TSB for tailgate rusting around hatch garnish and hood scoop?

Hello everyone I am new to the group I have a 2022 4Runner trd pro with 13k miles and my paint is rubbing off around the corners on my rear tailgate garnish and on my hood scoop I took to the dealer and they said there is nothing they can do can someone help me fight Toyota and tell them there is a TSB that this is a known issue on these trucks if anyone can help me find the TSB number and remedy I would greatly appreciate this!

 

Welcome.
With respect to the tailgate garnish, is this thread helpful to you?

It doesn't detail a TSB, that I can remember, but it does offer a DIY solution.

 

Tailgate rust has been a bane of 4Runners since the inception of 4Runners 40+ years ago. Toyota hasn't done anything.

You can remove the tailgate garnish yourself and lay down a strip of paint protection film where the garnish touches the paint. Do this while your vehicle is still relatively new and rust-free, or the fasteners won't cooperate.

 

Thank you for the helpful information
