2003 Vauxhall Corsa — MOT failures & pass rate
Across 69,982 MOT tests, the 2003 Vauxhall Corsa recorded a 67.9% pass rate. Against superminis of a similar age (29.3% fail rate), the 2003 Corsa comes out 2.7pp worse. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (16.1%) and lighting & signalling (15.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are joints, headlamp aim and coil spring — joints alone was recorded 5,940 times.
Condition tracks the odometer closely. Failures run at 24.4% in the 0-30k band and 34.5% in the 150k+ band, a 10.1-point spread.
The petrol cars hold up better: 32.0% fail against 34.2% for diesel, a 2.3-point gap across 69,982 tests.
Suspension is the most common advisory, noted on 32.0% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 32.8% in 2021 to 30.5% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2003 Corsa
The failure pattern for this year is specific enough to inspect against: suspension accounted for 16.1% of tests. Start there.
- Suspension (16.1% 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.
- Lighting & signalling (15.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (13.5% 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.
