Jeep Cherokee check engine light comes on

Filed Oct 30, 2026 · Engine, Fuel system · MO

My jeep stalled while attempting to accelerate from a stopped position at a stop light at a busy intersection on or around June/July 2026. The car remained on, the gear shifts were moveable, but the vehicle would not move despite pressing on the gas. I scheduled a tow. After ten minutes, it randomly accelerated about a block before stalling again. This continued about two more times as I tried to get the vehicle out of the middle of the road. The car then overheated and I was able to park it a few blocks away at my mom's house. In August/September 2026, I had the car towed to Complete Automotive, and Corwin Jeep for inspections. Progressive Insurance also inspected the issue and ruled out any residual effects from a 1.25.25 parked car front end hit and run collision. Complete Auto found an empty coolant reservoir, oil and coolant leaks, drive belt issues, PTU code, and warning light indicators; Corwin found PTU code and recommended a transfer case. The exact cause remains unknown. The vehicle has had ongoing hose and overheating issues since the day of purchase in 2018; and has underwent hose and radiator replacements that have not seemed to properly fix the issues surrounding sloshing noises, shuddering, shaking, grinding, intermittent lightening, brake fluid, oil, and coolant leaks, and overheating and engine light. Immediately before the vehicle stalled, there were no warning lamps; those messages indicating overheating lit up while attempting to move myself and the car to safety. The unexpected loss of propulsion presents a serious collision risk, especially in traffic, in rush hour at a busy intersection. The recurring overheating and coolant loss also create risk of sudden failure while driving, which has happened on a busy highway requiring repairs. These problems and safety risks have continued despite substantial repairs and repeated dealership inspections. The vehicle remains inoperable awaiting repairs at the Corwin Jeep Dealership.

While driving my vehicle, the check engine light came on after driving for about 10 minutes. It remained on and I called the dealer and they said that I should bring the vehicle in to be checked. They looked at the check engine light and said it was probably because the gas cap was not on properly. I do not have a gas cap so the turned it off and said I should be ok. It came on again and they said they would have it checked further. After further investigation the discovered a loose flap associated with the cruise control and adjusted the flap. I was told if it came on again it would need to be replaced. The light came on again and I took the vehicle in to have it replaced. It has not yet been repaired. The engine light comes on and even goes out while driving.Generally the light will come on and stay on for a few days and go off but it happens and I have not had one vehicle for more than a few months. I believe another problem is being generated from this because now I am having problems with the vehicle jerking because the vale has not been replaced.

The contact owns a 2019 Jeep Cherokee. The contact stated that the vehicle was initially taken to the dealer because the check engine light illuminated and the radio became very hot. The dealer replaced a valve and installed a new screen, which temporarily resolved the issue. Months later, the failures recurred, and the transmission was replaced. The vehicle was returned to the dealer for a software update. During a later visit, the dealer diagnosed the vehicle with a failing transmission gasket, a rear differential leak, an engine oil leak, and a failed battery requiring replacement. After the contact heard a loud scraping noise, the vehicle was returned to the dealer, who performed a rear differential fluid change but stated no mechanical failure was present. The contact returned the vehicle to the dealer after a "Service 4WD" warning light illuminated. The dealer replaced the Power Transfer Unit (PTU) motor, despite claiming the PTU was unrelated to the failure. The contact stated that the transmission assembly, PTU motor, gaskets, and other essential powertrain components were all replaced within a one-year period. The contact stated that the engine consistently emitted an abnormal unknown odor. The manufacturer was notified of the failure. The dealer confirmed the failure. The failure mileage was 38,000.

On October 1, 2026, at approximately 1,968 miles, my 2026 Jeep Cherokee experienced a serious powertrain failure. I began driving home from work and the vehicle initially moved without severe shaking. While traveling on the highway at approximately 70 mph and then accelerating uphill, the vehicle progressively lost power and began shuddering violently. The check-engine light began flashing while the red Electronic Throttle Control warning remained on screen. The vehicle appeared to enter a limp mode and I had significant difficulty maintaining speed and climbing the hill. A highway patrol officer followed me with his lights and siren and with his escort I was able to safely reach the next highway exit, but I was concerned that the sudden loss of acceleration could have resulted in a crash, particularly in highway traffic. The dealership performed a diagnostic scan after arrival and the service advisor told me the vehicle had multiple pending faults involving the electronic throttle body, engine misfires, fuel mixture, and other engine-management systems. The dealership has continued testing the vehicle and I was subsequently advised that testing showed severe internal engine damage affecting three of the four cylinders, described to me as three cylinders having “a hole,” and that a replacement engine may be required. The technician is consulting Jeep/Stellantis regarding additional testing, possible teardown, and repair authorization. The exact internal component that failed and the root cause are still being determined. My concern is the sudden loss of power at highway speeds, violent engine shuddering, and malfunction errors on a new vehicle under 2000 miles.

The transmission light went on. Car was brought into dealership two times while still under warranty. They did not have a fix and PTU was on back order for over a year in 2017. I am now resorting to pay out of pocket. I had a PTU shipped from a Jeep dealer in Louisiana. PTU from them was not new but had come off another car and was charged $2,300. I sent it back because it was used at that time I was working and was going to pay out of pocket. I was not going to pay to install a used transmission. Regardless there is as no fix. Then in May of this year the check engine light came on. This was another problem that the Jeep dealership cannot fix. Now I have a paid for car that cannot be driven because it cannot be smogged. It has the Pentastar V6 engine. There is no fix for either problem I understand and I am retired and cannot afford these repairs. I asked the manufacturer in writing to buy the car back and they said no. Can I get some help? This was going to be my last car. Jeep dealer offered $200 for the car. My all weather tires are worth more than the car. I’ve changed oil on time using synthetic oil and have otherwise taken good care of this car. I thought they would come up with a fix for the transmission is why I waited so long. Everything that is wrong is the manufacturer’s product defect. Also, I have documentation on everything I just wrote you. Please help me!!! [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving after work on 53S my jeep decided to only go 5mph engine light turned on among other light. Svc 4wd. Had to pull over the interstate shoulder that’s under construction and had very small space to park without getting hit by others.
