I don't think this is a parts issue if the 12/13s are getting built/shipped before anyone in our group is. If anything, this is probably a more intense QC/audit of the builds for our week. Just a guess though.
My window sticker was last updated on 12/14. My blend was 12/6 but I haven’t heard anything from my dealer since I spoke to him last Tuesday about it shipping.
Someone with a twitter should ping them and see what's going on with the 12/6 build week broncos as nobody as built or shipped emails. 12/13 group already getting both shipped and built emails before we even get either.
