Though I don’t have a concrete answer, I should mention some items that might be of interest:
1. Some GMC dealers are already listing the all-new 2017 Acadia as part of their inventory online. However, I don’t know of any that have physically shipped to dealers yet.
2. Pre-production units have already come off the line for the media drive (link below), so the plant is operational… but not sure if that is taking place for full-production units.
GMA’s first drive of the 2017 Acadia:
