My 2021 Ram 1500 EcoDiesel previously had the federal high-pressure fuel pump safety recall completed (Recall Z96 / NHTSA 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...

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...

Recently this vehicle has triggered a check engine light. Upon further examination the code was related to an ignition #3. (CODES: P020C, PO1DO).

My 2021 RAM 1500 ecodiesel was subject to an NHTSA recall (23V-263). The recall included a replacement High pressure fuel pump (HPFP) due to a mechanical defect in the Bosch CP4.2 high-pressure fuel pump (HPFP) that causes the pump to fail prematurely and destroy itself internally. The HPFP was replaced under the recall over two years ago, only for the new fuel pump to fail catastrophically and send parts through the fuel loop. The failure has been confirmed by a manufacturer dealership service center (Huntington...

The contact owns a 2021 Ram 1500. The contact stated that the vehicle failed to start and was unable to be jump-started. The vehicle was towed to an independent mechanic to be diagnosed, and it was determined that fuel was not reaching the fuel housing. The contact was informed that the CP4 high-pressure fuel pump was previously replaced under an undisclosed recall in 2024. The vehicle was then towed to the dealer, who had previously completed the recall repair. The contact was informed that the secondary fuel pump...

The vehicle experienced an overheating condition immediately after being picked up from dealership service on April 11, 2026. Within a short distance of driving, a warning appeared and the vehicle became unsafe to operate, requiring it to be pulled over and towed. The dealership later stated that coolant was low but also reported no leaks. This condition should have been identified and corrected while the vehicle was in their custody prior to release. The failure created a safety risk because the vehicle could not be operated safely on the roadway and required immediate removal from traffic. The issue occurred without prior warning before the failure following service.

Wa driving with cruise on at 60 mph. Truck stalled with no notice, no warning lights or check engine light. All temperatures and pressures seemed okay at time of incident. Could not move electronic shifter into neutral, was stuck in drive. Alarm came up to shift to park, I did not shift due to moving at 55mph at this time. Coasted to a stop on side of the road. At about 2-3 mph, truck automatically shifted to park. I attempted to restart truck but engine just cranked over with no fire. Attempted 3 times and still...

The contact owns a 2021 Ram 1500. The contact stated that while driving 55-60 MPH, the vehicle stalled. There were no warning lights illuminated. The vehicle was taken to the local dealer, who replaced the high-pressure fuel pump under NHTSA Campaign Number: 22V767000 (Fuel System, Gasoline, Engine); with the additional repairs on the low-pressure fuel pump at the Owner's expense. The vehicle was partially repaired. The manufacturer was contacted and opened an investigation. The failure mileage was approximately 102,000.

I was suddenly unable to fill the fuel tank of my truck on the way back from a 4 hour road trip in freezing conditions. I was able to get just enough fuel into my vehicle to make it back due to it occurring during a fuel up on the last hour of the drive. However, if this had happened earlier in the drive, I could have been stranded with my family in freezing conditions. There were no warnings and it hadn't been happening prior, other than a half dozen times randomly over the past 2 years where the fuel station...

Change in acceleration since purchasing truck. Discovered recently the fuel pump was causing the problem. Also the air bag light comes on and warning of a safety issue.

I was driving on the highway going the speed limit and the car suddenly slowed to 35 and all sorts of lights (check engine light and others) came on and messages went across the screen about the throttle control and stability control. This is the 4th time this has happened to me. Each time I bring it to the dealer and am told "its a known computer glitch" or that there is a fix but it continues to happen again. Suddenly losing power and speed has caused other drivers to slam on breaks, swerve, etc. In order to reset the car I have to pull over on the highway to restart it. This is putting my safety and the safety of others at risk.

My vehicle is currently at the service department of a dealership by my, Covert CDJR Bee Cave, due to two codes that recently set: P0EA7 and P026E. Mopar/Stellantis issues a TSB for this issue. Number 07-003-22. This is a known and documented issued but if your vehicle is outside the original 36 month, 36k mile warranty they will not cover it. This issue is not from wear and tear it is a defect and flaw in the original design. I have requested good will coverage and up to this point have been denied.

Failed fuel pump Needs a new fuel pump at 34000 miles. Vehicle currently at the dealership service department I saw there were previous recalls on these vehicles and their fuel pumps I should not have to replace a fuel pump at this mileage, ever

Driving to work and my truck lost all electrical power. All display lights turned on and hazard light signal started blinking but the hazard lights were not actually on. I then lost all electrical power; power steering, hazard lights would not turn on, all dash lights and display lights, head lights at first and then the battery died a couple minutes after that started. I could not put the truck into neutral so I could push it to the shoulder of the highway. I had to put it in Neutral manually with the pull tab...

After having the Fuel Pump replaced, it was revealed that there are wires above the fuel tank that have melted and are causing a fuel leak into different elements of the under carriage of the truck. The manufacturer is not willing to honor the recall and replace these parts (even though they are connected to the fuel system) so by their own logic this must be considered a separate issue. It is concerning that there is electrical melting occurring and causing a fuel leak right next to the effected area

Recall Statement - Fuel Overflow and Injury Incident Involving 2021 Dodge Ram 1500 I am reporting a recurring and hazardous issue with the fuel system on my 2021 Dodge Ram 1500. March 30, 2025: While refueling at a local gas station, the tank overflowed by approximately 3 gallons once it reached full capacity. I initially believed the problem was due to a faulty pump and notified a station attendant to clean the spill.

Recall NHTSA 22V-767 pertained to a potential faulty high pressure fuel pump. The recall notice states: "FCA US will repair your vehicle [2] free of charge (parts and labor). To do this, your dealer will replace the HPFP, inspect and, if necessary, replace additional fuel system component." When I took the vehicle in for repair, the dealer replaced the fuel pump and also told me that there was a problem with the fuel pressure sensor that could cause the vehicle to stall at highway speeds. The said that only the...

Gas filler line (exterior of car to gas tank) exhibits blowback when filling gas tank resulting in backup of gasoline /fuel often spilling on to pavement and clothing/shoes. This is a personal safety and environmental impact item. Multiple instances reported in on line forums and verbally acknowledged as a frequent problem in RAM 1500 vehicles. No lights/warnings were noted. Problem started at greater than 65000 miles. Problem is not intermittent.

When attempting to refuel the vehicle with gasoline, the refueling nozzle automatically stops after just 1 or 2 seconds of fueling at the full flow rate. Even at somewhat slower rates, something happens to cause the refueling nozzle to shut off ("click off") the fuel flow. Operating the refueling nozzle at a very slow rate is the only way to get fuel into the vehicle. This takes a very long time. Pulling the nozzle partially out of the filler neck can help increase the flow rate, but then gasoline unexpectedly...

Big oil leak on 3.0 Eco-Diesel front lower timing chain cover Dealer been trying to repair leak for over 2 years. Keepes leaking more and more. Yesterday driving smoke and oil fumes were coming inside the vehicle. You could smell burning oil. This vehicle is a major fire hazard and unsafe to drive. It's also hazardous to the environment and salmon streams. I see from the internet lots of other owners are having this same problem

I was driving on the highway when my vehicle suddenly lost power and simultaneously the service throttle control and service electronic stability control messages came up as well as the check engine light came on. This also happened last November and the dealer said they fixed the issue (high pressure fuel pump) but it has now happened again. I was concerned for my safety as well as my passengers and others as we did not have adequate power to get up a hill. And the sudden slowing nearly caused an accident.
