2006 Lexus RX400H 3.3L Hybrid electric · LB56 RWK

The vehicle remains roadworthy, but the maintenance history reveals a worsening trend in suspension wear and component degradation. While the most recent test in December 2025 at 171,556 miles was a pass, it introduced new issues such as oil misting the offside front shock absorber and uneven wear on the nearside front tyre. This follows a pattern of recurring failures in suspension bushes and ball joints, suggesting that the heavy-duty Lexus components are reaching the end of their functional life and require more proactive replacement. At 171,556 miles, this RX400H has averaged approximately 8,600 miles per year, which is consistent with typical UK use for its age. The data shows steady annual accumulation, with roughly 12,000 to 13,000 miles covered between each interval from 2022 to 2025. This consistent mileage suggests the car has not sat stationary for long periods, but the high mileage has placed significant stress on the rubber-based suspension components and steering system noted in the record. A buyer must prioritise a thorough inspection of the entire suspension geometry, as the record consistently flags deteriorated ball joint dust covers and worn trailing arm bushes. The steering rack showed slight free play in late 2024, a critical area that should be verified to ensure it has not progressed into mechanical failure. Additionally, the central exhaust leak identified in 2024 remains unaddressed in the 2025 record, indicating that the owner may only perform the minimum repairs necessary to pass the test. The corrosion on the rear anti-roll bar noted in 2025 should also be monitored to ensure it does not eventually compromise the structural integrity of the subframe.
