2020 Mercedes-Benz EQC 400 AMG Line Premium + 4M Electric · HK20 XAN

A recent failure regarding structural tyre integrity marks a significant departure from the otherwise clean testing history of this vehicle. While the 2023 and 2024 inspections recorded no defects, the 2025 MOT resulted in a dangerous failure due to a tear and structural separation on the offside rear tyre, alongside an advisory for heavy inner edge wear on the nearside rear tyre. This indicates a sudden shift from a defect-free record to a failure involving critical safety components, suggesting that while the vehicle has previously met all standards, recent tyre condition and potential alignment issues require immediate attention. The recorded mileage of 30,677 miles over approximately six years represents a low annual accumulation of roughly 5,113 miles. This usage pattern suggests the vehicle has been driven significantly less than the UK average, which typically involves higher annual mileage. Mechanically, this lower frequency of use means that while drivetrain components may have less wear, the vehicle has been subject to less frequent operation, which can sometimes lead to different wear patterns on consumables like tyres and braking systems compared to high-mileage motorway vehicles. Prospective buyers should focus specifically on the tyre and wheel assembly following the recent failure and advisory. The report of heavy wear on the inner edge of the nearside rear tyre is a specific indicator of potential suspension or alignment issues. During a test drive, it is essential to check for any steering pull to one side or a wandering sensation at cruising speeds, which could suggest that the camber or toe settings are incorrect. Furthermore, any unevenness in the steering feel or vibrations through the chassis could point to underlying issues with suspension bushes or control arms that may have contributed to the irregular tyre wear. In addition to checking the alignment, a visual inspection of the remaining tyres is necessary to ensure no other structural defects or irregular wear patterns exist. Given the dangerous failure for structural separation on the offside rear, the buyer should confirm that all four tyres are of a suitable age and condition, as the recent failure suggests that the rubber may be reaching the end of its serviceable life or has been subjected to specific road stresses. Ensure the vehicle is driven at varying speeds to listen for any rhythmic thumping or wobbling that would indicate a tyre with internal carcass damage or a compromised wheel bearing.
