2008 Lexus RX400H 3.3L Hybrid electric (clean) · CU08 LDF

The latest MOT test on 11 November 2025 resulted in a pass, but the overall maintenance trend is currently worsening. After several years of clean or minimal reports, the most recent inspection has flagged multiple concerns across the braking system, suspension, and structural areas. The appearance of a minor defect regarding a CV boot, alongside several advisories, suggests that the vehicle is entering a phase of accelerated wear on key chassis components that had previously been stable. With 103,052 miles recorded over 18 years, the vehicle has averaged approximately 5,725 miles per year. This is significantly lower than the national average for a vehicle of this age, indicating light usage or periods of prolonged standing. While low mileage generally reduces engine and drivetrain wear, it often introduces specific risks such as the perishing of rubber components, the degradation of fluids regardless of mileage, and the potential for brake calipers to seize or discs to corrode due to lack of frequent use. Prospective buyers must pay close attention to the front end of the vehicle. The worn front brake discs and deteriorating lower suspension arm bushes are recurring themes, with the latter appearing in 2020 and returning in 2025. During a test drive, listen for clunks or knocks when traversing uneven surfaces or during low-speed manoeuvring, as these indicate failing bushes. The severely deteriorated nearside front inner CV boot is a critical point of failure; if the joint loses lubrication or allows grit to enter, it will produce a distinct clicking sound during tight turns. Immediate replacement of the boot or the entire drive shaft is recommended to avoid a costly failure. The mention of corrosion on the rear subframe mounting area is a point of concern for a vehicle of this vintage. A physical inspection of the inner sills and subframe attachment points is necessary to ensure the corrosion is purely superficial and has not compromised the structural integrity. Given the hybrid nature of the RX400h and its low annual mileage, the health of the high-voltage battery and the 12V auxiliary battery should be verified. Check for any signs of tyre sidewall cracking or perishing, as rubber degrades over time regardless of tread depth, and ensure the service history confirms calendar-based fluid changes rather than just mileage-based intervals.
