Nissan Sunny MOT Failures

An analysis of 3,888 real DVSA MOT tests on the Nissan Sunny — what fails, how often, and how that compares to every other car on UK roads. Generations covered: B12 (1986–1991), N14 (1990–2000).

Where the Nissan Sunny fails its MOT

The single biggest MOT failure point on the Nissan Sunny is abs fault — this model is 30 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 3,888 MOT tests, 23.27% of all Nissan Sunny tests recorded this as a failure.

Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.

Other notable weak points include steering rack wear (47x the fleet average), anti-roll bar links worn (39x the fleet average), structural corrosion (29x the fleet average), and vehicle structure corroded to the extent that t... (18x the fleet average). These ratios compare the Nissan Sunny'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: Suspension, Steering, Bodywork, Seatbelts & Airbags. If you're inspecting a Nissan Sunny 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 Sunny'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 Sunny specifically, the DVSA data shows the most common failures at this mileage are power steering fault (229x the average) and abs fault (30x). transmission shaft constant velocity joint boot... (22x) and anti-roll bar links worn (19x) 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 Sunny specifically, the DVSA data shows the most common failures at this mileage are steering rack wear (47x the average) and anti-roll bar links worn (39x). structural corrosion (29x) and abs fault (25x) also appear frequently.

The shift from power steering fault at lower mileages to steering rack wear 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 Sunny specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.

Subframe mounting point corrosion (N14) Dangerous

The load-bearing structure around subframe mounting points suffers severe corrosion on N14-generation Sunny models, particularly around the rear suspension pickup points and front subframe attachments. Affects N14; typical independent garage repair cost is £800–£2,000.

General body structure corrosion (N14) Major

N14 Sunny models suffer from widespread structural corrosion that reduces the rigidity of the vehicle assembly. Affects N14; typical independent garage repair cost is £1,200–£3,000.

Suspension bush and joint wear (N14) Major

Suspension bushes and joints on the N14 Sunny wear at an accelerated rate, with MOT data showing 18.3 times higher failure rates than the national average. Affects N14; typical independent garage repair cost is £200–£600.

Coil spring fracture (N14) Major

Coil springs on N14 Sunny models fracture at 7.1 times the national fleet average, with both front and rear springs affected. Affects N14; typical independent garage repair cost is £150–£300.

What to check before buying a Nissan Sunny

Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Nissan Sunny:

Suspension — check for abs fault, anti-roll bar links worn. Steering — check for steering rack wear, power steering fault. Bodywork — check for structural corrosion, vehicle structure corroded to the extent that t..., transmission shaft constant velocity joint boot....

Beyond the MOT items, ask specifically about subframe mounting point corrosion and general body structure corrosion. 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.
