Rx 450h F Sport Cvt: a strong MOT record by UK norms
Across 683 MOT tests, the Rx 450h F Sport Cvt returns 87.8% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a torn suspension dust cover. Windscreen damage and a missing suspension dust cover round out the top three. Average tested mileage sits at 90,054, which is the lens to read those failure rankings through.
