Should I check the MOT history before buying a 2021 Renault Trafic Sl28 B Ness+ Energy DCI?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2021 Renault Trafic Sl28 B Ness+ Energy DCI?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2021 Renault Trafic Sl28 B Ness+ Energy DCI?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Based on MOT data from 1,504 vehicles, the 2021 Renault Trafic Sl28 B Ness+ Energy DCI has a first-time MOT pass rate of 83.9%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Renault Trafic Sl28 B Ness+ Energy DCI?

This Renault Trafic diesel van is slightly more reliable than the UK average, with an 83.1% first-time MOT pass rate compared to the national 80%, and a low 16.4% of vehicles ever flagged for dangerous defects—well within acceptable bounds for a commercial workhorse. The median mileage of 54,751 miles is reasonable for a 2021 model, suggesting these vans are being run hard but not abused, with an average of 0.52 failures per vehicle indicating they hold up reasonably well mechanically.

At 2.2 advisories per test, you should expect minor wear items to crop up regularly—typical for a van that spends its life on the road—so budget for things like brake pad wear and suspension components. If you're considering buying one, get a pre-purchase inspection done by a diesel specialist, as these engines are solid but need proper servicing to stay that way.

The 2021 Renault Trafic Sl28 B Ness+ Energy DCI passes its MOT first time at roughly the UK average rate (83.9%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 2.2 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,504 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
