KIA NIRO Common Problems & Reliability

Based on 1,421 MOT tests from 357 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 289 advisory comments and 66 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 32 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))

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))

Windscreen damage

VehicleScore® MOT data includes 11 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))

Headlamp 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 headlamp that was not working, insecure, or aimed incorrectly.

What to inspect

Switch on dipped and main beam and look for a cloudy lens or a wrong aim.

Example MOT wording: NEARSIDE FRONT HEADLAMP NOT WORKING ON DIPPED BEAM (4.1.1 (A) (II))

KIA NIRO MOT reliability by 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.
Registration plate condition. Check both plates are secure, clean, and clearly readable.
Windscreen damage. Look for chips and cracks, especially in the area swept by the wipers.
Headlamp faults. Switch on dipped and main beam and look for a cloudy lens or a wrong aim.

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.
