2022 Jeep Gladiator: sudden loss of power

Filed Aug 5, 2026 · Electrical, Engine · TN

On July 30, my 2022 Jeep Gladiator Rubicon suffered an extremely dangerous, unexpected complete electrical and engine failure while in operation. The vehicle abruptly shut down without any warning, causing an immediate loss of power steering and power braking. Prior to and during this shutdown, diagnostic codes associated with lost communication were triggered, (Lost Communication with Transmission Control Module). A total loss of vehicle power and primary control systems while driving presents a severe, unacceptable safety hazard that places passengers and surrounding traffic at immediate risk of a high-speed collision or severe injury. Given that this model has low mileage (approximately 23,000 miles) and is under factory warranty, a catastrophic system shutdown like this indicates a critical safety defect within the electrical or powertrain control modules. I strongly urge the federal safety agency to formally document and investigate this life-threatening defect to ensure manufacturer accountability and prevent potential accidents.

Power steering failed without warning whilst driving at highway speed on i26, no warnings nor warning lights displayed. Vehicle remained operable, whilst difficult to steer I continued to next exit. As I slowed to a stop the power steering suddenly functioned again. This could lead to a fatal accident if this loss of power steering were to happen in a curve as the steering is exceedingly heavy without.

I am filing a safety complaint concerning my [Year] Jeep Gladiator (VIN: [Insert VIN]), which has experienced two high-pressure fuel pump (HPFP) failures—the latest occurring on [XXX]. This issue is directly related to the Jeep HPFP recall previously issued in 2023. After the first HPFP failure, the fuel system—including the pump, injectors, fuel lines, rails, filter, and tank—was replaced under warranty using Jeep’s reengineered HPFP component. The vehicle then sat at the dealership for five months awaiting parts and repair. Jeep also issued a compensation check, which I accepted based on the belief that the reengineered pump was a permanent fix. However, the same failure occurred again on [XXX], requiring a nearly identical replacement of the full fuel system. The recurrence of this failure, even after the “fix” Jeep implemented through the recall, raises serious concerns about the reliability and safety of the reengineered HPFP. I am concerned this is a systemic design flaw that has not been resolved. To date, my vehicle has been out of service for extended periods, and these failures could result in engine stalling, fuel leakage, or loss of power, increasing the risk of a crash or injury. Jeep has not provided adequate assurance that the reengineered part will prevent future failures. I am requesting that the federal safety agency investigate whether the reengineered HPFP provided through the recall is effective and whether additional action is needed to protect consumers. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The High-Pressure Fuel Pump (HPFP) failed while I was entering a downhill curve on a paved but narrow mountain road with no shoulder. The HPFP had been under an active recall, (Y78 / the federal safety agency 21V‑880) but every time we went in for service our Jeep dealership said a remedy was not yet available. When I asked if it was safe to drive, they said yes, continue to drive the vehicle and that they would call us when a remedy became available. Not very sage advice. The failure happened while we were on vacation in a remote area of New Mexico, four hours away from home. An unrecognizable warning light flashed but did not remain on. The engine remained running, but the HPFP failure caused a complete loss of power to the engine and transmission. Steering became difficult. I gently braked and coasted to a safe spot. Luckily that spot was a forest service road about a quarter of a mile from where the Jeep lost power. We had the vehicle towed to the nearest Jeep Dealership. They confirmed that the HPFP failed. It took 2 months for Fiat Chrysler Automobiles N.V. (FCA), and that dealership to address the HPFP issue. At the end of 2 months, they called and said the vehicle was fixed and ready. While driving home from the dealership a check engine light came on. That was [XXX]. We had the vehicle towed to our local Jeep dealership. Our dealership checked and said that there were still metal shavings in the fuel system. Our dealership and FCA have not found a solution and our Jeep is still inoperable and setting at the dealership.

The engine turned off while driving multiple times. Unexpected loss of engine power while at highway speeds forced us to maneuver to shoulder on busy highway in 70 mph zone. The dealership service team has not been able to reproduce the event or confirm it happened. The dealership service team inspected the vehicle. There were no warnings, lights, or symptoms before or after, that would have indicated the engine power loss event to us before or after the event occurred, in any of the occurrences.
