2021 Mercedes-Benz A 1.9L Diesel · RO71 GFJ

Recurring tyre degradation and sidewall damage represent the primary mechanical concern for this vehicle, evidenced by a pattern of advisories and a dangerous failure regarding exposed cords. While the most recent test on 10 September 2026 resulted in a pass, the record shows a persistent issue with tyre condition, specifically regarding cracking, perishing, and damage to the offside tyres. This trend of tyre-related defects, including a significant failure in September 2024 where the nearside front tyre had ply or cords exposed, suggests that the rubber components are reaching the end of their functional life or are being subjected to environmental degradation. The vehicle has covered 28,280 miles over approximately five years, which equates to an average annual usage of roughly 5,656 miles. This represents a low-mileage profile for a 2021 model. While lower annual mileage typically implies less wear on drivetrain components and braking systems, the MOT history indicates that the tyres may be suffering from age-related perishing rather than tread wear from heavy use. Low-use vehicles can often experience rubber hardening and sidewall cracking due to extended periods of inactivity or exposure to the elements, which aligns with the repeated advisories for cracking and perishing across multiple testing cycles. A prospective buyer should pay close attention to the condition of all four tyres, as the recent advisory for cracking and perishing on both the offside front and offside rear tyres indicates that replacement may be imminent. During a test drive, it is essential to monitor for any vibrations through the steering wheel or unusual road noise, which could indicate structural irregularities in the tyre sidewalls or uneven wear. Furthermore, the repeated mention of defective windscreen wiper blades across the 2025 and 2026 tests suggests a need to verify that the wiper motor and linkage are functioning smoothly and that the blades do not streak or chatter during use. Given the history of tyre-related failures, a thorough visual inspection of the tyre sidewalls for any further cuts, bulges, or deep cracks is necessary. While the 2024 failure for exposed cords was rectified, the continued advisories for perishing suggest the rubber is becoming brittle. Ensure that the tyre replacement history is verified to confirm that the current set is not merely a temporary fix for a wider issue of age-related degradation. Check that the steering feels consistent and that there is no pulling to one side, which would help rule out any secondary issues resulting from the previous tyre defects.
