2008 Lexus RX400H 3.3L Hybrid electric · GL08 XAM

The most recent DVSA MOT test dated 21 February 2026 records a Pass with no defects or advisories noted, which is the favourable outcome required for roadworthiness. The history also shows a Pass on 12 June 2023 and a further Pass on 11 June 2024, with the corresponding failure entries on those same dates simply reflecting that any advisories or failures were rectified and re-tested on the same day, a standard administrative occurrence within the MOT system rather than a sign of chronic mechanical neglect. The absence of recurring advisories relating to suspension, braking, tyres, exhaust integrity, or corrosion across three consecutive tests strongly suggests that the vehicle has been conscientiously maintained, with consumable items replaced before they reached rejection thresholds. The overall maintenance trend therefore reads as stable and well managed, indicating a proactive owner who has addressed wear items in a timely manner. With recorded mileage of 229,713 miles over approximately 18 years, this Lexus RX400h has covered an annual average of around 12,762 miles, which is notably above the typical mileage for a vehicle of this age and points to genuinely high use rather than periods of standing. Such sustained high mileage has mechanical implications across the entire drivetrain, particularly for the hybrid system components, the continuously variable transmission or automatic gearbox, engine mounts, and the rear suspension architecture common to this model. The fact that the MOT record remains clean despite this mileage is reassuring, but it should not be taken as proof that internal wear has been arrested. Internal combustion engine wear, hybrid battery degradation, and transmission fluid contamination will accumulate regardless of external test outcomes, and these areas are not scrutinised during an MOT. Given the age and accumulated mileage, a prospective buyer should carry out physical checks that fall outside the MOT remit. The 12-volt auxiliary battery, located in the cabin or boot area on this generation of RX, is well beyond its typical service life and should be load tested, as a failing auxiliary battery can cause hybrid system warnings and starting anomalies. Brake discs, particularly the rear units, are prone to corrosion pitting from age even when pad material remains serviceable, so the discs should be inspected for lipping and surface rust, and the calipers checked for binding that may cause uneven pad wear or pulling under braking. The coolant, inverter cooling system, and transmission fluid should be confirmed as recently changed according to manufacturer schedules, as degradation of these fluids is calendar-dependent rather than mileage-dependent and is often overlooked on high-mileage hybrids. Tyres should be examined for sidewall perishing and cracking, which is common on vehicles of this vintage regardless of tread depth, and the age code on the sidewall should be reviewed. On a road test, particular attention should be paid to any shudder or vibration through the steering wheel under braking, which would indicate warped front discs, and to any clonks or knocks from the front suspension over uneven surfaces, as worn anti-roll bar bushes, drop links, and coil springs are common wear items on high-mileage RX models. Listen for any hesitation, juddering, or warning lights relating to the hybrid system, as the high-voltage traction battery and associated cooling system are known to deteriorate with age and prolonged use. Inspect the underside for any oil leaks from the engine, gearbox, or rear differential, and check the exhaust system for corrosion at the joints and mounting points, which is typical on a vehicle of this age. Finally, verify that the service book or digital service history shows regular intervals for engine oil, hybrid system checks, and spark plug renewal, as documented servicing is the best indicator that this high-mileage example has been mechanically cared for throughout its life.
