    Mileage mentioned
    What the sheet says: The Dutch consumer programme Radar (2025) explains that these models were fitted with a Mahle on-board charger that fails relatively often and that Stellantis changed supplier without a recall. In 2021 Stellantis extended the charger warranty to four years on nearly all of them (not the Fiats), and Toyota covers its Proace for five years or 200,000 km; out of warranty it costs thousands of euros. Belgian consumer association Test-Achats publishes an owner’s complaint with the same list of models.

    Applies if: Only vans built from 2020 to 2023 (Mahle charger).

Official recalls: ask before you pay

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

  1. Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
  2. Ask an official Fiat dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
  3. Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

0 of 4 checked

Timing / lubrication

  • Look out for: Oil pressure warning, hard brake pedal or reduced assistance, oil consumption, blue smoke, squeal at the front of the engine, turbo whistles or loses power.

    Ask them to check: Measure the belt through the oil filler opening with the manufacturer's tool. Confirm whether the vacuum pump campaign was done.

Exhaust and emissions (AdBlue)

  • Look out for: Emission system fault message and a “starting impossible in X km” countdown, AdBlue/UREA warning and engine light.

    Ask them to check: Diagnose with Diagbox or equivalent: AdBlue pressure, flow test and tank temperature.

Timing system

  • Look out for: Rattle from the top of the engine, loss of power; in severe cases the chain breaks and the engine fails.

    Ask them to check: Ask the dealer whether the car is in the campaign (free inspection and replacement if needed) and whether the 8 mm chain is fitted.

High-voltage battery

  • Look out for: It stops charging on AC (at home or at public posts) while still charging at DC rapid chargers; charging-fault warnings.

    Ask them to check: Try charging at an AC post before buying; ask the dealer for the build date and whether the charger has already been replaced; keep the invoice in case you claim non-conformity.
