The dealer, IF they received an allocation and ordered your 2022 Elevation, is given a order number. If he cannot give you the accepted order number from GMC, then in all likelihood, they have not ordered the truck because they have not received that allocation. They can tell you it's "ordered" with the dealership but not with GMC. Big difference. I received my order number the day my dealer received an accepted order status from GMC. I could follow along the process by using the chat feature on gmc.com but only with the order number.
I ordered a 2022 AT4 on August 19th, Built on October 14th and delivered to my dealer on November 4th. It has the Duramax but I had ordered mine right before they announced the shortage of parts for the Duramax. My only explanation for my build that was 100% complete, is that it just happened at the right time. I got all my options without any issues including the heated seats, adaptive cruise, wireless Carplay, etc. It was the 288th truck produced in the 2022 LTD model year. I am 35 miles from the Fort Wayne plant and had a couple of friends that are supervisors that followed my build closely once it was in production.
It is a frustrating process, especially in today's environment. It is not going to end anytime soon.
