The vehicle has developed a safety-related defect involving the rear differential. During low-speed turns from a stop, in both forward and reverse, the rear drivetrain exhibits grinding, binding, and wheel hop, causing the vehicle to jerk and resist normal movement. This condition affects the vehicle’s predictable handling while maneuvering in parking lots, intersections, and other confined areas. If the rear differential continues to deteriorate, it could result in catastrophic drivetrain failure and a sudden loss of vehicle propulsion, leaving the vehicle unable to move and potentially stranded in an active traffic lane or other hazardous location. This defect presents an unreasonable risk to the safety of the vehicle occupants and other road users and should be investigated as a potential safety-related defect.

Upon exiting a major interstate highway, I slowed down and attempted to merge onto a divided highway. The vehicle (2021 Jeep Cherokee Trailhawk) did not respond, as their was little or no power. Cars behind me, took actions to avoid me. After coasting to the shoulder of the divided highway, I placed the vehicle in park and then back into drive. I experienced a grinding, oscillating noise and a dashboard warning message stating to service 4WD system. I repeated this procedure and was able to advance the vehicle at a slow/steady pace to a local Chrysler, Dodge, Jeep dealership, not far from the malfunction. Dealership has confirmed a major PTU failure, one of the "worst" they have seen. I was also informed that the stated wait on replacement parts is 45 days.

I have had 2 incidents involving drivetrain failure which almost resulted in accidents. On 26 September 2024, I was in left lane passing other vehicles when suddenly my vehicle (2021 Jeep Cherokee Trail Hawk) started jerking, felt and sounded like something exploded under vehicle. I was among a group of vehicles, including semi trucks with trailers, both behind me as well as along side me. Vehicle suddenly lost forward motion, engine rpm kept increasing and decreasing, vehicle would jerk like something in drivetrain was binding up but still did not have forward power and losing speed. Dash lights started coming on and going off, then check engine light remained on. while still in passing lane, I had no power to drive forward so I immediately signaled to attempt a safe maneuver in traffic to right edge of road as there was no space on left shoulder. Several vehicles had to swerve to avoid hitting us, a very frightening and unsafe experience. Once I was on side of road, vehicle would not move in any direction, transmission made like a grinding sound if put from drive to park. Vehicle was towed to Papik Motors for repair. Dealer determined shift actuator forks were worn and replaced shift actuator. there were no loaner or rental vehicles available from dealership, I had to rent a Uhaul to get us and camper home. Vehicle returned 4 Oct 2024. On 21 January 2025 while attempting to pass a vehicle on 2 lane highway, my transmission seemed to go into neutral as I was passing causing me to almost be hit by oncoming vehicle as I had lost forward motion. After stopping, vehicle seemed to operate fine but on way home, vehicle made loud noises, transmission was grinding and would not drive. I was able to drive in 4x4 low along edge of road to the dealership. they found metal in PTU case. estimated time for repair is May or later due to parts not available. I have loaner vehicle. Contacted Stellantis twice. Case manager has not called back. I do not and will not feel safe driving

PTU in 2021 Jeep Cherokee with 50k miles went out causing a loss in power to the wheels while crossing a highway. Dealership put a new PTU and drive shaft in but said it was defective but they could turn off the Jeeps ability to transfer power from front to back until they got a new part. This caused my safety features such as front collision to be turned off. I assume they pulled a fuse for the transfer between front and rear meaning the new PTU was more than just not communicating with the electronics like the dealership said but was an actual defective unit. The last time it went out it also tore up a drive shaft. The replacement unit in the Jeep has always had a grinding sound and began to have what felt like transmission slip. I also started losing power and when the engine is turned off sometimes it won’t start even though it has power in the battery and the start turns. It is broke down again and going into the shop because the Jeep is still having drive issues along with new electrical ones and I am in danger of it losing power or transmission when crossing a highway. The dealer did tell me that many of the new PTUs are defective. I am surprised a dealership when send a customer back out in a vehicle they knew wouldn’t be safe and had a failed part.
