2020 Mercedes-Benz EQC 400 AMG Line Premium + 4M Electric · OV20 BHO

The most recent MOT test on 2026-09-01 resulted in a passing outcome, though the vehicle’s roadworthiness history reveals a pattern of recurring advisories related to front suspension ball joints and a critical failure in 2024. The advisories from 2024 and 2025 indicate persistent minor play in the front suspension arms, specifically the spring link arms of both near-side and off-side ball joints, which are part of the vehicle’s control arm assemblies. While these findings were classified as advisories rather than failures, their recurrence suggests a potential underlying issue with the suspension bushings or mounting integrity, warranting closer attention. The failure in 2024—where the near-side rear road wheel fractured—was deemed dangerous and would have necessitated immediate repair, indicating a structural or fatigue-related problem in that wheel assembly. This failure, combined with the advisories, suggests that the vehicle’s suspension and wheel components have experienced wear beyond typical expectations, hinting at either under-maintenance or cumulative stress from usage patterns. The vehicle’s recorded mileage of 36,367 miles at the time of this assessment aligns with a moderate annual usage rate of approximately 6,061 miles per year, which is within the expected range for a six-year-old EQC given its performance and market positioning. However, the mileage does not appear to reflect a consistent, high-demand driving profile, as the gap between the 2024 failure and subsequent MOT tests spans over two years, during which the vehicle may have been stored or driven less frequently. Lower-than-expected mileage could imply prolonged periods of inactivity, which can exacerbate issues like corrosion from standing, fluid degradation, and component dry-rotting, particularly in the suspension and wheel systems. Conversely, if the vehicle was driven more heavily, the wear on consumables such as brake pads, tyres, and fluids would be accelerated, though the advisories suggest suspension components were not the primary focus of wear in this case. Given the recurring suspension advisories and the critical failure history, the prospective buyer should conduct a thorough inspection of the front and rear suspension systems. Focus on the control arms, ball joints, and spring link arms, checking for any additional play, excessive noise (clunks or rattles), or uneven ride height that may indicate further wear. During a test drive, listen for abnormal suspension noises, particularly when navigating bumps or corners, as this could reveal further deterioration in the bushings or mounting points. The fractured rear wheel from 2024 suggests that the wheel studs, brake system, or wheel bearing may have been compromised, so verify that the wheel is securely mounted and that there is no corrosion or binding in the brake calipers or discs. If the wheel was replaced, ensure the new wheel meets the vehicle’s specifications and that the brake system has been serviced to prevent potential issues like shuddering or reduced braking efficiency. For practical checks beyond the MOT findings, the buyer should examine the vehicle’s tyres for signs of sidewall perishing or cracking, which can weaken the tyre structure and compromise safety, especially given the vehicle’s age. Inspect the 12-volt battery for signs of corrosion around terminals or a weakened hold on the battery tray, as prolonged inactivity can lead to battery failure. Check the fluid levels and condition of the brake fluid, coolant, and differential fluid, as these fluids degrade over time even when not actively used, and their degradation can lead to system failures. Additionally, verify that the service book or maintenance records are up to date, particularly for the suspension and wheel components, to ensure that any repairs from the 2024 failure were completed properly and that no further issues have arisen. If the vehicle has been stored for extended periods, consider a more comprehensive inspection of the exhaust system for corrosion or leaks, as well as the electrical system for any signs of wear or failure, which can become more critical with age.
