Sounds like you have some poor dealers not staying on top of orders. You'll see GM accepting orders, then making changes all the time when it goes to production. Case in point, every single Yukon Ultimate is being submitted with Super Cruise as it's a standard option for that trim. Every single one will be changed by GM at time of production because they don't have the hardware for Super Cruise.
Very dumb IMO and honestly I'll probably be getting an ESV with Super Cruise as soon as they're available, trading in a new '23 Ultimate to do so. The dealer can see all these changes as they take place in Global Connect, they just aren't taking the time to follow up.
