2007 Lexus RX400H 3.3L Hybrid electric (clean) · M222 AAB

The 2007 Lexus RX400H exhibits a concerning maintenance trend, with two consecutive MOT failures in 2023 and 2024 at 210,321 and 210,722 miles, respectively, both recording no defects. The most recent test in March 2024, over two years ago, remains unaddressed, suggesting potential neglect or unresolved issues. While prior tests in 2021 and 2023 showed passing results, the recurring failures without recorded defects imply systemic problems, possibly related to emissions, electrical systems, or minor but persistent faults. The vehicle’s roadworthiness is uncertain, requiring further inspection to confirm compliance. Mileage progression aligns with an average of 11,091 miles annually, consistent with its 19-year age. However, the 2021-2023 period reveals irregularities: a failure in November 2021 at 196,582 miles was followed by a pass just five days later at 196,793 miles, indicating possible rushed repairs or incomplete diagnostics. Subsequent tests show gradual mileage increases, but the lack of detailed defect records limits insight into wear patterns. The sparse data suggests either meticulous maintenance or incomplete reporting, though the repeated failures raise red flags about long-term reliability. Buyers should prioritise checking the exhaust system, emissions controls, and brake functionality, as these are common failure points in older hybrids. Inspect suspension components for wear, particularly bushings and coil springs, and assess corrosion in the underbody, which can worsen over time. The absence of structural defects in MOT records is reassuring, but the vehicle’s age and mileage necessitate a thorough pre-purchase inspection to identify hidden issues. Without further data, the RX400H’s mechanical integrity remains ambiguous.
