2023 Suzuki SX4 — MOT failures & pass rate
The 2023 Suzuki SX4 passed 94.8% of its 286 recorded MOT tests. Small SUVs of a similar age fail at 5.1%, so the 2023 SX4 sits squarely on the average. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (2.1%) and visibility (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, washers and front fog lamps — tread depth alone was recorded 6 times.
Advisories point at the next bill rather than this one: tyres was flagged on 13.6% of tests without failing them.

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 | 13.6% | 39 |
| 2 | Other defects | 7.3% | 21 |
| 3 | Brakes | 6.3% | 18 |
| 4 | Suspension | 4.2% | 12 |
| 5 | Visibility | 2.1% | 6 |
| 6 | Steering | 0.4% | 1 |
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 | 212 | 2.4% |
| 30-60k | 59 | 8.5% |
What to check before buying a 2023 SX4
On a 2023 SX4, tyres is what the MOT record says goes wrong most — it appeared in 2.1% of tests. Check these areas before you commit.
- Tyres (2.1% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (2.1% 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.
- Lighting & signalling (1.4% 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.
