NHTSA Complaint #11718370 — 2020 RAM 1500

Faulty check valve and EVAP canister/vent While fueling the vehicle, the automatic shut-off closes and will not allow it to fill the tank. This causes fuel to spill out due to backing up in the fill hose. It takes approximately 15-20 minutes to fill the vehicle because the fuel backs up, the pump clicks off prematurely, and it will not allow the fuel to flow consistently to complete fueling. When the gas spills out, it splashes on the person filling the tank, on the outside of the vehicle, and on the ground. This is a dangerous safety issue. The vehicles has not been inspected by a dealer or mechanic yet. There were no warning messages or symptoms. The vehicle has 65,000 miles. The vehicle is available for inspection. I understand that this is a common issue for this vehicle and should be recalled.
