Mercedes-Benz Eqe 300 MOT pass rate & common failures
Across 4 model years and 2,585 tests, the Mercedes-Benz Eqe 300 passes its MOT 95.9% of the time. All cars of a similar age fail 6.0% of the time, so this is 1.9pp better than the group it competes with. Its most common failure areas are tyres, visibility and body, structure & corrosion.
What the MOT record shows
Tyres dominates the failure mix at 4.0% of all tests — 3.7 points clear of visibility, so it is the first thing to check.
At component level the recurring items are tread depth, tyre pressure monitoring system and brake pads — tread depth alone was recorded 28 times.
Mileage matters less than usual here: the Eqe 300 fails 3.5% of the time in the 0-30k band and 0.0% at 90-120k, a spread of only 3.5 points.
Advisories point at the next bill rather than this one: tyres was flagged on 12.3% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 12.3% | 319 |
| 2 | Other defects | 2.4% | 63 |
| 3 | Brakes | 1.7% | 44 |

| 5 | Visibility | 0.4% | 10 |
| 6 | Road wheels | 0.1% | 3 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 1,128 | 3.5% |
| 30-60k | 1,091 | 4.1% |
| 60-90k | 321 | 6.2% |
| 90-120k | 42 | 0.0% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2025 | 1,762 | 4.7% |
What to check before buying a Mercedes-Benz Eqe 300
- Tyres (4.0% 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 (0.3% 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.
- Body, structure & corrosion (0.1% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
