1993 Jeep Wrangler — MOT failures & pass rate
Across 459 MOT tests, the 1993 Jeep Wrangler recorded a 73.4% pass rate. That is 3.0 percentage points worse than large SUVs of a similar age, which fail at 23.6%. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 19.6% of tests against 12.8% for the next-worst category.
At component level the recurring items are catalyst emissions, position lamp and service brake performance — catalyst emissions alone was recorded 40 times.
Mileage is the strongest signal on the record: 28.0% of 30-60k cars fail, rising to 23.1% once past 120-150k.
Brakes is the most common advisory, noted on 23.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 23.5% of tests failed in 2021 against 29.1% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 23.5% | 108 |
| 2 | Body, structure & corrosion | 16.8% | 77 |
| 3 | Suspension | 16.6% | 76 |
| 4 | Steering | 13.3% | 61 |
| 5 | Lighting & signalling | 10.9% | 50 |
| 6 | Emissions & environmental | 9.8% | 45 |
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 | 50 | 28.0% |
| 60-90k | 182 | 23.6% |
| 90-120k | 152 | 32.2% |
| 120-150k | 52 | 23.1% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 98 | 23.5% |
| 2022 | 91 | 22.0% |

What to check before buying a 1993 Wrangler
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 19.6% of tests. Start there.
- Lighting & signalling (19.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (12.8% 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 (9.6% 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.
