Should I buy a 2021 Jeep Gladiator with documented fuel system problems?

Depends on the price and the specific vehicle. Documented fuel system issues should be priced into the purchase — if the seller is asking full retail, negotiate down by the expected repair cost. A pre-purchase inspection from an independent shop tells you whether THIS specific vehicle has already shown the symptoms or not.

The failure pattern owners describe

Buyer takeaway: Twelve 2021 Gladiators have reported fuel system issues, with several experiencing dangerous power loss or stall at highway speeds linked to NHTSA Campaign 22V767000—and Jeep has had chronic parts unavailability for the recall repair. If you're shopping for one of these, confirm recall status and insist on completion before purchase, or walk away.

Of twelve complaints in this cluster, five owners experienced actual fuel system failures while driving. The most serious: fuel pump failures causing loss of engine power or complete stall at speeds between 55 and 75 MPH, with no warning lights and no restart capability on one vehicle. Owners reported intermittent power loss that recovered minutes later, sudden deceleration despite pressed accelerator pedal, and abnormal engine sounds preceding failure. One stall occurred at just 14,000 miles; others between 40,000 and 50,000 miles.

Seven complaints involve owners who received NHTSA recall notifications (Campaign 22V767000) but cannot get the repair done because Jeep's parts have remained unavailable for an extended period—dealers and the manufacturer both confirm this repeatedly. These owners have not yet experienced failures but carry the known defect.

One complaint involves multiple fuel system components (pump, injectors, filter) all faulty at 40,000 miles. Another occurs at only 165 miles—a DEF tank and sensor failure producing a dashboard warning that the vehicle would fail to start in 200 miles, with parts backordered.

The manufacturers were made aware; owners received recall notification or contacted dealers. No field repairs were completed on most vehicles.
