The 2015 Lexus Nx MOT pass rate is 91.6% of its MOT tests — 9.5 points ahead of what its age and mileage predict. Tyres is the biggest single reason it fails, at 33.7% of what testers record.
Expert verdict
Tyres: 1.7× the national share
Tyres make up 33.7% of everything recorded on the 2015 Lexus Nx, against 19.8% nationally — 13.9 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 82.1% and this one manages 91.6% — 9.5 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 32% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

Where the Lexus Nx is most common
Across all Nx model years on record (2014–2023): 44,337 Lexus Nx cars tested in a recordable postcode area, across 88,248 tests. London (NW) has the most, with 2,321 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Lexus Nx cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2015 Nx
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2015 Nx
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the suspension joints 2.8% of tests
“ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
Check the windscreen 2.1% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the wipers and washers 1.7% of tests
“wipers blade defective”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
