2008 Lexus RX400H 3.3L Hybrid electric · GV08 LMU

The most recent MOT test for this 2008 Lexus RX400H was conducted on 2024-08-02, resulting in a passing grade despite multiple persistent advisories. However, the vehicle’s MOT history reveals a pattern of recurring corrosion-related issues and wear that has not improved over time, with two failures in the last two years. The advisories from both 2023 and 2024—particularly concerning the sub-frames, coil springs, and anti-roll bars—suggest a structural vulnerability that has not been addressed, indicating either inadequate maintenance or underlying design limitations. While the 2024 test passed, the persistence of these advisories suggests the vehicle may still be at risk of future failures unless proactive measures are taken, such as targeted corrosion protection or suspension component replacement. The vehicle’s recorded mileage of 155,027 miles over approximately 18 years equates to roughly 8,613 miles annually, which is within the expected range for a car of this age and class, particularly if it has been used for mixed purposes including commuting and leisure. However, the absence of a service history or significant mileage gaps raises concerns about potential underuse or prolonged periods of inactivity, which can accelerate wear in critical systems like brakes, suspension, and drivetrain components. The front inner suspension arm failure in 2023 highlights how standing the vehicle for extended periods can lead to pin or bush degradation, as these components are not subjected to dynamic loading. Additionally, the near-legal tyre wear advisories from previous MOTs suggest that the tyres may have been neglected, further compromising road grip and handling. Given the recurring corrosion advisories and the front inner suspension arm failure, the buyer should prioritise a thorough inspection of the vehicle’s structural integrity, focusing on the sub-frames, suspension arms, and anti-roll bars for signs of further deterioration or binding. On a test drive, listen for unusual clunks or rattles in the rear suspension, particularly when cornering or over bumps, as these may indicate worn or corroded suspension components. Check for uneven tyre wear patterns, which could signal misalignment or suspension issues, and inspect the brake system for signs of pulsation or binding calipers, which may indicate disc warping or hydraulic failure. The thin brake pads from the 2023 MOT also warrant attention, as they may require replacement soon, given the wear progression. Additionally, verify that all fluid levels—brake, coolant, and transmission—are topped up, as corrosion and standing can lead to fluid degradation over time. For the buyer, this vehicle’s age and usage history necessitate a more rigorous inspection than a lower-mileage or newer model. Beyond the MOT advisories, examine the tyre sidewalls for signs of perishing or cracking, which can compromise tyre integrity and safety. Check the 12V battery for voltage output and corrosion on terminals, as standing vehicles can lead to battery failure. Inspect the exhaust system for leaks or excessive rust, which could indicate structural weakness or emissions-related issues. Since the vehicle’s last MOT was in August 2024, consider scheduling a pre-purchase inspection by a qualified mechanic to assess the severity of the corrosion advisories and the condition of the suspension and drivetrain components. If the advisories are deemed non-critical, a follow-up MOT within six months is advisable to monitor progression. The buyer should also ensure that all scheduled maintenance—such as oil changes, filter replacements, and fluid servicing—is up to date, as the vehicle’s age means consumables may be nearing the end of their service life.
