2010 Lexus RX450H 3.5L Hybrid electric (clean) · CE60 KLO

A consecutive run of eight clean pass results with no advisories or failures recorded from 2018 through the most recent test on 2 October 2025 represents an unbroken track record of roadworthiness at the official test level for this Lexus RX450h. Across every annual examination during this eight-year window, the vehicle has presented without any defects noted, which on a 16-year-old hybrid SUV is a notable absence of flagged wear items such as corroded brake pipes, perished suspension bushes, or exhaust deterioration that typically accumulate with age. The stability of this pattern, with identical pass outcomes year after year, indicates that no component has yet reached the threshold of examiner concern, though the MOT test is a snapshot of safety and emissions compliance at the time of examination rather than a measure of mechanical condition more broadly. With 167,213 miles accumulated, the lack of recorded advisories is consistent with a vehicle that has either been conscientiously rectified between tests or one whose wear items have not yet deteriorated to a flaggable level, and a prospective buyer should not infer more from this record than the official data supports. The mileage profile of 167,213 miles over approximately 16 years equates to a consistent annual accumulation of around 10,450 miles, which is broadly typical for a vehicle of this age and class and points to regular rather than sporadic use. There are no extended gaps between tests in the recorded history, with annual examinations consistently filed from 2018 through 2025, suggesting the car has remained in active service throughout this period rather than being laid up. Given the high overall odometer reading, attention should nevertheless be directed at the mechanical implications of sustained high mileage: hybrid system battery health, engine oil consumption on the 3.5-litre V6 Atkinson-cycle petrol unit, transmission fluid condition in the electronically controlled continuously variable transmission, and the state of the regenerative braking system's conventional friction brakes are all areas where wear is proportional to distance covered rather than age alone. The absence of MOT advisories does not substitute for verification of these higher-mileage-specific items by a Lexus specialist or independent hybrid technician. For a pre-purchase inspection, the absence of recorded advisories means a test drive carries greater diagnostic weight than usual, as there are no specific flagged components to focus on from the MOT history. On the road, listen for any hesitation, irregular vibration, or unexpected engine running between accelerating and coasting, which would suggest the hybrid synergy drive system is switching between electric and petrol propulsion unevenly, and pay close attention to whether the transition between power sources is seamless or accompanied by a shunt. At low speed, listen for any whining or clonking from the front axle area consistent with worn drive shafts or transmission components, and check for any binding or pulling under light braking that could indicate a seized rear caliper, a known weakness on high-mileage Toyota and Lexus hybrids where the electric parking brake and rear caliper mechanisms can corrode from infrequent use. Under deceleration, a soft or spongy pedal feel, or any warning light for the brake system, should prompt immediate further investigation of the brake booster and accumulator, both of which are expensive items on this platform. With suspension, push down firmly on each corner and release to confirm the vehicle settles once and remains stable rather than oscillating, which would indicate weakened dampers, and listen for clonks or creaks over speed humps and uneven surfaces that could betray worn anti-roll bar links, strut top mount bearings, or lower control arm bushes. Inspect the underside and inner arches for any surface corrosion or fluid residue, paying particular attention to the fuel tank area, rear subframe mounting points, and the brake pipe runs along the chassis rails, as corrosion in these locations is a common reason for later-life MOT failures on Lexus SUVs of this vintage. The hybrid system battery cooling fan in the rear cabin area should be verified as operational, and the 12V auxiliary battery, which is prone to failure on high-mileage examples and can cause a cascade of false error codes, should be load-tested as part of any inspection. Given the recorded mileage is well above the typical lifespan threshold for original hybrid battery packs, a specialist health check of the high-voltage traction battery cell balance and state of charge is strongly advisable before purchase, as replacement costs for this component remain substantial even on a car of this age.
