Hello all!

I have a 2003 Toyota 4 runner that I bought from my dad (was my dream truck since we got it, Finally got it!! Yay!!) And last year I noticed the rattle whenever the vehicle is on the highway with high winds as well as when the road is rough it kinda makes a rattling noise. Now one day I opened the sunroof on a amazing sunny afternoon and I heard a pop and this plastic piece fell on me on the driver side now it makes kinda a rubbing noise whenever it opens. I hope it didn't break something important but it looks like a rail cover for the tracks. Has anyone tried to take their older 4 runner into Toyota to get this fixed? And im sure they will charge me. Is it that easy of a fix now? I need this fixed!!
