2022 Mercedes-Benz EQC 400 AMG Line Premium + 4M Electric · FV71 UPO

With only two MOT tests on record and both resulting in clean passes without advisories or defects, this 2022 Mercedes-Benz EQC 400 presents an encouraging but immature roadworthiness profile. The most recent examination on 5 November 2025 returned a pass with no defects recorded, mirroring the identical outcome from the first test on 11 November 2024. While the absence of advisories is reassuring for a prospective buyer, the limited testing history means there is insufficient data to identify any emerging wear patterns, and the clean record reflects only two annual snapshots rather than a long-term mechanical trend. Given the EQC's relative newness as Mercedes' inaugural bespoke EV platform, this is largely expected, but buyers should not interpret the blank slate as confirmation of long-term durability. The recorded mileage of 86,349 against an age of approximately four years translates to an annual accumulation of around 21,587 miles, which is notably high for any vehicle, and particularly so for an electric SUV of this class. This usage intensity carries specific mechanical implications: although the absence of an internal combustion engine removes concerns over oil degradation, timing components, and exhaust corrosion, the drivetrain and ancillary systems will have absorbed significantly more thermal cycling and load exposure than a lower-mileage example. The single-year gap between tests shows continuous service, with mileage progression from the 2024 test to the 2025 test requiring verification through the V5 and service records. High electric mileage typically accelerates wear on suspension components, brake hardware (despite regenerative braking reducing pad consumption, the friction brakes can suffer from corrosion due to infrequent use), tyres, and underbody hardware exposed to road grit and moisture. For a test drive, attention should focus on the suspension geometry and steering response, as high-mileage EVs frequently show early wear in control arm bushes and anti-roll bar linkages, which manifests as a vague or wandering feel at speed and audible knocking or clonking over broken surfaces. Listen for any humming or rotational drone from the driveline that could indicate motor mount degradation or bearing wear, and test the regenerative braking system for smooth, consistent deceleration rather than abrupt interruptions. Given that the friction brakes may have seen limited use, perform several firm stops from higher speeds to confirm the callipers are releasing correctly without binding, and inspect the discs visually for any surface rust pitting that could lead to judder under heavy braking. The tyres should be examined for even shoulder wear, as consistent wear patterns are particularly important on a heavy dual-motor 4Matic vehicle to confirm correct alignment and absence of suspension geometry deviation. Because no specific components have been flagged in the MOT history, there is no targeted defect list to cross-reference, which means the buyer must rely heavily on a comprehensive pre-purchase inspection. A high-voltage battery state-of-health report from a Mercedes specialist or independent EV diagnostics provider is essential at this mileage, as degradation directly impacts range and resale value far more than any mechanical wear item. Underbody inspection should look for corrosion on subframe mounting points, brake line integrity, and any evidence of accident damage that may have compromised the high-voltage cabling routing. Finally, verify that all driver-assistance systems, including the radar and camera sensors behind the windscreen and badges, are functioning correctly, as calibration issues are not recorded under MOT but can be costly to rectify and are worth confirming before purchase.
