Are you about to buy a lemon?
Sellers rarely admit these faults outright. Our database tracks 8 specific phrases sellers use in adverts to soft-pedal these exact issues. Paste any Renault Trafic advert and we will check it in seconds.
Rear wheel arch corrosion, inner and outer, on the X83 Trafic and its Vauxhall Vivaro and Nissan Primastar siblings. Mud and salt pack between the inner and outer arch and rot it from behind, so the outer skin bubbles only once the inner arch is already going. It is common enough that several suppliers make model-specific inner and outer arch repair panels for this exact van, in short and long wheelbase versions.

Bodywork/ChassisHigh severity💬 Owner reports
Outer sill and side door step corrosion, and more seriously rot in the prescribed areas around the rear suspension and shock absorber mountings. The sills and door steps are where water drains and sits; the suspension mounting areas are structural, so corrosion there is an MOT failure and a much harder weld than an arch or a sill panel.
Rough guide
£300-1500
Typical symptoms
crusty or holed metal along the outer sill and the side door step
corrosion around the rear suspension and shock absorber mounting points
MOT advisories or failures citing corrosion within a prescribed area
patch plates welded over the sill or mounting areas

Renault Trafic service intervals: cambelt, chain and gearbox oil
An overdue cambelt is the most expensive thing a seller can fail to mention on a used Trafic. These are the figures UK specialists work to.
Timing chainChain
1.6 DCI, R9M, X82
No fixed replacement interval
Chain driven with no scheduled replacement, and not to be confused with the belt-driven 1.5 dCi. Fitted to the Trafic III from 2014 until the 2.0 Blue dCi replaced it around 2019-2020. Uprated heavy-duty aftermarket kits exist, which reflects wear cases on hard-worked vans, so investigate any start-up rattle.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.

Where this Renault Trafic fault data comes from
If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Renault Trafic owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Renault Trafic goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
