2020 Mercedes-Benz Eqc 400 4Matic — MOT failures & pass rate
Across 5,217 MOT tests, the 2020 Mercedes-Benz Eqc 400 4Matic recorded an 89.9% pass rate. All cars of a similar age fail at 9.4%, so the 2020 Eqc 400 4Matic sits squarely on the average. Failures cluster in tyres, suspension and visibility.
What the MOT record shows
Tyres dominates the failure mix at 7.5% of all tests — 5.6 points clear of suspension, so it is the first thing to check.
At component level the recurring items are ball joint, registration plates and headlamp aim — ball joint alone was recorded 97 times.
Mileage matters less than usual here: the 2020 Eqc 400 4Matic fails 7.7% of the time in the 0-30k band and 7.3% at 90-120k, a spread of only 0.4 points.
Advisories point at the next bill rather than this one: tyres was flagged on 29.8% of tests without failing them.
The trend is worsening — 9.3% of tests failed in 2023 against 11.7% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2020 Eqc 400 4Matic
On a 2020 Eqc 400 4Matic, tyres is what the MOT record says goes wrong most — it appeared in 7.5% of tests. Check these areas before you commit.
- Tyres (7.5% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Suspension (1.9% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Visibility (1.2% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
