2022 Mercedes-Benz EQC 400 AMG Line Premium 4M Electric · AP71 MPV

The vehicle most recently passed its MOT on 2 December 2025, although this followed an initial failure on the same day. The primary cause of failure was a major defect concerning an excessively worn nearside front suspension arm ball joint. While the 2024 test was clean, the emergence of suspension wear in the most recent cycle suggests the vehicle is entering a phase where wear-and-tear components are beginning to degrade. The overall maintenance trend is currently stable provided the ball joint was replaced, but the transition from a clean record to a major failure indicates a shift toward increased mechanical requirement. With a recorded mileage of 58,300 miles over approximately four years, this vehicle has covered an average of 14,575 miles per year. This is considerably higher than the UK average for this class of luxury electric vehicle. High annual usage typically implies more frequent motorway commuting, which is generally easier on the drivetrain but accelerates the wear of consumables such as tyres, brake pads, and suspension bushings. Prospective buyers should be aware that the higher mileage increases the likelihood of imminent replacement intervals for these items compared to a lower-mileage equivalent. Given the recent failure of the nearside front suspension arm ball joint, it is critical to verify that this repair was carried out using high-quality parts and that the offside counterpart was also inspected for similar wear. During a test drive, listen for any knocking or clunking sounds when navigating uneven road surfaces or during low-speed manoeuvring, as these are classic symptoms of worn suspension bushes or ball joints. Additionally, the minor advisory regarding windscreen damage should be assessed to ensure it has not progressed into a crack that could lead to a future MOT failure or impair visibility in direct sunlight. The buyer should also perform a comprehensive check of the tyre tread and sidewall condition, as the high mileage suggests the vehicle may be on its second or third set of tyres. Ensure there is no uneven wear on the front axles, which could indicate lingering alignment issues following the suspension repair. While the electric drivetrain is generally low-maintenance, the high usage makes it essential to review the service history for cabin filter replacements and brake fluid flushes, as these time-and-distance-based maintenance tasks are often overlooked in electric vehicles. Finally, check the condition of the brake discs for surface corrosion or scoring, which can occur if the regenerative braking system has reduced the physical workload on the calipers.
