NHTSA complaint #11753305 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
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 Beach, CA). The failure lead to immediate engine shutoff while driving in traffic. The vehicle could not be moved out of a busy street under its own power. There were no warning signs prior to failure.

FUEL SYSTEM, DIESEL
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 located in the engine compartment needed to be replaced; however, the repair would be an out-of-pocket expense. The vehicle was not repaired due to the cost. The manufacturer was not contacted. The failure mileage was approximately 85,000.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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 nothing. Waited 20-30 min and attempted again and same result. Call for tow truck and had towed to dealership. While waiting for tow truck, had full power in truck, no warning lights. Checked fuses for fuel and found no issues. Did hear fuel pump engage when turned ignition to run. Checked oil level, oil was changed 800 miles prior to incident, oil was at full level on dip stick.

NHTSA complaint #11713579 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
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 nozzle clicked off a few times prematurely. But never to the extent of not being able to fill the tank. It was brought to a dealership and is currently having the fuel tank replaced due to a bad valve inside of it.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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 under the steering wheel. My Ram 1500 5.7L hemi etorque was towed to Andy Mohr Chrysler Jeep Ram. The service shop told me that the motor generator unit is on back order and it could take a month or 2 months for the part to come in.

FUEL/PROPULSION SYSTEM
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

FUEL/PROPULSION SYSTEM
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. May 2, 2025: At a different gas station, while refueling the same vehicle, a small amount of fuel again overflowed unexpectedly. This raised concerns, as it occurred under different fueling conditions. May 25, 2025: While refueling at the same station used on May 2nd, approximately 5 gallons of gasoline overflowed from the tank. As I attempted to remove the nozzle, I slipped on the spilled fuel and fell onto the concrete, injuring my right leg. At this point, it became clear that the issue was not isolated to specific gas station pumps, but rather a defect in the vehicle’s fuel system. This ongoing issue poses a significant safety risk. Beyond the environmental hazard, I could have sustained a serious head injury or worse during the fall. I am convinced there is a malfunction in the fuel system of my vehicle, and I strongly believe this warrants immediate investigation and a potential recall. This matter is unacceptable and must be addressed to prevent further harm to myself or others.

On 3/6/25 at 0520 hours, I 95 northbound in Stafford, VA. at mile marker 141 in left travel lane at approximately 75 mph the truck suddenly lost power slowing significantly. We pulled over onto the left shoulder as the truck slowed and stopped. The truck required shutting off the ignition and restarting the vehicle for it to operable. We had vehicles behind us slamming on brakes and quickly changing lanes in order to avoid hitting us. This truck has been checked by a dodge dealership for previous complaints of this occurring at lower speeds. Dodge dealership told us, there are no codes, no recalls ( only on V8) , we can note it in file but there is nothing else we can do. This is unacceptable and almost got us into a serious accident. There is something wrong with the etorque.

FUEL/PROPULSION SYSTEM
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 fuel pump was covered by the recall, yet the recall notice also clearly states "additional fuel system components." Should the dealer be covering the fuel pressure sensor also given that it is a fuel system component that could cause the vehicle to stall at highway speeds?

FUEL/PROPULSION SYSTEM
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.
NHTSA complaint #11627301 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
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 splashes/spills out of the filler neck and can splash on the person refueling as well as down the side of the vehicle and onto the ground. This situation is a fire hazard and an environmental hazard.

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.

I have tried at three dealerships to get this recall repaired over the last two years. Everyone tells me they cannot get the parts including a replacement fuel pump. Each dealer has stated that it needs to be replaced. I drive this vehicle everyday at apparently my own risk. The state of Ohio sent a letter requiring repair of this safety recall. Any assistance in this matter would be greatly appreciated. With an open safety recall I am unable to trade or sell the vehicle.

FUEL/PROPULSION SYSTEM
We purchased a new 2021 Dodge Ram in November of 2021 from Desert 215 Superstore in Las Vegas, NV. Nine months later the truck stalled while driving. The dealership kept the truck while they repaired the fuel pump. They had our truck for seven months while they attempted to repair it. The dealership couldn't figure out how to repair the underlying cause of the faulty fuel pump--therefore they replaced the powertrain, transmission, and engine. Approximately, one year later on [XXX], 2024, the truck stalled while crossing a busy intersection--my husband had our two young sons in the car which could have resulted in a serious accident but thankfully did not. We received a recall notice again last night about the fuel pump along with two other notices. Therefore it was not repaired correctly the first time. I looked up the vehicle information online and there are several class action lawsuits due to the aforementioned as this imposes a serious safety and hazardous risk to our family along with other drivers that can potentially result in injury or death. The entire vehicle needs to be recalled for a manufacturer defect under the premise of product liability. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We purchased this Ram Rebel on 03/26/ 2022 from El Cajon Ford. At the time, we checked and there were no recalls associated with it so we went ahead with the purchase. However, in Oct 2022, we were notified of a recall associated with the truck's fuel system. We promptly contacted the dealership who said the recall parts were on back order. Every few months for the next year we called to inquire about the status of the parts concerned for our safety in the vehicle. Each time we called, we were told there was nothing they could do because the parts were back ordered. On November 11, 2023 we were driving home from a friend's house and the truck stalled in the middle of a busy road (Scripps Poway Parkway) jeopardizing our safety and causing emotional distress. We were able to get the truck to the side of the road and wait for a tow truck. The truck was towed to Carl Berger Dodge/Jeep/Ram dealership (which is the one we use for our routine maintenance) where it sat for 9 days before they even looked at it. At the time, it was determined to be caused by the fuel system recall by Ram. After weeks of conflicting information, we finally were able to contact Ram Customer care and get a case manager who authorized 1 week of a truck rental. After that we were only authorized $40/day for a rental which gave us a small car. We have a travel trailer and boat we tow with the truck and also are still making payments on the truck and trailer ($1200/month). So far, we have had to cancel 5+ trips and have spent over $4000 in payments for a truck and trailer we are unable to use because of this recall. Ram has not given a time frame for the backordered part we need to fix it and our truck has been out of service for 106 at the time of this writing. This has caused us financial and emotional distress and we would like to file a complaint. We would like for Ram to buy the truck back so we can purchase a different vehicle and be done with this nightmare.

FUEL/PROPULSION SYSTEM
Around 12/4/2023 I took my 2021 Ram ecodiesel in for a recall on the high pressure fuel pump (z96 recall). It was the first time this dealership had done one of these recalls. After 2 days of working on it , I got it back. 2 weeks later, 12/20/23 I auto started my truck with the factory auto starter. Once I got into the truck, and attempted to turn it on, it set off alarms, asked for anti theft code, and the dash lights were all on saying I had all sorts of issues. I called RAM and was told I needed to tow it to the nearest dealership, which I did on the same day 12/20/23. After almost a month at the dealership and no information, I drove my wife's car and went to talk to them. They told me they believe it is a bad fuse box and need to replace the entire fuse box (TIPM). My concern with talking to other mechanics is that they feel the recall work was not all done correctly and that the relay or some wiring was not put back correctly. Now I have been out a vehicle for over a month as I write this, my recall work has caused more issues that I will have to pay for. This needs to be fixed at the expense of RAM and need assurance that no other electrical issues will occur because of this recall work

FUEL/PROPULSION SYSTEM
My RAM truck stalled about 2 months ago. When towed it to the dealer they diagnosed a high pressure fuel pump failure which was due to an open recall. I had attempted to take care of the recall multiple times but I was told that the part was not available yet. Now that it caused a bigger issue with the truck, it has been over 2 months and the truck is just sitting on the dealer. It has been impossible to get a rental car while the truck is waiting for repair. This should not happen. The truck is 2 years old. It was obviously due to a faulty factory part. If I could get a loaner vehicle for the duration of the repair this situation would be more tolerable. Instead, countless phone calls and emails and still no loaner vehicle. I will never buy Chrysler again in my life and will discourage as many of my colleagues to do the same. It's embarrassing how Chrysler does not care about its customers. I'm also still making payments for a truck that continues to be at a dealer for over two months now without a near end in sight.
