2017 Alfa Romeo Stelvio — MOT failures & pass rate
The 2017 Alfa Romeo Stelvio passed 89.5% of its 1,151 recorded MOT tests. That is 1.3 percentage points better than mid-size SUVs of a similar age, which fail at 11.8%. Failures cluster in tyres, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.3%) and brakes (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, brake pads and washers — tread depth alone was recorded 37 times.
A 90-120k example is materially riskier than a 0-30k one: 10.5% versus 5.8%.
Advisories point at the next bill rather than this one: brakes was flagged on 25.2% of tests without failing them.
The trend is worsening — 7.7% of tests failed in 2021 against 12.6% 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 | Brakes | 25.2% | 290 |
| 2 | Tyres | 17.7% | 204 |
| 3 | Suspension | 4.9% | 56 |

| 5 | Visibility | 1.7% | 20 |
| 6 | Lighting & signalling | 0.7% | 8 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

What to check before buying a 2017 Stelvio
On a 2017 Stelvio, tyres is what the MOT record says goes wrong most — it appeared in 4.3% of tests. Check these areas before you commit.
- Tyres (4.3% 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.
- Brakes (3.3% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Lighting & signalling (2.6% 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.
