2016 Mercedes-Benz Gt — MOT failures & pass rate
The 2016 Mercedes-Benz Gt passed 93.3% of its 1,541 recorded MOT tests. All cars of a similar age fail 14.5% of the time, so this is 7.7pp better than the group it competes with. Failures cluster in tyres, other defects and emissions & environmental.
What the MOT record shows
One area stands out: tyres, recorded in 4.7% of tests against 1.2% for the next-worst category.
At component level the recurring items are tread depth, registration plates and catalyst emissions — tread depth alone was recorded 39 times.
Mileage is the strongest signal on the record: 6.0% of 0-30k cars fail, rising to 11.4% once past 60-90k.
Tyres is the most common advisory, noted on 14.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 5.6% of tests failed in 2021 against 8.6% in 2025, the usual pattern as a fleet ages.

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 | 14.3% | 220 |
| 2 | Brakes | 3.3% | 51 |

| 5 | Emissions & environmental | 1.1% | 17 |
| 6 | Suspension | 0.6% | 9 |
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 | 1,041 | 6.0% |
| 30-60k | 463 | 8.2% |
| 60-90k | 35 | 11.4% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2016 Gt
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.7% of tests. Start there.
- Tyres (4.7% 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.
- Other defects (1.2% of tests): Miscellaneous items not in the main categories. Typical repair: varies.
- Emissions & environmental (0.9% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
