2005 Jeep Wrangler — MOT failures & pass rate
The 2005 Jeep Wrangler passed 83.2% of its 345 recorded MOT tests. Large SUVs of a similar age fail 25.1% of the time, so this is 8.3pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 13.9% of all tests — 8.1 points clear of brakes, so it is the first thing to check.
At component level the recurring items are headlamp aim, rear fog lamp and wipers — headlamp aim alone was recorded 23 times.
Mileage is the strongest signal on the record: 13.1% of 30-60k cars fail, rising to 21.6% once past 90-120k.
Advisories point at the next bill rather than this one: suspension was flagged on 27.3% of tests without failing them.
The trend is improving — the fail rate fell from 20.4% in 2021 to 11.3% in 2025, as the worst-kept examples leave the fleet.

| 60-90k | 144 | 16.7% |
| 90-120k | 74 | 21.6% |
Failure rate by age

What to check before buying a 2005 Wrangler
On a 2005 Wrangler, lighting & signalling is what the MOT record says goes wrong most — it appeared in 13.9% of tests. Check these areas before you commit.
- Lighting & signalling (13.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (5.8% 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.
- Suspension (4.9% 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.
