2007 Lexus RX400H 3.3L Other · FD07 UEP

The most recent MOT inspection on 21 August 2026 resulted in a pass, but the record indicates a concerning trend of recurring suspension and drivetrain issues. While the vehicle has successfully passed its last few tests, the frequency and nature of the advisories suggest a progressive degradation of mechanical components rather than a stable maintenance regime. Specifically, the recent appearance of a minor defect regarding a severely deteriorated nearside front inner drive shaft constant velocity boot, alongside multiple advisories for worn suspension arm pins and bushes, indicates that the vehicle is entering a phase of increased maintenance requirements. The transition from simple brake and tyre advisories to more complex drivetrain and suspension component issues suggests that the cumulative wear is beginning to affect the vehicle's structural and mechanical integrity. With a recorded mileage of 240,938 miles over approximately 19 years, this Lexus RX400H has covered an average of roughly 12,681 miles per year. While this is considered moderate to high for a luxury hybrid of this age, the high total mileage places significant stress on the hybrid battery system, electric motors, and the complex all-wheel-drive drivetrain. High-mileage vehicles of this era often face accelerated wear on rubber components such as bushings, seals, and boots, which is clearly reflected in the current MOT history. The consistent usage pattern suggests the vehicle has not been sitting idle for long periods, which is positive for battery health, but the sheer volume of mileage means that major components like the hybrid inverter, suspension geometry, and transmission are likely nearing the end of their service life. During a test drive, you must pay close attention to the handling and auditory feedback from the front end. The advisory regarding the nearside front inner drive shaft constant velocity boot is a priority; a weeping joint can lead to grease loss and eventual catastrophic failure of the drive shaft, often manifesting as a rhythmic clicking sound during low-speed turns. Furthermore, the repeated advisories for worn suspension arm pins and bushes on both the nearside and offside fronts, as well as the sub-frame, suggest the vehicle may exhibit clunking noises over bumps or a vague, wandering sensation through the steering wheel. You should also monitor for uneven tyre wear, as the recent advisory regarding the nearside front tyre wearing on the outer edge is a classic symptom of incorrect camber or toe settings resulting from the aforementioned worn suspension components. Finally, the history of pitted and scored brake discs, combined with thinning pads and previous shock absorber leaks, necessitates a thorough inspection of the braking system and chassis. Check for any brake shudder or pulsation under deceleration, which would indicate warped or heavily corroded discs. Given the advisory for general underside corrosion noted in 2023, you should inspect the vehicle's structural integrity from beneath, looking for significant scale or perforation on the sub-frames and exhaust system. Because this is a high-mileage hybrid, ensure that the cooling systems for both the internal combustion engine and the hybrid inverter have been regularly serviced, as fluid degradation can lead to overheating in these complex, high-use systems.
