2022 Jeep Wrangler: fuel pump failure

Filed Jun 27, 2025 · Electrical, Engine · FL

The vehicle experienced multiple serious fuel system failures, including a failed fuel injector and high-pressure fuel pump. After these components were replaced, it was confirmed that fuel was still entering the engine crankcase. At no point did the vehicle trigger a “Check Engine” light, oil dilution warning, low oil pressure alert, or any hybrid/electric powertrain. This represents a critical safety & reliability issue. Fuel dilution of engine oil can: severely degrade lubrication, increase crankcase pressure, and/or lead to internal engine failure or fire The lack of any warning or diagnostic code suggests either: a software calibration issue in the ECM/BCM that failed to detect the problem, a sensor failure, and/or a defect in the onboard diagnostic system itself. This could indicate a broader defect affecting the safety of the 4xe platform and request investigation. This failure delayed necessary service and put both vehicle and occupants at risk.

We have 2 2022 Jeep vehicles with the EcoDiesel engines in them (a Gladiator and Wrangler) that we purchased in 2022. I am filing a case for each of them on this site. In April 2023 there was a recall of the fuel pump on the 3.0 EcoDiesel and to date the problem has not been rectified for either of my vehicles. We have made notification to the dealership that we want to get this done but they say they do not have the parts in stock to do it. The dealership said they only get 1 fuel pump a month to replace and we are waiting and have been waiting for about a year since we notified the dealership for this safety issue to be rectified. I am filing this complaint as directed by the federal safety agency website because I feel this issue has not been handled in a timely fashion and I believe that it is irresponsible of Jeep to not rectify this in a much quicker fashion. Each time we call the dealership we are told they do not know when it will be rectified.

Upon purchase of the Jeep, within 8K miles, the fuel pump went out and left me stranded. Now, at 27k miles, the car has been undriveable for 4 months. The engine will not accelerate, causing near collisions on highways. Over 13k in repairs are currently in place and there is still no resolution.

Vehicle has a recall on it for the high pressure fuel pump. I have been told by the dealership this part is on back order and can take 12 months before they can fix the High Pressure Fuel Pump. I called a second dealer ship and they also told me it could take 3-12 months before they could fix it due to limited supply of the part. DMV will not give me my car tags until this recall is remedied.

My vehicle has a recall for the High pressure fuel pump. While driving the engine light and cruise control light will turn automatically and then go away consecutively. Yes, the issue has been confirmed and inspected by the manufacturer and the dealership in which I purchased my vehicle. The vehicle will stall when running or randomly turn off and smell like smoke. I have made 3 appointments in which the dealership will advise me to drop my vehicle off and once I arrive they tell me they do not have the parts. I called the manufacturer and they advised they receive the parts every 7 days. I have contacted the dealership and I will not get a response. I'm scared for my safety and others. The contact stated she would appreciate a response and assistance with a recall for the vehicle.

In April 2023 I was advised via a letter from Mopar of an important recall concerning the “High Pressure Fuel Pump” in my 2022 Jeep Wrangler. The correspondence warned that a failure of the fuel pump could result in a catastrophic crash without prior warning. The letter also indicated that “a remedy for this condition is not currently available”. Having not heard from the manufacturer for several months after receiving the recall notice, I contacted the recall hotline in July to request an update. The agent I spoke with indicated that parts to address the recall are not yet available, and she was unable to provide me with an estimated timeframe for the repair. The lack of a remedy, despite the implied severity of this recall, leaves me deeply concerned with the safety of my car. I rely on my vehicle for daily transportation and feel as though I’m taking a risk driving it. The car is less than one year old and has only 6378 miles on the odometer.
