Fiat Hymer MOT pass rate & common failures
Across 38 model years and 8,063 tests, the Fiat Hymer passes its MOT 82.6% of the time. All cars of a similar age fail 20.3% of the time, so this is 2.8pp better than the group it competes with. Its most common failure areas are lighting & signalling, brakes and visibility.
What the MOT record shows
Lighting & signalling dominates the failure mix at 13.2% of all tests — 6.2 points clear of brakes, so it is the first thing to check.
At component level the recurring items are headlamp aim, wipers and service brake performance — headlamp aim alone was recorded 528 times.
A 150k+ example is materially riskier than a 0-30k one: 32.4% versus 6.5%.
Advisories point at the next bill rather than this one: suspension was flagged on 18.0% of tests without failing them.

What to check before buying a Fiat Hymer
- Lighting & signalling (13.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (7.0% 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.
- Visibility (5.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
