I just bought a 2017 Santa Fe Sport AWD. When I tried to fill it the gas kept shutting off. I decided to put it on the slowest fill notch (very frustrating). When it shut off again I restarted filling and put 4 more gallons in. Any ideas how to fix this?
Probably evap charcoal canister and/or vent valve clogged or stuck
Air must flow out for gasoline to flow into tank
If vent valve or charcoal canister clogged or stuck closed then will cause issue with re-filling gas tank
Your car is new enough that it should be covered by warranty??
To clarify what Camper said, and this applies to all modern vehicles. Most of the time you know roughly how much fuel the vehicle needs based upon the fuel gauge reading. When the tank is full and the nozzle clicks off, you may add fuel one more time. The second time it clicks off STOP. Trying to "fully top off" the tank as some folks do can lead to fuel going places that it should not, such as the charcoal canister and repairs for that may not be covered by any vehicle warranty.
