INFINITI Q30 Common Problems & Reliability

Based on 377 MOT tests from 44 vehicles analysed by VehicleScore®. The figures below describe that VehicleScore® sample. Recurring issues seen in VehicleScore® MOT data are not a claim that every INFINITI Q30 has the same fault.

INFINITI Q30's have a very good reliability rating of 743/999. The score was calculated from the average of every INFINITI Q30 that has had a registered MOT.

We calculated all of the below figures by getting the score from each vehicle make/model/year/fuel, which are each calculated a score. We then generate the average score, taking into account factors such as mileage and emissions.

Also check BHP & performance, road tax, fuel economy, and CO2 emissions for the INFINITI Q30.

Common INFINITI Q30 MOT problems

These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.

Tyre wear

VehicleScore® MOT data includes 88 advisory comments and 14 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.

What to inspect

Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

Example MOT wording: NEARSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Brake disc wear

VehicleScore® MOT data includes 22 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record brake discs that were worn, scored, pitted, or corroded.

What to inspect

Look at the disc faces for deep scoring, a lip at the edge, and corrosion.

Example MOT wording: FRONT BRAKE DISC WORN, BUT NOT EXCESSIVELY (1.1.14 (A) (I))

Brake pad wear

VehicleScore® MOT data includes 13 advisory comments and 5 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record brake pads that were worn or below the inspection limit.

Coil spring issues

VehicleScore® MOT data includes 6 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record coil springs that were corroded, fractured, or otherwise defective. They are counted separately from shock absorbers.

What to inspect

Look for a broken or heavily corroded spring and compare the ride height on both sides.

Example MOT wording: NEARSIDE REAR COIL SPRING FRACTURED OR BROKEN (5.3.1 (B) (I))

Engine warning lamp

VehicleScore® MOT data includes 4 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record an engine warning lamp that was on, or did not work, during the inspection.

Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.

Example MOT wording: ENGINE MIL INOPERATIVE OR INDICATES A MALFUNCTION (8.2.2.2 (G))

What to check when buying a used INFINITI Q30

This is an inspection checklist based on MOT comments in the VehicleScore® sample. It does not mean the car you are looking at has these defects.

  • Tyre wear. Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

  • Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.

  • Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.

  • Anti-roll bar issues. Listen for a knock when driving over uneven ground at low speed.

  • Coil spring issues. Look for a broken or heavily corroded spring and compare the ride height on both sides.

  • Engine warning lamp. Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.

  • Lamp and bulb faults. Switch on the side, brake, fog, and number-plate lamps.

Buying a INFINITI Q30?

Common problems tell you what can affect INFINITI Q30s generally. VehicleScore® can check the history of the actual car you're considering.

Where does this data come from?

VehicleScore® analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
