(April 25, 2024)
A group of 13 consumers claims certain transmissions in General Motors vehicles from the last decade are defective and can create unsafe driving conditions, according to a new GM transmission class action.
The plaintiffs say GMโs Hydra-Matic 8L90 and Hydra-Matic 8L45 transmissions manufactured between 2014 and March 2019 can cause vehicles to shudder, lurch forward or have delayed acceleration.
They allege the issues are caused by transmission fluid issues, which can allegedly cause the GM transmissions to fail to purge air properly from valve bodies. This, the class action argues, is the cause of the shudder, lurching and delayed acceleration, as well as overall poor shift quality.
GM class action: Automaker elected not to recall, replace defective transmissionsย
The GM transmission issues happen around the time the affected vehiclesโ warranties run out, the class action claims. The plaintiffs allege that GM covers fluid flushes for customers who complain about their transmissions during the warranty period, without fixing the underlying issues.
GM engineers asked the company to fix the transmission issues for $305 a vehicle, which would have cost GM about $592 million, according to the lawsuit.
GM instead only replaced the defective transmission in 6,518 unsold Cadillacs and trucks in certain states where it expected customers to complain within warranty, the GM class action claims.
Six drivers filed a 2022 class action lawsuit alleging that several vehicles manufactured by GM are equipped with defective eight-speed transmissions and that GM concealed the defects from buyers for years.

444 thoughts onGM transmission class action to proceed
I owned a 2018 Silverado High Country w/4 wheel drive. The truck was in the shop on numerous occasions for a repair of a shudder situation. GM suggested fluid flush, change in programming, etc. but the repairs never worked. I finally got rid of the truck after 30,000 very frustrating miles of ownership. Iโm sure the service writer at my dealership would attest to my frustrations.
I have a Cadillac and it has one of those transmission in it and Iโm having trouble with it.
I have a GMC Acadia and I have this transmission problem. How do I get added to this
I had this problem in my 2012 Sonic. I always felt like the transmission would fail and leave me stranded. I hated the jerky feeling. I traded it in for a Nissan. No more GM transmissions for me!
Please add me
I work at a Cadillac dealership and customers have complained about this issue for many years. Back in 2018 we spoke to a GM engineer about the issue and what they were doing to correct it. The engineer states they built a ten-speed transmission for the 2019 and up Escalades but were doing nothing to correct the 8 speed.
I have a gmc acadia and I have this issue who can I speak to about it?
Please add me. I had to replace my transmission in my GMC.
I own a 2016 Cadillac ATS-V and not sure what transmission is in it but itโs currently at the dealer for a transmission repair to the tube of over $6k. I would like to be added
add me as well. thankyou
