Nissan Nv400 MOT Failures
An analysis of 138,367 real DVSA MOT tests on the Nissan Nv400 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: NV400 (2011–2021).
Where the Nissan Nv400 fails its MOT
The single biggest MOT failure point on the Nissan Nv400 is light unit fault — this model is 276 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 138,367 MOT tests, 2.17% of all Nissan Nv400 tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include lamp missing, inoperative or in the case of a m... (185x the fleet average), sharp bodywork damage (36x the fleet average), body panel damage (35x the fleet average), and obligatory mirror or device inoperative, damage... (16x the fleet average). These ratios compare the Nissan Nv400's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 4 categories: Lights & Electrics, Bodywork, Wipers & Windscreen, Steering. If you're inspecting a Nissan Nv400 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Nissan Nv400's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Nissan Nv400 specifically, the DVSA data shows the most common failures at this mileage are lamp missing, inoperative or in the case of a m... (41x the average) and sharp bodywork damage (36x). body panel damage (35x) and emissions failure (23x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Nissan Nv400 specifically, the DVSA data shows the most common failures at this mileage are lamp missing, inoperative or in the case of a m... (185x the average) and switch does not operate in accordance with the ... (183x). lamp with a multiple light source up to 1/2 not... (145x) and light unit fault (117x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Nissan Nv400 specifically, the DVSA data shows the most common failures at this mileage are lamp with a multiple light source up to 1/2 not... (173x the average) and lamp missing, inoperative or in the case of a m... (73x). light unit fault (63x) and coil springs broken (13x) also appear frequently.
The shift from lamp missing, inoperative or in the case of a m... at lower mileages to lamp with a multiple light source up to 1/2 not... at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Nissan Nv400 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Severe body panel corrosion and damage Dangerous
MOT data shows this model fails body panel inspections at 24 times the national average, with peak failure rates between 60,000-80,000 miles. Affects NV400; typical independent garage repair cost is £800–£2,500.
Brake pipe corrosion and flexible hose damage Dangerous
Brake pipe damage occurs at 4.5 times the fleet average and flexible brake hose damage occurs at 7.0 times the average. Affects NV400; typical independent garage repair cost is £200–£600.
Engine management light activation Major
The MIL (malfunction indicator light) activates at Peak failure occurs on very low mileage vehicles (0-20,000 miles), suggesting underlying software or sensor calibration issues rather than wear-related problems. Affects NV400; typical independent garage repair cost is £150–£800.
Brake pedal anti-slip provision failure Major
The brake pedal anti-slip provision fails at 10.3 times the national average, with peak failures occurring at 40,000-60,000 miles. Affects NV400; typical independent garage repair cost is £25–£60.

What to check before buying a Nissan Nv400
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Nissan Nv400:
Lights & Electrics — check for light unit fault, lamp missing, inoperative or in the case of a m..., lamp with a multiple light source up to 1/2 not.... Bodywork — check for sharp bodywork damage. Wipers & Windscreen — check for body panel damage, obligatory mirror or device inoperative, damage..., windscreen or window damaged or seriously disco....
Beyond the MOT items, ask specifically about severe body panel corrosion and damage and brake pipe corrosion and flexible hose damage. These won't show up on a standard MOT but can be expensive to fix — repairs start from £800. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
