2020 Alfa Romeo Stelvio — MOT failures & pass rate
1,014 MOT tests on the 2020 Alfa Romeo Stelvio are in this dataset, and 92.1% of them passed. Mid-size SUVs of a similar age fail at 8.8%, so the 2020 Stelvio sits squarely on the average. Failures cluster in brakes, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — brakes (3.1%) and tyres (2.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake pads, tread depth and malfunction indicator lamp — brake pads alone was recorded 35 times.
Mileage matters less than usual here: the 2020 Stelvio fails 7.3% of the time in the 0-30k band and 4.8% at 60-90k, a spread of only 2.5 points.
Advisories point at the next bill rather than this one: brakes was flagged on 21.8% of tests without failing them.

What to check before buying a 2020 Stelvio
On a 2020 Stelvio, brakes is what the MOT record says goes wrong most — it appeared in 3.1% of tests. Check these areas before you commit.
- Brakes (3.1% 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.
- Tyres (2.8% 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 (1.7% 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.
