2018-19 Mazda CX-5 and 6, 2019 Mazda 3 recalled

Mazda has recalled the 2018-19 CX-5 and 6, and the 2019 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'.
