2004 Lexus RX300 3.0L Petrol · DG04 DGE

Structural corrosion and deteriorating suspension components now define the mechanical profile of this vehicle, as evidenced by the latest pass on 29 February 2024. While the record remained clear for several years, a trend of degradation has emerged, moving from perishing tyres in 2020 to a dangerous tyre failure in 2023, and culminating in current advisories regarding cracking rear subframe bushes and corrosion of the rear subframe. An average annual accumulation of approximately 4,936 miles is low for a vehicle of this age. This usage pattern is consistent with the recorded defects, as low-mileage vehicles often experience the premature perishing of rubber components due to lack of regular flexion and prolonged periods of standing. This is reflected in the history of tyre cracking and the current state of the subframe bushes. Attention must be paid to the rear chassis and suspension. The recorded corrosion of the rear subframe and the cracking of the nearside and offside rear bushes require a physical inspection to determine the extent of the metal loss and rubber fatigue. During a test drive, listen for knocking or clunking sounds coming from the rear of the vehicle when traversing speed bumps or uneven road surfaces, as worn subframe bushes often cause instability or audible movement. The recurring issue of an insecure battery, flagged in both 2023 and 2024, indicates a failing bracket or missing fastener that should be rectified to prevent movement. Additionally, given the dangerous tyre failure in 2023 and the general perishing noted in 2020, a thorough check of the current tyre sidewalls for similar cracking or bulges is necessary to ensure the rubber has not degraded again.
