Rx400 H Se Cvt: middle-of-the-pack on first-time pass
Across 538 MOT tests, the Rx400 H Se Cvt returns 76.4% first-time pass — roughly in line with the UK fleet average. The single most-logged Major fail is a torn suspension dust cover. A number-plate lamp out and a split CV-joint boot round out the top three. Average tested mileage sits at 139,196, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.
