2022 Jeep Gladiator Engine Problems

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 NHTSA 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 NHTSA 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)

I parked my car in the garage. It was turned off. I left the garage door open and went inside. After approximately 5 minutes I heard a car horn sounding. I went outside to check and saw flames coming from the passenger side of the car. I got the hose to put the fire out, and my neighbor called 911. The flames grew quickly and were growing. Soon the flames were on both sides of the car. Both the police and fire department arrived. The fire report indicates that the fire started in the engine area of the car. The car is now in the possession of my insurance company. My safety and the safety of others was at risk due to the fire. I was burned on my arm, neck and head. The car was completely burned. My insurance carrier inspected the car. The fire department said the fire started in the engine area.

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.

Warning lights come up on the dashboard often (brake failure, airbag failure, steering failure, start/stop needs servicing, transmission needs servicing, pullover safely car will turn off, car not in park but it is and won’t turn off) the car turns itself on and off all day. From the beginning the vehicle had electrical issues, not connecting to my phone or Bluetooth, the screen not working, locking and unlocking only working from the key not using the passive entry and having to start the push button by pushing it with the key or it wouldn’t work, it’s gotten progressively worse and now mid drive it will slam to a stop like it hit a wall, flash all the system failure lights then just all the instrument panel lights, it turns on the windshield wipers, the hazards do not work, the headlights start flashing independently etc. it will not turn off or on. It has been towed to the shop twice for this where they replace the two batteries/fuse array and say they can’t get it to happen again but see the codes on the box. It’s spent a combined 140+ days in the shop at this point where I have to fight days to get a rental. The slamming to a stop mid drive is so harsh not only am I almost rear ended but also it’s torn my shoulder forming a cyst that I’ve had trigger point shots and physical therapy for and might need surgery yet they still refuse to buy it back. I have videos.

Our 2022 Gladiator has 1,758 miles on it and no modifications. It was last driven about two weeks ago. It burned to the ground [XXX] while parked next to our house. The fire started in the engine compartment. There were no warnings of symptoms and our jeep app showed everything was normal when last driven. It was investigated by the VRFA and I am waiting for their report. Insurance has not yet inspected. We reported it to the dealership we bought it from. On the [XXX] website, there is another 2022 Gladiator, also low mileage, that also burned to the ground while parked. That person's insurance stated that they believe it burned due to a manufacturer defect but there are no recalls.

My 2022 Gladiator with only 2700 miles on it locked up at a stop light. Every light on the dash was blinking, and the wipers came on. I couldn’t move the shifter, or turn the Jeep back on. Hazard lights would not come on initially. Not being able to move the vehicle or turn on hazard lights on a busy 6 lane road was extremely scary. I have never had a vehicle do anything like this before. I had it towed to the dealership. I explained what happened and they had never heard of this before. I have read of it happening on social sites and forums. I feel uncomfortable driving it even if they repair it. I bought this vehicle less than 60 days ago as of this message.
