Rear brake rotors on a 2023 Lexus RX350 are warping at 20,000 miles with hot spots, causing brake pulsation, and dealer quoted $550 for resurfacing which is seen as unreasonable.
No affordable, convenient alternative to dealer service for diagnosing and fixing brake rotor warping; car owner lacks knowledge on whether this is a common defect or a design issue.
