1999 Vauxhall Frontera — MOT failures & pass rate
539 MOT tests on the 1999 Vauxhall Frontera are in this dataset, and 74.0% of them passed. Mid-size SUVs of a similar age fail 28.3% of the time, so this is 2.4pp better than the group it competes with. Failures cluster in brakes, body, structure & corrosion and suspension.
What the MOT record shows
No single area dominates — brakes (13.2%) and body, structure & corrosion (12.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rigid brake pipes, prescribed areas and joints — rigid brake pipes alone was recorded 67 times.
Mileage is the strongest signal on the record: 17.8% of 0-30k cars fail, rising to 30.4% once past 150k.
Suspension is the most common advisory, noted on 47.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 30.3% in 2021 to 17.3% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 47.3% | 255 |
| 2 | Brakes | 42.1% | 227 |

| 5 | Emissions & environmental | 16.0% | 86 |
| 6 | Lighting & signalling | 12.2% | 66 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

| 0-30k | 45 | 17.8% |
| 30-60k | 89 | 20.2% |
| 60-90k | 117 | 21.4% |
| 90-120k | 143 | 30.8% |
| 120-150k | 80 | 30.0% |
| 150k+ | 46 | 30.4% |

What to check before buying a 1999 Frontera
The failure pattern for this year is specific enough to inspect against: brakes accounted for 13.2% of tests. Start there.
- Brakes (13.2% 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.
- Body, structure & corrosion (12.6% 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 (11.1% 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.
