2020 Mercedes-Benz EQC 400 AMG Line 4MATIC Electric · AF70 OBT

A recurring concern with the front suspension ball joints and tyre condition dominates the recent MOT record. The vehicle failed the 2025‑11‑10 test because the off‑side front suspension arm ball joint was deemed excessively worn, and it carried advisories for slight play in the nearside front ball joint and for cracking or perishing on both rear tyres. The following day the car passed, but the same front‑ball‑joint play and rear‑tyre advisories remained, indicating that the underlying wear has not been remedied. An earlier 2024 advisory highlighted nearside front tyre wear close to the legal limit, while the 2023 test recorded no defects, suggesting a deterioration in suspension and tyre health over the last two years. At 44,867 mi recorded over roughly six years the annual accumulation averages about 7,500 mi, which sits comfortably within typical UK usage patterns for a 2020 model. There are no significant gaps between tests, so the mileage appears to reflect regular, steady driving rather than prolonged storage. This moderate mileage means consumable wear such as brake pads, clutch, and drivetrain components is likely to be within normal limits, but the documented tyre and suspension issues should be expected to become more pronounced as the remaining mileage diminishes. When inspecting the vehicle, focus on the front suspension ball joints: check for any perceptible play when the steering wheel is rocked at a standstill, listen for clunking or knocking noises when driving over potholes or uneven road surfaces, and feel for any wandering or vague steering response at speed. Examine the condition of the front and rear tyres for visible cracking, sidewall bulges, or uneven tread wear that could indicate internal damage; feel for hard spots and verify that the tread depth meets the legal minimum. Any indication of excessive vibration, especially through the steering column or at the rear, may point to deteriorating tyre integrity or worn suspension components. Given the documented front‑ball‑joint wear and tyre degradation, a prospective buyer should budget for replacement of the off‑side front ball joint and likely the nearside front ball joint if play persists, together with a full tyre set if the rear tyres show the advised cracking. After any suspension work, a professional alignment is essential to prevent premature tyre wear. No other failures have been recorded, so aside from these targeted items the vehicle’s MOT history does not reveal additional mechanical concerns.
