The contact owns a 2020 Ram 3500. The contact stated that while driving at various speeds, the vehicle made an abnormal ticking sound. The vehicle was taken to the dealer, where it was diagnosed with high-pressure fuel pump failure, but the vehicle was not repaired at the time. The contact stated that upon pulling into a parking lot, the vehicle stalled. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the high-pressure fuel pump had imploded, causing damage to the fuel system. The dealer related the failure to NHTSA Campaign Number: 21V880000 (Fuel System, Diesel), and the vehicle was repaired; however, the contact later became aware that the dealer had replaced the high-pressure fuel pump with the same part. The contact stated that upon taking the vehicle to an independent mechanic to be serviced, the mechanic informed the contact that the high-pressure fuel pump installed on the vehicle was not the recall part, but the same defective part. The mechanic recorded the high-pressure fuel pump and part number, and the vehicle was taken back to the dealer, where it was confirmed that the recall part had not been installed on the vehicle. The manufacturer was notified of the failure and referred the contact to the dealer for assistance. The contact stated that the dealer delayed performing the recall repair free of charge, which required the contact to pay for the replacement of the high-pressure fuel pump with the correct part. The vehicle was repaired. The contact stated that the manufacturer failed to complete the recall repair free of charge. The failure mileage was approximately 38,000.

Codes: P2002, P242F, P2463, P1451 Failures: DPF, Charge air cooler leak, PM sensors, EGR internally cracked, Catalytic Convertor, Pink tinged oil, strong diesel odor in oil - post failures. Erratic def gauge readings, unstable idling, clunking downshift when exhaust brake decelerates, warm up stumbling. Power reduced, see dealer (over and over and over and over). Limp Mode (5 MPH). Permanent ticks/taps from front left motor, front passenger wheel well, passenger side mid-truck. Extremely loose gear shifter plus an occasional “Vehicle Not in Part” message on the dash display. Manufacturers Service Center (local and ONLY Ram dealership) has reproduced the issue. Independent Diesel Mechanic shop also reproduced. Service center and Independent shop both inspected. The safety issues of a 5 MPH limp mode and risk of sudden engine stalls while driving in traffic, especially on an interstate should be fairly self explanatory… As is a constant “Power Reduced See Dealer” problem, when your truck is used to do what it’s designed to do… Tow large loads. As is an extremely loose gear shifter that doesn’t always properly register as “in Park”. The date listed below is simply the date of the very first occurrence. It’s not a representation of every date after. The most recent date was just last week.

While driving Down a paved roadway on 6/30/23 @ 5pm doing approximately 20 miles per hour the vehicle died and the dash lite up with every single message possible such as 4WD inactive, oil change due, fuel filter service required and etc. Attempted to restart the vehicle for about 25 minutes when another citizen noticed we were having issues with the vehicle so they stopped to assist us. The citizen towed my vehicle to location we were staying at for the weekend and upon arrival to the location I disconnected both battery terminals to allow the computer modules to drain/reset. After allowing the batteries to be disconnected for several hours I hooked them back up and tried starting the vehicle and was unsuccessful getting it to restart. I disconnected the batteries again for the night and returned the next morning to hook them up. after hooking the batteries back up, I was able to get the vehicle started and moved it around at the place we were staying at and allowed it remain running for about 20 minutes before I shut it off. Went and did other projects and about 5 hours later returned to the pickup to see to see if it would start since we were heading back the next morning and it started so I figured it would get us home on Sunday July 2nd. On July 2nd @ 11:30am started the pickup to leave and everything seemed normal. We drove about 5miles from the location we were staying at and were approaching an intersecting highway OR58. I proceeded out onto OR58 westbound and as we got about 1 mile down the road when the pickup died and every message was being displayed again. As we sat way off the shoulder of OR58 incident response pulled up behind us to make sure everything was ok. I told the incident responder that we were good and I was working on contacting RAM for a tow. About 15 minutes had passed and IR person walked away then the pickup started. I was able to drive the pickup about 2 more miles down the road when it died again and had to be towed.

My check engine light went on, along with the DEF warning, early June 13th,2023. The DEF warning stated I had 150 miles to get the Track to a Dealer. After Dealer evaluation, I was told the truck had DEF contamination, from ,Diesel Fuel. I asked how this could happen? I was not given an explanation. To me this is a DEF Pump failure. The DEF Pump did not have enough PSI to inject DEF into the Diesel Fuel, so the Diesel Fuel back flowed into the DEF system. Additional facts, my Truck warranty expired 5/15/2023. My truck has less than 36,000 miles. I had the High Pressure Fuel pump, Recalled fixed in May 2023. I was told this repair did not lead to this issue. The Repair bill is over $3700 for this repair.

My high pressure fuel pump went out while I was towing the 43 ft enclosed trailer causing the engine to shut down. I was able to get it home and onto a car hauling trailer took it to a dealership and confirmed the high pressure fuel pump was the culprit they informed me that they would not perform the safety recall because of a modification to the vehicle which has no bearing on the safety issues at hand I contacted FCA they encouraged me to take it to a different dealership which I did. I had to pay a tow truck to haul it to another dealership in which they told me they would do the recall however when they put my VIN number in their system my pickup had been blacklisted by the parent company Chrysler saying do not work on this vehicle for safety recalls. I at this point got quotes to have it done and it was extremely expensive to friend advised me to look into the law so I contacted a lawyer and they told me to file a complaint with NHTSA.

Y78 Recall. The recall for the CP4 pump has been issued. Ive been on the dealership waitlist since the recall became available.My truck began to have rough idling and surging which it never had before. I called the dealer to ask a timeframe for when the recall would be completed, they advised me that they were no longer receiving pumps for the recall and had not received any in a few months. The lady in service advised me if I was that concerned for pump failure to try and source a pump conversion kit myself and submit for reimbursement afterwards (which I did). I submitted copies of receipts from both the retailer I ordered from as well as credit card statements showing proof of purchase which FCA required per their email. However, FCA has denied my request for reimbursement of parts. I have been in communication with them via email trying to get a explanation of why I was denied. They stated that I do not meet criteria for reimbursement even though I have submitted all required documents that they ask for. They are unable to provide explanation aside from their automated generic response saying I do not meet criteria. I have tried calling their provided customer care number to speak to a representative but have been unable to talk to anyone other than an automated system.

0N 4/4/2022 while traveling on interstate 64 E in WV ,towing an R V camper , no warning signals on the dash screen, my truck started losing power and went completely dead,just missed by a tractor trailer rear ending me, as I rolled off to the side of the road. Iwas towed to the nearest Dodge dealership. When I arrived at the dealership a mechanic came and open the hood, he found diesel leaking and a metal rod of the camshaft sitting on top of the engine, which he stated shot through the engine block. Warranty company doesn't want to tear down engine after I gave approval to investigate issue. This is my work truck and source of income. Four weeks later, I am not getting help from dealership that sold me the truck and warranty. Warranty company is trying to use loop hole to get out of paying. I found similar complaints, reported to the NHTSA, engines falling apart while driving down the road. I had to pay for my truck to tow from WV to Charlotte NC to my driveway. I have a case# with the Dodge Customer Care Department and they are just informing me that the truck has recalls, but parts are not avaible at this time.
