2010 Lexus RX450H 3.5L Hybrid electric · WK10 FJO

The vehicle remains roadworthy but the maintenance history shows a worsening trend regarding structural integrity and recurring mechanical wear. While the most recent test in April 2024 at 172,364 miles was a pass, the introduction of corroded inner sills represents a significant concern for a vehicle of this age. This follows a pattern of persistent suspension issues that have been flagged across several years, suggesting that while minor faults are addressed, the underlying chassis and components are now requiring closer attention. At 172,364 miles over 16 years, the Lexus has averaged approximately 10,773 miles per year, which aligns with typical usage patterns for a premium SUV of this era. The records show consistent operation, with a 6,339-mile interval between November 2020 and May 2021, and another 6,900 miles in the following 18 months. This regular mileage suggests the vehicle has not sat idle for long periods, but the high mileage places considerable stress on rubber components and bearing assemblies. A buyer must prioritize a thorough inspection of the inner sills to determine the extent of the corrosion noted in the 2024 test, as structural rust can lead to expensive repairs if left untreated. The history reveals a chronic issue with rear suspension arm bushes, with worn components noted in 2021, 2023, and again during the previous failure. Furthermore, the nearside front wheel bearing showed slight play in both 2020 and 2024, indicating that this component has not been replaced and is likely nearing failure.
