2018 Toyota Yaris 1.5L Hybrid electric (clean) · ML02 KRL

The latest MOT test on 11 March 2026 resulted in a pass, but the overall maintenance trend is beginning to decline. While the vehicle enjoyed several clean certificates between 2021 and 2025, the most recent inspection reveals a growing list of advisories. Specifically, the recurrence of brake disc pitting and the emergence of structural corrosion on the front suspension components suggest that the vehicle is now entering a phase where age-related degradation is outpacing its low usage. The recorded mileage of 17,411 miles over approximately eight years is exceptionally low, averaging roughly 2,176 miles per year. While this suggests minimal wear on the engine and drivetrain, such low usage often indicates the vehicle has spent significant periods standing. This pattern of inactivity is typically more detrimental to certain components than regular use, as it promotes moisture retention and oxidation, which is clearly evident in the current MOT advisories regarding corrosion and brake pitting. The recurring advisories for pitted rear brake discs indicate surface oxidation caused by infrequent use or exposure to moisture without sufficient heat cycles to clear the rust. During a test drive, listen for a grinding noise from the rear or feel for a slight shudder under braking. More concerning is the corrosion noted on the front lower suspension arms and the nearside Macpherson strut. While currently deemed not seriously weakened, this is a progressive issue. A physical inspection should focus on the extent of the surface rust to ensure it has not transitioned into structural scaling, and any clunks or knocks over uneven surfaces could indicate that the suspension bushes are perishing. Given the vehicle's age and low mileage, several time-based maintenance items require verification. The buyer should inspect the tyre sidewalls for fine cracking or perishing, as rubber degrades by age regardless of tread depth. The 12V battery health should be tested, as low-use vehicles often suffer from chronic undercharging. Furthermore, check for binding brake calipers and verify the service history to ensure that engine oil and other fluids have been changed based on calendar intervals rather than mileage, as old oil can lose its lubricating properties and accumulate moisture.
