LEXUS NX Common Problems & Reliability

Based on 1,159 MOT tests from 209 vehicles analysed by VehicleScore®. The figures below describe that VehicleScore® sample. Recurring issues seen in VehicleScore® MOT data are not a claim that every LEXUS NX has the same fault.

LEXUS NX's have a excellent reliability rating of 850/999. The score was calculated from the average of every LEXUS NX 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 LEXUS NX.

Common LEXUS NX 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 282 advisory comments and 27 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 check when buying a used LEXUS NX

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.
Suspension arm issues. Look for play or corrosion at the arm and ask whether it has been replaced.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Windscreen damage. Look for chips and cracks, especially in the area swept by the wipers.
Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Seatbelt faults. Buckle every belt and confirm it locks and releases.

Buying a LEXUS NX?

Common problems tell you what can affect LEXUS NXs 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.
