As GM Authority reported back in May 2023, General Motors was hit with a Canadian class action lawsuit related to the 8LXX eight-speed automatic transmission found in a plethora of GM vehicles. Now, another similar lawsuit has been filed in Quebec, Canada.
According to a report from Car Complaints, the lawsuit alleges that affected transmissions have a tendency to shudder, jerk, shift hard, shake and hesitate. The plaintiff claims that these issues are dangerous because the affected vehicles have the potential to suddenly decelerate while driving and without warning.
The lawsuit stated that it included, “All the persons in Quebec (including but not limited to individuals, corporations, and estates) who, prior to the date of authorization of this action as a class action, bought or leased vehicles (new or used) designed, manufactured, marketed, distributed, sold, warranted, or serviced by GM and equipped with GM’s Hydra-Matic 8L90 transmission or Hydra-Matic 8L45 transmission.”
The lawsuit lists a wide range of GM vehicles equipped with affected transmissions, including:
- 2015 – 2019 Chevy Corvette
- 2015 – 2023 Chevy Colorado
- 2015 – 2023 Chevy Silverado
- 2016 – 2023 Chevy Camaro
- 2017 – 2023 Chevy Express (4.3L LV1 V6 and 2.8L LWN I4)
- 2015 – 2017 GMC Yukon Denali XL
- 2015 – 2019 GMC Canyon
- 2015 – 2019 GMC Sierra
- 2017 – 2023 GMC Savana (4.3L LV1 V6 and 2.8L LWN I4)
- 2015 – 2017 Cadillac Escalade
- 2016 – 2023 Cadillac ATS-V
- 2016 – 2023 Cadillac CTS-V
- 2016 – 2023 Cadillac CT6
For those who may be unaware, GM Authority has covered the various class-action lawsuits filed against General Motors over the past few years. In fact, we’ve even gone so far as to call on the Detroit-based automaker to address the purported problems in an op-ed published back in 2019. Looking forward, many GM vehicles have replaced the eight-speed transmission with the newer GM 10-speed that was co-developed with Ford. However, it’s worth noting that certain models like the Camaro, Colorado and Silverado still use this transmission in certain applications.
