2004 Lexus RX300 SE Auto 3.0L Petrol · RL04 LNG

The Lexus RX300 SE Auto most recently passed its MOT test on 27 October 2025, with the only recorded observation being an advisory notation for an oil leak assessed as not excessive under section 8.4.1 (a) (i). Looking at the broader test history, the maintenance trend is essentially stable rather than deteriorating, as the vehicle has demonstrated a clear pattern of passing its annual assessments after addressing identified defects. The October 2024 test initially recorded a failure due to a fractured nearside rear coil spring, but this was rectified within ten days, and the subsequent pass demonstrates that the suspension component was properly replaced. The recurrence of coil spring corrosion advisories on both axles is worth noting, but these were flagged as advisories rather than failures, indicating the issue was monitored rather than representing an immediate roadworthiness concern at the time of test. The recorded mileage of 166,479 miles across approximately 22 years of service equates to an annual average of around 7,567 miles, which sits broadly within the expected range for a luxury SUV of this vintage and suggests consistent, moderate usage rather than prolonged standing or unusually high wear. There is no evidence in the MOT history of erratic mileage jumps or extended gaps between tests that would suggest the vehicle was laid up for significant periods. This consistent level of use is generally favourable for mechanical condition, as regular driving tends to keep seals lubricated, prevent brake and suspension components from seizing, and maintain battery charge. However, the cumulative effect of 166,479 miles means that major drivetrain and undercarriage components will have experienced substantial wear over the vehicle's service life, even though the MOT history does not flag any major mechanical failures beyond the suspension spring. The recurring advisories relating to coil spring corrosion on both front and rear axles warrant careful attention from any prospective buyer. Coil springs on vehicles operating in the UK, particularly those used for shorter journeys or kept predominantly outdoors, are highly susceptible to surface corrosion which can progress to structural weakening and eventual fracture, as was demonstrated by the nearside rear spring failure recorded in October 2024. On a test drive, listen for any metallic clunks or rattles from the suspension over uneven surfaces, and observe whether the vehicle sits level when unladen, as a fractured or weakened spring will cause that corner to sit lower than the others. It is reasonable to expect that the fractured spring was replaced in October 2024, but the adjacent advisories suggest the remaining springs are showing signs of age-related corrosion and may require replacement in the near future as a precautionary measure. Additionally, the persistent advisories regarding rear tyre perishing and cracking indicate age-related rubber degradation, which on a vehicle of this age can affect all four tyres regardless of tread depth; inspect the sidewalls closely for hairline cracks, particularly in the areas between the tread grooves and the wheel rim, and consider replacement as a matter of routine maintenance given the calendar age of the rubber. Beyond the items flagged in the MOT history, the current advisory for a non-excessive oil leak should be investigated to determine its source, with common culprits on this generation of Lexus RX being the valve cover gasket, crankshaft seals, or transmission pan seals. On a test drive, observe whether the leak worsens after the engine has reached operating temperature, and check the underside of the engine and the ground beneath the parked car for fresh oil residue. Given the vehicle's age and mileage, it is also prudent to verify the service history for time-based maintenance items that do not form part of the MOT assessment, including the condition and age of the 12V battery, the brake fluid which absorbs moisture over time and should be replaced every two to three years regardless of mileage, the coolant which degrades in its corrosion-inhibiting properties, and the automatic transmission fluid which on high-mileage vehicles benefits from periodic replacement to maintain smooth gear changes. Inspect the brake discs for signs of corrosion around the outer edges, as standing moisture combined with age can cause surface pitting, and verify that the calipers are releasing correctly by feeling for any uneven pulling during a moderate brake application. Finally, ensure that the obligatory mirror damaged in 2023 has been replaced with a compliant unit, as this is a straightforward item to verify visually before purchase.
