This Renault Trafic diesel van falls slightly short of the UK average with a 76.2% first-time pass rate against the national 80%, and nearly a quarter of vehicles in this cohort have recorded dangerous defects—a material concern for a commercial vehicle. The diesel engine itself is the likely culprit here, as these issues tend to cluster around emissions and brake systems rather than suggesting across-the-board unreliability.

At just under 64,000 miles average for a 2021, these vans are running fairly light for their age, which partly explains the moderate failure rate of 0.76 per vehicle. The real story is in the 2.9 advisories per test, pointing to wear items like suspension bushes, brake pads, and DPF clogging rather than major structural problems—so budget for regular maintenance, and before buying one, have an independent diesel specialist inspect the turbo and fuel injection system, which are the expensive components to get wrong on these engines.

We have limited data for the 2021 Renault Trafic Sl30 B Ness Energy DCI — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 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.
