There are 2 owner-reported fuel system complaints for the 2018 Audi RS3in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I attempted to add gas to a 3/4 full fuel tank (given that I had a long drive that day and needed a full tank). Fuel would not enter the tank, no matter how slow I seemed to pump the gas. I had filled up a few days prior and driven the car about 100 miles since. After calling the dealer and taking the car in for service the next day, the dealer noted that the car needed a new fuel tank because components in the fuel system had failed. The service advisor stated that there was a recall on a different model, but same platform of Audi, but that recall did not apply to my car. I have since read that there is an investigation on fuel issues on my model by the NHTSA. I have also seen recall information about VW and Audi vehicles and models similar to my car. This appears to be a major and frequent safety issue. If not quickly remedied, fuel can leak and/or evaporate out of the tank or into the charcoal canister and fill an area with gas fumes. In addition, not being able to add fuel to a car is a major problem which can leave a driver stranded or incapable of using their vehicle. There were no warning lights or fault codes.
The suction pump located in the fuel tank failed, causing fuel to back up into the evaporation canister and out of the vent tube in the rear passenger wheel well, which is a potential fire hazard. This is the exact same part a recall was issued for in NHTSA campaign numbers 16V647 VW and 16V647 Audi
