Rattle in dash finally fixed after multiple attempts. There is no recall on it, or service bulliten, but there is an issue with some 2016 Prius with the rattle. While in for the problem I googled it and shared the results with the technician. He removed the part to see if the rattle went away, which it did, and ordered a vent part. Once a new one was installed the problem was solved.
