2021 Jeep Cherokee Engine Problems

Twice in the past year, the vehicle stalled after coming to a stop at a red light. The morning after the most recent incident, the car would not start. I had it towed to the dealership. That was Luther Brookdale Dodge, Jeep and Ram in Brooklyn Center, Minnesota. Two weeks ago, I began to intermittently see the message '4WD Unavailable - Service Required'. I brought it yesterday, and was told that the Power Transfer Unit was in need of replacement. I travel as an special education case manager and teacher quite a distance every day to work. The roads in the wintertime can be quite challenging on which to travel. This vehicle should be included in the list of affected vehicle trims that are listed for the multitude of Jeep vehicles part of the PTU related recall. I need to know that the vehicle is being repaired with a part that is safe, not the same PTU used originally, in manufacture, which has been found to be unsafe.

May 14, 2026

I own a 2021 Jeep Cherokee Trailhawk that is included in the PTU safety recall involving sudden loss of motive power and/or loss of the PARK function. My vehicle began exhibiting the exact symptoms of this recall in April 2026 and has been undrivable since that time. The recall was announced in May 2026, but Stellantis has still not provided a repair remedy. As of today, my vehicle has been out of service for approximately four months due to the recalled condition. I have received the recall notification letter, but it continues to state that no remedy is available. This has left me without the use of my vehicle for an extended period despite an acknowledged safety defect. I am requesting that NHTSA investigate Stellantis’ failure to provide a timely remedy for this safety recall. My vehicle has been undrivable since April 2026 because of the recall condition and remains unusable due to the lack of an available repair. This vehicle CANNOT be safely driven.

Incident

Apr 20, 2023

I purchased this 2021 Jeep Cherokee, and it has developed a life-threatening defect where it performs an uncommanded braking while driving at speed. Without any warning the car slams on the brakes creating an immediate risk of a Rear end collision. Diagnostic scans show multiple critical failures: PO128 (the initial warning of a computer communication issues). Dealership (Echo Park) refuses to fix with the proper OEM part and denies my warranty, (I called it in on day 15 on my Warranty, 01/28/26) I let them know the fans were loud, RPMs fluctuating, tailpipe full of black soot and making a loud sputtering, this is burning up my fuel fast. My appt was on 02/10/26 They said there was nothing wrong with it. A couple weeks go by and then the check engine light turned on (after my Warranty) i took it back on 03/19/26, They visually verified the code, said I had to pay out of pocket to fix it with an aftermarket part not the OEM part. They set up an appt for 03/25/26. UO128 (lost communication with brake control module) and C008E-00(ECU internal performance). These codes are directly linked to the NHTSA safety investigation PE22- 009. When I took the vehicle to Allways [XXX] on March 23, 2026, the Service Department refused to perform a safety inspection without an upfront payment, despite the vehicle having exposed wiring in the steering column and part of an active federal safety probe. As a small business owner (Maid To Sparkle) grandmother who transports a [XXX] daily, I am now stranded with a vehicle that is unsafe to drive due to a documented a manufacturer defect. While at the dealership I was simultaneously on the phone with Jeep Customer Care. Despite the vehicle being under federal safety investigation for the exact ghost breaking I am experiencing both the dealer and corporate representative denied assistance and refused a safety inspection without an upfront fee This shows a coordinated refusal to address a documented safety defect.

The contact owned a 2021 Jeep Cherokee. The contact stated that there was an abnormal sweet/alcohol smell in the vehicle. There were no warning lights illuminated. The vehicle was taken to an independent while in the process of performing a stress test drive. There was a popping sound from the ignition, and it stopped on the interstate. Upon opening the hood, he noticed smoke and flames, and the vehicle fully ignited and caught fire. The fire department was on the scene to extinguish the fire and determined that the cable installation or hose installation failure of equipment/leak resulted in an electrical fire. There was no reported crash, air bag deployment, or police report filed. The local dealer was contacted, who referred to the manufacturer and the NHTSA hotline. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 64,000. The vehicle was deemed a total loss by the insurance company.

Incident

Oct 23, 2025

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.

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.

The Jeep caught fire underneath while I was driving on the highway. There were no warning lamps or symptoms of the problem prior to failure. I saw flames come up over the front of the car and immediately parked and ran with my child. We could have died.The fire and stopped car in the middle of the highway could have caused a pile up of crashes. It is unknown what component or system failed and I don't believe it is available for inspection as State Farm decided not to move forward with inspection. They declared it a total loss.

While at a complete stop vehicle’s rpms went up and launched forward on its own. It continued to do so several times despite pressing the break pedal fully. Vehicle did the same thing only a couple of weeks after being purchased but I was unsure if it had been the vehicle or I eased up on the break a little too much. This latest time however it did it so many times that I was able to record it and share it with my dealership.

The first time it happened was 9/23/2022. I was accelerating away from a traffic light, going to make a left turn, and warning lights came on and the car didn't want to go. The orange check engine light was on, there was a red symbol of a throttle venture and several other orange lights and the car was in limp mode. I restarted the car and the red venture light was out and only the check engine light was on and the car was out of limp mode. A week later 9/30/2022, the same thing happened. I was making a left turn at a light and the lights came on and it went into limp mode. I restarted the car and it was out of limp mode. Just up the street I was making a left turn across traffic and as I went the car again went into limp mode with the red and orange lights on. This time it left me in the middle of a 3 lane road trying to get across. I was almost T-Boned. I took the car to the dealer and they were unable to duplicate the problem. They had the car for a week., 20/5 - 10/12/2022. Then today, 10/18/2022, the same thing happened. The red venture light came on, the orange check engine light came on and some other warning lights came on. One was the traction control light in orange. I was making a left turn out of a shopping center at a light and as I started to go I almost stopped when the car went into limp mode. I tried restarting 3 times and the lights stayed on. I drove it to the Jeep dealer and had them read codes before it was shut off. This could be very dangerous if it happens as someone is trying to cross traffic or on the highway.
