2021 Mercedes-Benz CLA 1.3L Petrol · SA21 BTD

The 2021 Mercedes-Benz CLA presents a stable and improving maintenance trend, culminating in a clean pass on 23 May 2026 at 22,054 miles with zero defects recorded. This outcome is significant given the vehicle's history of tyre-related failures just twelve months prior. The most recent test confirms that all previously flagged defects were rectified, and no new advisories or failures have emerged, indicating a period of consistent upkeep leading into the current MOT cycle. The mileage profile is notably low for a five-year-old vehicle, averaging approximately 4,411 miles per year. Between the May 2024 test at 10,587 miles and the failed test on 26 May 2025 at 18,074 miles, the car covered roughly 7,487 miles in just over twelve months, suggesting a marked increase in usage during that period. The subsequent jump to 22,054 miles by May 2026 represents an additional 3,939 miles in under a year, confirming sustained but moderate use. There are no suspicious gaps or mileage anomalies in the record, and the progression appears consistent with genuine incremental accumulation. The May 2025 failure is the focal point for any prospective buyer's inspection. The tester flagged cuts to both inner rear tyres and a deeper cut penetrating to the ply or cords on the offside rear outer tyre, alongside front tyres worn close to the legal limit and exhibiting inner-edge wear. Inner-edge wear on the front tyres typically points to misaligned toe or camber settings, or worn suspension bushes and track rod ends allowing geometry drift under load. A buyer should verify the current alignment specification and inspect the front lower arm bushes, ball joints, and rear suspension components for play or deterioration. The rear tyre cuts suggest the vehicle may have encountered road debris or kerbing damage, so a thorough inspection of all four sidewalls for fresh cuts, bulges, or sidewall deformation is warranted. Given the low mileage and the nature of the defects, the car may have spent extended periods stationary, so tyre age codes should be checked to confirm no perished rubber from age-related degradation. No structural corrosion, exhaust emissions, or braking defects have appeared in the record, and the clean 2026 result suggests the vehicle is currently in sound mechanical order.
