Subject: Safety Complaint – 2021 Jeep Wrangler 2.0L Fuel Pump Failure (Loss of power while driving.) I am filing this complaint regarding a 2021 Jeep Wrangler equipped with the 2.0L engine due to what I believe is a significant safety issue involving the fuel pump. The fuel pump has failed, making the vehicle unsafe and/or inoperable. A sudden fuel pump failure can cause the engine to lose power or stall without warning, creating a serious safety hazard, especially when driving at highway speeds, in heavy traffic, or while crossing intersections. A loss of engine power in these situations places both the driver and surrounding motorists at risk of a crash. What is equally concerning is that the replacement fuel pump is currently on a national backorder, with my dealership estimating approximately 45 days or longer before the part will be available. This suggests that many owners may be experiencing the same problem and that replacement parts cannot keep up with demand. As a result, my...

Vehicle received federal recall 01A service (high pressure fuel pump replacement) at an authorized Chrysler/Jeep dealership on 05/14/2026 at 97,055 miles. I drove the vehicle normally for approximately two weeks (roughly 950 miles), then parked it in my garage awaiting a separate warranty part for the intake manifold. On 07/03/2026, during that warranty repair at the same dealership at approximately 98,000 miles, the dealership’s own technician discovered a diesel fuel leak at the fuel injector supply tube. This line must be disturbed to access and replace the high pressure fuel pump during the recall procedure and is a single-use component. No fuel leak or fuel system issue existed or was documented before the recall service; the vehicle was scanned at the same dealership at intake and the only issue found was an intake manifold valve actuation code unrelated to the fuel system. The leak was confirmed by the dealership and the component is available for inspection; I have requested th...

I am filing this safety complaint regarding my 2021 Jeep Wrangler Unlimited Sahara Altitude. The vehicle is experiencing a fuel gauge/fuel reading malfunction. The gauge does not accurately reflect the amount of fuel in the vehicle, which creates a serious safety concern because the vehicle may run out of fuel unexpectedly while being operated on public roads. This defect places me and other drivers at risk, especially if the vehicle stalls in traffic, on a highway, or in an unsafe location. I am requesting that NHTSA review this issue as a potential safety defect.

My 2021 Jeep Wrangler 3.0L EcoDiesel experienced a failure of the engine oil cooler that allowed engine oil and engine coolant to cross contaminate. The oil cooler on this engine sits between the oil and coolant passages, so an internal failure of that component mixes the two systems. The failure first occurred in September 2025 while the vehicle was in use, and coolant intrusion into the oil system has recurred in 2026. This condition is a safety concern because it can cause engine overheating and sudden loss of engine performance or engine failure while driving. On one occasion the vehicle overheated within approximately one mile of leaving a service facility. Low oil pressure was also observed (as low as 9 psi), which risks engine damage and loss of power in traffic. The manufacturer (FCA US LLC / Stellantis) initial XXX November 7, 2025 the arbitrator ruled in my favor, finding the oil cooling system failure "was more likely a result of a Manufacturer defect" and that my modifica...
