I thought I would give it a few fillups before I did an update on this. I would say that the problem now seems to be corrected.
I took my car to the dealership we bought it from (been going there for 25 - 30 years to buy cars) and I explained the problem and I also brought
in some paperwork I found on-line about this happening to others and also a memo from Toyota stating they were aware of the problem. I also,
after doing much research, explained to them what it seemed was happening, but letting them know they were the Pros in this stuff, not me.
So they took the car in the shop, worked on it about an hour and what they did was to attach a blocking device to the release pin that pulls
back to open the gas filler door. They said (and I read it too in my research) that if the pin gets hit/bumped when the door is open it sends
false info to the cars computer that the tank is full, thus, the gas nozzle keeps clicking off, the gas nozzle has a sensor too.
When putting the gas nozzle in the filler pipe, the nozzle has that big round sealer do-hicky (you know what I mean) at the base, and
that sealer thing at the base of the nozzle hits the gas door lock pin, thus the problem, that blocker protects the gas door pin from
being bumped.
Sorry about not explaining it very clear, I just wokeup (and the sun is in my eyes and there's aliens trying to experiment on me etc etc 🙂 )
The bottom line is, it seems to work, I've filled up like 4 times now making sure that the pin is not touched with no more
click click click when I fill-up.
Let me/us know if this help you.
