Let us know how it turns out.

If you noticed it from day one it is definitely a manufacturing defect, or damage caused while in overseas transit. Knowing Toyota's QC standards, my guess is something etched the glass while in transit. Who knows what could have landed on the glass on the ship or at port.

My only concern would be how the dealer will react since it has been several months and over 1,000 miles later that you are first reporting the defect.
