2015 Alfa Romeo Giulietta — MOT failures & pass rate
Across 18,339 MOT tests, the 2015 Alfa Romeo Giulietta recorded an 81.7% pass rate. Against small family cars of a similar age (15.6% fail rate), the 2015 Giulietta comes out 2.7pp worse. Failures cluster in suspension, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (7.1%) and tyres (7.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, pins and bushes and tread depth — coil spring alone was recorded 695 times.
A 150k+ example is materially riskier than a 0-30k one: 28.2% versus 10.1%.
Split by fuel, diesel examples fail 3.8pp more often than petrol ones (20.4% vs 16.6%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 26.4% of tests without failing them.
The trend is worsening — 14.9% of tests failed in 2021 against 21.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 Giulietta
On a 2015 Giulietta, suspension is what the MOT record says goes wrong most — it appeared in 7.1% of tests. Check these areas before you commit.
- Suspension (7.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Tyres (7.1% 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 (4.4% 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.
