2018 Fiat Adria — MOT failures & pass rate
Across 829 MOT tests, the 2018 Fiat Adria recorded a 95.8% pass rate. All cars of a similar age fail 11.1% of the time, so this is 6.8pp better than the group it competes with. Failures cluster in lighting & signalling, visibility and seat belts & restraints.
What the MOT record shows
No single area dominates — lighting & signalling (3.4%) and visibility (2.8%) 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 rear fog lamp — wipers alone was recorded 29 times.

What to check before buying a 2018 Adria
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 3.4% of tests. Start there.
- Lighting & signalling (3.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.8% 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 (0.6% 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.
