The contact owns a 2023 Ram Promaster 2500. The contact stated that upon approaching the vehicle there was a puddle of fuel underneath the vehicle. The vehicle was taken to an independent mechanic where the vehicle was diagnosed, and the contact was informed that the fuel tank had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 136,000.
My 2023 Ram ProMaster 3500 Van has a fuel leak where the filler-tube goes into the gas tank. I believe others have reported the factory defect & safty hazard. The manufacturer and the dealer will NOT fix it without charging me over $2,500. The vehicle is out of its 3-year, 36,000-mile warranty, but I believe this factory manufacturing defect should be covered. The cost will discourage people from getting it fixed and could lead to major issues later. Jacksonville Chrysler, Jeep Dodge Ram Westside has my vehicle now.
Fuel tank where gasket seal is, leaking gas. Seal cannot be replaced, whole tank needs to be replaced. According to mechanic it will take 3 months to get new gas tank. Looking online and according to mechanic - it it a very common problem with this van. It causes risk of fire while waiting for new gas tank.
We have a 2021 Ram Promaster 1500 Winnebago Pocket Solis. We smelled gasoline while loading up gear for a trip. Upon inspection we saw that gasoline was leaking at the seal of the gas tank. We have taken it to the local Ram dealership that confirmed it is leaking at the cold weld of the gasoline tank. Unfortunately, it is all one piece and the whole tank has to be replaced. $2,400 It is very expensive to replace the whole tank. Our van has only 48k miles on it. It is ridiculous that the tank failed so...

quickly. This is a know facorty defect in the gasoline tanks and it should be warrantied from Ram or recalled with a better design. This failed gasoline tank poses a huge safety concern not only due to fire but also leaking gas vapors into the environment. It should be covered under the Federal Emmisions Waranty. Some states like FL. don't honor that because we don't have emissions programs. We contacted Ram warranty support several times and we were told it was going to be fully covered. When the dealer contacted Ram warranty they deny the liability coverage. We got the run around from Ram. This is so aggravating that Ram is being so negligent about a know significant safety concern and obvious potential fire hazard. This is a bad design of a plastic gasoline tank that eventually will leak at the molded cold weld due to expansion and contraction gas vapors. This whole situation has been a hassle and fight with Ram. We are very disatisfied with the Ram Warranty dept. They basically told us that "sorry you were given wrong information". Not 1x but 2x from agents in the warranty dept. at Ram. So apparently they just lie to owners. Hopefully something is done about this so no one gets hurt or their van catches fire!
What component or system failed or malfunctioned, and is it available for inspection upon request? The plastic fuel tank failed. It cracked/split open and is actively leaking gasoline. The failure is at or near the filler inlet connection where the filler pipe attaches to the tank. The tank is still installed on the vehicle and is available for inspection upon request at Lakeland Chrysler Dodge Jeep Ram (or can be made available wherever the vehicle is located). How was your safety or the safety of others put at...

risk? Gasoline is leaking from the tank onto the ground. This creates a serious fire and explosion hazard, especially near the exhaust system. The vehicle cannot be safely driven and was immediately taken out of service. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The vehicle was inspected and diagnosed by Lakeland Chrysler Dodge Jeep Ram on or about October 6, 2026. They confirmed the fuel tank is cracked and leaking and issued a written estimate for complete fuel tank replacement (parts and labor approximately $2,525 for the tank alone). The replacement tank is currently on backorder with an estimated two-week wait. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected and diagnosed by the Ram dealer (Lakeland Chrysler Dodge Jeep Ram). It has not yet been inspected by the manufacturer, police, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. There were no warning lamps, dashboard messages or check-engine lights. We started smelling gas and it was leaving a puddle when parked. There was enough on the ground to catch fire
Gas tank connection from fill tube to gas tank has a bust on plastic gasket. Leaks gas near the muffler. No replacement part, only option is a new $1,300 gas tank that is back ordered probably due to this issue. I have two vehicles of the same year that are doing the same thing.
Fuel tank leaking gasoline badly, where tank and fuel fill are connected. This is our 6th Pro Master out of the 41 we have so far. This is a very dangerous gasoline leak and, so far we have been lucky with no bodily injury, death or fires
The fuel tank is leaking where the fuel tube goes into the tank. The seal starts to leak and they do not make a replacement seal, you have to replace the entire fuel tank. This is the 2nd Promaster van that I have had and the 2nd time this has happened. This is dangerous to have fuel leaking from the front of the vehicle. This is a poor design, it's a very common problem with these vehicles that still hasn't been addressed. It's also an expensive problem because the tank costs $1300 without labor, and you just can't buy the gasket itself you have to buy the whole tank.

I had NHTSA recall for this generator done (23E-030) which was to solve the same problem I just had. Apparently, they just moved to a smaller diameter fuel line to fit the fuel pump better. However, this hose also came off my Cummins generator fuel pump and was spewing gas all over the generator and the ground when we ran it. This is a very unsafe condition and I'm surprised, after the recall was performed by a certified Cummins dealer (verified by Cummins) that this "new" fuel line has also come off the fuel pump.
