2020 Jeep Cherokee Powertrain & Transmission Problems

I was driving on the highway on my way to work around 7:45 am. As I was driving my car lost all power and I heard a grinding sound. As the grinding sound was happening, I had no control over my car. I managed to move to the side lane and put my hazards on. I then had to wait for a tow truck. Ultimately, the brakes, the transfer case, and the rear differental needs replaced.

The systems that failed included the shifter, which causes the car to lock so that it cannot shift out of park . This is most likely due to a shifter assembly and/or sensor malfunction. Several months prior to this event occurring (i.e., the car would not start, despite a new battery and consistent scheduled maintenance), this operator of the vehicle complained to the dealership that the car started to feel tremulous, along with the gas gauge reading 30-40 miles below the expected fill on a full tank. The dealership "checked the sensors" and determined nothing was wrong. The driver has been noticing shaking and continued problems with this vehicle shifting in and out of lower gears (1st through 3rd in an automatic V6 engine). The culmination is now this car will not start, and states both 'service shifter' and 'brake sensor service' lights illuminate upon attempting to start the engine. From reading, it is likely to have a transmission range sensor failure, a faulty shifter module, or wiring corrosion. Also, Stellantis (software manufacturer for these sensors) has admitted fault of these sensors in the past, and had extended warranties for some, but not all vehicles. Unable to operate a nonfunctioning vehicle now stuck with towing to a dealership I've not had good results with since the purchase of this vehicle.

I’ve got the dreaded service 4wd light coming on which means my 4wd system is not working. It’s also known as the C14A7-97 DTC. I bought a 4wd vehicle to have 4wd not front wheel drive. I drive approx 130 miles a day in rain, snow, ice, mud, etc so I need a vehicle that I know will get me to my destinations. I ask dealers about my problem and they are like oh another ptu issue. There’s many jeeps with the same problem. That makes a person feel better. Parts are back ordered but also my 2020 doesn’t fall into recall even though it’s the same issue as the prior jeep Cherokee years. Apparently this is a very well common problem but they refuse to fix them. Shouldn’t have to be worrying about these kinds of problems when the vehicle don’t even have 50k mileage yet. I’ve read on many different forums to report about this issue to you. Thanks

The power transfer unit stopped working and we got a message on the dashboard about the four-wheel-drive not working. We had to replace the PTU

The contact owns a 2020 Jeep Cherokee. The contact stated that while changing lines and attempting to depress the accelerator pedal, the vehicle failed to respond with a grinding sound coming from the front of the vehicle. The contact pulled over into a parking lot and attempted to shift to park, and the vehicle started to reverse unintendedly. The contact stated that after returning to the residence, the vehicle was parked and the parking brake was activated to keep the vehicle from moving unintendedly. The “Service 4WD” warning light was illuminated. An independent mechanic was contacted. The vehicle was taken to the independent mechanic, where it was diagnosed and determined that the PTU needed to be replaced. The vehicle was not repaired. The failure had occurred twice. The contact associated the failure with NHTSA Campaign Number:25V011000 (POWER TRAIN); however, the VIN was not included in the recall. The manufacturer was notified of the failure and referred the contact to another dealer to seek assistance with repairing the vehicle. The failure mileage was 68,000.

No accident or incident cause issues with the power train. Seems like a recurring problem that this specific model of Jeep has been facing.

Warning light came on that said "Service 4WD System" at approximately 86,969 miles on a 2020 Jeep Cherokee Trailhawk. Took to dealer and was advised that PTU (power transfer unit) must be replaced at a cost of $3,945.19. Was also advised that DTCM "transfer case control module must be replaced at a cost of $776.95. Total cost to resolve "Service 4WD System" problem as quoted is $4,722.14. It has been noted that older versions of this same vehicle model have been recalled by the manufacturer for this same problem. I would like to know why this particular model year has not been included that recall as it appears that the earlier noted manufacturing defect was not corrected for the 2020 model year.

Issue #1: Fuel pump failure, had to completely replace the fuel pump at approx. 60,000 miles. Approx. $1,300 repair. Issue #2: Rear differential failure due to faulty/poor construction of materials, per the repair shop. Failed at approx. 63,000 miles. There was no external damage to the differential, it was caused by poor construction/defects of the materials used to build the car. Approx. $4,500 repair. Both issues are KNOWN issues with Jeeps of this model year, to the extent that I have not been able to find replacement parts due to them being in such high demand.

Failed Power Train Unit, and this is available for inspection. I was driving on the highway with my grandson and husband going 70 mph when the unit failed it basically felt like the car was thrown into neutral. Thankfully no one was hurt. Dealership has confirmed the issue. No issues driving the vehicle before the issue after the issue the light did come on and the vehicle is undriveable.

My PTU failed while driving 70mph on a 4 lane interstate during a heavy rush hour, I'm 7 months pregnant and this was mortifying for me. I lost all power moving forward and could not accelerate. My RPMS would near red-line. When I pulled on to the shoulder, while trying to not get hit or cause an accident from 3 lanes over, I put my car in park and shut it off, it sounded like a dying weedwhacker. It started rolling backwards without me noticing and I almost rolled back into the outside lane. I put on the e-brake, had it towed to Firestone where they said it was likely the PTU that failed as I have every gear, except moving forward. When they had my vehicle on the lift they moved the tires in reverse motion and there was no noise, when they moved the tires in forward motion there was a loud knocking coming out of the PTU and the tires wouldn't budge. If in park on a decline, park works. If in park on an incline or flat, it rolls backwards. It can drive in reverse, but no forward movement at all. I got it towed to another shop where they took out&opened the PTU and checked the gears on the shaft inside, one of the gears was COMPLETELY MISSING. Just completely disintegrated. There was NO warning that anything was failing on my car. No check engine lights, no noises. Just loss of acceleration. PTUs are on back order 3-5 months right now because they're a known issue on the 2017-2019 models of Jeeps. My Jeep is a 2020 Trailhawk with the v6 3.2l.

4wd service light came on. The code was c14a7-97. A well known PTU problem. There was a previous recall for the same problem. It can be a dangerous situation if it completely fails while driving. Also a very expensive repair bill. My 2020 Jeep Cherokee only has 72k miles and a has a major known failure already.

Transfer case failure, I had started to notice as if the transmission were shifted to neutral, high engine rpm and no output to the wheels. This happened a few times but not consistently. After the 3rd time this occurred, I decided to bring the vehicle in to a well-known local shop transmission shop. It was diagnosed as the transfer case a known issue with previous years. Still such a popular failure that local dealerships were told by Mopar they could only order one replacement per month. I was without my vehicle for nearly 3 months while it was inoperable. The vehicle is now repaired with a Mopar remanufactured transfer case. $3000 and 10 weeks later.

While driving in northwestern Pennsylvania during a snowstorm, the driver engaged the vehicle’s factory “Snow Mode.” Immediately thereafter, the vehicle experienced a sudden loss of power and loss of steering control. The driver was forced to pull off the I79 interstate in severe winter conditions and exit the vehicle to avoid being struck by a snowplow. This created a dangerous roadside exposure and a significant risk of collision or injury. The vehicle was towed to a Jeep dealership and diagnosed with a failed rear differential requiring replacement. The dealership stated the part has been on national backorder since 2024, with no estimated availability. The failure occurred without warning and rendered the vehicle completely inoperable. The dealership further advised that this rear differential failure is a known issue, and recommended against installing a used replacement due to reliability and safety concerns. Safety Concern: This failure resulted in: •Sudden loss of vehicle control in hazardous weather •Loss of motive power •Forced roadside exposure in active traffic conditions The inability to obtain replacement parts compounds the safety risk by leaving the vehicle unusable and preventing timely repair. Request: I am submitting this complaint so NHTSA can evaluate whether this represents a systemic safety defect related to the rear differential in this vehicle platform, including failure mode, warning adequacy, and parts availability affecting safe remediation.

The contact owns a 2020 Jeep Cherokee. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. The message "Service 4WD System" was displayed on the instrument panel. The vehicle was taken to the dealer; however, no cause for the failure was found. The vehicle was not repaired. The vehicle was taken to an independent mechanic and was diagnosed with PTU failure. The vehicle was not repaired, and the failure persisted. The contact related the failure to NHTSA Campaign Number: 20V343000 (POWER TRAIN); however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.

The contact owns a 2020 Jeep Cherokee. The contact stated that while accelerating from a stop, the vehicle stalled. The transmission message was displayed. The vehicle was taken to an independent mechanic, and there were metal particles in the transmission fluid. The vehicle was not repaired. The mechanic called an unknown local dealer and confirmed that parts were on backorder. The manufacturer was not contacted. The failure mileage was approximately 50,000.

When I attempted to turn left onto the highway from a complete stop on an incline, I pressed the accelerator and the car made a loud grinding noise. The vehicle would not move forward or reverse. The parking brake engaged on its own and would not disengage. After exiting the vehicle, I found a loose bearing behind the car. The vehicle had to be towed to a mechanic. I was informed by the mechanic that the failure was caused by the PTU (Power Transfer Unit), and the repair cost me $2,600. I was later told that the initial failure had also stripped another component, which required an additional $100 repair. I was not given the specific name or details of that additional part.

2020 Jeep Cherokee Power Transfer Unit (PTU) Per a discussion the dealer service manager, I realized the vehicle is undrivable because the PTU could fail at anytime. The danger is losing propulsion to the wheels on an interstate or other high speed or high capacity road. The problem was discovered by the dealer when I took my Cherokee in on 11/24/25 to have them fix the "SVC 4WD" warning light. Once they explained the issue I decided to leave the vehicle at the dealer to replace the PTU. There is no timeframe for them to receive a new PTU. Jeep had recalled 2017-2019 Cherokees due to issues with the PTU. The 2020 Cherokees should also be recalled so owners don't have to pay for an issue Jeep is aware of with the power train.

The 4WD service light indicated an issue. After a week of the light staying on, the vehicle was brought to a local dealer for diagnosis. After diagnosis from a dealer, the PTU failed which can result in complete propulsion of vehicle.

Vehicle has been having a grinding noice since I bought it, had it checked and nothing came up. Now service 4x4 light comes on intermittently. Took back to the dealer and diagnostic says that the ptu has low voltage. Needs to be replaced. I have to pay for the part first ($2000), but it's been on back order for over 6 months.

The "4WD Needs Service" light appeared on the dashboard of our 2020 Jeep Cherokee Trailhawk. We took vehicle to the Enumclaw Chrysler Jeep Dodge Ram dealer located in Enumclaw, WA. Their service technician determined that the PTU (Power Transfer Unit) was failing and found active code c14a7-97 "ptu motor-component or system operation obstructed or blocked". Had the PTU completely failed we could have been left without any power to the drive wheels. This would have been very dangerous if the vehicle had lost power while driving on a freeway or major highway and the vehicle could not have been driven to a safe location. The dealer replaced the PTU and confirmed that the problem had been repaired. We don't know if the defective part is still available for inspection.
