2006 Lexus RX400H 3.3L Hybrid electric (clean) · LB56 RWU

The 2006 Lexus RX400H presents a stable and largely reassuring maintenance trend, with no serious recurring mechanical failures across its recent history. The most recent MOT, conducted on 12 August 2025 at 47,978 miles, passed, but the tester flagged several minor advisories. These included a slightly damaged or perishing offside rear tyre, a nail in the nearside rear tyre, and a note that a child seat fitted in the rear prevented full inspection of the adult seatbelt. A further advisory highlighted corrosion on a nearside rear lower suspension component mounting point within the prescribed area, though this was assessed as not excessive at the time. The vehicle has not failed an MOT since June 2023, when a simple headlamp aim issue was identified and rectified on the same day, suggesting the owner addressed the defect promptly. The mileage profile is notably low for a vehicle of this age. Between the June 2022 test at 43,160 miles and the August 2025 test at 47,978 miles, the vehicle accumulated just 4,818 miles over a period of three years and two months. This equates to an average of roughly 1,500 miles per year in recent usage, well below the already modest lifetime average of approximately 2,399 miles per year. Such a pattern indicates the vehicle has seen very light use in its later life, which can reduce wear on consumables and drivetrain components but also raises the possibility of prolonged standing periods that can lead to tyre perishing, brake surface corrosion, and dried-out rubber seals. Prospective buyers should pay close attention to the rear suspension and underbody condition during any in-person inspection. The 2025 advisory regarding corrosion on the nearside rear lower suspension mounting point, while not deemed excessive, is a structural observation that warrants monitoring, particularly given the vehicle's age. The rear tyres showed damage and a puncture at the most recent test, and the presence of a child seat obscuring the full seatbelt inspection means the offside rear adult belt should be physically extracted and examined for fraying or retraction issues. The hybrid drivetrain and braking system have not generated any recorded defects, but the low annual mileage means the regenerative braking system and calipers should be checked for sticking or uneven pad wear. Overall, the record reflects a well-maintained vehicle with no alarming trends, though the flagged corrosion and tyre condition justify a thorough underside inspection before purchase.
