2021 Toyota Yaris Dynamic HEV CVT 1.5L Hybrid electric (clean) · LR71 UPO

The latest MOT test outcome for the 2021 Toyota Yaris Dynamic HEV CVT reflects a critical failure at its most recent inspection, with the vehicle failing under the category of "Dangerous" due to a near-side front tyre exhibiting a structural lump caused by separation or partial failure of its sidewall. This marks a stark deviation from the previous two MOTs, which were both passed without any recorded defects, suggesting either a sudden mechanical issue or an undetected pre-existing condition that has escalated. The presence of a "Dangerous" failure indicates an immediate roadworthiness concern, as the tyre’s integrity cannot be relied upon to prevent catastrophic failure during operation. Buyers must prioritise addressing this defect urgently to ensure the vehicle’s safety and compliance with legal standards. The recorded mileage of 9,010 miles for a vehicle aged five years represents an unusually low annual usage rate of approximately 1,802 miles per annum, which is significantly below the average for its age. Such low mileage may imply periods of prolonged stationary use, particularly if the vehicle was parked in a garage or exposed to environmental conditions that accelerate wear from standing—such as brake corrosion, suspension binding, or fluid degradation. However, the sudden tyre failure suggests that the vehicle may have been subjected to dynamic stress or misuse, such as excessive cornering, rough road conditions, or improper tyre maintenance, which could have contributed to the sidewall separation. Buyers should consider whether the vehicle’s low mileage aligns with its operational history, as standing can exacerbate hidden issues like caliper binding, brake disc warping, or suspension component wear, all of which may not be apparent during routine checks. Given the critical tyre failure, the prospective buyer must conduct a thorough inspection of the near-side front tyre to confirm the extent of the damage and rule out any secondary issues. During a test drive, listen for unusual noises from the front wheels, such as clunking or vibration, which may indicate misalignment, suspension wear, or further tyre degradation. Inspect the tyre’s tread depth and sidewall for any additional cracks, bulges, or signs of separation, and verify that the vehicle’s alignment is correct to prevent uneven wear. The near-side front tyre should be replaced immediately, as the risk of sudden blowout or structural failure remains high. Additionally, the buyer should check the vehicle’s brake system for signs of corrosion or binding, particularly on the near-side front calipers and discs, as prolonged standing can lead to moisture ingress and rust accumulation, compromising braking performance. For the buyer to proceed with a more comprehensive assessment, they should also examine the vehicle’s suspension components, focusing on the front suspension bushes and coil springs for signs of wear, cracking, or excessive play. The CVT transmission and drivetrain should be inspected for unusual noises or resistance during acceleration, as low mileage combined with potential misuse could indicate early signs of transmission or drivetrain stress. Fluid levels, particularly the CVT fluid and brake fluid, should be checked for contamination or degradation, as these fluids degrade over time regardless of mileage. If the vehicle has been stationary for extended periods, the 12V battery should be tested for voltage output and corrosion on terminals, while the exhaust system should be inspected for leaks or corrosion, especially if the vehicle has been exposed to damp conditions. Lastly, the buyer should verify that the vehicle’s service history aligns with the manufacturer’s recommendations, particularly for fluid changes and tyre rotations, to mitigate any hidden wear from low mileage or standing.
