1994 Land Rover Defender — MOT failures & pass rate
14,590 MOT tests on the 1994 Land Rover Defender are in this dataset, and 74.2% of them passed. Large SUVs of a similar age fail 23.7% of the time, so this is 2.1pp worse than the group it competes with. Failures cluster in lighting & signalling, body, structure & corrosion and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 19.0% of tests against 10.9% for the next-worst category.
At component level the recurring items are chassis condition, position lamp and headlamp aim — chassis condition alone was recorded 1,035 times.
Condition tracks the odometer closely. Failures run at 21.1% in the 0-30k band and 27.2% in the 150k+ band, a 6.1-point spread.
Emissions & environmental is the most common advisory, noted on 32.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 27.6% in 2021 to 24.6% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 1994 Defender
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 19.0% of tests. Start there.
- Lighting & signalling (19.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (10.9% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Suspension (10.1% 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.
