Sounds like they need to run the list of TSB's with yours too. I imagine you probably need the mandatory list: rear hub nut replacement, passenger door fix, the new side panels at the base of the trunk (they replace the plastic at the bottom of the liftgate area inside the cabin), the DC-DC firmware version, and TPMS pressure setting. They also check your J1772 adapter, your 14-50 UMC adapter. There are also TSB's for things like squeaky brakes (which mine had), rear seat belt alignment, the pano roof creak fix, and a few others.
