I have a 2008 XLR. After I park I can smell raw fuel. After a day or so I can no longer smell it in the garage. I have an appointment to have it checked so I thought if anyone else has a problem I can let the dealer know.
The dealer found a crack in one of the gas tanks. Since it is still under warrenty it will be fixed with a free loaner. It took for the gas tanks to be full for the dealer to find the problem. New gas tank ordered.
The GM Document ID is 2519705 but the document title is "10150 - Special Coverage Adjustment - Fuel Tank Quick Connector Leak."
It covers 2004 XLRs within the following VIN breakpoints: 45600796 through 45602844.
It also lists all the parts that may need replacement, like the fuel tanks, hoses, gaskets, Aux Fuel Feed and Return pipes. But tank replacement is the most likely fix for this problem.
GM sent letters out in August 2010 warning owners of the potential fuel odor leak and to bring their cars in if they started smelling gas. So it isn't a recall as much as a warning. The problem will be fixed for no charge within ten years of the age of the vehicle or 100k miles, whichever comes first.
Same as above happened to me. Once you fill the tank, it seems to put pressure on the tank and it really smells. Do not park it in a garage. Look under the car and you will see the stain behind the seat on the pan.
