2003 Vauxhall Frontera — MOT failures & pass rate
1,292 MOT tests on the 2003 Vauxhall Frontera are in this dataset, and 71.7% of them passed. Mid-size SUVs of a similar age fail at 28.1%, so the 2003 Frontera sits squarely on the average. Failures cluster in brakes, body, structure & corrosion and lighting & signalling.
What the MOT record shows
No single area dominates — brakes (15.0%) and body, structure & corrosion (14.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rigid brake pipes, service brake performance and joints — rigid brake pipes alone was recorded 123 times.
A 150k+ example is materially riskier than a 30-60k one: 28.6% versus 23.3%.
Advisories point at the next bill rather than this one: suspension was flagged on 46.3% of tests without failing them.
The trend is improving — the fail rate fell from 28.9% in 2021 to 24.2% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2003 Frontera
On a 2003 Frontera, brakes is what the MOT record says goes wrong most — it appeared in 15.0% of tests. Check these areas before you commit.
- Brakes (15.0% 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.
- Body, structure & corrosion (14.7% 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+.
- Lighting & signalling (11.2% 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.
