2022 Mercedes-Benz EQA 300 AMG Line 4MATIC Electricity · LG22 KBK

The mechanical story of this EQA 300 AMG Line is one dominated entirely by tyre-related issues, with the underlying chassis, braking, suspension, and drivetrain components recording a clean bill of health across all available tests. The most recent examination on 26 March 2026 recorded a straightforward pass with only a minor defect noted against the front wiper blade and a single advisory for a nail embedded in the nearside front inner tyre. Looking at the broader trajectory, this is not a vehicle exhibiting deteriorating roadworthiness or chronic failure patterns; the only recorded failure, dated 10 March 2025, was directly linked to an offside rear tyre with a cut exposing ply or cord, an item that was clearly rectified within the two days before the subsequent pass on 12 March 2025. The early 2025 test also flagged both front tyres as worn close to the legal limit on their edges, suggesting that prior to replacement, the original-fitment rubber had been worked hard across the front axle, but there has been no recurrence of edge wear or structural tyre concern in the most recent inspection. With only 21,014 miles accumulated across the vehicle's roughly four-year lifespan, annual mileage works out at around 5,254 miles, which is considerably below average for a premium SUV of this age. This lighter usage pattern typically translates into extended longevity for friction components such as brake discs, pads, and the electric drivetrain, since wear is largely dictated by mileage rather than calendar age on an EV-derived platform. However, the lower accumulation rate can also mean longer intervals between services and longer standing periods, which can have subtle effects on the 12-volt auxiliary battery, tyre sidewall integrity through prolonged inflation stress, and brake disc surface corrosion if the vehicle is left stationary for extended periods. The relatively even spread of MOT dates without any multi-year gaps suggests the car has remained in active use throughout its life rather than being laid up, which is reassuring from a mechanical perspective. For a prospective buyer, the immediate priority should be a thorough inspection of all four tyres, paying particular attention to tread depth across the full width of the front pair, as the historical advisories specifically noted edge wear, a symptom often associated with incorrect camber geometry, aggressive cornering, or misalignment following kerb impact. On a test drive, listen for any uneven road noise from the front axle that might indicate asymmetric wear persisting after the 2025 tyre change, and feel for any pulling to one side under braking or steady-state driving that could suggest the alignment was not corrected when the tyres were replaced. Inspect the sidewalls carefully for any cracking, bulging, or embedded debris, as the advisory for a nail in the nearside front tyre in early 2026 indicates the vehicle is being used in environments where pick-up is a recurring risk. Beyond the tyres, the test drive should focus on the specific components likely to suffer on a low-mileage EV-based SUV, including the brake system, where light use can lead to disc corrosion and subsequent judder under braking; a series of moderate stops from around 40 mph should produce smooth, even pedal feel without vibration through the steering wheel. Pay attention to suspension compliance over broken surfaces, listening for any clonks or knocks from the front strut assemblies or anti-roll bar linkages that might have been stressed despite the low mileage. Finally, confirm the operation of the windscreen wiper system, as a defective wiper blade was flagged in the most recent test, and verify the proper functioning of the regenerative braking system and any brake hold features, as these can mask conventional brake wear on lightly used vehicles.
