My car has the same problem at 70k. You have a leak somewhere.

Mine, luckily is my gas cap. The seal on it is bad.

Try replacing your gas cap and see if that helps.

On another tangent you could see if the dealer will honor it under the emissions items warranty - as that is the purpose of the pressurized gas tank (emissions warranty is a good bit longer than normal warranty 5/75 maybe?)
