2019 Alfa Romeo Giulia — MOT failures & pass rate
Across 6,518 MOT tests, the 2019 Alfa Romeo Giulia recorded a 90.3% pass rate. That is effectively the same as executive cars of a similar age (10.3% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (5.1%) and lighting & signalling (3.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and brake pads — headlamp aim alone was recorded 217 times.
Mileage is the strongest signal on the record: 7.2% of 0-30k cars fail, rising to 13.7% once past 90-120k.
The petrol cars hold up better: 9.1% fail against 12.4% for diesel, a 3.2-point gap across 6,518 tests.
Tyres is the most common advisory, noted on 18.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.5% of tests failed in 2021 against 10.4% 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.

| 5 | Visibility | 1.6% | 102 |
| 6 | Road wheels | 0.4% | 29 |
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 | 3,003 | 7.2% |
| 30-60k | 2,894 | 11.6% |

What to check before buying a 2019 Giulia
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.1% of tests. Start there.
- Tyres (5.1% 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 (3.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
