2017 Toyota Gt86 — MOT failures & pass rate
3,377 MOT tests on the 2017 Toyota Gt86 are in this dataset, and 92.4% of them passed. That is 2.2 percentage points better than coupes & convertibles of a similar age, which fail at 9.8%. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.2%) and visibility (3.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, catalyst emissions and tread depth — wipers alone was recorded 99 times.
Mileage is the strongest signal on the record: 4.3% of 0-30k cars fail, rising to 20.0% once past 90-120k — 4.6× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 20.9% of tests without failing them.
The trend is worsening — 5.7% of tests failed in 2021 against 9.0% 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.

| 30-60k | 1,523 | 9.0% |
| 60-90k | 352 | 12.2% |
| 90-120k | 55 | 20.0% |
Failure rate by age
Trend over time

What to check before buying a 2017 Gt86
On a 2017 Gt86, tyres is what the MOT record says goes wrong most — it appeared in 3.2% of tests. Check these areas before you commit.
- Tyres (3.2% 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 (3.1% 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.
- Lighting & signalling (2.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
