2017 Fiat Hymer — MOT failures & pass rate
Across 783 MOT tests, the 2017 Fiat Hymer recorded a 93.9% pass rate. All cars of a similar age fail 12.7% of the time, so this is 6.6pp better than the group it competes with. Failures cluster in visibility, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — visibility (3.3%) and lighting & signalling (2.9%) 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 service brake performance — wipers alone was recorded 35 times.
The trend is worsening — 3.1% of tests failed in 2021 against 8.6% in 2025, the usual pattern as a fleet ages.

|---|---|---|
| 0-30k | 662 | 5.7% |
| 30-60k | 119 | 7.6% |

What to check before buying a 2017 Hymer
On a 2017 Hymer, visibility is what the MOT record says goes wrong most — it appeared in 3.3% of tests. Check these areas before you commit.
- 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 (2.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (1.9% 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.
