2009 Toyota Sienna Electronic Stability Control Esc Service Brakes Problems

While driving on dry pavement at 35-40 mph, your vehicle's traction control system (VSC) suddenly activated on its own—triggering warning lights and sounds, automatically applying your brakes, and pulling your steering to the right. This has happened three times now, and the problem hasn't been identified or fixed despite service attempts. The issue may involve faulty wheel speed sensors, a malfunctioning traction control module, or related brake system components that need diagnosis and replacement.
