GM must face big class action over faulty transmissions

Includes 800,000 vehicles: Here are the models involved

SEPTEMBER 2024 — autoblog.com — General Motors (GM) was ordered by a federal appeals court to face a class action claiming it violated laws of 26 U.S. states by knowingly selling several hundred thousand cars, trucks and SUVs with faulty transmissions.

The 6th U.S. Circuit Court of Appeals said a lower court judge had discretion to let drivers sue in groups over Cadillac, Chevrolet and GMC vehicles equipped with 8L45 or 8L90 eight-speed automatic transmissions, and sold in the 2015 through 2019 model years.

Drivers said the vehicles shudder and shake in higher gears, and hesitate and lurch in lower gears, even after repair attempts. They also accused GM of telling dealers to provide assurance that harsh shifts were “normal.”…..The GM litigation covers about 800,000 vehicles, including 514,000 in the certified classes.

Vehicles include the Cadillac CTS, CT6 and Escalade; Chevrolet Camaro, Colorado, Corvette and Silverado; and GMC Canyon, Sierra and Yukon, among others.
