2008 Lexus GS450H 3.5L Hybrid electric · WU08 HHW

The vehicle's overall roadworthiness remains in the unassured category, with the most recent test (September 2025) failing on a critical structural component. The 2025-09-29 test at 134,780 miles revealed a severe failure in the rear brake disc, which is a serious structural risk that has not been corrected. This indicates that the vehicle has not been maintained for over a year since the last MOT, placing it at risk of imminent failure if the current brake condition persists. The mileage trajectory is notably unstable and rapidly accelerating , reflecting a lack of proactive upkeep. The vehicle moved from 130,818 miles in October 2024 to 134,780 miles in September 2025, a gain of 3,962 miles that corresponds to roughly 400 miles per year. This acceleration is problematic because the engine and drivetrain components are likely bearing the full load of the vehicle's weight for a significant portion of the year, accelerating wear on the transmission and drivetrain. The lack of a clear "stabilization" date suggests that the owner has not taken steps to reduce the vehicle's weight or address the brake issues. Given the specific faults recorded, the buyer must inspect the vehicle for structural integrity and mechanical components. The most critical area is the rear brake disc , which must be checked for corrosion, pitting, or scoring, as this is a serious structural risk that could lead to total brake failure. Additionally, the front suspension arms and rear brake pipes must be examined for corrosion, as these are prone to failure under load. The brake calipers should also be checked for binding, as the 2024-10-01 test indicates a significant imbalance across an axle that has not been addressed. Finally, the front and rear brake discs must be inspected for corrosion, as the 2024-10-01 test confirmed they were covered in grease, which is a sign of poor maintenance that could lead to premature failure.
