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.

GM looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

Hummer teases crab mode, reveal set for Oct. 20

DETROIT — GMC confirmed it will reveal the Hummer electric off-roader Oct. 20 and released a video teasing the vehicleÂ’s so-called crab mode. Crab mode allows the Hummer to move diagonally and is enabled by the vehicleÂ’s four-wheel steering. The video shows tires, and well, a crab. “When you're in the really difficult terrain, this just gives you unparalleled maneuverability,” said Duncan Aldred, global vice president of Buick GMC. The Hummer will be offered as truck and SUV models, and customers will be able to make reservations beginning on the reveal date. Deliveries are expected to begin in fall 2021. The Hummer was supposed to be revealed May 20, but was delayed due to the Covid-19 pandemic. The Hummer was teased in a Super Bowl ad this year with NBA superstar LeBron James, who is the vehicle's frontman. It will have several EV powertrains which General Motors calls Ultium, and the most capable variant will have an estimated 1,000 hp and hit 60 mph in three seconds. The Hummer will also offer removable roof panels. “This is very much going to be a luxury vehicle which competes against a broad spectrum,” Aldred said Monday on a conference call with reporters. The Hummer will take aim against a variety of vehicles, including the four-door Bronco, RivianÂ’s truck and SUV and the Jeep Wrangler 4xe. Aldred is optimistic the return of the Hummer name will help GMC carve its niche in this growing segment of trucks and SUVs with varying degrees of electric propulsion and off-road capability. GM sold vehicles under the Hummer brand from 1992-2010, before scrapping it in the wake of GMÂ’s historic 2009 bankruptcy and restructuring. Hummer is relaunching under the GMC umbrella. “ItÂ’s real desirability, itÂ’s almost cult-like status,” Aldred said. “I think a huge amount of people are going to have interest in this.” GM, which is re-emphasizing its defense division, could also repurpose the Hummer for military use, perhaps as transport vehicles. Hummers are descended from the Humvee, which is still used by U.S. forces.
