KIA NIRO Common Problems & Reliability

Based on 1,256 MOT tests from 315 vehicles analysed by VehicleScore. The figures below describe that VehicleScore sample. Recurring issues seen in VehicleScore MOT data are not a claim that every KIA NIRO has the same fault.

KIA NIRO's have a extremely good reliability rating of 831/999. The score was calculated from the average of every KIA NIRO 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 KIA NIRO.

Common KIA NIRO 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 249 advisory comments and 58 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: OFFSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Brake disc wear

VehicleScore MOT data includes 21 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: REAR BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))

Windscreen damage

VehicleScore MOT data includes 14 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 chips, cracks, or other windscreen damage in the driver’s view.

What to inspect

Look for chips and cracks, especially in the area swept by the wipers.

Example MOT wording: OFFSIDE FRONT WINDSCREEN WIPER DOES NOT CLEAR THE WINDSCREEN EFFECTIVELY (3.4 (B) (II))

Registration plate condition

VehicleScore MOT data includes 11 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record a number plate that was deteriorated, insecure, or did not meet the plate rules.

What to inspect

Check both plates are secure, clean, and clearly readable.

Example MOT wording: REAR REGISTRATION PLATE DETERIORATED BUT NOT LIKELY TO BE MISREAD (0.1 (B))

Parking brake faults

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 a parking brake that did not hold well enough or had a component defect.

What to inspect

Test that the parking brake holds the car on a slope and releases cleanly.

Example MOT wording: PARKING BRAKE EFFICIENCY BELOW REQUIREMENTS (1.4.2 (A) (I))

KIA NIRO MOT reliability by year

A model year is only commented on when VehicleScore has at least 5 vehicles from that year.

What to check when buying a used KIA NIRO

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.
Windscreen damage. Look for chips and cracks, especially in the area swept by the wipers.
Registration plate condition. Check both plates are secure, clean, and clearly readable.
Parking brake faults. Test that the parking brake holds the car on a slope and releases cleanly.

Buying a KIA NIRO?

Common problems tell you what can affect KIA NIROs 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.
