Every Infiniti Q30 model year
Pass rates fall as cars age, so the only fair comparison for a 2018 car is other cars of the same age. The full run for the Infiniti Q30:

|---|---|---|---|
| 2016 | 84.6% | 1,777 | 67,640 |

The 2018 is one of the stronger years for this model, passing 6 points more often than the Infiniti Q30 average.

What an 8-year-old car fails on
A 2018 car is 8 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:
- Lights and electrical: 10.36% of all cars tested
- Suspension: 8.65% of all cars tested
- Tyres: 6.23% of all cars tested
- Brakes: 6.1% of all cars tested
- Visibility: wipers, washers, glass: 4.65% of all cars tested
- Body, chassis and structure: 3.18% of all cars tested
That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck. On a 2018 Infiniti Q30 the average at test was 47,520 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.
2018 is the strongest year on record for this model at 91.6%, ahead of every other year we hold data for.
