2015 Hymer B — MOT failures & pass rate
295 MOT tests on the 2015 Hymer B are in this dataset, and 91.5% of them passed. All cars of a similar age fail 16.3% of the time, so this is 7.9pp 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 (5.8%) and lighting & signalling (5.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, washers and rbt (sp) — wipers alone was recorded 13 times.
Advisories point at the next bill rather than this one: tyres was flagged on 8.8% of tests without failing them.

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 | 8.8% | 26 |
| 2 | Suspension | 4.1% | 12 |
| 3 | Brakes | 4.1% | 12 |
| 4 | Lighting & signalling | 2.4% | 7 |
| 5 | Steering | 1.7% | 5 |
| 6 | Visibility | 1.7% | 5 |
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 | 160 | 6.9% |
| 30-60k | 121 | 7.4% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2015 B
On a 2015 B, visibility is what the MOT record says goes wrong most — it appeared in 5.8% of tests. Check these areas before you commit.
- Visibility (5.8% 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 (5.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
