RS5 Rotors

Please forgive me? I’ve come across a thread on Audizine that that has several people complaining about warped rotors
on RS5s within about 12,000 miles. My dealer even advised me of a recently sold RS5 they had in their shop that had the problem and they blamed it on "spacers’? Good grief!!! Opinions please.
