2019 RAM 5500

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, NHTSA 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 NHTSA 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.nhtsa.dot.gov/owners/SearchNHTSAID 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

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021 to investigate allegations of 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.On November 12, 2021, FCA filed vehicle recall 21V-880 and equipment recall 21E-094 on the subject population, identifying an `internally failed component? of the high pressure fuel pump equipped on the 6.7L Cummins Turbodiesel engine that introduced debris into the fuel system potentially causing fuel starvation and consequently an unexpected loss of motive power. Discussions with FCA identified the high pressure fuel pump equipped on these vehicles as the Bosch-supplied CP4. On December 16, 2021, Bosch filed recall 21E-101, stating the pump failure was a consequence of a manufacturer application-specific fuel system design.NHTSA subsequently identified recall 21V-586 involving loss of motive power due to failed CP4 fuel pumps on certain BMW vehicles.As a result of having received multiple recalls related to a common component, from two separate vehicle manufacturers, NHTSA?s focus shifted to determine if the related defect allegation was limited in scope to the recalled population. In early 2022, information request letters were sent to FCA and BMW to determine the root cause and consequentially identify the proper scope of potentially defective vehicles. After ODI received their information request response, FCA filed recalls 22V-406, 22E-048, 22V-767, and 22E-087. During review of information request response materials, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA or BMW. On March 17, 2023, this Preliminary Evaluation was upgraded to an Engineering Analysis (EA23-001), expanding the scope to include the Tier-one supplier and any manufacturer who equipped or installed similar high pressure fuel pumps subject to the failures observed in the recall population.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 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, 11448163, 11458918, 11460558

The DEF system failed on this truck at the end of 2025. The truck has entered limp mode, and if we continue to drive it, it will shut down completely. The vehicle has been at Darling's RAM in Ellsworth, ME since March 2026, and they say that they are still waiting for the parts. Why aren't parts available?? They have no idea when parts will be shipped from the manufacturer. Why is this at all acceptable?? I am running a business, and I am having to cancel orders from my customers because Stellantis is not sending the parts. This makes the vehicle unsafe to drive, and I feel that this is unacceptable.

While unloading cargo, I was standing on the flatbed of the truck, leaning over the standing side-gates, without realizing they weren’t locked in place. The gates fell down onto a co-worker and I fell out of the truck. Similar incidents have occurred before and after this accident. These gate latches don’t have any warning systems in place to indicate when they are unlocked. It is unknown if this component has been inspected by others.

I would like to report a major safety concern with the push button start system and programming on the 2019 and up 5500 cab and chassis with the 6.7 Cummins. On November 29th we had a 2019 Ram 5500 that went in the ditch and ended up on its side because of soft ground. It was laid fully on the passenger side. It was still running. Operator tried to turn off engine and it would not. After he climbed out drivers side window he tried to clamp off fuel line. Truck continued to idle until it stuck a few of the main bearings to the crank shaft . truck was towed in and all fluids were checked and filled as needed. Turning the engine over with a barring tool was I was able to free it up. I charged batteries and turned on key it wouldn’t crank. (shifter was in park when unit was unloaded off wrecker into shop) PCM has numerous codes including lost communication with TCM. Didn’t display gear selecting in cluster. After clearing codes truck would start and run. These chassis’ will not turn off if the transmission dash display does not display park or neutral and will not turn off if PCM loses communication with TCM even if transmission is in park or neutral.. Luckily this was not an accident were anything started on fire but chassis should either have a impact or tilt sensor or programmed so if you hold start button for a certain amount of time or press it a certain number of times it overrides ignition system. A mechanic with a 2019 2500 with the Cummins says that his manual states that it button is pushed and held it will turn ignition off after holding for 5 seconds. I test a couple of other 2019 5500”s that are located here and with transmission in drive, vehicle stopped motor running have held button for up to 3 minutes and pushed it up to 30 times and ignition will not turn off unless dash display shows park on neutral. If there had been damage to fuel lines it could have been pumping diesel fuel onto the accident scene

The transfer case shifted itself into neutral while driving on the highway. It wouldn't go into any other gears and it lost all functionality. I wasn't under load and had been maintaining a set 65 mph. There was no warning the RPMs just redlined. I set the vehicle into what registered as park and when I got out it continued to roll towards me. I had 3 small children in the vehicle at the time and had we not made it off the highway in time I hate to think what could have happened. I am a mechanic by trade and it is the only reason we were able to get it to a safe area.
