2018 Mercedes-Benz GLA 2.0L Petrol · AF18 WDO

A significant recent failure regarding tyre structural integrity marks a departure from a previously consistent record of clean MOT results. While the vehicle maintained a series of passes without defects between 2021 and late 2024, the test on 17 November 2025 resulted in a failure due to the offside front tyre having ply or cords exposed, which is classified as a dangerous defect. Although the vehicle subsequently passed the same test on that date after the necessary repairs, the presence of this high-risk component indicates a sudden lapse in monitoring consumable wear. The vehicle's mileage of 78,779 miles over approximately eight years represents an average annual accumulation of roughly 9,847 miles. This usage pattern is consistent with typical UK driving profiles for a vehicle of this age and suggests a steady level of mechanical wear on components such as the suspension bushes, brake discs, and drivetrain. There are no significant gaps in the testing history to suggest long periods of inactivity, which generally implies that the mechanical systems have been subject to regular, albeit standard, operational stresses. Prospective buyers should pay close attention to the condition of the tyres and wheel assemblies during a physical inspection. Given the recent failure for exposed cords on the offside front tyre, it is essential to check all four tyres for uneven wear patterns, sidewall bulging, or cracking, which could indicate alignment issues or impact damage. During a test drive, listen for rhythmic thumping or vibration through the steering wheel at motorway speeds, as these symptoms can be linked to tyre defects or underlying suspension problems that may have contributed to premature tyre failure. The advisory from the November 2025 test regarding a nearside rear child seat obstructing the inspection of the adult seat belt should be noted as a procedural limitation rather than a mechanical fault. However, when seated in the rear, you should manually inspect the seat belt webbing for fraying and ensure the buckle mechanism operates smoothly without sticking. While the MOT record does not currently show issues with the braking system or chassis, the sudden appearance of a dangerous tyre defect warrants a thorough check of the front suspension components for any signs of play or knocking when navigating uneven road surfaces.
