Hi, just bought a new 2022 Venice GTS and after 260 miles I got the check engine light on. The car ran smooth and no issues while in idle, but I took to the dealership anyway. It took them several days to get back to me, saying that they ran the scanner and found that the error code for the gas cap sensor, they contacted Vanderhall who told them to clear the code and ride for 60 miles and see if the check engine light would come back on again.

I went to pick up the car, they had put 10 miles on it already. I brought it back home, drove a few times, and around 70 miles after clearing the code the check engine light got back on again. I called the dealership and they want me to take the vehicle back for another tests (what ever that means).

 I bought a OBD reader and scanned the codes, see the attachment. I'm looking for guidance since the dealership is kind far from me.

EDIT: attachment did got through. Here are the codes:
P0442 EVA System Leak Detected
P0650 MIL Control circuit/Open

650 code tells you malfunction indicator light is lit
Evap, code is inter related to gas cap. But not really.Told by very reliable source, that the purge solenoid valve notorious for going bad in all ecotec engines. It can be tested, its near the dipstick on a 2022 v v  it polls the fuel tank pressure few times. One is on fill up. Leading you to believe its bad cap.
Really its a leaking solenoid.  At first was small leak then larger evap leak.  Working on that, will report with the cure! Im obsessed!

what gas cap did you buy? can you share more information? I would like to try it just to rule this possibility out.

I prefer the factory cap, it needs fixed if you shake it and it sounds like a loose BB in there.We have taken ours apart and hot glued it back into the knurled cap
