Before you buy a used Mazda Mazda3 (BM/BN).

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 across its 2 engines.
That is not much data: if no other faults show up here, it does not mean it has none.
7 official recalls on record: ask for the chassis number (VIN) and confirm they have been done.
According to the data we have, all its engines have the same number of documented faults.

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 Mazda 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.
