High pressure fuel pump failureOpened March 17, 2023, still open

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

I am filing a formal complaint regarding a FAILED RECALL REMEDY and subsequent CONSEQUENTIAL DAMAGE creating a severe fire hazard on my 2018 Ram 1500 EcoDiesel.In April, the official Z46 High-Pressure Fuel Pump (HPFP) recall repair was completed on my vehicle. Within one month of the repair, the Check Engine Light illuminated. I returned the vehicle to the authorized dealership (Lakeland Chrysler Dodge), where technicians dismissed the light as a minor "sensor issue" and stated it was resolved. Shortly after, the light returned a second time, and the dealership dismissed it again as a "programming error".Recently, the high-pressure fuel pump system suffered a catastrophic failure. The failure of the recall component directly caused severe consequential damage to the connected fuel return tube (Part #68229388AA), resulting in an active, dangerous fuel leak in the engine bay.Both the dealership and the manufacturer (Stellantis / Mopar Corporate, Case #98037315) are actively refusing to honor the federal safety recall mandate. They are trying to classify this as an out-of-pocket consumer expense, despite clear evidence that the initial recall remedy failed to correct the safety defect and directly destroyed adjacent fuel components. The vehicle remains unsafe to drive due to active fuel leakage.

>What Failed: There is a known issue with the fuel tank safety roll over value not functioning properly in many of the RAM vehicles. The valve stops functioning properly causing the fuel not to enter the gas tank when trying to fuel up. As you try to fuel, the gas comes spraying back out of the gas tank filler neck all over the side of the truck, my hands, and the ground causing risk of fire. >Person filling gas and all others in area at risk of fuel fire. >Problem is known by the dealer, and they charge customers to replace gas tank. Dealer has refused to issue a recall. >Defective component has been inspected by dealer, and they are aware of the known issue with roll over value not functioning. >No warning lamps or messages. Just a visual of the gas not being able to enter gas tank and pouring out onto myself and ground at gas station.

Prior to paying cash for this vehicle, I had the dealership connect it to an obd-11 scanner to ensure that there weren't any codes. (I wasn't aware at the time that if the codes were cleared prior to the test drive and before the vehicle was drove a certain amount of miles nothing would show up ) The truck seemed to be in ok condition. Before even making it 10 miles off the lot to my home the salesman who was to follow me in my new vehicle had issues and upon return to the dealership the truck had several "stored" and "active" codes which the salesman again cleared and told me to drive home and come back Monday with the truck the truck went into catastrophic failure and has been sitting since. The codes are P0365 indicating the entire PCM is failing or failed and P0606 an internal processor code which has to do with the computers not being able to calculate wheel speeds with the transmission and engine and how much gas to spray. And a P0616C EatC level 2 RPM performance code. There codes have to have been issues within the truck from my understanding to be both active and stored codes. I was sold a dangerous truck and they're not willing to give my money back or put me in a safe vehicle.

Rollover valve in factory gas tank is defective and remains closed. This causes an issue when refilling the vehicle with gas. The gas pump will continuously stop filling as the fumes build up in the tank. This should be a recall as it’s a safety issue and a new tank cost over $2,000.

I am reporting a fuel‑system defect on my 2018 RAM 1500. The vehicle has only 43,325 miles, which is exceptionally low for its age, and it has been properly maintained. Despite this, the fuel‑tank venting system has failed. The dealership diagnosed the issue as a faulty vent valve located within the fuel tank. This defect prevents the vehicle from being refueled at a normal rate. During refueling, the gas pump repeatedly shuts off, and a standard refueling process takes significantly longer than normal. This occurs at all stations and with all pumps. The dealer’s proposed remedy is complete replacement of the fuel tank at a cost of $2,104.64. Because the vent valve is integrated into the tank, they stated it cannot be serviced separately. A critical fueling component should not fail at this mileage under normal use, and the failure of the venting system raises concerns regarding safe refueling, potential fuel backsplash, and proper EVAP emissions operation. This is not a wear‑and‑tear issue. It is a premature failure of a core fuel‑system component. Stellantis has declined goodwill assistance, stating my vehicle is "too old", nor has it issued a recall for this defect, despite the unusually low mileage and the nature of the failure. A quick search on Google or YouTube yields multiple, and similar, customer experiences. I am submitting this report so the federal safety agency can evaluate whether this issue represents a broader defect affecting additional vehicles of this model and generation. Thank you in advance for the federal safety agency's time and consideration.

My vehicle was involved in the Z46 High Pressure Fuel Pump recall. I recently had multiple error codes: P1290, P0087, P1292, P1290. I delivered the truck to the dealer at the end of December and the truck has been grounded for 60 days waiting for the redesigned filter. The ETA for the part keeps changing.
