2016 Infiniti Qx30 — MOT failures & pass rate
The 2016 Infiniti Qx30 passed 90.3% of its 289 recorded MOT tests. That is 4.9 percentage points better than all cars of a similar age, which fail at 14.6%. Failures cluster in suspension, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (3.1%) and brakes (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, headlamp and brake pads — coil spring alone was recorded 6 times.
Mileage matters less than usual here: the 2016 Qx30 fails 6.5% of the time in the 0-30k band and 8.3% at 60-90k, a spread of only 1.8 points.
Advisories point at the next bill rather than this one: brakes was flagged on 23.9% of tests without failing them.
The trend is worsening — 3.6% of tests failed in 2021 against 14.0% in 2025, the usual pattern as a fleet ages.

| 0-30k | 46 | 6.5% |
| 30-60k | 148 | 10.1% |
| 60-90k | 72 | 8.3% |
Failure rate by age
Trend over time

What to check before buying a 2016 Qx30
On a 2016 Qx30, suspension is what the MOT record says goes wrong most — it appeared in 3.1% of tests. Check these areas before you commit.
- Suspension (3.1% 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 (2.1% 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 (2.1% 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.
