There are 50 owner-reported powertrain & transmission complaints for the 2021 Jeep Cherokeein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2021 Jeep Cherokee. While driving at an undisclosed speed, the vehicle abruptly lost automotive power, and the vehicle coasted to the side of the roadway. The contact stated the power transfer unit had failed, causing the transmission to become inoperable. The vehicle was towed to a dealer and was diagnosed with PTU failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 88,000.
The 948TE 9-speed automatic transmission failed at approximately 75,000 miles on my 2021 Jeep Cherokee V6 80th Anniversary Edition. The Engine light eliminated while traveling down the highway. No noise or indication of engine or transmission trouble, Decided to head directly to the dealership. When I approached my first light off the exit (still no sign of trouble) the vehicle rolled backwards. Applying breaks to avoid collisions with vehicles behind, I tried accelerating with little to no power from the transmission. The vehicle is currently at an authorized Jeep dealership and available for inspection. This condition created a safety risk because the vehicle hesitated entering traffic and rolled backward while stopped, increasing the risk of collisions. An engine warning light illuminated while driving prior to complete drivability failure. Symptoms included delayed engagement and slipping from a stop, which worsened rapidly after the warning light appeared. The failure has been diagnosed and confirmed by an authorized Jeep dealership, which determined the transmission requires full replacement. The vehicle has been inspected by the dealership service department. No crash occurred, so no police or insurance inspection was involved. Jeep dealership would not offer any goodwill assistance despite being just outside the threshold for drivetrain warranty.
the light came on that says cannot move vehicle, it just stopped. The Power Transfer Unit went out--I cannot get a part since it is backordered over 1200 people right now are having issues with the part of the vehicle
PTU Failure. Known issue. 2017-2019 recalled but the part is still and issue and can lock up transmission. Recall needs to be extended to cover later years
I took my vehicle to dealer shortly after purchase due to jerking forward during stops. A software update was performed and did not have any issues until recently. The past few weeks it began to hesitate upon acceleration and jerked forward harshly into first gear. Today there is a very noticeable prolonged hesitation during acceleration and an odd revving noice coming from TPU. This should be a major recall given the frequency and severity of the issue which could lead to a crash.
I was driving on the interstate at approximately 70 mph when I attempted to accelerate to pass another vehicle. There was no response. At first, I thought I might have hit a patch of ice, but I quickly confirmed that wasn’t the case. I tried to accelerate again, and once more nothing happened—other than the engine revving. No warning lights appeared to indicate a problem. I coasted to the next exit and was able to safely park the Jeep. I then had the vehicle towed to a local Chrysler dealership. As it turns out, the Jeep had suffered a catastrophic failure of the PTU (Power Transfer Unit), which I understand has been a known issue for Jeep for several years. The dealership received a replacement PTU, but they quickly determined that the replacement unit was also defective.
The contact owns a 2021 Jeep Cherokee. The contact stated that while driving 50 MPH on the highway, the vehicle lost 4WD functionality. The message “Service 4WD” was displayed. The vehicle was taken to the dealer, where it was diagnosed and determined that the 4WD actuator had failed and the transmission needed to be replaced. The vehicle was not repaired due the part to repair the vehicle not being available. The manufacturer was not notified of the failure. The approximate failure mileage was 44,600.
While driving on the highway a message popped up that the 4 wheel drive system was unavailable. Then the orange error message displayed the svc 4wd. Then it went off. I called the dealership and was told to get it checked sometime, but since it went off there was no rush. I told him to check it when I brought it in for an oil change. Apparently they did not check it for error codes. No error messages or lights when I went to work. Came out to go home and the battery was dead. Called the dealership for a jump. They came and jump started me. When I put the car into reverse, it wouldn't go. I called the dealership again and they came back and said I'd need to get my Jeep towed to them. My Jeep was towed on Wednesday, October 29. It took the dealership a week to look at my car and find out that the PTU had metal chunks and slime in it.
The vehicle was sold by DriveTime (Highland, Indiana) on August 29, 2025, with a known safety recall (Y18 – Transmission Oil Cooler Hose, NHTSA 21V-310) that had not been properly repaired. Jeep dealership documentation dated October 17, 2025, shows the recall was only “inspected” but no repair was completed. Within 30 days of purchase, the check engine light began turning on and off intermittently, and an AutoZone diagnostic (Code P0934 – Hydraulic Pressure Sensor Circuit Low) confirmed a powertrain failure related to the transmission system. The defect affects hydraulic pressure and gear shifting, creating an unsafe driving condition that risks transmission failure while in motion. The issue has been confirmed by both AutoZone and the Jeep dealership but not repaired. Dealer and warranty administrator SilverRock have refused to provide repairs or a loaner vehicle. Both entities were notified that the vehicle is used by a disabled driver and child, and this refusal poses serious safety and accessibility risks. Despite multiple warnings, both companies continue to deny responsibility, violating federal recall obligations under 49 U.S.C. §§ 30118–30120 and creating an ongoing risk of engine/transmission failure while driving. Related complaints are active with the Indiana Attorney General (Case #11811118) and the Federal Trade Commission.
PTU failure
The car is reporting service 4WD, they are saying the PTU is bad. Took it into the dealership today.
The service 4wd light is on. The dealership said it is a PTU problem. They want $2500 for a new PTU and of course add more money for labor. This seems to be a manufacturer problem not a car owner problem. It should be a recall item as it has been for 2017-2019 Jeep Cherokees. The dealer should fix this at no cost to the auto owners.
Our Jeep has had multiple accounts of shifting hard, hesitation while shifting, making a hard sound when putting in reverse and now it is having trouble starting up. When we charged the recently purchased (brand new) battery, the vehicle will start up but when placing in reverse it shifts so hard that it sounds like the bottom is dropping out. Now a lot of lights are shining on my panel; the check engine light, the forward collision light, the parking break light, the regular brake notification, the traction control light.....all shining up like Christmas lights. This is an ongoing issue and I feel a recall needs to be done. My car is over the warranty time frame and for a 2021 model that was purchased brand new I should NOT have to be replacing a transmission already and paying out of pocket expenses.
Incident occur on 25 August, 2025: While driving I experienced a violent jerk and sudden loss of power. The vehicle continued to drive with attenuated power, jerking motion during gear shifts, and loud clucking sounds coming from powertrain. There were no injuries or accidents as result of malfunction. The vehicle was later taken to dealership for diagnosis. The dealership determined root cause as a Power Transfer Unit (PTU) failure. PTUs for this vehicle are on backorder or not available from manufacturer. This vehicle is 2021 Jeep Cherokee Trailhawk 4x4 edition with a 3.2L V6 engine and automatic transmission.
My vehicle was driving fine and I pulled up to a stop light. When I stepped on gas to drive after the light switched, the car would not move and made a loud noise. The brake automatically kicked in and car would not move. This could have been very dangerous as someone could have slammed into the back of my car which could have caused serious damage to me or my children. There was absolutely no warning of anything wrong with my car. I had to have my vehicle towed to a garage. The PTU in my jeep went with absolutely no warning. This part is on back order apparently because there are so many issues with this part on jeeps. Prior year jeeps have this item as a recall which leads me to believe that this is a Jeep problem that should have been fixed already. So now I am without my vehicle for a month.
When taking off out of my driveway the car hesitated to send power from the engine to the wheels resulting in a delayed start. Unknown which component caused the issue but based on my previous 2014 trailhawks PTU 2 x failure it appears to be the suspect. This placed my me and my family at a risk of a side collision as vehicles drive down our road at high speeds. If we cannot pull out in time, a collision is likely to occur causing serious injury or death. Vehicle I available for inspection upon request but has not been inspected by a dealer, independent shop, of police for this problem and there were no indicator lights that came on.
I have had a service 4wd light on for months. The Power Transfer Case part has been on backorder from jeep for over 4 months and I have been left with out a vehicle this entire time with no updates or information about when the parts will be available.
On May 13th 2025 the 4WD service light came on. We took it to the Dodge Jeep Ram dealership that owns the used car dealership we bought it from. After the mechanic checked everything, they said it was drivable but they needed to order a car part (PTU). Once that car part arrived at the dealership they would have us bring the car back in and they would fix it. On July 8th of 2025, stil no news on when the part would be delivered to the dealership, the car started making weird noises and was not drivable on the road. AAA towed it back to the dealership where they confirmed the Power Transfer Unit stopped altogether (PTU). From there they said they will keep the car until the part comes in, the car part was estimated August 8th. It is now September 11th and they still have not received the part to fix the car. I have contacted Jeep Customer Service, a Law Firm, etc as there is no recall open on this vehicle and it seems to be an issue as our dealership said there were 10 other Jeeps waiting for this part.
The check 4wd light on, the PTU needs replaced
The power transfer unit failed and lost power lots of grinding noises and could even roll when in park. What worries me more as I read about this is how many seems to be failing
