Mine warped at 13,400.... $230 to fix.... they told me that brakes are covered up to 12,000 miles..... sucks,,, f'in sucks,,,, looks like $230 a year on brakes.... and that's only the front ones, rotors resurfaced with new pads.... actually,,, i think the vibration started at 11,800 miles,,, but it was mild.... I'm an @ssh0le for not taking it right away..... Procrastination is an evil thing my fellow MSPers.....
