I have had repeated problems with this truck, even after repair repairs done by the RAM dealership. Currently, I am experiencing a failure of the high-pressure fuel system. I know it is on recall for other diesel engines, and I believe that this engine should be a part of that recall.

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 2020 Ram 1500 owners say
Most recent owner complaints, unedited.
Recall 01A was performed on my vehicle, but the replacement fuel pump failed again, contaminating the entire fuel loop with metal shavings and risking sudden engine stalling in traffic
Fuel pump failure and fortunately it failed when I had stopped to get fuel.
The contact owns a 2020 Ram 1500. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle stalled with the check engine warning light illuminated. The contact stated that the engine seized. While attempting to start the vehicle, the vehicle failed to start. The contact stated that upon inspecting the vehicle, there were metal shavings inside the engine oil. The vehicle was towed to the residence. The vehicle was later towed to the dealer, where it was diagnosed with a high-pressure fuel pump failure. The contact was informed that metal shavings were found throughout the fuel system. The contact was informed that the fuel system needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle was previously repaired under the federal safety agency Campaign Number: 22V767000 (Fuel System, Gasoline) in January 2025. The contact was informed that the repair was not covered under the recall. The manufacturer was made aware of the failure, and a case was filed. The contact was awarded a goodwill discount of sixty percent off the cost of the repair. The failure mileage was approximately 99,051.
When filling the truck full, fuel will occasionally spill out onto myself and the ground. The fuel also leaks into the cap canister, purge valve and dumps fuel into the manifold as well as leaking on the ground. When driving the entire cab reeks of fuel. This is a known issue by Dodge and they have a TSB out on it. My vehicle could become a fireball at any time. Dealer replaced my evap canister but didn’t even give me the TSB which wound up costing me more money once my mechanic found the problem. This is a 3,000.00 + repair for something that can cause a severe fire.
High Pressure Fuel Pump failed. Pump failure can cause car to stop when not intended. Problem confirmed by an independent service center. Component not inspected by others. No warning lights or messages prior to the failure. The High Pressure Fuel Pump was replaced 4/30/2024 as part on 'Safety Recall Z96 - High Pressure Fuel Pump - Replace High Pressure Fuel Pump' by Merrick Dodge 3614 Sunrise Highway, Wantagh NY 11793.
While coming to a stop at an intersection, vehicle engine stalled and transmission automatically slammed itself into park, with no warning, nearly causing a collision. This issue has previously been recalled for other Ram Trucks - some were not appropriately recalled and pose a major safety risk.
The gas tank does not fill properly and leads to spilled gas while filling the tank. There is a technical bulletin (looks like 14-001-22) that tells mechanics how to fix the issue. I brought my truck to a mechanic who was able to replicate this issue and did confirm with a neighboring Chrysler dealership that they would not help cover the cost of the repair. The mechanic's notes mention that the TSB requires the fuel tank to be replaced entirely. There were no indications that this was an issue prior to it happening ~5 weeks into me owning the vehicle.
Driving and tried to pass a truck loss of power (dash lit up and no top-end) went to limp mode, Hard start upon starting and limp mode continues, code P0336 (crank sensor/reluctor wheel), on dash codes = service electric throttle control & service electronic stability control. Mileage = 110,000, Required service and maintenance completed at recommended intervals, regarding current codes cleaned all related sensors and throttle body, filters and no changes. symptoms are identical to 2019 model complaints. calling dealer regarding fuel system recall and this problem. (this is an estimated $2500 + repair by certified repair mechanic who states repair may fix for a year or less, but it is a continued issue once it starts)
Fueling issue is a known problem, which should be a recall. They even issued a bulletin about it. Fuel Tank Filling Issues (TSB 14-001-22): Affected 2018–2020 Ram 1500s built on or before June 9, 2020 (3.6L V6) or March 16, 2020 (5.7L V8), often due to a faulty rollover valve within the tank. Symptoms include the gas nozzle clicking off repeatedly, making it difficult or impossible to fill the tank
