2019 Alfa Romeo Giulietta — MOT failures & pass rate
Across 2,314 MOT tests, the 2019 Alfa Romeo Giulietta recorded an 88.9% pass rate. Small family cars of a similar age fail 9.7% of the time, so this is 1.4pp worse than the group it competes with. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (5.8%) and visibility (3.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are washers, tread depth and headlamp aim — washers alone was recorded 70 times.
Condition tracks the odometer closely. Failures run at 8.1% in the 0-30k band and 15.7% in the 60-90k band, a 7.5-point spread.
Split by fuel, diesel examples fail 3.1pp more often than petrol ones (12.9% vs 9.8%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 24.0% of tests without failing them.
The trend is worsening — 8.6% of tests failed in 2022 against 15.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 Giulietta
On a 2019 Giulietta, tyres is what the MOT record says goes wrong most — it appeared in 5.8% of tests. Check these areas before you commit.
- Tyres (5.8% 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.
- Visibility (3.3% 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 (2.4% 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.
