There is a long list of things to do before the vehicle is ready for sale. https://static.nhtsa.gov/odi/tsbs/2023/MC-10230375-9999.pdf
I wonder if any dealer takes care of the step "Installation of Rubber Body Plugs". Because for sure the regular buyer has no clue about it. And then the car rusts for no apparent reason. I wound if they 4th Gen Prius and the Prime have these plugs too and if they have installed them on my 2021 Prime at delivery....
With our ‘10 the plugs were installed, on one side. Temp spare was 40 psi. 12 volt was dead as a door nail. in that pdf, what was with the 3 kinds of tow eyelets: install one kind, “dispose of” the rest.
