2007 Lexus RX400H 3.3L Hybrid electric · ML07 KZR

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend in suspension and steering component integrity. While it passed its latest test in December 2025 at 220,873 miles, this followed two significant failures within a single week that highlighted multiple mechanical deficiencies. The most recent pass still noted a slight play in the nearside rear anti-roll bar ball joint, indicating that while the owner addressed the critical failures, the underlying wear on the high-mileage suspension system is reaching a terminal stage of its service life. At 19 years old, the recorded mileage of 220,873 represents a consistent annual usage of approximately 11,600 miles, which is typical for a luxury hybrid vehicle of this age. However, the data shows a rapid accumulation of over 37,000 miles between December 2023 and December 2025. This high-intensity use period correlates with the accelerated degradation of rubber components and ball joints, moving from minor wear on bushes in previous years to multiple failures of ball joints and steering linkages within a short window. A buyer must conduct a thorough physical inspection of the rear subframe and lower suspension arms, as the December 2025 failure specifically flagged subframe corrosion and corroded front coil springs. The record shows a recurring pattern of worn suspension bushes and leaking shock absorbers, which suggests the entire geometry assembly is under significant stress. Particular attention should also be paid to the hybrid system fault noted in 2024 and the persistent front oil leak that has appeared in the last three tests, as these represent potential high-cost mechanical risks beyond simple consumable wear.
