Just got back from the petrol station but had a little bit of a nightmare filling it up. I pressed the fuel button to pop the lid open but nothing happened. Cut a long story short I spent about 5 minutes fiddling with it until it finally popped and I was able to fill up.
Does anyone else have this issue? What can cause it and is there anything i can do to stop it happening again?
It seems to work completely fine now after I freed it, but now I'm worried that I'll be in the middle of nowhere the next time it sticks shut!

Re: Fuel cap wont pop open
Not really an answer, but I had this happen on my bike and also saw a Japanese YouTuber describing the same issue on his PCX, so it seems to be a common problem. I asked my shop to look at it and they seemed familiar with the issue and fixed it quickly. I suspect it's something as simple as tightening the bolt on the hinge or similar, but I neglected to ask.

Put any card "ATM size" on it. Try it and thank me later

Re: Fuel cap wont pop open
That does sound like an absolute nightmare. And sorted with an excruciating 5 mins of fiddling. Awful.
What options are open to you so that this absolute disaster doesn't happen again?

I had the exact same issue on mine about a week ago. I was able to get it to pop open, but I haven't looked further into it.

Anyone know what the dealer fix is? I've had it happen a number of times now and it's pretty annoying.

Re: Fuel cap wont pop open
I don't know how similar the new ones are to my 2013, but when that was sticking, a dab of silicone grease on the catch helped. The biggest impact was by poking the release switch HARD, not just pressing it lightly.
Re: Fuel cap wont pop open
I took my PCX in for the first service a few weeks ago and mentioned the problem. The mechanic said that they file a bit of the plastic down on the catch and it fixes it, very common problem apparently.
