Fueling difficulty.
I have tried to fill the tank on my '15 convertible three times now. Even tried different gas stations. It keeps shutting off the fuel nozzle way before half tank. No matter how slow I try to put fuel in, it just keeps bubbling up the neck.

Rotate the nozzle so it's up side down

Several of the pumps at the Kroger gas station where I trade do that. I just hold it on the first click of the pump with my finger until I get a stronger disengage from the pump handle.

Just pulling the nozzle out slightly. I've found that I usually have problems if the nozzle is shoved all the way in.

Thanks for the suggestions and input. Unfortunately, I have already (obviously) done all these methods to no avail.

I do not know if they have done something to the nozzles at Costco, but, the last four times I have gone there, I forgot, put it in the normal way I do for our other cars, and I did not have to fool with the nozzle,. I just put it in and it worked.

I have not had that problem with a Corvette but my brother and I have both had it with late model Escalades. Seems that there is a Charcoal Cannister that catches gasoline fumes and has a service life of only 5 years or so. We both run Diablo Tune Tuners and were able to do resets that cured the problem for a few months...then it returned. On my brothers Escalade we discovered that the circuit was shared with the cigarette lighter and the fuse was blowing each time this happened.
In the end...we both replaced the cannister that on the SUVs was in front of the filler neck tube. Not sure if Corvettes use the same system but it's worth looking in to.
Good Luck!!
