2013 Lexus RX 450H Premier CVT 3.5L Hybrid electric · LM63 OLO

The vehicle remains roadworthy but the maintenance history shows a worsening trend regarding structural corrosion and consumable component wear. The most recent test in September 2025 at 46,542 miles identified both front and rear brake discs as pitted and scored. This follows the 2024 inspection where the sub-frame and rear suspension arms were first flagged for corrosion. While the vehicle consistently passes its tests, the progression from general corrosion to specific component degradation suggests that environmental damage is accelerating. The mileage profile is exceptionally low for a thirteen-year-old vehicle, averaging approximately 3,580 miles per year. There is a notable gap in usage between February 2022 at 29,274 miles and October 2024 at 41,925 miles, suggesting long periods of inactivity. This pattern explains several observed issues, as the recurring advisories for perishing and cracking tyres in both 2023 and 2024 indicate that the vehicle likely sits for extended durations, leading to rubber dry rot rather than mechanical tread wear. A buyer must conduct a thorough inspection of the underbody to assess the depth of the corrosion on the sub-frame and suspension mounting points. Because these issues have appeared in three consecutive tests since 2023, structural integrity is at long-term risk if oxidation is not monitored. The braking system also requires immediate attention, as the transition from thin pads to scored discs indicates a need for comprehensive replacement. Given the low mileage, the tyres should also be checked specifically for sidewall cracking, as the age of the rubber likely exceeds its safe service life despite the remaining tread.
