2023 Mercedes-Benz EQC 400 AMG Line 4MATIC Electric · RF72 OSN

A young, premium EV with a relatively sparse testing record, but the lone advisory logged at the January 2026 test is already pointing toward uneven rear axle geometry or aggressive cornering wear, with both inner rear tyres flagged as worn close to the legal limit and feathered on the edge. The fact that this is the only MOT entry on file means there is limited longitudinal evidence to draw on, yet what is recorded does not read as a clean bill of health, because rear inner-edge wear on a four-wheel-drive EV with this much road use typically signals either a tracking issue, worn rear suspension bushes, or persistent hard cornering loading on the driven axle. As this is a 2023 model, the absence of any earlier test outcome leaves the buyer without the usual trend to assess whether the situation is stable or deteriorating, so a physical inspection becomes especially important. The mileage profile is the most striking element of this file. At roughly 66,186 miles against a three-year registration, the EQC is averaging somewhere in the region of 22,000 miles per year, which is more than double a typical annual mileage for a UK vehicle of this age and class. That level of accumulation will have pushed the rotating masses, regenerative braking components and suspension well beyond what a low-mileage example would experience, increasing the likelihood of premature wear on items such as the rear bush assemblies, control arms and hub bearings. EVs are mechanically simpler than their combustion counterparts, but they still suffer disproportionately from high-mileage ride and refinement complaints, particularly around bush compliance and tyre wear on the driven corners, which aligns neatly with the advisory already recorded. For a prospective buyer, the priority on a physical inspection should be a close look at the rear tyres themselves, checking both the inner and outer tread depths with a gauge and looking for feathering on the inner blocks by running a hand across the tread surface, which would confirm uneven wear rather than a one-off scrub. The rear suspension should be exercised firmly by hand at each corner if access allows, with attention to the trailing arm and spring seat bushes for any play or cracking, while a road test should focus on any clonking or thumping over uneven surfaces, vague or wandering steering, and whether the car tracks straight without pulling under acceleration, as high-mileage EVs can mask geometry issues through software intervention. The brake system, despite regenerative duties, still requires checking for binding rear calipers and uneven disc wear, particularly if the mechanical handbrake mechanism has been underused, which can lead to corrosion on the inner face of the rear discs. Beyond the specific advisory, it is worth pressing the dealer or seller on the provenance of the tyres currently fitted, as the rear pair may already have been replaced since the test, and verifying whether a four-wheel alignment printout is available to evidence the geometry has been corrected. Given the heavy annual mileage, a compression check of the high-voltage battery state of health via diagnostic equipment is strongly advised, as capacity degradation accelerates with high use, particularly if the vehicle has been regularly rapid-charged. Finally, the omission of any earlier MOT results should prompt questions about why the vehicle only entered the testing cycle at this stage, and whether the recorded mileage is fully supported by service history documentation to avoid any clocking concerns given the unusually high accumulation for the age of the car.
