2017 Fiat Adria — MOT failures & pass rate
Across 897 MOT tests, the 2017 Fiat Adria recorded a 93.1% pass rate. Against all cars of a similar age (12.7% fail rate), the 2017 Adria comes out 5.7pp better. Failures cluster in lighting & signalling, visibility and seat belts & restraints.
What the MOT record shows
No single area dominates — lighting & signalling (3.9%) and visibility (2.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and srs malfunction indicator lamp — wipers alone was recorded 26 times.
Advisories point at the next bill rather than this one: tyres was flagged on 10.5% of tests without failing them.
The trend is improving — the fail rate fell from 8.2% in 2021 to 6.7% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2017 Adria
On a 2017 Adria, lighting & signalling is what the MOT record says goes wrong most — it appeared in 3.9% of tests. Check these areas before you commit.
- Lighting & signalling (3.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.2% 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.
- Seat belts & restraints (1.6% of tests): Belt damage or faulty pretensioners — usually straightforward but safety-critical. Typical repair: £50–£300.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
