2015 Suzuki Celerio — MOT failures & pass rate
Across 39,770 MOT tests, the 2015 Suzuki Celerio recorded a 90.0% pass rate. That is 5.6 percentage points better than city cars of a similar age, which fail at 15.5%. Failures cluster in lighting & signalling, visibility and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (5.3%) and visibility (5.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, stop lamp and rigid brake pipes — wipers alone was recorded 1,830 times.
A 150k+ example is materially riskier than a 0-30k one: 18.0% versus 6.3%.
Tyres is the most common advisory, noted on 25.2% of tests — work that passed today but is likely due soon.
The trend is worsening — 7.4% of tests failed in 2021 against 12.5% 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 | 25.2% | 10,022 |
| 2 | Brakes | 18.2% | 7,245 |

| 5 | Visibility | 3.4% | 1,360 |
| 6 | Lighting & signalling | 2.6% | 1,038 |
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 | 13,463 | 6.3% |
| 30-60k | 17,877 | 10.2% |
| 60-90k | 6,353 | 14.2% |
| 90-120k | 1,533 | 18.0% |
| 120-150k | 396 | 21.0% |
| 150k+ | 128 | 18.0% |

What to check before buying a 2015 Celerio
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 5.3% of tests. Start there.
- Lighting & signalling (5.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (5.0% 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 (4.0% 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.
