1992 Fiat Hymer — MOT failures & pass rate
Across 253 MOT tests, the 1992 Fiat Hymer recorded a 67.6% pass rate. All cars of a similar age fail 22.7% of the time, so this is 9.7pp worse than the group it competes with. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (24.9%) and brakes (22.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, headlamp aim and headlamp — service brake performance alone was recorded 47 times.
Mileage matters less than usual here: the 1992 Hymer fails 25.9% of the time in the 60-90k band and 22.5% at 150k+, a spread of only 3.4 points.
Suspension is the most common advisory, noted on 44.7% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 32.8% in 2022 to 26.9% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 44.7% | 113 |
| 2 | Brakes | 31.6% | 80 |
| 3 | Emissions & environmental | 28.5% | 72 |
| 4 | Body, structure & corrosion | 26.5% | 67 |
| 5 | Lighting & signalling | 21.7% | 55 |
| 6 | Other defects | 14.2% | 36 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 58 | 25.9% |
| 90-120k | 79 | 34.2% |
| 120-150k | 57 | 36.8% |
| 150k+ | 40 | 22.5% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2022 | 61 | 32.8% |
| 2023 | 56 | 32.1% |
| 2024 | 62 | 35.5% |
| 2025 | 52 | 26.9% |
What to check before buying a 1992 Hymer
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 24.9% of tests. Start there.
- Lighting & signalling (24.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (22.9% 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.
- Body, structure & corrosion (11.1% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
