My brake actuator began making noises and vibrating while still covered by the secondary warranty. I took it into local Toyota dealership, and was told that despite the sound and vibration the car has to throw the proper warning codes to be covered. When my rear window motor overloaded and failed, immediately the vsc/brake/abs warning lights all came on the dashboard. I believe that the brake actuator has been bad for awhile, but only an unrelated electrical surge caused the ecu to trip the brake actuator error codes. I'm grateful that Toyota responded to previous complaints by extending the warranty -but the delay in tripping the error code cost me 6 months of driving with the pulsating and pounding brake noise and allowed my secondary warranty to expire.
