GM is facing another class-action lawsuit related to the performance of its 8LXX eight-speed automatic transmission.
This latest lawsuit was filed in U.S. District Court for the Eastern District of Michigan and involves 2019 to 2022 model year Chevy, GMC and Cadillac vehicles that were purchased after March 1st, 2019, according to Car Complaints. Plaintiffs claim the 8LXX transmissions in their GM vehicles are prone to jerking, hesitation, surging and lurching while the vehicle is in operation and that GM has been aware of these alleged issues since as early as 2013.
Plaintiffs in this suit say GM has also worked to actively cover up the alleged problems and won’t honor past warranty agreements, despite the transmissions being covered by the automaker’s express warranty. Fine print in the warranty indicates GM’s warranty covers all manufacturing defects except for those related to “slight noise, vibrations, or other normal characteristics of the vehicle due to materials or workmanship occurring during the warranty period.”
This lawsuit applies to owners of the following GM products who purchased their vehicle before March 1st, 2021:
- 2019-2022 Chevrolet Camaro
- 2019-2022 Chevrolet Colorado
- 2019-2022 Chevrolet Silverado
- 2019 Chevrolet Corvette
- 2019 Cadillac ATS
- 2019 Cadillac ATS-V
- 2019 Cadillac CTS
- 2019 Cadillac CT6
- 2019 Cadillac CTS-V
- 2019-2022 GMC Canyon
- 2019-2022 GMC Sierra
Numerous class-action suits have been filed against GM over its 8L45E and 8L90 eight-speed automatic transmissions in recent years. GM Authority has covered these reported issues with the GM eight-speed transmission extensively and even called on GM to address the purported problems in an op-ed published back in 2019. Some GM vehicles have ditched the eight-speed transmission in favor of the newer GM 10-speed it co-developed with Ford, however certain models still use this transmission, like the 2022 Chevy Camaro, Colorado and Silverado, for example.
Four plaintiffs are named in this lawsuit, including three individuals that own a 2020 or 2021 model year GMC Canyon and two separate owners of a 2021 GMC Sierra 1500 and 2021 Chevy Silverado 1500.
