2005 SEAT Ibiza — MOT failures & pass rate
The 2005 SEAT Ibiza passed 69.2% of its 13,797 recorded MOT tests. Superminis of a similar age fail 28.8% of the time, so this is 2.0pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (16.8%) and suspension (14.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, stop lamp and position lamp — headlamp aim alone was recorded 939 times.
A 150k+ example is materially riskier than a 0-30k one: 32.6% versus 16.8%.
Split by fuel, petrol examples fail 2.0pp more often than diesel ones (31.2% vs 29.2%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: suspension was flagged on 30.6% of tests without failing them.
The trend is improving — the fail rate fell from 31.7% in 2021 to 30.2% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2005 Ibiza
On a 2005 Ibiza, lighting & signalling is what the MOT record says goes wrong most — it appeared in 16.8% of tests. Check these areas before you commit.
- Lighting & signalling (16.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (14.6% 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 (11.2% 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.
