2021 Mercedes-Benz EQC 400 AMG Line Premium + 4M Electric · GY71 XTJ

The vehicle’s most recent MOT test on 2025-11-20 confirms it remains roadworthy, with no defects recorded despite a near-miss failure on the preceding day at identical mileage. This suggests the tester initially overlooked a minor but correctable issue—likely a procedural oversight rather than a recurring mechanical flaw. The absence of advisories or repeated failures over the past two tests indicates no obvious pattern of neglect or impending failure in critical systems. However, the double-testing in November 2025 raises a small red flag: either the tester was unusually thorough or the vehicle narrowly avoided a passable but borderline condition. For a buyer, this warrants scrutiny of components that frequently cause borderline failures, such as suspension alignment or minor brake wear. The mileage progression of 56,815 miles at the latest test reflects a steady, if not aggressive, usage pattern—approximately 11,363 miles annually over five years. This is within the expected range for a premium electric vehicle of this age, though it implies higher-than-average wear on high-friction parts like tyres, brake pads, and suspension bushes. The gap between tests—just over a year—aligns with the standard MOT interval, with no extended periods of inactivity that might suggest prolonged storage-related issues. There is no evidence of mileage tampering, as the figures increment logically between tests, but the lack of service records means potential hidden wear cannot be confirmed. Given the clean MOT history, the primary focus for an in-person inspection should centre on the suspension and braking systems. The double-testing in November 2025 hints at possible borderline conditions in rear wheel bearings or binding calipers, which are common causes of near-failures. Check for uneven tyre wear, which could indicate misaligned wheels or worn suspension bushes. The absence of advisories does not rule out corrosion in wheel arches or subframe areas, particularly given the vehicle’s age and typical UK environmental exposure. Verify the integrity of the high-voltage battery cooling system and any software updates, as electric vehicles often require specialised maintenance beyond conventional MOT checks. Finally, inspect the exhaust system for leaks or damage, as emissions-related failures are occasionally overlooked in otherwise clean records.
