Had my first fueling problem

When was this feature implemented?
On my 2013 Prius I don't remember anything like this happening. Maybe I just refueled in ignorant bliss?
I'd hope I would of noticed a MFD message saying Refuel Ready,- but maybe not.

 

I for one am not known for my keen powers of observation. I didn't know there was a change in the game plan, is it that hard to put gas in a car.

Then my local gas station plays games with the stupid gas pump. I have to push about thirty buttons to turn the pump on, the I push the wrong button and it starts all over again and then the car won't take gas.

 

No - we don't have it either. Our button only opens the flap - end of story.

Plus - we put petrol in instead of gas.

 

It appears to be a US or North American Gen 4 thing like the fuel bladder was for Gen 2.
The tank is sealed to avoid the release of vapors. There is a flap in the neck that opens when the fuel door is opened. The flap closes after a timeout or if the door latch pin is depressed. Some people have had the fuel nozzle accidentally depress the latch resulting in the door closing.

When I fuel now I use the vendor’s app on my phone. I just choose the pump number and it is authorized. I choose the fuel type on the pump and fill my car.

 

Probably the same reason US pumps have the gaiter on the fuel pump nozzle that covers the filler neck whilst refuelling to prevent vapours going in to the air.

 

Portable gas cans now have a flap in the spout that closes too. It is a real pain Many people fit an older type spout to the new can.

The new ones like this tend to break & leak, increasing pollution, in my opinion. Notice in the video they are not actually refueling The can is empty.

On my ampera I have to keep the button pressed a few seconds to allow the pressure to balance in/out of the tank

I guess it's the same for gen 4 prius, unlike my gen 3 prius where you just open the cap

 

Sidenote: no, it's way more confusing than that... Only some of our fifty states require that thing on the pump nozzle. States in which the government tends toward less active regulation typically don't require them. They're not installed on pumps in Florida. I used to drive further west along I-10, and pumps in Texas, Louisiana, Mississippi and Alabama didn't have them.

 

That thing can hit the door latch, closing the filler neck too.
