Miscellaneous -- Verified

The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.

Brakes -- Verified

The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors.  The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).
