2006 Proton Jumbuck — MOT failures & pass rate
1,263 MOT tests on the 2006 Proton Jumbuck are in this dataset, and 70.9% of them passed. That is 1.8 percentage points worse than all cars of a similar age, which fail at 27.3%. Failures cluster in lighting & signalling, suspension and emissions & environmental.
What the MOT record shows
No single area dominates — lighting & signalling (14.1%) and suspension (12.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, catalyst emissions and prescribed areas — component mounting prescribed areas alone was recorded 165 times.
Mileage is the strongest signal on the record: 22.3% of 0-30k cars fail, rising to 36.5% once past 120-150k.
Advisories point at the next bill rather than this one: brakes was flagged on 29.2% 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 |

What to check before buying a 2006 Jumbuck
On a 2006 Jumbuck, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.1% of tests. Check these areas before you commit.
- Lighting & signalling (14.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (12.4% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Emissions & environmental (12.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
