The failure pattern owners describe
Owners of 2021 Jeep Wranglers report fuel system failures tied to NHTSA Campaign 22V767000. The most serious complaint is high-pressure fuel pump failure, which causes sudden engine stalling without warning lights, leaving owners stranded and unable to restart. In one incident, the vehicle lost power steering and braking when it stalled at 25 mph. Other owners describe intermittent stalling from traffic stops, loss of motive power on hills at highway speed, and inability to accelerate above 30 mph. Failures occur between 15,000 and 39,000 miles.
A secondary issue reported is fuel leaking from the rear passenger side with diesel odor, tied to a faulty fuel filter housing and electrical connector. One owner also reported an oil pressure alert message that dealerships traced back to the recall.
The universal complaint across 25 reports is parts unavailability. Dealers repeatedly confirm the high-pressure fuel pump is on national backorder. Owners allege the manufacturer exceeded reasonable repair timelines and, in some cases, told owners parts could not be ordered unless the vehicle was physically at the dealer or had already failed. One owner repaired the fuel leak themselves when the dealer refused to complete the work without available parts.
