2015 Toyota Gt86 — MOT failures & pass rate
The 2015 Toyota Gt86 passed 89.6% of its 3,954 recorded MOT tests. That is 1.5 percentage points better than coupes & convertibles of a similar age, which fail at 11.9%. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (4.9%) and lighting & signalling (3.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, wipers and catalyst emissions — tread depth alone was recorded 122 times.
A 90-120k example is materially riskier than a 0-30k one: 12.6% versus 6.2%.
Advisories point at the next bill rather than this one: tyres was flagged on 18.9% of tests without failing them.
The trend is worsening — 8.4% of tests failed in 2021 against 11.4% 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 |

| 5 | Other defects | 3.4% | 136 |
| 6 | Lighting & signalling | 2.8% | 112 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 30-60k | 2,034 | 10.8% |
| 60-90k | 956 | 12.6% |
| 90-120k | 183 | 12.6% |
Failure rate by age

What to check before buying a 2015 Gt86
On a 2015 Gt86, tyres is what the MOT record says goes wrong most — it appeared in 4.9% of tests. Check these areas before you commit.
- Tyres (4.9% 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.
- Lighting & signalling (3.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (3.0% 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.
