2003 Land Rover Defender — MOT failures & pass rate
The 2003 Land Rover Defender passed 75.4% of its 27,528 recorded MOT tests. That is effectively the same as large SUVs of a similar age (25.3% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 14.1% of tests against 9.3% for the next-worst category.
At component level the recurring items are shock absorbers, headlamp aim and washers — shock absorbers alone was recorded 1,496 times.
Mileage is the strongest signal on the record: 13.6% of 0-30k cars fail, rising to 26.3% once past 150k.
Suspension is the most common advisory, noted on 29.2% 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 2003 Defender
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.1% of tests. Start there.
- Lighting & signalling (14.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.3% 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 (8.7% 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.
