FUEL/PROPULSION SYSTEM
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
NHTSA complaint #11763389 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
On XXX at approximately 1:00 PM, while driving my 2022 Ram 1500 3.0L EcoDiesel on [XXX] east of [XXX]/north of [XXX], a rigid metal diesel fuel supply tube fractured at approximately 49,209 miles. The failure caused a substantial uncontrolled release of diesel fuel into the engine compartment and underneath the vehicle. Diesel fuel traveled underneath the truck and contaminated portions of the rear of the vehicle. The vehicle's check engine light came on, became disabled and required repair away from home. The failed component has been retained. Photographs show a visible crack/fracture in the metal tube itself rather than at a threaded connection. A replacement Mopar tube was obtained from a Ram dealer. The vehicle previously underwent the Ram/Stellantis high-pressure fuel pump (HPFP) safety recall, Recall 01A/NHTSA 23V-263, on XXX. I do not currently know whether the failed tube was replaced or disturbed during that repair and have requested the prior repair records. I am reporting this because a sudden pressurized diesel fuel leak into the engine compartment presents a potential fire hazard. I have retained the failed component and can make it available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
It appears to be a fuel leak. The incident happened less than 200 miles after having a dealer perform the NHTSA recall 22V-406, FCA recall Z46. The truck caught fire while pulling a travel trailer. The only way we were aware of it was a passing motorist saw flames shooting out from under the right side. As soon as we pulled over the truck immediately filled with smoke and the fire spread as the fuel puddled below the truck. Chrysler sent an inspector to look at the truck, not enough of the engine, passenger cabin, or front of the truck was left to make a conclusive cause. There was no indication we had an issue and if not for the fortunate timing of the passing motorist this could have turned out much worse. I was relating this story in a restaurant to my nephew when a passing waiter asked if it was a ECO diesel and I said yes, he related his story which was identical including the recall. I attempted to put out the fire with a fire extinguisher we kept in the truck but it was too big by the time we pulled over. We were traveling at less than 50MPH stop and go traffic which had just started moving.

FUEL SYSTEM, DIESEL
The contact owns a 2022 Ram 1500. The contact stated that while driving approximately 40 MPH, the vehicle lost power and coasted to a stop along the curb, stalled, and the transmission independently shifted to park(P). The vehicle failed to restart, and the Police arrived on the scene to assist with traffic control. The vehicle was towed to the local dealer, who replaced the high-pressure fuel pump as part of the repair under NHTSA Campaign Number: 23V263000 (FUEL SYSTEM, DIESEL). However, the repair failed to fix the vehicle. The vehicle was towed to a second dealer, and it was determined that during the failure with the high-pressure fuel pump, the valves in the engine were damaged. The contact was informed that the engine needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 139,000.

FUEL/PROPULSION SYSTEM
This vehicle was subject to NHTSA Recall 22V-767 / Stellantis Recall Z96 for a defective Bosch CP4.2 high-pressure fuel pump (HPFP) known to fail and release metal debris into the fuel system. The recall remedy (HPFP replacement) was performed at an authorized Stellantis/Ram dealership on 3/29/2024. On 8/9/2026, while driving the vehicle suddenly lost engine power and blocked the road in the left lane. The vehicle failed to restart and needed to be towed. The vehicle was independently inspected at Saddleback Automotive Service Center, Santa Ana, CA (RO# 130026). The technician documented diagnostic trouble codes P0087 (fuel pressure governor deviation, low pressure), P025C (fuel pump module control circuit low), and P016F (closed-loop fuel pressure control at limit, pressure too low) — all consistent with the same CP4.2 HPFP failure mode the recall was intended to remedy. Photographic and video documentation confirms metallic contamination in the engine oil and fuel filter screen. This failure occurred more than two years after the recall repair, and Stellantis (Case #97888077) has denied consequential-damage coverage citing the standard 24-month Mopar parts warranty on the replaced pump. I am filing this complaint because the recall remedy performed in March 2024 appears to have been inadequate: the vehicle experienced a recurrence of the same fault codes associated with the recalled component, and the resulting metal contamination caused catastrophic engine damage. I believe this indicates the recall remedy did not fully address the underlying defect and that other vehicles that received the same recall remedy may be at risk of the same outcome. I am requesting that NHTSA investigate whether the 22V-767/Z96 recall remedy is adequately preventing this failure mode in vehicles that received the HPFP replacement, and that this complaint be associated with any existing investigation into recurring CP4.2-related failures post-remedy.

FUEL/PROPULSION SYSTEM
My vehicle has experienced a serious and extremely dangerous loss-of-propulsion condition on three separate occasions. The first time this happened, my RAM only had 4,513 miles on the odometer. I addressed this issue with my Carl Burger Dodge advisor in writing when I dropped it off and asked him to call me about it, but he never did. He also did not add anything I mentioned on my departure paperwork. He completely ignored this liability. While driving normally in DRIVE, the truck unexpectedly shifts out of gear and effectively goes into NEUTRAL without any input from me. The “P”/Park indicator flashes, the vehicle will no longer respond to accelerator input, and I lose the ability to accelerate. To recover the vehicle, I have had to bring it to a complete stop, shift into PARK, and then shift back into DRIVE before propulsion is restored. This is not a normal transmission shift or a minor drivability concern. The vehicle is unexpectedly losing the ability to accelerate while in motion. This creates a serious safety risk, particularly in traffic, while merging, crossing intersections, or traveling at highway speeds. The condition has occurred three separate times, and I have video documentation of one of the incidents. I have also identified other reported complaints involving 2025 Ram 1500 vehicles experiencing similar unexpected loss of propulsion, neutral/gear-selection problems, flashing gear indicators, and the need to stop the vehicle and reselect PARK and DRIVE. I am therefore formally placing Ram/Stellantis on notice that I consider this a substantial safety defect and am requesting that the manufacturer repurchase the vehicle rather than simply continuing an open-ended repair process.

FUEL SYSTEM, DIESEL
The contact owns a 2015 Ram 1500. The contact stated that the dealer performed an unknown software update associated with an unknown class-action lawsuit settlement without the owner's consent. Following the software update, the vehicle experienced cooling system failures, including oil intrusion in the coolant reservoir and brown and burnt coolant. The vehicle was taken to the dealer on several occasions and was eventually diagnosed with a turbocharger oil leak. The turbocharger was replaced under warranty; however, the failure persisted. The vehicle was taken back to the dealer several times, and the diesel particulate filter (DPF) was replaced. Additionally, while driving 68 MPH, the vehicle stalled, and the low oil pressure warning light illuminated. The contact pulled over to the side of the road. The vehicle was towed to the dealer, where the engine oil and oil filter were replaced; however, the failure worsened, and the engine made an abnormal knocking sound. The vehicle was taken back to the dealer, and was diagnosed with a blown head gasket, and the engine was replaced; however, the failure persisted, resulting in additional failures, including emissions failures. The vehicle was towed to an independent diesel mechanic, where no diagnostic trouble codes were found. The contact stated that the new engine failed at 100,000 miles. The vehicle was not repaired. The manufacturer was notified of the failures, but no assistance was provided. The failure mileage was approximately 30,000.

FUEL/PROPULSION SYSTEM
While accelerating the vehicle stalled and came to a complete stop. I was unable to leave the road way due to the vehicle stoping, shifting to park, setting the e brake. I then had to push start again and pull to the shoulder. The vehicle then indicated a battery warning light, and the voltage indicated the battery was below 12v. Upon returning home and restarting the vehicle all warning lights turned off and the battery voltage indicated no issues. This vehicle is on its 3rd 12v battery. It has gone to the dealer multiple times over the battery. It hesitates while accelerating but without expensive diagnostics I had no recourse.

FUEL/PROPULSION SYSTEM
I am writing to request your assistance regarding my 2016 Ram 1500 EcoDiesel and the handling of a safety-related recall repair that has not resolved the original issue. My vehicle has been experiencing the following symptoms: •Check engine light •Hard starting •Engine struggling to start •Engine stalling These symptoms prompted me to bring the vehicle to an authorized Ram dealership for diagnosis and repair. The dealership informed me that the vehicle qualified for Recall Z46, and the recall was subsequently performed. Unfortunately, after the recall was listed as completed, the vehicle continues to exhibit the exact same symptoms that existed prior to the repair. The check engine light remains, the vehicle still struggles to start, and it continues to stall. After further research I discovered that the entire recall was not completed based on the procedures listed on the NHTSA website. This is extremely concerning because these symptoms create a potential safety risk, particularly when the engine stalls unexpectedly. I have attempted to work through Ram Customer Care to resolve this matter. My experience has been disappointing. I have been unable to obtain meaningful assistance or authorization to have the vehicle evaluated by another certified Ram dealership despite my concerns that the original dealership did not successfully resolve the issue. At this point, I have lost confidence in the original servicing dealership's ability to properly diagnose and repair my vehicle. I have maintained detailed records of my repair visits and communications and am prepared to provide copies of repair orders and any additional documentation needed. My goal is simply to have my vehicle repaired correctly and safely.
