2009 Lexus RX400H 3.3L Hybrid electric (clean) · RO09 NVR

The most recent MOT test on the 2009 Lexus RX400H was conducted on 2026-06-05 and resulted in a pass, though it carried two advisories: an offside rear outer sill holed, which indicates localized structural damage likely from impact or prolonged exposure to moisture, and slight play in the offside rear antiroll bar D mount, suggesting wear in the suspension linkage or mounting points. Despite this, the overall maintenance trend over the past year is stable rather than worsening, as the vehicle passed in June 2025 and June 2026 without major failures, though the recurring issues from previous years—particularly the front suspension arm ball joint wear and drive shaft joint boot failures—remain unresolved. The presence of these persistent defects, however, signals that the vehicle has undergone significant mechanical stress over its lifetime, warranting careful attention to their progression. The recorded mileage of 109,702 miles for a 17-year-old RX400H represents a moderate annual usage rate of approximately 6,453 miles per year, which is broadly consistent with typical operational patterns for this age group. Such mileage accumulation is unlikely to be indicative of excessive driving, but it does imply that consumables like brake pads, tyres, and fluids have been subjected to regular wear. The absence of particularly high mileage spikes suggests that the vehicle has not been driven at an extreme pace, but the extended period between MOT tests (up to two years) could indicate periods of prolonged inactivity, which may have contributed to minor corrosion or fluid degradation. The most critical implication here is the need to monitor for standing-related issues, such as brake disc corrosion or caliper binding, which can develop when components remain stationary for prolonged periods. Given the recurring major defects—particularly the excessively worn front suspension arm ball joint and the compromised drive shaft joint boot—buyers should prioritise a thorough inspection of the front suspension assembly. Visually check for any signs of oil leakage around the ball joint, which may indicate further wear or failure, and listen for unusual clunking noises when the vehicle is driven over bumps or uneven surfaces, as this could signal loose or failing suspension components. The exposed tyre from the 2023 MOT failure underscores the importance of verifying tyre condition, including sidewall integrity and tread depth, as exposed cords or ply can lead to sudden blowouts. Additionally, the exhaust major leak and structural sill corrosion highlight the need for an inspection of the exhaust system for leaks or damage, and the rear bodywork for any signs of rust progression, which could compromise structural integrity. For the advisories pertaining to brake hose corrosion and antiroll bar play, buyers should conduct a visual inspection of all brake hoses for cracks, bulges, or leaks, and test brake pedal feel under acceleration to rule out hydraulic issues. The antiroll bar D mount play may require checking the suspension linkage for excessive movement, which could indicate worn bushings or mounts. Beyond these mechanical checks, the vehicle’s age and mileage suggest that practical due diligence should include a test drive to assess handling stability, as the suspension and steering components may exhibit signs of fatigue. It is also advisable to verify the service history for fluid changes, particularly brake fluid and coolant, as these fluids degrade over time regardless of mileage. Finally, given the prolonged periods between MOTs, a thorough inspection of the 12V battery and starter system is prudent, as standing vehicles can suffer from corrosion or electrical issues.
