Hymer B MOT pass rate & common failures
The Hymer B appears in 1,964 MOT tests spanning model years 2002–2022, and 89.7% of them passed. Against all cars of a similar age (13.4% fail rate), the B comes out 3.0pp better. Its most common failure areas are lighting & signalling, brakes and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (6.4%) and brakes (4.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, wipers and rbt (sp) — headlamp aim alone was recorded 68 times.
Mileage is the strongest signal on the record: 10.1% of 0-30k cars fail, rising to 22.2% once past 60-90k — 2.2× the risk.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 6.6% | 130 |
| 2 | Brakes | 4.8% | 94 |
| 3 | Lighting & signalling | 2.8% | 54 |

| 5 | Suspension | 1.4% | 27 |
| 6 | Other defects | 1.1% | 21 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

| 0-30k | 1,449 | 10.1% |
| 30-60k | 477 | 10.3% |
| 60-90k | 36 | 22.2% |
Failure rate by age

What to check before buying a Hymer B
- Lighting & signalling (6.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (4.1% 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.
- Visibility (3.4% 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.
