2004 Lexus RX300 3.0L Petrol · HC04 LPA

The vehicle is currently roadworthy but the recent MOT history reveals a concerning trend of structural degradation and mechanical neglect. While it passed its latest test in September 2025 at 112,894 miles, this followed a failure just six days prior at 112,877 miles. The failure originated from excessive corrosion on the nearside rear inner suspension mounting which significantly reduced structural strength. Although the subsequent pass noted the corrosion was no longer excessive sill damage, the presence of previous repairs covered in underseal suggests the structural integrity is actively battling advanced rust. At 112,894 miles over 22 years, the Lexus averages a low annual usage of approximately 5,132 miles. However, the data shows a significant gap in records between August 2024 and September 2025, where the vehicle covered nearly 7,000 miles in a single year. The clean records from 2023 with no recorded defects contrast sharply with the high volume of faults seen recently. This low-mileage profile often leads to accelerated degradation of rubber components and dry corrosion, which is evident in the recent suspension failures. A buyer must conduct a thorough physical inspection of the underbody and suspension geometry. The tester flagged recurring issues with the suspension arm ball joint dust covers in both 2024 and 2025, indicating a failure to perform proactive preventative maintenance. The front coil springs show signs of corrosion on both sides, which requires monitoring for hairline fractures that cause sudden failure. Additionally, the recorded oil leak from the differential, while described as not excessive in 2025, should be monitored for increasing rates to ensure the seal does not fail as the vehicle continues to be used.
