Gas Door Latch Won't Stay Closed

[mysmith4]

I filled up my 2005 XLR with gas last night and the check engine light came on this AM which prompted me to open the gas door. Now the gas door won't close. I think the latch is broken. A quick fix was to put clear masking tape over it but I refuse to ride in an XLR with tape on it! Is this an easy fix or will I need to have it serviced by Cadillac? I haven't had the car for a full month yet and this will be the third visit to Cadillac dealership - air bag light; svc tire monitor message; window stripping/bracket repair on right side window.

Is it broken or has the latch stuck in the open position? If you open the trunk there is a manual release cord, try manipulating that. Maybe a shot of lubricant on the latch will do the trick? The latch is a shaft inside a tube and maybe it needs a tiny bit of light-weight lube, hopefully.

Don't use a silicon based lube near gas, silicone is death to O2 sensors.

Mine did this and would eventually comes back out (plunger that latches the door) after driving.

In any case it is a solenoid tat needs replacing. Mine was replace 6 months ago under GMPP warranty.

It is a nuisance, but got worse over time.
