2007 Lexus RX450H 3.5L Hybrid electric (clean) · GY57 DZC

The vehicle presents a concerning roadworthiness profile following its most recent MOT failure in December 2025 at 176,451 miles. While the car achieved clean passes in 2022 and 2024, the recent failure without recorded defects suggests a significant mechanical issue or an administrative oversight that prevented a passing grade. The maintenance trend is unstable; the transition from zero advisories in previous years to a terminal failure indicates a potential breakdown in preventative maintenance or the sudden onset of component fatigue. The mileage accumulation remains consistent with typical usage patterns for a vehicle of this age, averaging approximately 9,300 miles per year. Between December 2022 at 124,420 miles and December 2024 at 157,714 miles, the vehicle covered 33,294 miles, showing a steady rate of operation. However, the gap between the December 2023 failure at 137,725 miles and the subsequent pass just two weeks later at 138,339 miles suggests a minor, likely consumable-related fault was rectified immediately after the initial failed test. A buyer must conduct a rigorous physical inspection of the hybrid powertrain and the suspension geometry given the high mileage and the age of the chassis. The record lacks recorded advisories in previous years, which may mask gradual structural corrosion or worn suspension bushes typically affecting older RX models. Pay close attention to the condition of the lower control arms and the integrity of the brake hydraulic lines, as these are common points of failure at 170,000 miles. The unexplained 2025 failure requires a detailed diagnostic report to ensure no structural cracks or fluid leaks are currently present that the tester failed to document.
