The top reasons vans fail their MOT

If you drive a van, you already know it works harder than the average car. Long days, heavy loads, endless miles. So, when MOT time rolls around, the stakes feel higher – and the data backs that up. Vans fail their MOT more often than cars, and for very different reasons.

A couple of months ago, we explored which van models are most likely to fail their MOT. Now we’re looking at the why – the faults most likely to cause a fail, how often they happen, and what this says about how long vans really last on the road.

The 25 most common van MOT fail reasons

According to DVSA vehicle history data, these are the faults most likely to bring a van to a halt come MOT time. The numbers show just how often these issues crop up:

Rank	Fail Reason	Number of Fails

The top failure reasons explained

Handbrake efficiency

This isn’t just the top reason vans fail – it’s miles ahead of every other fault.

Vans carry heavier loads, park on more varied terrain, and often spend long hours stop‑starting in traffic. All that strain puts extra pressure on the handbrake mechanism. And because handbrake wear is gradual, many drivers don’t notice a problem until MOT day.

Interestingly, handbrake issues are also the most common cause of MOT failure in cars – but the scale is far higher in vans.

Registration plate lamps

Cars rarely fail for a number plate bulb. But vans? They fail for it a lot. Why?

Because vans take more knocks. Rear doors slam harder. Loads shift. Bulbs rattle loose. And because registration lamps sit low on many vans, they’re more exposed to dirt, salt, and water – all things that ruin wiring.

A blown plate bulb sounds small, but it’s a legal requirement and can carry a fine of up to £1,000 if the plate isn’t properly lit.

Windscreen wipers and washers

Vans do long motorway miles, early starts, late finishes, and plenty of winter driving. Wipers take a beating. And while a smeary windscreen might feel like a minor annoyance, it’s an instant MOT fail.

Washers failing because they’re empty is surprisingly common too – something easily fixed before the test.

How long do vans last before their first MOT failure?

Using DVSA data for van models manufactured for more than 5 years (and with 5,000+ recorded tests), we can see how long different makes last before failing their MOT for the first time. And there’s a clear winner; many VW vans go over 15 years before their first recorded fail.

Rank	Make	Average Age at First MOT Fail
1	Volkswagen	15 years 7 months
2	Toyota	11 years 9 months
3	Fiat	11 years 3 months
4	Suzuki	11 years
5	Renault	10 years 11 months
6	Peugeot	10 years 8 months
7	Daihatsu	10 years 6 months
8	IVECO	10 years 6 months
9	Ford	10 years 3 months
10	Vauxhall	10 years 3 months
11	LDV	10 years
12	Mercedes-Benz	10 years
13	Citroen	9 years 6 months
14	Nissan	9 years 2 months
15	Mitsubishi	9 years 2 months
16	MAN	3 years

Why vans wear down faster than cars

Vans aren’t just used differently – they’re used harder. Here’s what accelerates wear:

1. Long mileage days

Many vans clock more miles in a year than some cars manage in five. More miles = more mechanical wear.

2. Heavy loads

Most cars aren’t expected to haul tools, equipment, parcels or stock daily. But many vans do just this! Suspension, brakes, handbrakes and tyres all take the hit.
