2022 Mercedes-Benz EQC 400 AMG Line Premium 4M Electric · YK22 NKA

The most recent DVSA examination recorded on 6 February 2026 returned an Advisory-free pass with no defects noted, indicating that any previously flagged items were satisfactorily resolved at the time of test. However, the same date also carries a failure entry against major defects at both front suspension arm ball joints, which means the vehicle did not pass first attempt that day and required rectification before the pass was issued. It is reasonable to infer that the lower arm ball joint assemblies were replaced between the failure and the subsequent pass on the same date, since the second result is clean. The 2025 test history adds context: a pass with an advisory concerning front brake disc wear, pitting, and scoring on both sides. Taken together, the trend suggests a vehicle that has been actively maintained but is now showing wear items consistent with its accumulated mileage, particularly at the front axle where braking and steering loads are highest. With 52,312 miles recorded over approximately four years, this EQC is averaging around 13,000 miles annually, which sits at the upper end of typical usage for a premium electric SUV. There is no evidence of extended standing periods or significant mileage gaps in the supplied record, and the consistent annual accumulation points to regular use, most likely a mix of motorway and urban driving. For an electric vehicle of this age and mileage, this usage profile is broadly favourable for mechanical health, as regular cycling helps preserve battery state of charge, keeps brake components functional, and prevents the deterioration often associated with prolonged standing. The principal wear implications relate to consumables rather than the high-voltage powertrain, with suspension joints, brake discs and pads, tyres, and underbody protection being the items most likely to require attention. Given the recorded failure for both nearside and offside front suspension arm ball joints, the prospective buyer should establish precisely what components were fitted and confirm whether genuine Mercedes-Benz or equivalent OE-quality items were used. Aftermarket or inferior ball joint replacements on a multi-link front axle can wear prematurely and may compromise geometry settings, so a post-repair wheel alignment certificate should be requested. On a test drive, listen carefully for any clonking or knocking from the front suspension over speed humps, rough surfaces, and during full-lock turning, as these are classic symptoms of renewed ball joint wear or incorrectly torqued fittings. The steering should feel precise and self-centring without vibration through the wheel, and uneven inner or outer tyre shoulder wear would suggest the geometry was not correctly set after the repair. The 2025 advisory concerning front brake disc pitting and scoring is a typical finding on a vehicle of this age and mileage, and although it was not categorised as a major defect at that time, the condition may have progressed. On inspection, the buyer should measure remaining disc thickness against the manufacturer’s minimum specification, examine the disc surface for lipping and hot spots, and confirm pad material depth. Given that EQC models rely heavily on regenerative braking, the calipers, guide pins, and rear brake components can suffer from corrosion and seizing through underuse, so the handbrake operation and a rolling check for binding or dragging wheels are worthwhile. Additionally, regardless of the relatively healthy MOT record, age-related checks remain relevant: inspect all four tyres for sidewall perishing and manufacturing date, verify 12V auxiliary battery health, confirm recent brake fluid and coolant replacement within manufacturer intervals, and examine the underbody and high-voltage cable routing for any impact damage, as EVs are sensitive to such issues.
