GM cadillac escaladeA class action lawsuit filed against General Motors claims that transmissions in Chevy and Cadillac vehicles possess a defect that cause them to jolt and shake violently.

The GM class action lawsuit was filed by Marisella Gutierrez, Jimmy Harman, Mark Kidd, and James Norvell who say they own GM vehicles that possess this problem, and have had to have repairs done under warranty.

However, the four vehicle owners fear that their warranty will no longer cover repairs for the problem.

The GM transmission class action lawsuit claims that certain Cadillac and Chevy vehicles are fitted with a Hydra-Matic 8L90 or 8L45 transmission that cause them to jolt, lurch, and jerk while being driven.

The Chevy, Cadillac class action lawsuit goes on to say that the allegedly defective transmissions not only cause an unpleasant driving experience, but cause the vehicles to fail to accelerate, fail to downshift, and delay stopping even if the brakes are applied.

The GM class action lawsuit claims that these problems pose serious dangers because they can prevent the drivers from being able to operate their vehicles effectively, which can lead to a collision or an unsafe driving condition.

Allegedly, this problem is caused because of a range of internal problems in the transmissions, including defective torque converters. The plaintiffs state that there is too much friction between the transmission component parts, which results in metal shavings coming off from the elements.

These metal shavings allegedly then circulate throughout the transmissions’ hydraulic systems, causing further damage to the transmission’s hydraulic systems.

The drivers say GM has been aware of this defect for years, and has failed to adequately address the issue. According to the customers, the company has even tried to convince customers that the problems were normal, including the dramatic “surging” or “unexpected acceleration” that are characteristics of the defect.

The Chevy, Cadillac transmissions class action lawsuit states that customers were financially injured by the transmission defect and by GM’s denial of it. Allegedly, had customers been aware of the defect before they purchased or leased their vehicles, they would not have purchased them or would not have paid as much as they did for it.

The consumers argue that GM is aware of or should have been aware of the defect, noting that numerous trade publications criticized the transmissions problem. Despite this criticism, GM has reportedly never truly fixed the problem, and continues to make money from the sale of the vehicles while consumers continue to be financially injured and be put at risk physically.

Allegedly, GM has not attempted to remedy the problem in a widespread way, and has only offered solutions like patchwork software updates, parts replacements, and other insufficient fixes.

The GM drivers are represented by Lynn Lincoln Sarko, Gretchen Freeman Cappio, Tana Lin, Ryan McDevitt, and Max Goins of Keller Rohrback LLP.

The GM Chevy Cadillac Transmission Defect Class Action Lawsuit is Marisella Gutierrez, et al. v. General Motors LLC, Case No. 2:19-cv-12371-GCS-SDD, in the U.S. District Court for the Eastern District of Michigan.

    My son recently purchased a 2018 Chevy equinox with 16K miles in oct 2023 from a local person as part of estate sale. The car has the 9speed 9T50 and dealer says metal from converter in the transmission and out of warranty. I don’t believe this should have occurred with low mileage.

    I have had transmissions issues with this vehicle I think due to bad torque converter. I have multiple videos showing the issue and an audio recording from service manager with Cadillac. My vehicle is a 2016 Cadillac ATS I am willing to share videos to help case. I have tried to get this fixed over 5 times and dealer would not fix it. I have recorded conversation of Cadillac rep admitting to what the problem is and he said the company won’t pay to fix it because it cost too much.

  7. Jennifer says:
