Gas cap loose at different times
My cap seems to do the same thing. I have had it in to the dealer three times for CEL. Each time they replace parts. Now they want to replace the tank and 2 O rings. I keep telling them about the gas cap thing that I have read about here, but they keep ignoring it.

So a simple test would be to top off the tank? I suppose it would still take a few starts to clear. Can the appropriate cap be purchased rather than counting on a hapless dealer to find it? I don't want these local clowns near my car.

It will not clear until it is done so with a scan tool or disconnecting the battery. Been there done that.
Mine cleared on the drive home from work after taking the cap off and screwing it back on. I cleared it with the cortex once too. Haven't tried the battery disconnect option.
When I renew my plates I may just go with "FU P0442". That would be a great inside joke plate.
Current tank of fuel is almost empty and it hasn't appeared at all during this tankful. I've only had it 3 times in 6 months of ownership, so either the cap is bad or I cross-threaded it three times(which is pretty likely too).
