ADAS keeps faulting and disabling the cruise control, pre-collision braking, hill hold assist, and skid control functions. The event occurs at highway speeds with strong crosswinds that rock the vehicle in a busy side-to-side motion as gusts hit the vehicle. The system seems to reset after turning the engine off & restarting. But the loss of some of the safety features is worrisome in traffic.
