I would imagine it's all shop dependent, but I'll give you my experience with a complete repair of the hood.
Had a 2017 CX5 repainted due to a collision and a year later the clear coat is already coming off and chipping out. So just something to be wary of if you go to a shop.

Mine was replaced with only the windshield. I did have to take it to the dealership at a later date cause the glass replacement company was unable to recalibrate it due to it being so new. All in all, only took a day total.
Has there ever been any true confirmation that the MTS panel switch actually works or is a placebo?? Doesn't pertain to me as I actually have it on my OR. Just curious.
Unfortunately I don't think that's going to matter as this bug is persistent in other Toyota vehicles as well. Just something that they have never addressed - and doesn't seem like they are going to.
