Hose came off and power steering fluid leaked everywhere. Made it extremly hard to steer.
lost of major fluid and complete lost of sterring
Driving, stopped at light, when accelerated and turning it sounded light a reviving engine (really lound) and than we could barely turn the wheel - fluid all over under hood - we immediately took home and parked - will have to tow to repair
