2006 Lexus RX400 H SE-L CVT 3.3L Hybrid electric · LB56 RWF

The 2006 Lexus RX400h SE-L CVT presents a stable but watchful maintenance trend following its most recent MOT pass on 9 January 2026 at 110,400 miles. While the vehicle has consistently passed its annual tests, the record reveals a pattern of minor advisories that have persisted across multiple cycles rather than resolving, suggesting the previous owner accepted cosmetic and borderline wear items rather than proactively rectifying them. The January 2026 test flagged corrosion on the integral body structure, though the tester judged structural rigidity not significantly reduced. A windscreen defect noted as not adversely affecting the driver's view has appeared in every test since at least January 2024, indicating a long-standing chip or crack that has gone unrepaired for over two years. The offside rear tyre was again worn close to legal limits in both January 2025 and January 2026, pointing to a recurring alignment or suspension geometry issue on that corner that has not been addressed. The mileage profile tells an interesting story. Across roughly twenty years this vehicle has covered approximately 110,400 miles, averaging around 5,520 miles per year, which is notably low for a vehicle of this age. The annual increments tell a more nuanced picture. Between 22 January 2024 at 105,108 miles and 10 January 2025 at 107,268 miles, the vehicle covered 2,160 miles. The following year to 9 January 2026 at 110,400 miles saw a larger jump of 3,132 miles. Looking further back, the vehicle accumulated 7,900 miles between 24 January 2022 and 2 February 2023, then only 3,685 miles in the subsequent eleven months to January 2024. This irregular pattern suggests periods of very light use interspersed with occasional bursts of regular driving, which can be harder on consumable components than consistent mileage would be. Seals, rubber bushes, and brake components can deteriorate from standing rather than use, something low annual mileage does not prevent. A prospective buyer should pay close attention to the structural corrosion advisory from the January 2026 test. While the tester deemed it not significantly reducing rigidity at the time of inspection, underbody and subframe corrosion on a twenty-year-old vehicle warrants a thorough physical inspection, particularly around suspension mounting points, sills, and the rear subframe area common to this generation Lexus. The recurring offside rear tyre wear pattern demands a full four-wheel alignment check and inspection of the rear suspension bushes, toe arms, and shock absorbers for wear or deterioration. The persistent windscreen damage should be assessed against current MOT standards, as a crack or chip that was borderline in 2024 may now exceed the acceptable limits in the driver's primary field of view. The braking system also merits closer scrutiny. Rear brake discs were flagged as worn, pitted, or scored in both February 2023 and January 2022, and while the January 2025 and 2026 tests did not repeat this advisory, the earlier history suggests the rear braking circuit has been a known weak point. A test drive should evaluate whether the rear calipers are binding or if the handbrake mechanism, common on the rear axle of this model, is causing uneven disc wear. The slight steering rack free play noted in January 2022 at 85,683 miles did not reappear in subsequent tests, but a physical inspection of the rack boots and track rod ends remains prudent given the vehicle's age and the potential for long-term standing to degrade rubber components.
