My 450h 2013 with main dealer service up to last 10,000 miles ( mileage 92,000) completely seized up on 12.02.2022. Vehicle recovered to main dealer at my cost . Diagnosis is inverter pump failure leading to total collapse of hybrid system- bill of £000s and no help offered. I feel very bruised. Any similar experiences?
