Went to refuel my 21017 Prime Advanced and when I started to pump the fuel would no enter the tank. Went directly to dealer. Remedy - There is a recall on the fuel door spring. The defective spring causes the pri to think the fuel door is closed and will not let fuel enter.. The above is as per the service writer.
Sometimes the fuel pump nozzle can hit the door latch too. This can cause the car to close the furl intake because it thinks the door has been closed.
A recall would have resulted in notification to owners and would have shown up on the NHTSA website. It's likely a TSB...but even that would show up on the Toyota Owners website. Posted via the PriusChat mobile app.
I know there was a TSB for some Gen 4 for the same issue. @Elektroingenieur should have more details.
The Gen 4 TSB is T-SB-0220-17 Difficult to Refuel Vehicle Due to Fuel Filler Door Switch Interference Released: May 23, 2017 Comments: The bulletin is applicable to 2016 and 2017 model year Prius cars with VINs earlier than JTDKBRFU#H3038680 (Tsutsumi Line 1) or JTDKBRFU#H3552934 (Tsutsumi Line 2), and also to 2017 model year Prius Prime cars with VINs earlier than JTDKARFP#H3012455, but only if the fuel filler door does not open completely when the fuel door open button is pressed, which can cause the fuel vapor containment valve to close prematurely. The bulletin links to videos showing examples of complete and incomplete door opening.

Toyota’s Lookup Safety Recalls & Service Campaigns by VIN site doesn’t provide information on technical service bulletins, which typically apply only to vehicles that have a specific symptom or condition. In other words, a TSB usually says only how (or how not) to fix a problem after a customer has reported it, while a recall or campaign implies that certain work should be done proactively on all covered vehicles. If you want information about bulletins, you have to ask a dealer, subscribe to techinfo.toyota.com, or wait for them to appear on the NHTSA site or other sources, such as the ChiltonLibrary service (available through many public libraries) or the thread @Prodigyplace kindly linked above.
