We just purchased a 2022 Silverado 2500HD High Country. I built it online and received an allocation for the build in April. When we picked it up, we realized the park assist button didn't work and the sales guy told me we didn't have that option. Nor did we have the Automatic Emergency breaking. Said it didn't come with our package. Yes it did, I made sure of it, I got the High Country Deluxe package, it came with everything. We paid for upgrade rims and tires and the dark essential package and were told that GM would send it all separately. He then waited and told me it was all backordered. He should've told me that before. The crash alert works some times but not all the time, but it never does the auto braking and the park assist doesn't work at all. When in reverse the alert for an oncoming car works. Our heated / cooled seats and steering wheel works. Why would some of it work sometimes but not all the time? And why wouldn't the park assist feature be listed in the settings on the screen?
