2015 Toyota Yaris 1.4L Diesel · YJ15 RTG

The 2015 Toyota Yaris presents a stable and improving maintenance trend, culminating in a clean pass on 26 July 2025 at 103,786 miles with zero defects recorded. That result is the most recent MOT entry available, sitting nearly eleven months before today's date of 16 June 2026, meaning the certificate is now expired and a fresh test will be required before the vehicle can legally return to the road. The trajectory over the past three years is encouraging. After two consecutive years of tyre-related failures in 2023 and 2024, the car has since passed cleanly on both attempts, suggesting the previous owner addressed the underlying neglect and brought basic consumable upkeep back on track. The mileage accumulation tells a consistent story. Between the July 2023 test at 77,093 miles and the July 2024 test at 90,560 miles, the car covered roughly 13,467 miles in twelve months, a step up from the earlier average but still within normal parameters for a small commuter vehicle. The following year saw a much gentler 13,226 miles added between July 2024 and July 2025, maintaining the overall lifetime average of approximately 9,435 miles per year. There are no suspicious gaps or sudden drops in recorded mileage, and the annual test dates have remained tightly clustered around late July, indicating a predictable ownership pattern rather than long periods of disuse. The recurring theme across the failure history is tyre condition. In the July 2023 test at 77,093 miles, the nearside front outer tyre had exposed ply or cords in the sidewall, a serious structural defect that points to either prolonged neglect or impact damage. The following year, both front tyres were flagged again, this time for tread depth and edge wear. Two consecutive years of tyre advisories or failures suggest the previous owner was not routinely inspecting tyre condition or alignment settings. A buyer should therefore pay close attention to the current tyre set, checking for uneven wear patterns that could indicate tracking issues or worn suspension bushes. Beyond tyres, the 2023 failure also included an inoperative offside registration plate lamp, a minor electrical item that was evidently corrected for the subsequent retest. With a clean bill of health at the last test and no structural, braking, or suspension defects on record, the mechanical risk profile is low for a vehicle of this age and mileage. A prospective buyer should still inspect the underside for corrosion, particularly around suspension mounting points and brake lines, and verify that the brake discs and pads remain in good condition given the mileage carried. The exhaust system and emissions performance also warrant a brief check, as these are common deterioration points on small petrol engines that have covered over 100,000 miles. Overall, the MOT record reflects a vehicle that has moved from a period of neglect into competent maintenance, but the expired certificate means a fresh roadworthiness assessment is essential before purchase.
