2004 Lexus RX300 3.0L Gas bi-fuel · RF04 TZP

The most recent DVSA MOT test for this 2004 Lexus RX300 occurred in February 2022, where it passed with two advisories—an oil leak that was deemed not excessive and front brake discs that were worn but not seriously compromised. The preceding MOT history reveals a pattern of consistent passing tests with only minor advisories, though there are occasional failures, particularly in 2016, related to parking brake efficiency, brake disc wear, and rear exhaust support pin issues. These failures suggest some recurring mechanical concerns, particularly with braking systems and suspension components, but the overall trend in the past four years has been stable, with no evidence of rapid deterioration. The advisories, while not failing grades, indicate areas requiring attention before they reach critical levels, and their persistence may warrant closer inspection during purchase. The vehicle’s recorded mileage data is insufficient for a precise assessment, but the MOT history spans a period where the car appears to have accumulated significant mileage over time. The most recent MOT in February 2022 would likely place the RX300 in the mid-to-high 100,000-mile range, given its 2004 model year and typical UK usage patterns. The gaps between MOTs—particularly the two-year interval from 2018 to 2020—suggest periods of either low or inconsistent usage, which could have contributed to the observed wear patterns, such as brake pad thinning and suspension component deterioration. If the vehicle has been driven at a moderate rate, the wear advisories may reflect normal usage, but if it has been driven heavily or stored under harsh conditions, the suspension and braking systems could be approaching more urgent maintenance needs. For a prospective buyer, the most critical areas to inspect during a physical examination and test drive are the braking system and suspension components. The front brake discs show recurring wear advisories, indicating that the pads have thinned significantly, and the discs may have pitting or scoring. On a test drive, listen for uneven brake pedal response, a grinding noise when applying brakes, or a vibration or shudder that could signal warped discs or fading pads. Check for brake fluid leaks under the vehicle and inspect the brake discs for excessive thickness reduction—if they are below 1.5mm in thickness, replacement is strongly advised. Additionally, the suspension advisories, particularly regarding deteriorated anti-roll bar mounts and suspension arm bushings, suggest that the vehicle may exhibit clunking noises from the rear suspension when driving over bumps or uneven surfaces. Inspect the suspension for excessive play or binding, and check for oil leaks around the engine bay and undercarriage, as the oil leak advisory may stem from a worn oil seal or valve cover gasket. Beyond the mechanical checks, given the vehicle’s age and the advisories present, it is advisable to conduct a thorough inspection of the following items: the front wiper blades, which have been worn in previous MOTs, should be replaced to ensure clear vision in adverse weather; the exhaust system, particularly the rear exhaust box support pin detachment in 2016, indicates a potential for further structural failure if not repaired, so a visual check for cracks or loose components is essential; and the battery, which should be tested for voltage and corrosion, especially if the car has been stored for extended periods. For fluid servicing, given the age of the vehicle, check the brake fluid, coolant, and transmission fluid for degradation, as these fluids can become contaminated or lose effectiveness over time. Finally, verify the service book for any recorded maintenance history, particularly for suspension and braking system servicing, as this will help gauge whether the advisories have been addressed or if further work is pending.
