2012 Land Rover Defender — MOT failures & pass rate
The 2012 Land Rover Defender passed 81.7% of its 23,330 recorded MOT tests. That is effectively the same as large SUVs of a similar age (17.8% 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 15.3% of tests against 6.3% for the next-worst category.
At component level the recurring items are headlamp aim, position lamp and shock absorbers — headlamp aim alone was recorded 1,509 times.
Condition tracks the odometer closely. Failures run at 9.9% in the 0-30k band and 25.4% in the 150k+ band, a 15.6-point spread — more than double.
Brakes is the most common advisory, noted on 24.4% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2012 Defender
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 15.3% of tests. Start there.
- Lighting & signalling (15.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (6.3% 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 (5.9% 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.
