2019 Jeep Cherokee: misfire or rough idle

Filed Jun 12, 2026 · Engine · 95,000 miles · MN

The contact owns a 2019 Jeep Cherokee. The contact stated that while driving approximately 65 MPH, the vehicle suddenly lost motive power following a loud screeching sound. The Check Engine warning light illuminated, and the vehicle started to misfire upon depression of the accelerator pedal. The contact managed to drive the vehicle to the local mechanic, where diagnostic testing revealed a misfire in cylinder #3. Further investigation confirmed internal cylinder damage, which resulted in total engine failure. The mechanic ordered a replacement engine long block from Albany Chrysler Center, Inc. (34650 225th Ave, Albany, MN 56307). After a two-month wait, the part arrived; however, the dealer was sent a complete engine assembly instead of a long block, which required additional repair costs. The manufacturer has not yet been notified and the vehicle remained unrepaired. The failure mileage was approximately 95,000.

The vehicle experienced a sudden engine failure while driving. Prior to failure, a flashing check engine light appeared along with severe engine misfire, sputtering, and loss of power. The vehicle became unsafe to operate and required towing. The vehicle had recently undergone recall service (PTU recall 01C) at an authorized dealership. Shortly after that service, the engine failure occurred. It is unknown if the recall repair contributed to the failure, but the timing is notable. The vehicle has been regularly maintained according to manufacturer recommendations. A dealership has inspected the vehicle and indicated that the engine requires replacement due to internal failure. The failure has been identified as involving piston #2, with coolant intrusion into the cylinder. This condition is consistent with loss of compression and internal engine damage. Numerous other owners of similar vehicles have reported nearly identical failures, frequently involving piston #2, suggesting a potential pattern or common defect affecting that specific cylinder. The sudden loss of power while driving created a safety risk, particularly if this had occurred at higher speeds or in heavy traffic. This issue appears similar to other reported problems involving 2019 Jeep Cherokee vehicles equipped with the 2.0L turbo engine, including misfire conditions and potential loss of compression leading to engine failure.

The engine has failed. The cylinder has low compression and the engine misfires and can no longer be ran. When the incident first happened we were left on the side of a busy interstate 3 hours away from home. Upon doing some research MANY other Jeep Cherokee owners for my years make and model have reported the same problem. There was ABSOLUTLEY no warning before the issue arose. We were then left with a hefty car loan for a vehicle that no longer runs. We got two opinions from two mechanics of which both said it’s a manufacture problem and that we did not cause the issue. It would cost 8k or more to fix the problem.

Re: Safety Concerns Regarding Jeep Cherokee 2019 Engine Misfire To Whom It May Concern, I am writing to report a significant safety issue regarding my Jeep Cherokee 2019. I bought the car new and have always serviced it in the official dealer. Recently, my vehicle began to misfire while I was driving, which caused me to feel unsafe and concerned for my safety. Upon taking my vehicle to the dealership, I was informed that the engine needed to be replaced. The dealer service report showed that the cause of the issue was a P0302 cylinder 2 misfire code, and that the engine was misfiring. Additionally, the report indicated that there was only 75 psi compression on cylinder #2 and 40% cylinder leakage. My car had only slightly exceeded the mileage limit of the manufacturer's warranty, which was for 60,000 miles, at 60,800 miles. However, the warranty did not cover the cost of the engine replacement, which was approximately $13,000. This safety issue is concerning because the engine misfire could cause the vehicle to suddenly stall or lose power, which could result in a serious accident. Additionally, I am disappointed that the warranty did not cover the necessary repairs, and I was left to pay for such a significant expense for a vehicle that is only a few years old. Furthermore, the manufacturer has offered to pay only 50% of the cost of a new engine, which I do not believe is fair or reasonable. I request that the manufacturer reconsider its decision and replace the engine at no cost to me. I urge the federal safety agency to investigate this safety issue with Jeep Cherokee 2019 engines to ensure that other drivers do not experience the same safety concerns. I believe that it is critical to ensure that vehicles are safe for drivers and passengers to operate. Thank you for your attention to this matter.
