The failed component is the high-pressure fuel pump, which the dealer confirmed failed and contaminated the fuel system. I do not know whether the failed pump will be available for inspection, since the dealer is replacing it. The engine stalled while I was driving on [road type, e.g., a highway] with my family [in the vehicle / traveling with me] and would not restart, which put us at risk of losing power in traffic. The dealer confirmed the failure and opened the recall repair. To my knowledge, the manufacturer has not inspected the truck. The red throttle warning light came on and the truck stored a P016F fuel pressure code at the time of the failure. A MAP sensor code had appeared earlier and cleared, but I'm not aware of other warning signs before the failure.

Component or System Failed & Availability for Inspection: High-pressure fuel pump and common rail fuel injection system under the federal safety agency Recall 22V‑406 (Recall Z46). The vehicle and all removed/affected components are grounded and available for inspection at Peterson CDJR in Boise, ID under Repair Order #46751. Safety Risk: Risk of sudden loss of motive power and engine stall while driving, creating collision hazards as defined under the federal safety agency Recall 22V‑406. Chronological Timeline & Dealer Findings: July 5, 2024: Peterson CDJR performed Safety Recall Z46 (the federal safety agency 22V‑406) Procedure A, replacing only the high-pressure fuel pump. September 2026 (RO #45520): Vehicle presented with an illuminated check engine light. Peterson CDJR diagnosed a faulty fuel pressure sensor and replaced the fuel rail and sensor for $2,809.45. September 2026 (RO #46751): Following a 55-mile test drive, Peterson CDJR technician verified the diesel fuel from the fuel tank tested completely clean. Inspection of the newly installed fuel rail sensor documented internal metallic debris actively circulating through the fuel system. September–October 2026: Peterson CDJR opened STAR Case #102997574. DealerCONNECT records and the technician notes from RO #45520 state that the entire fuel system requires replacement. Dealer requested authorization for Recall Z46 Procedure B (complete fuel system replacement kit ⁠CSSMZ46DAA⁠). October 5, 2026: Stellantis corporate documented via DealerCONNECT that the fuel system requires replacement, but stated they will not authorize the repair under warranty because the recall was previously closed. Inspections by Manufacturer / Others: Inspected by Peterson CDJR certified technicians and documented in STAR Case #102997574. Reviewed via DealerCONNECT by Stellantis corporate, who confirmed fuel system failure but refused remedy coverage under open Corporate Case #98257662. I have not had followup from my Stellantis case manager.

My 2021 Ram 1500 EcoDiesel previously had the federal high-pressure fuel pump safety recall completed (Recall Z96 / the federal safety agency Campaign 22V767000) on February 12, 2024, where remedy part CSSMZ461-AA was installed. Recently, the vehicle suffered a complete loss of motive power due to a sudden, catastrophic internal failure of this replacement fuel pump. The dealership service department has officially diagnosed the truck and confirmed that the replacement fuel pump blew up internally, sending metal shards throughout the entire fuel system and requiring a complete $9,080 replacement of the fuel loop. This is a complete failure of a federal safety recall remedy, duplicating the exact highway stalling hazard the recall was issued to fix. Stellantis/FCA must investigate why these replacement remedy pumps are continuing to fail and creating dangerous conditions for drivers.

On XXX, approx. 1615 hours, I was traveling EB on I70 in [XXX]. The cruise control was set at approximately 72MPH. I was in the left lane of travel and both my wife and I heard a revving noise and as I looked at the dashboard, I noticed the RPM gauge was high, I hit the brakes and started to go to the right lane and the entire vehicle shut down. All within a matter of 5-10 seconds. The dash indicated to put the truck in park to start it. I was able to make it to the shoulder and get the vehicle stopped and in park. I popped the hood and looked around the engine compartment. I saw no fluids leaking and no steam or smoke coming from the engine. I then attempted to restart the vehicle and it did absolutely nothing. Vehicle was towed to a RAM dealership, [XXX] CRJD in [XXX]. The did a cursory inspection ad determined that the engine was seized up but gave no indication as to the cause. Recommendation was to replace engine at a cost of nearly 18K dollars. Upon conducting further investigation on my own, I discovered that the Z46 recall of the HPFP, described with total accuracy what I experienced on the highway that day. The recall was performed on my vehicle on XXX. It is fully my belief that the fuel pump that was replace through the recall has now failed in the same manner as described in the recall and was the cause of the complete engine failure. I have notified the dealership of my findings and opinions, and they are unwilling to investigate further without direction from the manufacturer. Notified Service Manager, [XXX]. (XXX) 1302 hours On XXX (1310 hours) I notified the RAM Recall Team, [XXX], of the situation. He advised that it was to be escalated to case/claim and that I would be contacted by a case file agent.

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.
