2022 Mercedes-Benz EQC 400 AMG Line 4MATIC Electric · KM22 MSX

The vehicle most recently passed its MOT on 11 April 2026, but the history reveals a concerning trend regarding the front suspension. Specifically, the advisory for slight play in the nearside front lower suspension arm ball joint has appeared in two consecutive annual tests. This indicates that the component is deteriorating and the issue has remained unaddressed, suggesting a maintenance approach that prioritizes minimum legal compliance over preventative mechanical upkeep. With a recorded mileage of 41,840 miles over approximately four years, the vehicle has averaged around 10,460 miles per annum. This represents a typical usage profile for a premium electric vehicle of this class. Such consistent mileage is generally beneficial for the high-voltage battery system as it avoids the risks associated with long-term stagnation, though it ensures that wear on suspension bushings, tyre treads, and braking components is commensurate with its age and distance traveled. During a test drive, the buyer should be particularly alert for any knocking or clunking sounds emanating from the front nearside area when traversing uneven road surfaces or during low-speed maneuvering, as these are classic symptoms of a failing ball joint. Furthermore, the 2025 record noted edge wear on both front tyres, which often points to incorrect wheel alignment or worn suspension components. It is recommended to inspect the current tyre tread depth and examine the inner and outer shoulders for uneven wear, which would necessitate a professional four-wheel alignment. Particular attention should be paid to the braking system, specifically the rear discs. The 2025 advisory regarding pitting and corrosion on the inner face of the nearside rear disc is common in electric vehicles due to the heavy reliance on regenerative braking, which leaves the physical discs underutilised and prone to oxidation. The buyer should check for brake shudder during deceleration and inspect the discs for significant scoring or heavy rust. Ensuring the calipers are not binding is essential to maintain efficiency and prevent premature tyre wear.
