2020 Jeep Cherokee: sudden loss of power

Filed Sep 29, 2026 · Transmission · MI

On 9/6, The Cherokee lost power and had a grinding noise when in gear. It was towed to the Jeep dealer, they said it needed a new rear differential.. I told the dealer that my research showed that this catastrophic failure was likely caused by the 40D-recalled PTU and not the rear diff, but they claimed the rear diff was the problem and they could fix it. So, I reluctantly agreed and they proceeded to order the parts - which took a few weeks - to replace the rear differential. On 9/28, I paid $1237 for the repair (Jeep kicked in 80% of the total $5000+ repair cost as “goodwill” - which to me, is an admission that the 40D recall was to blame and the manufacturer knew it) and we drove it home last night. Today, on 9/29, while driving to work, the “service 4WD” warning light came on, based on the recall 40D, this indicates that the car should be immediately taken out of service for safety concerns for potential loss of power or failure to stay in park. So, we are taking it directly back to the dealer tonight. As it has been three months since the recall was announced and there’s no fix or even a timeline on a fix, it may be months before Jeep releases a fix. We are looking for pressure from the federal safety agency for a loaner and/or a buyout on the vehicle, as well as a refund on the $1237 repair cost already paid. We went 3 weeks without the vehicle the first time and cannot be continue to be without the vehicle.

While driving my 2020 Jeep Cherokee Latitude Plus (2.0L turbo engine), the check engine light illuminated and the vehicle began misfiring with a severe loss of power and abnormal engine noise. A compression test confirmed lost compression in one or more cylinders. The dealer inspected the engine and diagnosed internal piston damage, consistent with piston ring land failure. Research shows this is a known failure pattern in 2019-2023 Jeep Cherokee turbo engines, including a pending class action investigation (Sauder Schelkopf) for premature engine failure caused by lost cylinder compression, misfire codes, and dealerships declining coverage. Reports describe melted pistons and collapsed ring lands, often in cylinder #2, possibly related to low-speed pre-ignition or the PCM incorrectly detecting fuel octane and over-advancing ignition timing. The failed engine components are available for inspection upon request. This failure occurred at highway speed with no prior warning beyond the check engine light, creating a safety hazard from sudden power loss. The engine is a 2.0L turbo GME (Hurricane) engine. Please investigate this defect pattern for a potential safety recall.

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 "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.

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 the federal safety agency 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.

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.

While driving, the car began making a rattling noise and felt unstable. Shortly after, the “Service 4WD” warning light came on. I took the vehicle to the dealership, and they diagnosed a Power Transfer Unit (PTU) failure that requires replacement. This is a serious safety concern, as the vehicle could lose the ability to drive, especially in certain road or weather conditions. After researching the issue, I discovered that PTU failures appear to be a widespread problem in Jeep Cherokees, yet there has been no effective recall or permanent fix. Owners are being put at risk due to potential loss of power while driving.

My 2020 Jeep Cherokee was in for a multi-point inspection and oil change on 9/10/2025. On 10/15/2025, the Service 4wd, AWD System Service Required light turned on as I was driving. I called the same dealership immediately and was able to get it in for diagnosis on 10/21/2025 (the soonest appointment available). They called me on 10/27/2025 to inform me that they diagnosed a faulty PTU part #68333254AI. They sent me a quote of $3,129.81 for the part, labor, and fluid. My Jeep has remained at the dealership since it was diagnosed. I was told that there could be a loss of power to the wheels that could result in loss of control and a potential crash. I was also told that it may be an extended period of time before they can get the part. The dealership has stated that this would not be covered under my warranty because the warranty ended on 10/17/2025. The warning light actually came on before this date. I understand that there was safety recall/class action lawsuit for this issue on the 2017-2019 years but not the 2020. I feel that this is a known safety issue and believe that it should be covered by my warranty or the manufacturer. My vehicle's mileage is 43,230 miles.

I dropped my car for a service appointment on October 25, 2025 because the car was running loud at highway speeds and felt as though something was grinding. I was told that the recommendation is to replace the PTU. I was unfamiliar with the term and guessed, "Power Takeoff Unit" and the service technician agreed with me. He then informed me that there was an issue with the part and it would be 45-days before the part would be available. He told me that other shops were contacted and there was no shop in the area that was willing to part with the PTU, and I would need to wait 45-days for the repair. I asked if it was safe to drive the vehicle until the repair and he informed me it was. He appeared to be a new team member, so I clarified again, "I just want to be clear it is safe to drive the car". He responded it was, and then said he would check with his manager. After checking with the manager, he came back and said it was okay to drive the car but it may lead to further damage. Following the call I Googled PTU and learned that there was a recall on Jeep Cherokee's, due to defective PTUs which could cause a loss of power when the vehicle is in motion - leading to a crash, prevent the driver from putting the vehicle in park, or causing the vehicle to come out of park. Given the large number of vehicles involved in the recall, 660K + it is not surprising that the part is on back-order. It is frustrating that this is a voluntary recall, and that the scope of the recall has grown from 2016/2017 to now include 2017/2019 but not yet 2020. Please consider including the cars manufactured in 2020, and changing this from a voluntary recall.
