2006 Daihatsu Terios — MOT failures & pass rate
Across 4,757 MOT tests, the 2006 Daihatsu Terios recorded a 72.4% pass rate. Small SUVs of a similar age fail at 27.7%, so the 2006 Terios sits squarely on the average. Failures cluster in suspension, brakes and lighting & signalling.
What the MOT record shows
Suspension dominates the failure mix at 14.3% of all tests — 3.3 points clear of brakes, so it is the first thing to check.
At component level the recurring items are component mounting prescribed areas, catalyst emissions and prescribed areas — component mounting prescribed areas alone was recorded 714 times.
A 150k+ example is materially riskier than a 0-30k one: 33.3% versus 15.4%.
Advisories point at the next bill rather than this one: suspension was flagged on 40.9% of tests without failing them.
The trend is worsening — 26.7% of tests failed in 2021 against 29.7% in 2025, the usual pattern as a fleet ages.

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

| 5 | Other defects | 11.4% | 541 |
| 6 | Lighting & signalling | 10.1% | 481 |
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 | 104 | 15.4% |
| 30-60k | 740 | 19.2% |
| 60-90k | 1,587 | 26.5% |

What to check before buying a 2006 Terios
On a 2006 Terios, suspension is what the MOT record says goes wrong most — it appeared in 14.3% of tests. Check these areas before you commit.
- Suspension (14.3% 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 (11.0% 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.
- Lighting & signalling (10.3% 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.
