2020 Fiat Hymer — MOT failures & pass rate
Across 271 MOT tests, the 2020 Fiat Hymer recorded a 95.2% pass rate. Against all cars of a similar age (9.3% fail rate), the 2020 Hymer comes out 4.5pp better. Failures cluster in visibility, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — visibility (4.8%) and lighting & signalling (3.7%) 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 malfunction indicator lamp — wipers alone was recorded 14 times.

What to check before buying a 2020 Hymer
On a 2020 Hymer, visibility is what the MOT record says goes wrong most — it appeared in 4.8% of tests. Check these areas before you commit.
- Visibility (4.8% 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.
- Lighting & signalling (3.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (1.1% 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.
