The 2006 RX450H passes its MOT on the first attempt 82.3% of the time, which is slightly better than the UK average of 80%—but the headline figure masks a serious concern: 40.1% of these cars have recorded a dangerous defect at some point, well above acceptable levels and a genuine red flag for buyers. This high rate of critical faults suggests wear and age are catching up with the model.

At 102,643 miles median, these vehicles are well-used 18-year-olds, yet they're averaging 24.8 advisories per test—a hefty maintenance list that points to niggling electrical and mechanical issues typical of ageing hybrids. Before purchasing, insist on a full service history and independent inspection of the hybrid battery and cooling systems, as repairs on these components are expensive and failures are common in this age bracket.

We have limited data for the 2006 Lexus Rx450h — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
