Hey guys, I am approaching the end of my 36k 'bumper to bumper' warranty, and we all like free work haha

Any suggestions as to what I should check out before taking it in?

I already checked my doors and yes, the paint is rubbed off in spots under the door

My list so far-
new passenger door speaker, blown
new weather stripping all around, have had some leakage issues, nothing major
paint under the doors

Any suggestions of stuff to check will help, thanks in advance!
