2006 Lexus RX400 H SE CVT 3.3L Hybrid electric · DA56 DLV

The roadworthiness of this vehicle is currently compromised due to a worsening trend in structural integrity and mechanical wear. The most recent test in February 2024 at 199,932 miles resulted in a significant failure involving critical structural defects. Specifically, the tester identified excessive corrosion on the rear suspension component mounting areas on both sides of the sill, which significantly reduced structural strength. This represents a severe degradation from the 2021 records where similar corrosion was noted but described as not yet being seriously weakened. The vehicle shows a consistent usage pattern, averaging approximately 10,000 miles per year over its twenty-year life. Between the December 2021 test at 185,132 miles and the February 2024 test at 199,932 miles, the car covered 14,800 miles, indicating regular operation. However, the current date of June 2026 means the vehicle has not had an MOT in over two years. This gap creates significant uncertainty regarding the current state of the structural repairs and the mechanical components flagged during the last failure. A buyer must conduct a thorough physical inspection of the sills and rear sub-frame to determine if the structural corrosion has progressed beyond repairable. The history reveals a recurring pattern of suspension fatigue, specifically with trailing arm bushes and anti-roll bar bushes failing repeatedly between 2021 and 2023. The 2024 failure also introduced steering rack inner joint play and a leaking front shock absorber, suggesting the front suspension is now reaching the end of its life. The presence of deep cuts reaching the tyre cords in the last test further indicates a lack of basic preventative maintenance by the previous owner.
