Powertrain Control Modules Concern

Mazda North American Operations

July 10, 2019

WASHINGTON, DC (July 10, 2019) – Mazda North American Operations has filed a Part 573 notification with the National Highway Traffic Safety Administration (NHTSA) for a safety defect on certain 2018 and 2019 Model Year CX-5, Mazda6, and 2019 Mazda3 vehicles. Loss of engine power or engine stall without the ability to be restarted can occur while driving, which may increase the risk of a crash. Mazda’s recall number is 3719F

On certain Powertrain Control Modules (PCM), the software controlling the hydraulic valve clearance adjuster may operate improperly when transitioning from cylinder deactivation to full cylinder activation modes. As a result, an intake valve rocker arm may come out of position and make contact with internal engine parts, which may cause an engine misfire, loss of engine power, and/or Malfunction Indicator Light (MIL) illumination.

Affected vehicles referenced below were manufactured at Mazda in Japan unless noted:

MY 2018 Mazda CX-5 – 143,004 units
MY 2019 Mazda CX-5 – 81,236 units
MY 2018 Mazda6 – 18,295 units
MY 2019 Mazda6 – 2,551 units
MY 2019 Mazda3 – 14,483 units
MY 2019 Mazda3 – 2,651 units (built at Mazda de Mexico Vehicle Operations)

No accidents, injuries, or deaths have been reported from the field to date as a result of this defect.
