Does not lock anymore. The little weak plastic thing is broken. Warranty is gone. Any one know what part number it is to purchase and replace myself? I looked at Infiniti Parts Catalog but couldn't find anything related to gas cap area..

 

as long as it "clicks" when you turn it clockwise it locks. my plastic "thing" broke off too

 

Im sorry i mean the gas cap cover on the exterior of the car so that no one can steal your gas is broken. It doesn't lock when you lock your car.. there is a little plastic thing that locks the cover when you lock your car..
