I just spoke to an SA at my service center who categorically said that no one has access to this information, and any information that they give you is false, and should not be considered accurate. She was very clear, NO ONE outside of the factory can see where a RN is in the build process, until a VIN is assigned.
I give up. This business is run like a start up, and has one of the worst customer-facing purchase experiences I have ever seen.
And before you say "it's the entire industry", believe me, I know it and live it every day. We deal in ICs and electric components on the scale of hundreds of thousands of orders, and we try to do our best to tell people the status of their purchases. This is truly unacceptable.
