2003 Vauxhall Vectra — MOT failures & pass rate
7,216 MOT tests on the 2003 Vauxhall Vectra are in this dataset, and 69.4% of them passed. Large family cars of a similar age fail 28.1% of the time, so this is 2.5pp worse than the group it competes with. Failures cluster in suspension, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (15.9%) and brakes (14.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, rigid brake pipes and coil spring — headlamp aim alone was recorded 619 times.
A 150k+ example is materially riskier than a 0-30k one: 32.2% versus 12.7%.
Split by fuel, diesel examples fail 1.8pp more often than petrol ones (32.0% vs 30.3%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: brakes was flagged on 41.2% of tests without failing them.
The trend is improving — the fail rate fell from 31.7% in 2021 to 27.7% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2003 Vectra
On a 2003 Vectra, suspension is what the MOT record says goes wrong most — it appeared in 15.9% of tests. Check these areas before you commit.
- Suspension (15.9% 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.
- Brakes (14.4% 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.
- Lighting & signalling (13.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
