I used to be very picky and tried to fix every single rattle, squeak on my vehicles by going thru dealership and ended up costing me more problems/issues from the incompetency of the dealers and learned my lesson to not bother anymore if it is not serious issue (i.e. mechanical) but that's me...

As an FYI, I have the already known famous rattle/criquet noise but does not let it bother me...
