2018 Ram 1500 Fuel System Problems

I am reporting a fuel‑system defect on my 2018 RAM 1500. The vehicle has only 43,325 miles, which is exceptionally low for its age, and it has been properly maintained. Despite this, the fuel‑tank venting system has failed. The dealership diagnosed the issue as a faulty vent valve located within the fuel tank. This defect prevents the vehicle from being refueled at a normal rate. During refueling, the gas pump repeatedly shuts off, and a standard refueling process takes significantly longer than normal. This occurs at all stations and with all pumps. The dealer’s proposed remedy is complete replacement of the fuel tank at a cost of $2,104.64. Because the vent valve is integrated into the tank, they stated it cannot be serviced separately. A critical fueling component should not fail at this mileage under normal use, and the failure of the venting system raises concerns regarding safe refueling, potential fuel backsplash, and proper EVAP emissions operation. This is not a wear‑and‑tear issue. It is a premature failure of a core fuel‑system component. Stellantis has declined goodwill assistance, stating my vehicle is "too old", nor has it issued a recall for this defect, despite the unusually low mileage and the nature of the failure. A quick search on Google or YouTube yields multiple, and similar, customer experiences. I am submitting this report so NHTSA can evaluate whether this issue represents a broader defect affecting additional vehicles of this model and generation. Thank you in advance for NHTSA's time and consideration.

I wanna report a refuling issue with my vehicle. I have an issue with the gas pump clicking or turning off numerous times it started happening not to long after having the truck. I have to literally hold the pump with my hand to refuel my it. If I don't do this the tank will never get filled. I also have to watch closely so the gas doesn't overflow and pour out on my truck to the ground. This has happened in the past very dangerous and wasteful with gas coming out like that. I have read different fixes for the problem but no help from Dodge about it as apparently no recalls about this issue. Which it looks like I'm going to have to try and get it fixed out of my own pocket. It's a struggle everytime time to fuel it up. I think Dodge should fix this especially since it's already known about by them.

When fueling the vehicle it routinely clicks off and fuel is splashing out at times. When I bought the truck in 2018 the dealer said this is a known ram issue and would be a recall soon. The problem has never been fixed and is getting worse where there is fuel and vapors escaping the filler routinely. If you Google this on reddit forums or Ram forums it's a common problem. It also causes people to fuel their trucks improperly to get around the issue causing even more safety issues.

My vehicle was involved in the Z46 High Pressure Fuel Pump recall. I recently had multiple error codes: P1290, P0087, P1292, P1290. I delivered the truck to the dealer at the end of December and the truck has been grounded for 60 days waiting for the redesigned filter. The ETA for the part keeps changing.

The vehicle had a recall of a high-pressure fuel pump. I was driving on the freeway when the vehicle suddenly stopped. I had the vehicle towed to the closes dealership. I was told that at the time the manufacture did not have the parts to replace the fuel pump and the debris passed through the system damaging filter and the catalytic converter. I was told by the dealership mechanic that there were metal shavings through-out the system. They partially repaired it and once I went to register my vehicle at the DMV they wanted proof of the recall repair. I took the vehicle back but the dealership does not wish to repair the consequential damage the recall caused. I still do not have my vehicle or proof the vehicle is in a safe working condition. Dealership and Manufacture refuse to repair the vehicle.

Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was 95,544.

1 of 2 Gas tank mounting straps released, rusted thru the frame and the gas tank was hanging by the rear strap only. could have been a huge fire risk if tank released and ruptured on the road.. has not been reported thru dealer yet, had same issue on my 2011 ram 1500 which was recalled to fix. only warning was seeing something hanging under my truck and hearing a new noise as the metal strap rubbed on the drive shaft.. i crawled underneath and found as described above.

The front fuel tank strap fell off and tank is now hanging. When looking at strap, I noticed the frame mount that holds strap was corroded/rusted and had snapped, causing strap to let go. This was a recall back in 2009-2012 on this same vehicle. This should be looked at ASAP and recalled. This is a safety issue. Thankfully I found this before tank dropped out while driving.

The gas tank will not take fuel. Tried multiple pumps at multiple gas stations and the pump keeps turning off. You have to keep restarting the pump over and over again. If you look it up online, there are hundreds of people having the same issue and most cases seem to be a faulty rollover valve, the filler neck itself or a complete replacement of the gas tank. If someone isn’t monitoring the fuel level with the ignition on and they keep restarting the pump, they may over fill the tank and pump gas on the vehicle or themselves which is hazardous and could be potentially fatal.

The vehicle started rattling currently its not starting i almost crashed a car in front of me, the truck is in jordan am not in the usa and the dodge local dealership refused to do the recalls stating that there is no support for diesel rams they even refused to provide the parts or the software… If this truck is not supported world wide why did they allowed its exportation kindly help me with this

High pressure fuel pump failure while driving. This vehicle shows potential recall for this part but for some reason my vehicle is not listed in the system for this recall. I have a 2018 ecodiesel with the 3.0

Subject: Request for Warranty Coverage Review – Fuel Tank Filling Issue / TSB 14-005-25 I am writing this too you to requesting assistance regarding a persistent issue with my 2018 RAM 1500 SLT (VIN: [XXX] ), which is having difficulty when refueling. The fuel nozzle consistently shuts off prematurely, and in many cases, will not activate the automatic shut-off mechanism. I often have to stand at the pump and manually control the nozzle to refuel the vehicle. As a result, the tank sometimes overfills, spilling gasoline down the side of the truck and onto the ground — posing a serious safety and environmental hazard, including the risk of fire. My mechanic informed me that this issue is covered under Technical Service Bulletin (TSB) 14-005-25, dated February 20, 2025, which states that certain RAM 1500 models—including mine—may have a manufacturing defect requiring fuel tank replacement. According to the TSB, this issue affects vehicles with the 5.7L V8 HEMI engine and either a 26 or 32-gallon fuel tank, built on or before March 16, 2020. My vehicle matches these criteria exactly. However, when I took the vehicle to my local Dodge dealership, they informed me that the repair would not be covered under warranty, without providing a clear explanation. Given that this issue is acknowledged by RAM as a manufacturing defect and involves a potential safety hazard, I am seeking clarification and assistance in resolving the issue as suggested by the TSB guidance for known issue. Any help that you can give me would be greatly appreciated. Thank you for your time and assistance. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We purchased the RAM in September 2024. 5 times since our purchase, while filling the gas tank the pump nozzle has gotten stuck and extremely hard to remove from the gas tank. This last incident was on 2/9/25, prompting us to take the truck into Dodge where it is currently waiting to be looked at. This is a serious issue that needs to be addressed and corrected as vehicles are very expensive to have these types of defects. It took 3 grown men to remove the nozzle from the tank.
