“Driving on dry pavement in mountainous terrain the slip indicator light/sound activates temporarily and the brakes can engage by themselves! Usually happens during right turns. I've been to several automotive specialists for mechanical & electronic diagnosis. I've replaced the lower control arm & the clock spring behind the steering wheel but the issue persists. Online searches indicate this is a common problem with Toyota siennas that is extremely difficult to diagnose & very costly to replace all the possible problematic components! …”
