Jeep Cherokee – unexpected 4wd / ptu issue out of nowhere, my Jeep Cherokee displayed a message on the dashboard saying “service 4 wheel drive. ” I was driving normally at the time — no impact, no off-road driving, and nothing unusual occurred beforehand. After taking the vehicle to my mechanic, I was informed that the issue might be related to the ptu (power transfer unit). It seems the system failed without any warning signs. Now, every time I start the car, the same “service 4 wheel drive” message reappears. There are no strange noises or performance issues at the moment, but the warning remains, which is concerning and will need further inspection.

When driving the Jeep Cherokee (51,000 miles), I experienced numerous incidents where the car experienced sudden power loss climbing a grade followed almost immediately by numerous warning lights and a message that "4wd system unavailable" as well as a message that the forward warning system had failed. Under these conditions, the car struggled to make even 50 mph and would only do so in a much lower gear at 4000+ rpm. Prior to each incident, the car had been driving smoothly at 70 mph at approx 2200 rpm. Both the Jeep dealer and the local repair obtained the same error code (dtc c14a7-97 ptu motor component) indicating internal failure of the ptu (transfer case). When the repair shop removed the transfer case they found metal shavings in the ptu lubricant. With no ptus available from the Jeep dealership for months it was necessary to purchase a salvaged ptu at near-new pricing. I note that there is a similar recall but it does not cover my vehicle. I also note there are numerous NHTSA complaints for identical problems being filed nearly daily for 2017-2021 Jeeps. This defect is a serious safety issue that can result in complete driveline failure or an inability to maintain speed with traffic. It also results in approx $5000-7000 in repair costs for each ptu replacement.

This vehicle had multiple reprograms for transmission control module and still had same issue I have only had the vehicle 1 year and driven it 7k and I take. It to jim browne Jeep dealership they said they transmission control module needs replacement the Jeep when I brake jumps forward and speeds up its unpredictable and unsafe it also does not shift into gear it slips and I did a search and see.

Last year in 2024 our vehicle started having significant issues with the transmission. We took it to a dealership and through our warranty that we purchased, we were told that the transmission control module had lost its programming but no one understood why. It wasn't covered under our warranty and we paid full price out of pocket for that. Less than a year later we are back with the same issues again where it's not holding on to its programming. It locks itself into neutral when we are driving, it will have surges of power with the battery, and no longer has any emergency braking system. We cannot put the emergency brake on in fact. We lost all of our 4x4 variations such as snow sport and four wheel drive low. Full drive is no longer able to be engaged at all with the transmission. It will not shift in or out of 5th gear which means every time we push on the gas that means it's going to be starting out in 5th gear which is obviously a strain on the transmission. Due to that it has no towing power whatsoever right now. It has shut off completely in the middle of us driving bfore. These issues are causing it to slowly lose it's communication with all of the other modules in the vehicle and the engine itself is no longer communicating with the transmission which makes driving the vehicle almost impossible.

The power transfer unit (ptu) suddenly became disconnected while we were in the passing lane on a highway. We lost power temporarily and dashboard lights came on saying service was needed. Moved slowly into a safe location and called for tow truck. There was some “knocking” as we moved. While diagnosing the vehicle, the dealer experienced the same indications and stated that it sounds like a separation in the ptu. There were no prior indications that something was wrong until it happened. I researched on line and found recalls for this issue in prior years (2017-2019) on the same vehicle as mine (Jeep Cherokee 2020).

I was driving my vehicle and it lost power going down the highway about 65 mph maybe 70. The power shut off on my vehicle and then it came back on but it was very dim and it say that way for till I got out of it and it was very scary my my cruise control keeps shutting off okay I'm having major problems with my transmission it slips a lot I need to know what to do about that.

My service awd light came on. I had the system checked in February of 2025. I was informed it was a bad ptu system. My car makes a clunking then whining noise when driving. It cannot go over 55 mph before losing power. My VIN doesn’t come up in the recall list but it has the same diagnostic issues the issue was diagnosed at heritage Jeep in harrisburg on 2/15/2025 receipt order # 218197. Customer number 42k8761762.

Hi, there are numbers of recalls and 3 of the recalls came back. I got engine light with the codes u0402 implausible data received from tcm u0164 lost communication with hvac control module tcm bcm and pcm needs to be reprogrammed or replaced. Also car is accelerating while cruise control is set. Fca satisfaction notice - r01 fca recall - s55 NHTSA recall - 16v - 529 fca recall - u63 NHTSA recall - 18v - 332 these 3 recalls need to be redone. Thanks.

A few times when I have used cruise control my car suddenly accelerates and takes me slamming on my break for a few seconds to disengage to slow down, almost causing me to crash into someone. I have not taken my car to a shop to have it looked at. There were no warning lights or messages when it happened.

This is the second time that the ptu has failed. Svc 4wd and acc not available again. Radio is malfunctioning.

Cruise control would not disengage. Instead it accelerated me to 85 mph is rush hour traffic. The car continued to accelerate will out responding to any commands to turn off cruise control. Second time this has happened. It was supposed to be fixed by doing an update to the car. This did not work. The second time I attempted to use cruise control after having had the long block engine replaced due to the oil consumption law suit, the car once again had the same problem with now slowing down. I tried putting the car into neutral and pressing the break. The car was accelerating so fast. The brakes had no effect without causing me to lose control. I was forced to put the car into a ditch at 75 mph. Rather than to rear end the dead stopped 3 lanes of traffic ahead of me and being pinned in by the traffic behind me. Car flipped I now have brain damage and failing kidneys due to blood transfusions.

Last week we noticed steering wheel controls not working, steering wheel heater . . Cruise control ,, hands free,controls today took in to Jeep dealer in superior WI was told it is the clock spring , squib,, said that we have to replace entire unit including new airbag . . As we do not know for sure if until the work done ,air bag would deploy as per dealer ,he isn't 100 percent sure. ,and the entire thing has to be replaced at a hefty cost of 1000. 00 as well as safety , being told that other larger trucks and Jeep models have had this as a recall I contacted Jeep and they said nothing they can do ,, but to hang on to receipts in the event of a future recall. . We do not feel that they are treating this as the safety issue that it truly is . This is after we have had rear driver caliper replaced over heating and seizing , at 800. 00. Also been told this is common for Jeep and another safety issue as well . The dealer said both are recall worthy on this vehicle . This has been all within 50 -60,000 miles. . We feel something needs to happen here before someone gets killed. Thank you.

Ptu blew out on the highway at 68mph. Loss of steering. Ptu was replaced at a Jeep dealership and has also failed. I’m now having svc 4wd and acc unavailable. This is unacceptable.

I have a 2015 Jeep Cherokee trailhawk. It has been in the shop many times due to poor manufacturing and recalls. Prior to me purchasing the vehicle in may 2020, it was involved with a recall for a water leak and powerlift gate short due to water damage. It has leaked water into the hatch/ trunk area since I purchased it. I have spoken with 2 dealerships about the issue. The most recent was November 1, 2022 when it was left with rockwall Chrysler. My issue is that the electronic parking brake module was damaged to due heavy rain and the continued leak. On October 30, 2022, we were trying to leave in the Cherokee and the service brake warning light was on as well as service shifter. The vehicle was stuck due to a malfunctioning parking brake. After multiple attempts, the brake disengaged and I continued to work. October 31, when I started the vehicle the following warning/ service lights were on and remains service brake light (2 different lights) acc/fcw not available / service auto start/ stop unavailable/service airbag warning light (went off 11/3/22) 4wd unavailable/service on my drive home from work, the electronic parking brake engaged while I was turning across traffic and I almost was hit by a large delivery truck. Once I managed to get the vehicle to drive, it happened again on the highway service road and I was very close to being rear ended by an 18 wheeler that was driving behind me. The dealership did no repairs due to the $575. 00 charge I cannot pay to diagnose and do a leak test. I explained this was involved with a recall and they basically told me it was fixed in with canada or ohio and I needed to return to that dealer (I live in TX). Which is not possible because the vehicle is sitting in my drive way and will not move due to the brake being stuck on. I picked the unrepaired vehicle up on 11/3/22 and was advised its best to get rid of as soon as possible. The problem is that I owe roughly $13,000 on the Jeep. I cant afford this and a rental.

I brought in my vehicle for the power train update recall and it triggered my shifter light to come on which now they are saying is the shifter bezel and harness and I have to pay out of pocket for. It was not on prior to the recall software update for the power train.

Vehicle started rapidly accelerating and was unable to turn off cruise control. Dash lights flashed on and off. Had to put the car in neutral and slow to a stop.

Car refused to exit cruise control, again instead it accelerated. I pressed again and again cruise control to stop it did not respond. Repeatedly and more frantic I pushed pushed the button as stopped cars grew closer. The car started to accelerate instead and refused to stop even when pressing the brake. I was able to push the brake down enough to get to engage neutral after multiple attempts. I feared fir my life and for others due to not being in control of the vehicle that was not responding to commands. I was told that the vehicle had been serviced for this problem when it happens to me prior and the dealership refused a free update due to a TSB saying it has been corrected already and I would have to pay. The dealer didn’t even not my vehicle as I asked. I was told if I’m not paying I’m not a customer and they don’t note a account for non customers. Jeep dealer greenwood indiana. They also wanted to charge 400 to find out why I had water leaking in the back hatch on the drivers side and said they had no knowledge of a issue with that and would not note a non customer acct for that either. Approximately March of 2022 definitely the year maybe later in the month of the year. It was not winter though.

In December 2021 the "awd not available" warning message came on. During a trip, the cruise control did not work. Took car to dealer on January 4, 2022. Diagnostics revealed the following: oil leak in the engine, repaired under the warranty. Body controller module and body wiring failed, replaced under warranty. Power transfer unit failed, power transfer unit replaced under warranty. Car returned to me repaired on January 14, 2022.

Acceleration and emergency brake when I put on the brakes the car accelerates and trying to get on expressway its a long time before the car can go full potential. The emergency brake comes on unexpected. I dont fell safe when emergency brake comes on at any givin time. If I brake after I let go of brake car accelerates and going on a curve is the same and its very scary. I took to dealer for recall and they updated nodule for gears I went back and they did update on transmission nodule. Got the car back 2 days ago the first day it started again on acceleration after braking. The 3rd day engine light came on. How can they sell a Jeep like this my life is valuable and I dont feel safe. I dont try my car far scared if I get in to an accident and I only had this car for 6months been going back and forth literally everyday to fix the issue and noone is doing anything. Please do something. It has been inspected 4 times and they cant find what the problem is. No warning till 4 months after purchase then engine light was coming on and off.

In the last 3 weeks I start my 2015 Jeep Cherokee as usual, shortly after driving when trying to accelerate from a stop the battery light comes on and the dash says cannot switch gears unless in park. The car then stalls and I have to shift into park and restart ,the scary issue is that I am sometimes stuck and cant move until I can restart the vehicle. There is only 57,000 miles on this vehicle .

Around 2:30 am on December 30, 2020 I was driving home on the freeway. It was raining a little bit but nothing to what I have driven in before. I set my car to cruise at 65 mph when all of a sudden my steering wheel started locking up. I found that my steering wheel would not turn the way I wanted it to and was veering left. I had to use some force to keep it straight and not get into other lanes. I thought I was okay until a light lit up on my dashboard. I believe it was the engine light because as I heard it go off and flash at me, my car started to stall up and then go repeatedly. As if it was hard for it to grasp on to moving forward. Last night was the scariest night of my life and I hand never had that happen to me. Almost pulled over because I thought I was going to crash. I kept it at a stable 60 mph and off cruise control as soon as the steering went haywire and it seemed to have helped a bit. I feel the need to get my car checked but I also believe that all other 2019's should get recalled for this issue.

While driving on a freeway in November 2020 I had engaged the cruise control and set it at the speed limit of 70 mph. A semi truck changed into my lane without blinker warning. I slammed on the brakes but the cruse control would not disengage. I then began pumping the brakes and still no disengagement. As I approached the back end of the semi prior to hitting it, I drove off the freeway down the descending embankment still pumping the brakes without disengaging the cruise control. As I began sliding down the embankment I brakes disengage the cruise control just before a collision with the divider.
