2017 Toyota Yaris 1.3L Petrol · PL64 LAP

The 2017 Toyota Yaris received its most recent MOT test on 2025-11-03, passing with a single advisory related to the offside rear tyre exhibiting signs of damage, cracking, or perishing. This advisory, recorded under clause 5.2.3(d)(ii) concerning tyre condition, indicates a potential issue that has not yet compromised roadworthiness but warrants attention. The absence of failures in the preceding five MOT tests—from 2020 to 2024—suggests a stable maintenance history, with no evidence of worsening mechanical degradation over time. However, the presence of this advisory, particularly at this mileage, implies that the tyre has been subjected to stress or environmental exposure that may accelerate wear, and further inspection is prudent to determine the extent of the damage and whether it has progressed beyond the advisory stage. The recorded mileage of 33,589 miles for a vehicle aged nine years represents a relatively low annual usage rate of approximately 3,732 miles per annum. This is notably lower than the typical annual mileage for a similarly aged Yaris, which often exceeds 5,000 miles per year, particularly in the UK where driving conditions and usage patterns vary widely. The low mileage could suggest periods of prolonged inactivity, such as storage or infrequent use, which can lead to specific issues. For instance, standing for extended durations may cause brake discs to corrode, leading to binding calipers or uneven braking performance, while fluid degradation—particularly in the brake fluid reservoir, coolant, and transmission fluid—can accelerate over time due to stagnation. Additionally, tyre perishing from lack of rotation or exposure to environmental elements like UV light or ozone can develop, even if the vehicle is driven infrequently. Given the advisory on the offside rear tyre and the vehicle’s age and mileage, the prospective buyer should conduct a thorough inspection of the tyre’s condition, focusing on the tread depth, sidewall integrity, and any signs of dry rot or internal damage. During a test drive, listen for unusual noises from the rear axle or suspension, as uneven tyre wear or a damaged bead can cause clunking or vibration, particularly when cornering or accelerating. The buyer should also visually inspect the tyre for any cracks, bulges, or separation from the sidewall, as these can indicate a compromised tyre that may fail suddenly. If the tyre appears to be perishing, consider replacing it promptly, as this could prevent a catastrophic blowout and ensure safe operation. Beyond the tyre, the buyer should examine the vehicle’s standing corrosion, particularly around the wheel arches, rocker panels, and underbody, where moisture and road salt can accelerate rust formation. Check the brake system for signs of corrosion on the discs or binding calipers, which may result in a grinding noise when braking or reduced braking efficiency. Inspect the 12V battery and associated wiring for signs of corrosion or wear, as low mileage can lead to battery discharge if the vehicle is not used regularly. Additionally, verify the service history for fluid replacements, particularly the brake fluid, coolant, and transmission fluid, as these should be renewed at specified intervals, even if the vehicle is not driven frequently. Finally, ensure the vehicle’s service book or records are up to date, as this will provide a clear timeline for maintenance and help identify any missed servicing. If the buyer is concerned about the tyre advisory, they may also consider a professional inspection to assess the tyre’s structural integrity and determine whether it is safe to continue using or if replacement is necessary.
