2014 Toyota Iq — MOT failures & pass rate
4,566 MOT tests on the 2014 Toyota Iq are in this dataset, and 91.2% of them passed. Against city cars of a similar age (17.3% fail rate), the 2014 Iq comes out 8.6pp better. Failures cluster in lighting & signalling, visibility and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (5.7%) and visibility (3.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and position lamp — wipers alone was recorded 170 times.
A 150k+ example is materially riskier than a 0-30k one: 30.9% versus 5.8%.
Advisories point at the next bill rather than this one: tyres was flagged on 19.7% of tests without failing them.
The trend is worsening — 7.0% of tests failed in 2021 against 11.0% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 19.7% | 898 |
| 2 | Brakes | 19.4% | 888 |

| 4 | Visibility | 3.9% | 176 |
| 5 | Lighting & signalling | 3.7% | 168 |
| 6 | Other defects | 3.4% | 155 |
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 | 1,583 | 5.8% |
| 30-60k | 2,035 | 9.2% |

| 90-120k | 161 | 10.6% |
| 120-150k | 41 | 17.1% |
| 150k+ | 42 | 30.9% |

What to check before buying a 2014 Iq
On a 2014 Iq, lighting & signalling is what the MOT record says goes wrong most — it appeared in 5.7% of tests. Check these areas before you commit.
- Lighting & signalling (5.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (3.8% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Brakes (2.6% 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.
