How is the fuel door suppose to stay shut, magnet or spring?

While getting gas yesterday morning i noticed it looked like it was open. when i went to shut it it kind of flopped around and i can manually pull it open with my finger with almost no resistance at all.

 

It stays shut by a locking pin. You need to press in shut, not just close it, the mechanism might be jammed, had it once on my 370Z.

 

HAHA yes, i am aware you need to press it shut, you also need to press to open

what im saying is that once that spring mechanism (that opens it) is compressed the door itself doest have enough pressure to stay again it, it just kind of flops around

 

I've observed that the "leash" or tether that attaches the cap to the quarter panel is often bunched up and obstructive to the fuel door. I usually have to adjust that in order for the door to close flush.

 

Same thing happened to me, adjust tether leash and should shut fine.

 

I had a problem with the fuel door staying shut when I first bought the car. I would refuel, then a week later the gas fuel door wasn't flush with the car. This happened during the winter months and went away on its own.

I told Lexus dealer about it, they couldn't replicate the issue and for some weird reason, it didn't come back during the 2nd winter I had the car. This coming winter will be #3, so I will see if this problem reoccurs.

 

happened to me a total of 3 times. The lid usually pops open when locking your car.

 

Thought it was a defect in the locking mechanism, brought it to the dealer and everything was fine, all the cars in the show room exhibits the same thing. Felt really stupid afterwards.

 

I brought my car in as well and said everything was fine.

The key to make sure it closes properly is the plastic strap has to go forward and underneath the cap when closing. If it bunches up and goes to the left hand side it will not close properly.

 

oh so this problem is not just me! lol

 

Had the same issue. Its most likely the fuel cap cord thing. I took my car in to the dealer the first week I bought the car and it took them an hour to figure it out...

 

fuel cap cord, thanks everyone!
