2018 Jeep Grand Cherokee: complete transmission failure

Filed Aug 30, 2026 · Acceleration, Transmission · OH

I am reporting repeated drivetrain and transmission failures involving my 2018 Jeep Grand Cherokee SRT. The problems began with failure of the driveshaft carrier bearing, which was replaced with a brand-new component by an independent mechanic. The transfer case subsequently required replacement and was replaced with a brand-new unit by a reputable dealership. After these repairs, the original transmission mechanically failed at approximately 99,000 miles. I replaced it with a transmission from a 2021 model that had approximately 45,000 miles. That transmission then failed after only approximately 5,000 miles of use in my vehicle. I am now having another transmission installed, meaning my Jeep is receiving its third transmission. By the completion of these repairs, I will have spent more than $20,000 addressing drivetrain and transmission failures. I am concerned that an underlying drivetrain, transmission, electronic/control, or other vehicle-related condition may be contributing to these repeated failures. Replacing major drivetrain components has not resolved the problem, and I am concerned about the safety and reliability of the vehicle. I am also aware of a similar situation involving my niece’s 2021 Dodge Durango R/T with approximately 60,000 miles. Her vehicle is also on its third transmission, with brand-new replacement transmissions being installed under warranty. I am requesting that the federal safety agency review these repeated failures and determine whether similar transmission or drivetrain problems have been reported and whether they may indicate a safety-related defect or broader pattern.

I Purchased my my vehicle from a dealer approximately two and a half months ago. While driving the transmission of the vehicle gave out. The car rpm shot up to seven thousand and only goes 30 mph. My safety was in jeopardy because the vehicle lowed down rapidly and I had to maneuver to the side of the road in order not to be struck from the rear. I had taken it to get inspected by AAMCO and was informed that the transmission failed.

Transmission failed while driving. Had someone been behind me they would have hit me. It was towed to a dealer and through the extended warranty it was deemed a faulty transmission. There was no indication of an issue until it happened. Once the transmission failed the check engine light came on.

I've had my car in the shop 4 times for well over 85 days and it's still having the same transmission problems. I have very hard shifting with acceleration and deceleration, I have had the vehicle get stuck in first gear while making turns onto streets and I've had it surge forward on me. I've had updates, parts within transmission replaced and a new transmission. I now have been told that they couldn't replicate my issue and when I took it off the lot it did the hard shifting and then it got stuck in first gear while making a turn. This has always occurred in city driving, any weather conditions. I've been told that the hard shifting is normal in all 8 speed transmissions. I do not feel safe driving this vehicle. I have had several instances that a wreck has almost occurred due to it not shifting out of 1st gear. I was told that they can't go to chrysler about a buy back since there is no error code. I guess I'm supposed to put my life/family in harms way.
