1994 Jeep Wrangler — MOT failures & pass rate
The 1994 Jeep Wrangler passed 75.3% of its 563 recorded MOT tests. Against large SUVs of a similar age (23.7% fail rate), the 1994 Wrangler comes out 1.0pp worse. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 17.1% of all tests — 5.0 points clear of brakes, so it is the first thing to check.
At component level the recurring items are service brake performance, catalyst emissions and headlamp aim — service brake performance alone was recorded 49 times.
Mileage is the strongest signal on the record: 20.0% of 30-60k cars fail, rising to 27.4% once past 120-150k.
Advisories point at the next bill rather than this one: suspension was flagged on 19.5% 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 1994 Wrangler
On a 1994 Wrangler, lighting & signalling is what the MOT record says goes wrong most — it appeared in 17.1% of tests. Check these areas before you commit.
- Lighting & signalling (17.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (12.1% 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.
- Suspension (7.1% 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.
