2006 Lexus RX400H 3.3L Hybrid electric (clean) · LF06 AAV

The Lexus RX400H presents a remarkably clean MOT history, with five consecutive annual passes—most recently on 5 February 2026 at 118,703 miles—showing no advisories or defects across the board. This consistency suggests the vehicle has been well maintained under professional oversight, with no signs of recurring mechanical neglect or structural degradation. The absence of even minor advisories, such as tyre wear or fluid leaks, is unusual for a vehicle of this age and mileage, reinforcing the likelihood of diligent servicing. The most recent test, just five months ago, confirms the car remains compliant with current DVSA standards, though the buyer should still verify that all scheduled maintenance—particularly hybrid-specific checks—has been adhered to outside of MOT requirements. The mileage accumulation of roughly 5,935 miles per year is exceptionally low for a 20-year-old vehicle, indicating either very light usage or prolonged periods of inactivity. Between the 2022 and 2026 tests, the odometer advanced by just 13,092 miles over four years, a rate that raises questions about whether the car has been stored intermittently or used primarily for short, infrequent journeys. Such low mileage reduces wear on consumables like brakes and tyres but may also mask potential issues in less frequently stressed components, such as the hybrid battery cooling system or suspension bushes. The lack of mileage variation between tests further implies the vehicle has not been subjected to aggressive driving or heavy loads, which could have accelerated component fatigue. Given the pristine MOT record, the buyer’s primary focus should shift to components not routinely scrutinised during standard tests. The hybrid powertrain—particularly the battery cooling system and high-voltage wiring—demands immediate attention, as hybrid-specific failures often evade MOT checks but can escalate rapidly. Inspect the suspension for degraded bushes or worn coil springs, especially if the car has sat unused for extended periods, as rubber degradation can occur even without mileage. Check for binding in the brake calipers, despite the clean MOT history, as hybrid systems sometimes exhibit subtle friction issues not always caught in annual tests. Structural corrosion, though rare on Lexus models, should be verified under the chassis and wheel arches, particularly if the vehicle has been exposed to salted roads or damp storage. Finally, verify all fluid levels—including the hybrid-specific coolant—and confirm the last service interval aligns with manufacturer recommendations, as hybrid systems often require more frequent attention than conventional engines.
