By fuel type, the one with the fewest documented faults is: Electric.

We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.

Official recalls: ask before you pay

We have no official recalls on record for this model. Our list is not complete: ask anyway, with the chassis number.

  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 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.
  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.
