Expert verdict
Tyres: 1.7× the national share
Tyres make up 34.0% of everything recorded on the 2017 Infiniti Qx30, against 19.8% nationally — 14.2 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- When it fails, it costs. Only 22% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2017 QX30
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2017 QX30
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the coil springs 3.6% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
-
Check the lights 1.2% of tests
“headlamp aim too low”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the suspension joints 0.9% of tests
“linkage ball joint dust cover ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

| Tread depth below requirements of 1.6mm Tyres | Advisory | 12.4% | £45–95 |
