2021 Jeep Wrangler

The Office of Defects Investigation (ODI) has identified 68 Vehicle Owner Questionnaire (VOQ) reports for model years (MY) 2021 through 2024 Jeep Wrangler 4xe vehicles alleging a loss of motive power. Recall 22V-865 was issued by the manufacturer to address an engine shutdown condition in certain MY 2021-2023 Wrangler 4xe vehicles. The complaints noted here contain both post recall remedy failures and failures in vehicles not included within the scope of 22V-865. An analysis comparing complaints received before the issuance of recall 22V-865 and complaints outside the scope of the recall has been conducted. The results show the current complaint rate is higher in the out of scope vehicles than it was for vehicles that were later covered by the recall. ODI is opening this Recall Query (RQ) to assess the severity of the alleged defect in vehicles not included in recall 22V-865.ODI will also assess the scope and remedy effectiveness of the recall. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337

On September 6, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24024 to investigate allegations of engine compartment fires in model year 2021-2023 Jeep Wrangler and Gladiator vehicles. Most reports described fires starting on the front passenger side of the engine compartment while the vehicle was turned off, with several originating specifically at the electrohydraulic power steering pump's electrical connector. Following the opening of the investigation, ODI sent an information request letter to the vehicle manufacturer to assess the cause, scope, and frequency of the alleged defect. Additionally, ODI continued to receive reports of vehicle fires with a likely origin at or near the power steering pump. Throughout this investigation, ODI continued to discuss these new reports and the information request letter response with the manufacturer. On June 4, 2026, FCA issued recall 26V363 to address power steering fires caused by high electrical resistance at the pump's connector. Recall 26V363 includes the 781,459 vehicles identified in the opening resume of this investigation and expands the population to include all 2021-2025 Jeep Wrangler and Gladiator vehicles produced between June 24, 2020, and December 2, 2024.This recall directly covers the vehicles and issues examined in this investigation. Accordingly, ODI is closing this investigation and is not requiring FCA to provide any additional information about this issue at this time. The Agency will continue to monitor field performance and reserves the right to take additional action if warranted by future circumstances.

On September 20, 2026 I came outside to find the charging port on my 2021 Jeep Wrangler 4xe smoking and extremely hot to touch. It had been plugged into a level 1 (120v) charging cable to charge overnight outside our garage. I immediately unplugged the charging cable and placed it on the ground. While inspecting the charging port on my Jeep I found the pins charred and melted plastic inside the port, possibly caused from electrical arcing. I made an appointment with the dealership the following day but had to wait until October 26 to be seen. During the appt on Oct 26 they completed software updates and confirmed the charging port had been destroyed and complete replacement was necessary due to the severe high voltage thermal incident. They quoted $1055 for replacement, denying warranty coverage due to mileage (137,000 miles). I believe this malfunction represents a severe malfunctioning defect in the high voltage charging infrastructure of my Jeep 4xe vehicle that put my vehicle, home, and family at risk.

At 47000 miles the oil cooler cracked, although the technician stated it did not cause the crankshaft: harmonic balancer pulley to be damaged, the mat issue did occur and documentation from other sources state one can cause the other. Replacement cost was substantial for a low mileage vehicle. Documented issues with the oil cooler failing on Jeep Wrangler JL, specifically the 3.6 L engine is easily obtainable. The dealership admitted replacing a lot of them. This is a manufacturer defect that should be resolved.

When driving about 50 miles per hour on the highway, it felt like my engine suddenly gave out and my dash turned off. When it came back in, there were multiple indicator lights and a message that read "Pull over safely and shift to Park." I did just that, but after that I couldn't get the car to turn back on or shift out of park. I had to have to towed to the dealer and it has been there since 10/13.

Incident

While towing a utility trailer on the highway, the vehicle suddenly lost acceleration and could not maintain normal power while the driver was attempting to pass a semi-truck. During the incident, the semi-truck contacted the trailer and shredded one of the trailer tires. Three occupants were inside the vehicle. No injuries occurred, but the incident created a serious risk of a fatal collision. The vehicle has repeatedly displayed “Service Electronic Stability Control” and other warning lights, together with loss of power and transmission hesitation/slipping. The same concern has been reported to the dealership during approximately three service visits. The dealership previously replaced the air filter and attributed the warning lights to it, but the condition returned. Dated videos show the warning condition before and after that repair. The vehicle is currently back at the dealership for the recurring safety concern.
