2007 Chrysler Jeep Wrangler — MOT failures & pass rate
Across 328 MOT tests, the 2007 Chrysler Jeep Wrangler recorded a 72.9% pass rate. That is effectively the same as all cars of a similar age (26.9% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 19.8% of tests against 16.2% for the next-worst category.
At component level the recurring items are ball joint, headlamp aim and rbt (sp) — ball joint alone was recorded 29 times.
A 150k+ example is materially riskier than a 30-60k one: 31.3% versus 18.2%.
Brakes is the most common advisory, noted on 25.0% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 26.4% in 2021 to 22.4% in 2025, as the worst-kept examples leave the fleet.

| 6 | Lighting & signalling | 8.8% | 29 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

| 30-60k | 66 | 18.2% |
| 60-90k | 112 | 29.5% |

What to check before buying a 2007 Wrangler
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 19.8% of tests. Start there.
- Lighting & signalling (19.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (16.2% 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.
- Suspension (9.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
