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 onl

My 2021 Ram ProMaster experienced transmission failure and became inoperable. It is subject to Safety Recall 44A/NHTSA 23V-301 involving the 62TE transmission.

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.
