2021 Mercedes-Benz EQC 400 AMG Line 4MATIC Electric · LC71 RBX

An above-average annual mileage of roughly 13,673 miles per year on a five-year-old Mercedes-Benz EQC 400 AMG Line 4MATIC places this electric SUV in a higher-than-average usage bracket, and the single advisory issued at the most recent test on 5 May 2026 suggests that wear-related items are beginning to surface as the vehicle accumulates distance. The recorded DVSA history is sparse, with only two MOT tests documented, both of which resulted in pass certificates; the 2025 test was entirely free of advisories or defects, while the 2026 test flagged only front brake pads as wearing thin. There is no pattern of recurring advisories, structural corrosion, suspension component defects, or emissions-related failures present in the record, which presents a roadworthiness profile consistent with a vehicle that has not yet developed chronic mechanical concerns at the point of test. However, the limited number of recorded tests means the history alone cannot fully characterise the car's long-term mechanical condition, particularly given that electric vehicles first become subject to MOT testing once they reach three years of age. With the first registration in 2021 and an MOT record commencing only at the four-year mark, the early life of this EQC is not covered by DVSA testing data, and the mileage progression between the two recorded tests shows a substantial accumulation of approximately 23,000 miles in the twelve months leading up to May 2026. This annual figure is considerably higher than the five-year average suggests and indicates the vehicle is being driven intensively rather than used lightly or stored for extended periods. For an electric SUV of this weight and specification, higher annual mileage typically translates to accelerated wear on the friction braking system, as regenerative braking reduces but does not eliminate reliance on the conventional discs and pads during higher-speed deceleration and holding manoeuvres. Tyre wear on all four corners should also be anticipated, particularly on the driven axles given the 4MATIC configuration. Given the advisory issued at the 2026 test regarding thin front brake pads, a prospective buyer should pay close attention to the braking performance during a test drive, listening for any grinding, squealing, or scraping noises on light application that would indicate the pads have worn beyond the advisory threshold since the test. The pedal feel should be firm and progressive without excessive travel, and any judder through the steering wheel or brake pedal under firm stopping suggests potential disc warping, which is a common consequence of repeated heavy braking on high-mileage vehicles. The brake discs themselves should be inspected for lipping around the outer edge and for any visible scoring or corrosion pitting, particularly on the inner face which is not always visible without removing the wheel. As the front pads wear, uneven wear patterns can develop if a caliper is binding or a slider mechanism has seized, so it is worth asking whether the calipers have been cleaned and re-greased as part of routine servicing. Although the MOT record does not flag any suspension, steering, or underbody corrosion issues, the higher-than-average mileage warrants a careful inspection of the front and rear suspension components, including the control arm bushes, anti-roll bar links, and coil springs, all of which are subject to accelerated wear under intensive use. On a test drive, listen for any clonks, knocks, or creaks from the front end when traversing speed bumps or uneven surfaces, and pay attention to any vagueness or delay in the steering response that could indicate worn tie rod ends or drop links. The tyres should be checked for even wear across the tread, as uneven shoulder wear can point to misalignment issues, while central wear may indicate over-inflation. Finally, although the EQC is an electric vehicle and therefore exempt from exhaust emissions testing, the integrity of the high-voltage system, charging cable, and 12-volt auxiliary battery should be confirmed, as a failing auxiliary battery is one of the more common causes of non-start conditions and electrical faults on Mercedes-Benz EQ models.
