2020 Jeep Cherokee engine problems

“ENGINE LIGHT COMES ON, WHENEVER YOU ATTEMPT TO ACCELERATE FROM A STOP (LIKE A TRAFFIC LIGHT), THE VEHICLE WILL COAST INTO THE INTERSECTION, CAUSING A TRAFFIC HAZARD. IT HAS DONE THIS MULTIPLE TIMES. AT 60,300 MILES, DEALERSHIP TOLD ME THAT ENGINE WAS NOT COVERED. I PURCHASED A NEW ENGINE, WHICH NEVER FIXED THE PROBLEM. 5 DIFFERENT TIMES THEY RESET DASH BOARD, BUT THE IT CONT'D BEFORE I CAN GET HOME. DEALERSHIP GASLIGHTS WITH THEY COULD NOT GET PR0BLEM REPEATED. BUT AS SOON AS WARRANTY EXPIRE(EED), DEALERSHIP ADMIDES CAR NEEDS 2ND NEW ENGINE. $9K.”

“Like previous model years, the 2 L Turbo engine started buring excessive oil (more than 1 quart per 500 miles). Two mechanics have indicated that engine and turbocharger need to be replaced. Both said that this engine is same as previous model years for which recalls were initiated.”

“To Whom It May Concern, I am submitting this complaint regarding a catastrophic Power Transfer Unit (PTU) failure on my Jeep Trailhawk that has rendered my vehicle undrivable and raised serious safety concerns. While driving, my vehicle experienced a sudden PTU failure that resulted in a loss of safe vehicle operation. The failure was severe enough that the vehicle could not be driven and had to be towed to an authorized Jeep dealership for diagnosis and repair. The dealership has confirmed that the PTU has failed; however, there is currently no available repair solution or replacement part to permanently correct the issue. As a result, my vehicle remains out of service indefinitely. In addition to the safety concerns related to this failure, I am extremely concerned about the manufacturer's response. Although Jeep has acknowledged the failed component, I have been informed that I must pay out of pocket to have the same defective PTU reinstalled temporarily until a permanent repair becomes available. Jeep has stated they may reimburse me at a later date, but they are requiring that I bear the upfront cost for a known faulty component. Furthermore, neither Jeep…”

“On September 23, 2026, my wife was driving our 2020 Jeep Cherokee Trailhawk on I-65 South at mile marker 105.1 when the vehicle lost drive power and could no longer be driven. She became stranded on the side of the highway, and I had to pick her up. The vehicle also rolled while the gear selector was in PARK. We had it towed to Tom O’Brien Jeep dealership in Greenwood. Our vehicle is included in open safety recall 40D, NHTSA campaign 26V-290, involving the power transfer unit (PTU). The loss of drive power and rolling in PARK match the failure symptoms described in that recall. The specific mechanical cause still needs to be confirmed by the dealership. The Mopar recall lookup shows the recall is incomplete, the remedy is under development, and repair parts are not available. The vehicle is currently at the dealership. I am reporting an actual highway loss-of-propulsion incident and the vehicle rolling while in PARK. I am concerned about the risk of a crash or injury and the lack of an available recall remedy. Please document this incident under the existing recall and review the manufacturer’s response to vehicles that have already experienced these failures.”

“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.”

“The contact owns a 2020 Jeep Cherokee. The contact stated that while the vehicle was parked, the contact was informed that there was an oil leak underneath the vehicle. The contact was unsure if the oil was coming from the vehicle. The vehicle was then taken to the residence and parked, and the contact observed puddles of oil underneath the front of the vehicle. The vehicle was towed to a dealer to be diagnosed. The dealer stated that the radiator, engine, turbo, thermostat, torque converter, and other unknown parts needed to be replaced, and that the engine control valve was possibly stuck, resulting in oil and coolant contamination. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 115,000.”
