These vehicles had their passenger front airbag inflators previously replaced under a prior recall using inflators of the same design.
The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.
An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
What to do
Mazda will notify owners, and dealers will replace the front passenger airbag inflator with an alternate one free of charge.
The recall is expected to begin December 18, 2019.
Owners may contact Mazda customer service at (800) 222-5500, option 4. Mazda's number for this recall is 2618F.
