Purchased the vehicle new. Brake rotors severely warped AT12,572 miles creating severe vibration/shaking throughout the vehicle when brakes applied. Problem is particularly severe when utilizing breaks on a downhill grade. The severe vibration created a significant safety hazard as it impairs break performance particularly when roads are wet or icy. Car was under warranty. Toyota's solution was to resurface/grind the rotors back to smooth. Unfortunately this process removes metal, and mass, from the brake rotors which exacerbates the problem. Less mass, less ability to dissipate heat. The same problem occurred again at 22,391 miles. Dealership refused to acknowledge the vibration. Returned to dealership at 24,564 miles. Dealership now acknowledged the problem as it was so severe it was impossible to ignore. Once the problem was acknowledged the dealership informed me I would have to pay to have the rotors resurfaced as the car was now out of warranty. Informed them I believe this is a warranty issue as it started during the warranty, but was informed they look at the rotor issues as individual occurrences. Rotors once again turned, further reducing mass and further exacerbating problem. Now a matter of time until issue returns. Brake rotors are clearly made of materials insufficient to handle the weight of the vehicle. This issue also causes severe tire wear, further impairing stopping performance of the vehicle. Toyota refuses to acknowledge tire wear caused by rotor issue.
