High pressure fuel pump failure
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, the federal safety agency determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow the federal safety agency to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.the federal safety agency.dot.gov/owners/Searchreference using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337

What 2021 Jeep Gladiator owners say
Most recent owner complaints, unedited.
The vehicle was bought in CA and hasn't had any issues till about after 3-4 yrs later. 1) Adaptive cruise control / emergency braking system / forward collision notification will occassionally state "not availble/unavailable" or "visibility" is not available and to clean windshield, but the windshield is not dirty or obstructing the camera. 2) The fuel emission system has had several diagnostic codes referring to the gas gap or fuel sensors. Vehicle is boggs down/loses power and starts ideling roughly and acts like it wants to shutdown and has shutdown. I've had to get vehicle towed twice for this issue. Replaced gas gap and still had issues. Then they went away for a few months, but now I am getting a diagnotic code stating that the fuel tank gas sensor is causing the check engine light.
7/5/2026. Driving home on the highway the Jeep went into limp mode and shut down. The Fault flashed on the screen for about 15 seconds (Throttle Body Falut) Problem is there is no warning when it happens. It just shuts down. This creates a "REALLY SERIOUS HAZZARD" This time it did register a fault on the computer and we were able to pull it off the reader. The Fault reads as follows: POOAF In looking it up on this is a manufacuring problem that can be caused by a little dirt, Can be caused by hot weather. THIS IS NOT SAFE! MY I REPEAT, THIS IS NOT SAFE! This should be recalled and Fixed as I am sure this shutting down on the Hiways and Interstates have killed people that were not able to deal with a situation. Please force a recall befor lives are lost!
Every time I fill up my gas tank, the fuel doesn’t shut off in time from the pump and gas comes backward up the filler neck, onto the side of my jeep.
Bought this vehicle with 27,000 miles on it. While driving on the interstate with heavy traffic. (Doing Highway speeds) All the sudden the power plant shuts down. It happend at 27,500 miles and happened again at 37,000 miles. It has done it to me four times now. Twice with heavy semi trucks bearing down on me and my family. This was a very UNSAFE situation. The Fault on the screen comes up momentarily and states "Capture Throttle Body Fault." and all power is lost to the throttle. SERIOUS SAFTETY ISSUE. as loosing power on the interstate at 75 miles an hour. I believe JEEP the company should fix this issue as I know for a fact I am not the only individual experincing this problem! Please feel free to reach out to me if you need further information. There was not a crash,fire or injury due to the ability to get off the road and into the apron of the interstate. In a higher traffic location this could be catistrophic. PLEASE PLEASE PLEASE talk this issue seriously as I am convinced this has caused others to wreak. Thanks and have a great day

Additionally, there was a message indicating 200 miles were remaining before the vehicle would fail to start. The vehicle was taken to the local dealer, where it was diagnosed and determined that the tank and sensor needed to be replaced; however, the parts were on backorder. The vehicle was not repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 165.
Mopar recall Z96 posted October, 13th 2022 for high pressure fuel pump. My local dealership stated parts for replacement of the high pressure fuel pump did not become available until November of 2023. They inspected my vehicle November 21st, 2023 and determined the high pressure fuel pump was to be replaced under mopar recall Z96. Dealership ordered parts at that time. On to March 4th, 2024. I reach out to local dealerships service and parts departments. Not all parts had been received and there was no understanding of when the rest of the necessary parts would arrive. May 7th, 2024. It is now nearly 1 year and 7 months since this recall was released and nearing 6 months since my local dealership stated they ordered parts to replace the fuel pump. My local dealership continues to have no understanding or intention of securing the remaining parts necessary to complete this recall. This amount of time is unreasonable for a part that if it fails will cause loss of engine power and may cause a fatal crash.
