They haven’t started the steering wheel retrofits yet to the best of my knowledge. I was lucky-ish that I got one produced in June 2022 fresh off if the truck that had everything it was supposed to except for the ventilated cushion chip (the seat back part worked though) and the park assist chips. But speaking with the dealership those other chips including the steering wheel one you are missing isn’t being done yet allegedly. You can keep checking for messages in the OnStar app on the head unit (got the message I could take mine in for the ventilated chip and had it fixed long before I received the letter from GM about it) or keep periodically checking in with your dealership. But otherwise it will continue to be a waiting game.
