I PURCHASED A 2019 RAM 2500 TRUCK, AND BEGAN HAVING ISSUE WITH THE TRUCK DROPPING INTO NEUTRAL AT JUST OVER 1000 MILES. I WENT TO THE DEALER AND THEY CHECKED CODES, BUT I DIDN'T MAKE SURE THEY DOCUMENTED IT. IT SEEMED TO ONLY HAPPEN WHEN GOING IN REVERSE AND TURNING, SO I CONTINUED TO DRIVE IT. THEN AT 6670 MILES IT HAPPENED WHILE DRIVING AND IN AN INTERSECTION. I HAD COME TO A STOP AT A LIGHT, THEN WHEN THE LIGHT TURNED GREEN I PROCEEDED TO TURN RIGHT. I GOT ABOUT 10 FEET INTO THE TURN AND THE TRUCK ACTED LIKE IT WENT INTO NEUTRAL. I WAS ABLE TO COAST TO THE SIDE OF THE ROAD AND THE MESSAGE THAT WAS ON THE DASH STATED SHIFT INTO PARK, THEN INTO DESIRED GEAR. I DID AND WAS ABLE TO DRIVE OFF THE ROAD AND INTO A PARKING SPOT OF A NEARBY BUSINESS. I BROUGHT THE TRUCK IN AND THEY OPENED A STAR CASE. EVENTUALLY THEY CHANGED THE TRANSMISSION VALVE BODY AND REPROGRAMMED SEVERAL THINGS. THEY TOLD ME THE PROBLEM WAS SOLVED. AT 9059 MILES IT HAPPENED AGAIN. THIS TIME I WAS BACKING INTO A DRIVEWAY SO I WAS ABLE TO PULL OUT MY PHONE AND TAKE A VIDEO OF THE FLASHING LIGHT OVER THE SHIFTER AND IN THE CLUSTER. THE FIRST INCIDENT HAPPENED ON 1/13/2020 WITH 1520 MILES ON VEHICLE. THE INCIDENT IN THE INTERSECTION HAPPENED ON 5/21/2020 WITH 6670 MILES ON THE ODOMETER. THE LAST INCIDENT HAPPENED ON 7/7/2020 WITH 9059 MILES ON THE ODOMETER.

THIS SAFETY RECALL OCCURRED IN JANUARY 2020 AND I RECEIVED NOTICE FROM DODGE RAM (CHRYSLER). I HAVE CALLED DEALERS IN ST GEORGE AND LAS VEGAS WHO HAVE TOLD ME THE SAME: THEY ONLY GET A FEW PARTS PER WEEK OR TWO TO FIX THE PROBLEM AND PLACED ME ON THE DEALERS "WAITING LIST." I HAVE BEEN ON THE WAITING LIST FOR FOUR MONTHS! THIS IS A SAFETY WARNING REGARDING POSSIBLE FIRE ON MY NEW VEHICLE. FURTHER INQUIRY BY MYSELF HAS REVEALED THE FOLLOWING: 1. CHRYSLER DODGE RAM IS NOT PRODUCING ADEQUATE NUMBERS OF THE SIMPLE PART THEREBY JEOPARDIZING SAFETY OF PURCHASERS AND THEIR FAMILY/FRIENDS. 2. THE FEW PARTS THAT CHRYSLER DODGE DOES PRODUCE GOES TO VEHICLES ON THE LOT SO THAT THEY CAN SELL THESE VEHICLES ASAP. THIS SHOWS NO REGARD FOR THE SAFETY OF PRIOR PURCHASERS. TO THINK THAT CHRYSLER DODGE CANNOT ORDER / PRODUCE THE PART IN MASS QUANTITIES WHEN THEY KNEW THE RECALL WAS COMING IS NONSENSE. BY THE WAY, THIS IS IN REGARDS TO THE W03 2019-2020 SAFETY RECALL. *TR

2EA23001 · High Pressure Fuel Pump Failure
Opened Mar 17, 2023 · No close date supplied
Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
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
PE21021 · High Pressure Fuel Pump Failure
Opened Oct 14, 2021 · Closed Apr 14, 2023
Status: closed (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
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
