The picture
Across 1,323 MOT tests, the Nv400 Acenta Dci returns 68.7% first-time pass — well below the UK fleet average. The single most-logged Major fail is windscreen damage. A number-plate lamp out and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 58,963, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 1.4-point gap between bands is modest — the year you buy Nissan Nv400 Acenta Dci makes a small but real difference to MOT outcomes.
Best band to buy
69.3%
2021+ registration
the 2021-on band climbs to 69.3% — a 1.4-point improvement. Tests in this band average 51,839 miles — roughly 17K miles fewer on the clock than the older band. Failures here are mostly wear items: damaged but not adversely affecting driver's view, inoperative in the case of multiple lamps… — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
67.9%
2018–2020 registration
On the 2018–2020 band, the data shows a 67.9% pass rate against a fleet average of 69.3% on the newer band. The main culprits logged at test: inoperative in the case of multiple lamps…, damaged but not adversely affecting driver's view, and less than 1.5 mm thick. Average mileage on test for this band is 68,577 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (69.3% first-time pass). Worst band to avoid: 2018-2020 (67.9% pass). That's a 1.4-point spread across 561 older tests and 762 newer ones — year of build makes a material difference on this model.
