2022 Jeep Gladiator engine problems

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.

The camshaft went out, along with the rocker arms, cam phasers, there is a box on the passenger side wheel well that goes out and will not allow the truck to shift or go into park. There is now something wrong with the automatic start/stop as the light continues to be on in the dash. Things started to go out as soon as the warranty expired… The truck has 80kmi. We fix one problem only for more to pop up. We purchased the jeep brand new and everything since it has had one problem after another.

Component Affected: Engine – Camshaft and Rocker Arms Summary of the Problem: My 2022 Jeep Gladiator experienced a failure of the camshaft and rocker arms due to scoring on the camshaft. This issue occurred at approximately 52,000 miles. The vehicle is currently inoperable (on and off flashing check engine light) Dealership gave me the vehicle back to drive while awating parts for repair. The required components are on national backorder with an estimated delay of over 4 weeks, leaving me without a functioning/safe vehicle. Safety Concern: This failure occurred without warning and could have led to a dangerous situation if it had happened while towing. I use this vehicle to tow a 3,500 lb camper, which is well within its rated towing capacity (6,500 lbs). The sudden loss of engine performance could pose a serious safety risk, especially on highways or in remote areas. Additional Notes: I am reporting this issue because I have learned that other Jeep Gladiator owners have experienced similar camshaft and rocker arm failures. This may indicate a broader defect in the engine design or materials. I believe this issue warrants investigation for potential recall or manufacturer accountability.

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)

Engine began making a ticking noise and quickly began misfiring and displaying error messages. Dealership diagnosed issue as a camshaft failure, and which is a very common issue on the 3.6L V6. Issue happened on a rural road at night, but could've been a serious safety issue if it had happened in a different setting.
