   Prior to paying cash for this vehicle, I had the dealership connect it to an obd-11 scanner to ensure that there weren't any codes. (I wasn't aware at the time that if the codes were cleared prior to the test drive and before the vehicle was drove a certain amount of miles nothing would show up ) The truck seemed to be in ok condition. Before even making it 10 miles off the lot to my home the salesman who was to follow me in my new vehicle had issues and upon return to the…

   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…

    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…
