1997 Ford Explorer — MOT failures & pass rate
Across 290 MOT tests, the 1997 Ford Explorer recorded a 78.6% pass rate. That is 3.8 percentage points better than all cars of a similar age, which fail at 25.2%. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (11.0%) and lighting & signalling (10.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are ball joint dust cover, catalyst emissions and rear fog lamp — ball joint dust cover alone was recorded 14 times.
Mileage is the strongest signal on the record: 12.2% of 60-90k cars fail, rising to 23.3% once past 150k.
Suspension is the most common advisory, noted on 45.5% of tests — work that passed today but is likely due soon.

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 | 45.5% | 132 |
| 2 | Brakes | 29.3% | 85 |
| 3 | Body, structure & corrosion | 26.9% | 78 |
| 4 | Tyres | 18.6% | 54 |
| 5 | Emissions & environmental | 16.2% | 47 |
| 6 | Other defects | 15.5% | 45 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 41 | 12.2% |
| 90-120k | 96 | 27.1% |
| 120-150k | 80 | 21.3% |
| 150k+ | 43 | 23.3% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1997 Explorer
The failure pattern for this year is specific enough to inspect against: suspension accounted for 11.0% of tests. Start there.
- Suspension (11.0% 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 (10.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
