I'm on my 3rd one from Honda, and it is very difficult to tighten the cap, and loosen the cap.

On top of that, every now and then I'll get a Check Engine Light, and its usually always the fuel cap completely off!

 

Never had a problem with my S or the Civic Si I had before it.

 

I believe there was a problem with the filler necks being out of round. I remember reading on the site of people bringing in their cars to have them replaced. I just apply pressure while screwing it on, it seems to work. Before that I'd hear three clicks and think it was on only to find that it had backed off ( smelling gas fumes while driving).

 

There is a Service Bulletin for deformed fuel filler pipe, I've seen it on 2 other cars, as well as mine.

 

I had to get a new aftermarket gas cap about 2 years ago when the car was just over a year old. I elected to get a locking gas cap (double protection) and have not had a problem since.

 

I'm on my third one. They last about a year for me.
