2022 Mercedes-Benz EQC 400 AMG Line 4MATIC Electric · RJ71 ABN

The vehicle's most recent DVSA examination on 22 January 2026 resulted in a PASS classification, although four advisory items were recorded alongside the test outcome. These included front and rear nearside tyres worn close to the legal limit and on the edge, plus both nearside and offside front lower suspension arm ball joints exhibiting slight play. Looking at the preceding test on 13 January 2025, a pass was achieved with a singular advisory concerning the offside front lower suspension arm ball joint showing slight play. Comparing the two tests, the overall maintenance trend appears to be gradually worsening rather than stable, with the number of advisories increasing from one to four year on year. Most notably, the suspension component flagged in 2025 has progressed from a single-sided issue to bilateral play on both front lower arms, and tyre wear has now entered the advisory stage as well, suggesting that consumable and chassis components are entering a phase of more frequent replacement. With 86,202 miles accumulated over an approximate four-year service life, this EQC is averaging around 21,550 miles annually, which is considerably higher than the typical mileage profile for a premium electric SUV of this age. Such intensive usage accelerates wear on the suspension, braking system, tyres, and general chassis hardware far beyond what a lower-mileage equivalent would experience. While the electric drivetrain itself remains relatively insulated from high mileage in terms of major mechanical degradation, the supporting mechanical infrastructure including bushes, dampers, wheel bearings, and steering components will show elevated wear. The absence of any recorded mileage gaps or discontinuities suggests the vehicle has been in consistent service, which provides some reassurance regarding active use, though it reinforces the need for thorough inspection of all wear-prone items. Particular attention should be directed towards the front suspension assembly given the recurring ball joint advisories on the lower arms. Slight play at this point typically manifests as a clonking or knocking noise when traversing speed bumps, potholes, or uneven surfaces, particularly during low-speed manoeuvring or when turning the steering from lock to lock. Uneven or feathered tyre wear across the front axle can also indicate deteriorating suspension geometry, and it would be prudent to inspect the inner and outer edges of the front tyres for any abnormal wear pattern. Given the bilateral nature of the advisory, replacement of both lower suspension arms or their ball joint assemblies should be anticipated within the short term, and a pre-purchase inspection at a specialist would be advisable to confirm whether the play has progressed beyond advisory threshold. The cost of replacing these components on a Mercedes-Benz platform can be substantial, so budgeting for imminent suspension refurbishment is sensible. Beyond the flagged items, a prospective buyer should perform several supplementary checks relevant to a high-mileage, four-year-old electric vehicle. The tyres themselves warrant close scrutiny for age-related sidewall cracking or perishing, which can occur even with adequate tread depth, and the rear nearside tyre should be checked for any remaining usable tread or whether replacement has already been carried out. Brake discs on a high-mileage vehicle often exhibit lipping and corrosion around the circumference, and given the regenerative braking characteristics of the EQC, the rear discs and pads may show minimal wear while the front items could be approaching replacement interval. Although the EQC lacks a traditional combustion powertrain, the brake fluid, coolant, and reduction gearbox fluid all remain subject to calendar-based degradation and should be serviced according to manufacturer schedules. The 12V auxiliary battery, which is critical for system boot-up and ancillary functions on electric vehicles, should be tested for state of health, as failure can result in significant inconvenience. Finally, verifying that the high-voltage battery State of Health is within manufacturer tolerance and reviewing the digital service record for consistent main dealer or specialist attention would complete a comprehensive evaluation.
