Repairing rotors

My rotors need to be repaired on my car that is 2 1/2 years old. The brake pads are only 60% worn and have never been replaced. Is this common or are the rotors defective?

Rotors don’t get “repaired”, they get replaced. “Repair” would mean “turned” on a lathe, but nobody does that anymore. It leaves the turned rotors more susceptable to warping.

Why do you need them replaced? Is the car pulsating when braking?

Repaired probably means replaced probably because they are warped. On major cause of warped rotors is improper lug nut tightening and not a fault of the rotor. More info = better answers.
