The sulfur content in the fuel is contaminating the contacts of the sending unit.

Some people have had good luck with some fuel system cleaners solving this problem. The cheap stuff doesn't seem to do the job.

Not that GM isn't completely exonerated from fault but the gas stations don't do a very good job of watching what the stations sell.

Replace the cap - it's only about 10 bucks at AutoZone. They told me the same thing about taking time to clear. I disconnected my battery for 10 minutes and it went off. Make sure you have the radio code as it will need to be reset after disconnecting the battery. It should have come with the car but the dealer can provide it.

P0183 = Fuel temperature sensor A circuit, high input

P0455 = evaporative emission (EVAP) control system leak detected (no purge flow or large leak)

P0463 = fuel level sensor circuit, high input.

Check to see if the charcoal (evap) canister is full of fuel. If so, empty it. Check for a faulty canister vent valve. Check for a short to ground in wiring to fuel temp sensor and fuel level sensor.
