2006 Jeep Wrangler — MOT failures & pass rate
The 2006 Jeep Wrangler passed 82.8% of its 395 recorded MOT tests. That is 7.5 percentage points better than large SUVs of a similar age, which fail at 24.7%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 14.9% of tests against 5.6% for the next-worst category.
At component level the recurring items are headlamp aim, service brake performance and wipers — headlamp aim alone was recorded 33 times.
Mileage matters less than usual here: the 2006 Wrangler fails 14.7% of the time in the 0-30k band and 12.9% at 120-150k, a spread of only 1.8 points.
Suspension is the most common advisory, noted on 24.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 9.1% of tests failed in 2021 against 18.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2006 Wrangler
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.9% of tests. Start there.
- Lighting & signalling (14.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.6% 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.
- Brakes (4.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
