What stands out
Powertrain accounts for 53% of every owner complaint on file for this vehicle — the dominant problem area across 7 categories tracked.
Owners have filed 73 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
"Flash: Drivetrain Control Module (DTCM) Updates Customers may experience the following: ● A moan noise or shudder feeling from the rear axle during low speed cornering, most notable in a parking lot or low speed maneuvering.

The failure pattern owners describe
Owners describe a pattern of catastrophic powertrain failures that render vehicles undrivable with little to no warning. The Power Transfer Unit (PTU) is the most common culprit, failing between 40,000 and 99,000 miles and causing sudden loss of drive power, grinding noises, jerking, and inability to move in Drive or Reverse. One failure occurred at just 5,696 miles. Metal chunks and slime inside the PTU case indicate internal component collapse. Even after replacement, many owners receive defective PTUs or experience the same failure again within weeks.
Transmission slipping and delayed engagement appear early, sometimes within the first 2,700 miles, often accompanied by hesitation and hard jerking into first gear. One owner had the transmission completely replaced by the dealership but the issue recurred, suggesting a deeper systems problem rather than a transmission-only defect.
Electrical and engine control issues also emerge early—stalling at traffic lights, inability to shut off the engine, loss of brake lights and wipers, and dashboard lights cycling on and off. Dealerships perform PCM updates and resets but cannot identify or fix the root cause.
Loss of 4WD functionality and automatic parking brake malfunction occur together, leaving vehicles unable to shift or move. Owners report being stranded on interstates in fog and snow, in traffic, and at intersections. PTU replacement parts are routinely on backorder for 1–4+ months. Dealerships are turning away customers or demanding cash because warranty has expired, and no recall has been issued for the 2021 model despite prior-year recalls for identical PTU failures.

Failure modes owners describe
Power Transfer Unit (PTU) failure
The PTU fails catastrophically, causing loss of drive power, grinding noises, jerking, and inability to accelerate. Owners report metal chunks or slime inside the unit, overheating, and recurrence even after replacement. The part is frequently on backorder for months, leaving vehicles stranded.
When: Typically 40,000–99,000 miles; one failure reported at 5,696 miles
Symptoms owners cite: Sudden loss of power to wheels while driving; Grinding, clunking, or jerking sounds from powertrain; Vehicle will not move in Drive or Reverse despite engine running; Service 4WD warning light illuminates; 4WD unavailable or reduced functionality message; Engine revs with no power transfer; Whining noise when attempting to accelerate; Vehicle rolls backward when stopped or shifts harshly from Park to Drive
Codes mentioned: P0934 (Hydraulic Pressure Sensor Circuit Low)
Repairs/costs cited: PTU replacement costs $2,500–$4,000+ plus labor. Replacement units are frequently defective or on backorder for 1–4+ months. One owner reported dealership disabled safety features (front collision warning, AWD power transfer) while waiting for parts.
Recalls/TSBs owners mention: Recall 21V-310 (Transmission Oil Cooler Hose) exists but was only 'inspected' not repaired on at least one vehicle. Prior model years (2017–2020) have had three recalls and five parts revisions for PTU. No recall issued for 2021 model despite pattern. Manufacturer denies warranty coverage on vehicles outside 60,000-mile window.
Transmission slipping and delayed engagement
Transmission delays shifting into gear, slips out of Drive into Neutral, or hesitates during acceleration. In some cases, replacement transmissions are installed but the issue recurs or occurs in newly replaced units, suggesting a broader systems problem.
When: Early in ownership (2,700–36,000 miles reported); can recur after replacement
Symptoms owners cite: Delayed shift into Drive or Reverse from Park; Vehicle slips out of Drive into Neutral spontaneously; Hesitation or lag during acceleration; Hard jerking or slamming into first gear; No power response when stepping on accelerator; engine just revs; Transmission grinding noise; Low transmission fluid or metal particles in transmission fluid
Codes mentioned: Check Engine Light (specific codes not always documented)
Repairs/costs cited: Full transmission replacement performed on multiple vehicles. Costs unknown in narratives but owner noted the 948TE 9-speed was replaced at 75,000 miles and dealership refused goodwill assistance despite vehicle being 'just outside' drivetrain warranty threshold.
Recalls/TSBs owners mention: Replacement transmissions sometimes fail within weeks or months, or defective replacements are sent. No manufacturer assistance offered beyond warranty period. One owner had entire transmission replaced at 2,700 miles under warranty after dealership held vehicle for over 2 months unable to diagnose electrical root cause.
Rear driveshaft detachment and differential failure
Rear driveshaft detaches from the vehicle, striking the ground and causing clunking. Differential and transmission control module (DTCM) also fail in some cases, leaving vehicle sluggish after repairs.
When: 27,364 miles reported for driveshaft detachment
Symptoms owners cite: Loud clunking sound from rear of vehicle; Vehicle will not accelerate properly; Grinding or clunking when shifting
Repairs/costs cited: Rear driveshaft replaced. Rear differential and DTCM replaced in another case. Local dealer could not determine cause of detachment. Vehicle remained sluggish after repairs.
Recalls/TSBs owners mention: No assistance provided by manufacturer when notified.
Shift actuator fork wear and PTU internal damage
Shift actuator forks wear prematurely, causing grinding transmission noise and loss of drive power. PTU case contains metal debris, indicating internal component failure.
When: Early ownership to 50,000 miles
Symptoms owners cite: Grinding noise when shifting from Drive to Park; Loss of forward motion despite engine running; Dashboard lights flashing on and off; Metal chunks and slime inside PTU case
Repairs/costs cited: Shift actuator replacement performed. One owner reported metal in PTU case requiring replacement; estimated repair time May 2025 or later due to parts unavailability.
Recalls/TSBs owners mention: None documented. Owner reported contacting Stellantis twice with no case manager callback.
PCM/engine control module electrical failure and intermittent stalling
Engine control module or powertrain control module faults cause repeated stalling, loss of electrical functions (radio, wipers, lights, fuel gauge), and inability to shut off vehicle. Issues recur even after PCM replacement or software updates.
When: Early ownership; some issues at 2,700 miles
Symptoms owners cite: Vehicle stalls at traffic lights or while driving with no warning; Low fuel light illuminates despite full tank; Unable to turn off engine; must tow; Brake lights, signal lights, wipers, radio do not function; Dashboard warning lights appear and disappear; Windshield wipers activate erratically; Vehicle loses all electrical power while driving
Codes mentioned: Check Engine Light
Repairs/costs cited: PCM updated (old part 68493558AD to 68493558AG per one report). Engine controller and crankshaft position sensor replaced. Software updates attempted but did not resolve issues. One vehicle held in shop for 50+ days unable to be diagnosed.
Recalls/TSBs owners mention: Dealers reset clusters of alerts but could not guarantee recurrence would not happen; did not identify root electrical cause. One owner expressed terror at being sent home in vehicle with unresolved issues.
Unwanted torque and involuntary acceleration
Vehicle launches forward on its own or revs with unexpected power while stopped, despite brake pedal being fully applied. Occurs multiple times in succession.
When: Occurred shortly after purchase in one case
Symptoms owners cite: Vehicle accelerates forward on its own from complete stop; Happens multiple times in succession despite braking; Engine revs unexpectedly
Repairs/costs cited: Owner recorded video and provided to dealership; no repair narrative provided.
4WD actuator failure and loss of 4WD functionality
4WD actuator fails, causing loss of 4WD capability and Service 4WD warning. Vehicle loses traction and stability control, particularly hazardous in winter or on hills.
When: 40,000–74,000 miles reported
Symptoms owners cite: Service 4WD light illuminates and remains on or cycles on/off; Message: '4WD System Unavailable Service Required' or '4WD Neutral Warning'; Loss of 4WD traction on highway in snow; Loss of stability control; Vehicle loses power during deceleration
Repairs/costs cited: 4WD actuator replaced; transmission replacement also required in at least one case. Parts on backorder.
Recalls/TSBs owners mention: No recall issued. Dealerships attribute to faulty sensor or PTU but parts are unavailable.
Automatic parking brake engagement malfunction
Parking brake engages automatically without driver input when shifting between Park and Drive, or remains engaged, preventing vehicle movement. Vehicle can roll backward or forward while parked.
When: Associated with Service 4WD failures; unclear if separate root cause
Symptoms owners cite: Parking brake engages automatically when shifting into Drive or Reverse; Vehicle will not move despite being in Drive; Vehicle rolls backward out of Park despite brake engaged; Must disengage brake manually to proceed
Repairs/costs cited: No repairs documented; owners disabled brake to move vehicle.

PTU is going out causing jeep to not have 4wd. 67k miles. Causing the jeep to not be able to get traction on a busy highway causing a traffic jam in snow. Putting people’s safety at jeopardy.
While I was trying to get onto the interstate my vehicle would not accelerate. I tried to merge in with traffic but I was only going 35 and I almost hit someone. They stayed the same speed hoping I would speed up in front of them but I couldn’t. This put everyone around me at risk. I took my vh to the dealership. They called me today and told me they sold the rental I was in and that I needed to…
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…
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
Engine oil color is made of plastic and can crack and can cause you to lose your engine to no oil pressure and coolant and can cause an accident if you do not know because it would lock up the engine
The rear differential PTU can cause the car to lose all control if it fails and this was a proven issue on previous Cherokee models and this model inherits the same issue
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…
Driving on the road when the power transfer unit failed. Car would was not in gear, was able to get to side of road but could have been very dangerous. Towed to dealer and was told that part is on back order and would be 1-2 months to get it and there are55 on back order. Factory has hold on them. This is warranty under the power train and should be in stock . This type of failure could cause a…
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.
