fell the same thing about 7 months ago. Took it to the dealer and they replaced the routers. Now im feeling the same when breaking at highway speeds. I dont feel the steering wheel shaking or the brake pedal.

In past Toyota had issues with their brake calipers. Ask the dealer to double check the the brakes again especially on the sliding pins. They tend to get stuck causing vibration when applying the brakes.
