Can you provide a copy of this notice?
The Telluride is not a standard PIO vehicle, as it is produced in the US in Georgia. There is no port transit situation, where options would be installed at port on import from overseas. The usage of the PIO line for options ordering is a semantics issue for the Telluride; as far as I understand, they are factory installed. For any dealer that says otherwise, I would ask where the port is located that installed the floor mats that are listed on the window sticker. Floor mats are a "PIO" option.
The communication was from Kia directly. Certain PIO options such as homelink mirror light kits etc are to be done at the dealer, they are not building them with the cars due to the shortage of parts. From the email it appears as if they install these at the factory after the vehicle is assembled. I can't post internal emails like this, they are for the dealers only
