Before you buy a used Peugeot iOn.
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.

The essentials.
- 1 documented, sourced fault for its engine.
- That is not much data: if no other faults show up here, it does not mean it has none.
- It only applies with certain equipment or production dates: ask what this car has.
- 1 official recall on record: ask for the chassis number (VIN) and confirm it has been done.
Typical faults by engine
The period and mileage are those mentioned by each sheet's sources. They are not a maintenance interval and do not predict that any particular car will fail.

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.
- 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.
- Ask an official Peugeot 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.
- 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.

High-voltage battery
Look out for: Total failure of the traction battery (sometimes only one or two cells need replacing); loss of power from the control unit; a windscreen that cracks by itself, rattles, poor demisting and a flimsy rear structure.
Ask them to check: Ask for a battery health report; check the campaign by VIN.
