Mercedes-Benz Eqc 400 4Matic MOT pass rate & common failures
Across 5 model years and 11,251 tests, the Mercedes-Benz Eqc 400 4Matic passes its MOT 89.7% of the time. All cars of a similar age fail 8.9% of the time, so this is 1.4pp worse than the group it competes with. Its most common failure areas are tyres, visibility and suspension.
What the MOT record shows
Tyres dominates the failure mix at 8.1% of all tests — 6.6 points clear of visibility, so it is the first thing to check.
At component level the recurring items are ball joint, headlamp aim and wipers — ball joint alone was recorded 171 times.
Condition tracks the odometer closely. Failures run at 8.5% in the 0-30k band and 12.9% in the 90-120k band, a 4.4-point spread.
Advisories point at the next bill rather than this one: tyres was flagged on 29.7% of tests without failing them.
The trend is worsening — 5.3% of tests failed in 2022 against 10.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a Mercedes-Benz Eqc 400 4Matic
- Tyres (8.1% 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.
- Visibility (1.5% 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.
- Suspension (1.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
