2016 Yamaha Unknown 0.7L Petrol · YN16 AAX

The 2016 vehicle presented a concerning pattern of advisories across three separate MOT examinations spanning nearly five years, beginning with a successful test in April 2019 followed immediately by a failure in the same month and culminating in a clean pass in May 2023. The 2019 failure carried three distinct warnings: slight play in the front left wheel bearing, deterioration of the rear registration plate, and non-functional stop lamps. Despite the subsequent 2023 test returning a pass result, the earlier failures indicate underlying mechanical and safety issues that required attention before the vehicle regained its roadworthiness status. The gap between the 2019 failures and the 2023 success suggests that corrective action was taken on the identified problems, though the absence of intermediate test results makes it impossible to determine whether the repairs were sufficient or if new issues emerged during the interim period. Regarding mileage and usage, the available records contain insufficient data to calculate annual accumulation rates or identify rapid mileage increases, rendering any assessment of normal versus abnormal wear patterns speculative. Without a baseline odometer reading or documented mileage progression through the test periods, it remains unclear whether the vehicle accumulated distance at a rate consistent with its declared age or if significant acceleration occurred between the 2019 and 2023 assessments. The two recorded test dates—April 2019 and May 2023—represent a seven-year interval, but the intervening six-month span between the failed test and the subsequent pass provides limited insight into maintenance intervals and whether any critical systems degraded over time. The unknown mileage figure combined with the presence of persistent advisories in 2019 raises questions about whether regular servicing was maintained throughout the vehicle's lifetime. The primary mechanical concerns stem from the front left wheel bearing showing slight play, which typically manifests as a pulsating or knocking noise when traversing uneven surfaces such as potholes or gravel paths. Listen for a rhythmic vibration transmitted through the steering column or chassis when driving over rough terrain, particularly noticeable at highway speeds where the bearing load is highest. The offside front tyre condition indicates wear on the outer edge of the tyre, suggesting either underinflation, improper alignment, or reduced tread depth on that side specifically; inspect the tyre pressure and camber settings during a test drive to confirm whether the issue is localized to one wheel. The failing stop lamps represent a serious safety hazard—they must be tested functionally by verifying illumination of both front and rear units simultaneously, and if they remain dark, replacement is mandatory before the vehicle can be considered roadworthy. Additionally, the deteriorated rear registration plate, while not a direct safety risk, may compromise identification documentation and could indicate broader paint or metal degradation that might affect the vehicle's structural integrity if left unaddressed. Buyers should prioritize a thorough physical inspection of the front left suspension assembly, focusing on the bearing housing and surrounding bushings for signs of play, looseness, or excessive wear that could cause handling instability. A detailed examination of the tyre sidewall and contact patch will reveal whether the offside wear is genuine or the result of alignment drift, and the brake system should be checked for fluid leakage around the caliper housings and rotor mounts, especially given the proximity of the 2019 failure that included stop lamp malfunctions. If the original repair of the wheel bearing was performed correctly, it should now be within its expected service life, but the fact that it was replaced between 2019 and 2023 supports the recommendation to verify all suspension components with a mechanic familiar with the specific model. Finally, confirming the full functionality of the lighting system—including turn signals, brake lights, and indicators—is essential because the 2019 failure noted non-working stop lamps, and even minor electrical faults in related circuits can develop over time and create unexpected hazards during night driving.
