Mazda Australia has recalled the 2018-19 CX-5 and Mazda 6, and the 2019 Mazda 3, over concerns about the powertrain control module.

According to the company, the software controlling the cylinder deactivation function mightn't operate correctly, and could make an intake valve rocker arm move out of position, putting it at risk of making contact with 'other internal engine parts'.

If the problem occurs, the engine warning light will illuminate. The engine could lose power, and might stall without the ability to restart.

A total of 18,719 vehicles are included in the campaign – a VIN list is attached here.

Mazda will contact owners of the affected cars and advise them to organise a free fix with their nearest dealer.
