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.

IIHS: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.

GM SUV window switch recall urges owners to park vehicles outside

It's not unusual for there to be a lag between an automaker announcing a recall and the official documentation showing up on the National Highway Traffic Safety Administration website. So it's no surprise that a recent GM campaign took about a month to appear in its official capacity. However, there appears to be some big differences between the two reports with potential safety implications.
In late June, GM announced that it needed to recall 181,984 examples of the Chevrolet Trailblazer, Buick Rainier, GMC Envoy, Isuzu Ascender and Saab 9-7x from the 2005-2007 model years, plus the 2006 Chevy Trailblazer EXT and 2006 GMC Envoy XL. The new documents paint a slightly different picture with 184,611 needing repaired and different model years listed.
The reason for the fix is still the same, though. It's possible for fluid to contact the master power window switch module in the driver's door, which can corrode the part. Eventually this could cause a short circuit, leaving the buttons inoperable and potentially leading to a fire. But the new NHTSA documents add an important note: "A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made."
