(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 GM’s 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 transmissionsÂ
The GM transmission issues happen around the time the affected vehicles’ 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.

I have a 2016 GMC Sierra 1500 that my family purchased new. My dad had it until he couldn’t stand the lunging anymore, so my brother bought it from him. He took it to the dealership so many times that by the time the warranty ran out, it wasn’t worth the time or money to fix it. So, I got the truck. I’m not a certified GMC mechanic, but I know my way around a vehicle. I have replaced almost every sensor, spark plugs/wires/coils, read up on service bulletins, reflashed all the modules, and changed fluids. I still have the truck as my everyday vehicle, and it runs great…most of the time. When I start it, it’s like rolling the dice. It might start right up and perform great, or it might sputter, lunge, lose power, and have gear changes that sound like the transmission fell out.
I have a 2019 trailboss LT Silverado. Already been in the shop twice for transmission issues. Had the flush done with no success. Spent over 3k so far on repairs, and then the shop basically gave up and said I may need a full rebuild or new transmission. The truck has 82,000 miles on it….
I own a 2019 Colorado Lt. Between 90k and 98K I’ve had transmission flush twice and new torque converter another flush and new filter installed. 5000$ into it and still shudders. Horrible transmission!
I own a 2018 gmc 1500 denali with the same problem, they flush the transmission and still does it.
I own 2017 GMC Terrain 57,000 miles on it it’s doing the same thing I have been reading about. Took it to the dealership they said they fixed it to the tune of $8000, had to get a loan to pay for it. Had it 2 months same thing started. Had it towed to same dealership again called they said they can’t find anything wrong with it. Wow can’t believe it. It’s unsafe to drive now what do I do?
I have a 2018 gmc sierra sle v8 that it’s transmission went out and had to pull a loan for 5,000 on top of my purchase at gmc dealership under 100,000 miles
I have a 2015 Chevrolet tahoe ltz with a shutter problem. Took it to the shop they said nothing was wrong that I needed to service the transmission$2,000 later still have the problem. . I also own a 2013 GMC sierra where it sounds like the same problem. Got a estimate gonna cost me $3,000 to fix my tahoe. This really sucks.
