Howdy Prime Family! We've had our prius for about 2 years now. Recently, when we press the gas tank button, the gas tank lid doesn't want to open. Does anyone else have an issue like this yet? Ive tried cleaning the knob and for some reason after not fueling for a week or two the button won't open the gas tank. This morning I pressed it 5-6 times and it finally opened after about 3 min lol. I tried pressing the button again and it worked. It's so random.
Depends on how many miles on the car. Probably just a simple need for some oil as @john1701a already mentioned. Had the same issue a while back with my wife's '07. Edit to add: if you press the button and the door doesn't open, it may have opened just enough that you can pull it the rest of the way open with your fingernails. If it didn't move at all, then it'll take two people.
Yeah, I'm just thinking, OP mentioned "about 2 years" ownership, and with basic warranty being 3 years or 36K miles, get dealership on it, verify it's not a failing/sticking cable somewhere in there.
Is it possible the Evap system has to go through a 'pressure equalization' routine before releasing the door? It was noted here that the Prime has a positive pressure fuel tank evap system, like other PHEV's, to help keep the fuel fresher and moisture out. Possibly your system is slow to equalize for some reason....? (just a wag....)
