2008 Lexus RX400 H SE-L CVT 3.3L Electric · RO08 OBR

A pattern of deteriorating front suspension and steering components emerges as the defining mechanical concern across the recorded test history of this 2008 Lexus RX400h, alongside early signs of corrosion that warrant close inspection. The most recent entry on 16 May 2026 recorded a pass alongside a same-day failure that included a Dangerous defect for excessive wear on the offside front lower steering linkage ball joint, classified as presenting a serious risk of detachment, plus Major advisories for a non-functional windscreen washer and an offside front headlamp not operating on dipped beam. Earlier in 2021 a shock absorber on the offside front was flagged with a serious fluid leak, and on that same test an anti-roll bar linkage ball joint dust cover on the nearside front was already severely deteriorated, an advisory that reappeared on the 2019 test for the offside front. The 2025 pass recorded advisories for corroded rear suspension and corroded fuel pipes, which taken alongside the recurring front-end wear items indicates a vehicle whose chassis components are now reaching an age where corrosion and joint degradation are beginning to present in test conditions. The intervening tests in 2020 and 2023 returned clean passes with no recorded defects, suggesting the issues have developed progressively rather than representing an isolated or intermittent fault. Across roughly eighteen years of recorded use the odometer reads 121,036 miles, giving an average annual accumulation of approximately 6,724 miles per year, which sits broadly in line with typical mileage expectations for a vehicle of this vintage. The MOT testing record shows gaps, with no tests recorded between March 2019 and October 2020, and again between October 2021 and December 2023, indicating periods when the vehicle may have been either unregistered, off the public road, or otherwise not presented for testing. From the recorded figures alone mileage progression appears broadly consistent, and there is no evidence of implausibly rapid accumulation that would point to a discrepancy. Given that this is a hybrid powertrain combining a 3.3-litre petrol engine with electric drive components and an automatic gearbox, the relative absence of high-mileage wear on internal drivetrain items cannot be inferred from MOT records, but the chassis and suspension components that are tested have shown progressive deterioration consistent with an ageing vehicle. A prospective buyer should focus inspection efforts on the front suspension and steering assemblies, paying particular attention to the offside front lower ball joint area referenced in the 2026 Dangerous defect, as this is a wear item that can present as a knocking or clonking noise transmitted through the steering when traversing uneven surfaces, looseness in the steering when turned, or visible play when the wheel is rocked by hand with the vehicle raised. The 2021 failure for a fluid-leaking offside front shock absorber should prompt a check for residual damping loss, visible oil misting on the shock body, and uneven ride height, while the recurring anti-roll bar ball joint dust cover advisories warrant a close look at the condition of the anti-roll bar linkages and their bushes for splitting, perished rubber, or play. A road behaviour assessment should include driving over speed cushions and uneven tarmac at low speed to listen for clonks from the front, checking for steering vibration or wander under braking, and confirming that the offside front headlamp now operates correctly on dipped beam. The 2025 advisories for corroded rear suspension components and fuel pipes are particularly significant on an eighteen-year-old vehicle and warrant a thorough underbody inspection, ideally with the vehicle raised, to assess the extent of corrosion on the rear suspension arms, subframe mounting points, and the routing of fuel lines. Corroded fuel pipes present a genuine safety concern and should be examined for surface pitting, perforation, or flaking that could compromise integrity. Brake lines, although not specifically flagged, should also be inspected given the overall age and the corrosion pattern already documented on the rear suspension, as brake pipe corrosion is a common failure point on older vehicles. The nearside front anti-roll bar linkage dust cover deterioration recorded in both 2019 and 2021 suggests the linkage itself may now be worn beyond the original advisory level, and any clonking over bumps or vagueness in the response of the anti-roll bar system should be treated as a likely replacement candidate. The relatively low mileage accumulation and the gap in MOT coverage between 2021 and 2023 also suggest a careful visual inspection of brake discs and pads for corrosion pitting from potential standing time is worthwhile.
