders for the regular- and double-cab variants of the truck, according to a separate report from GM Authority. Putting the slower-selling regular- and double-cab trucks on hiatus will allow dealers to build up their inventory of crew-cabs, which sell far better and are in relatively short supply. These restrictions will remain in effect until the 2021 model year, which starts on September 14 for double- and crew-cab models and on September 21 for regular-cab trucks. All three body styles will be available in 2021. Related Video:
