Summary
The Mazda B-Series Truck has 9 recalls covering the entire 2004-2009 production run, all involving the front airbag inflators, with the most serious risk being that either the driver or passenger inflator can rupture and send metal fragments into the cabin during a crash.
Every recall on these vehicles traces back to the same fundamental problem: the frontal airbag inflators, on both the driver and passenger sides, can build excessive pressure and explode rather than deploy cleanly. The 2006 model year carries the most urgent designation, as recalls for that year included a stop-drive advisory, meaning owners were asked not to drive until the vehicles were repaired. Across the 2004-2006 model years, both the driver-side and passenger-side inflators are covered. The 2007-2009 model years are subject to the same inflator rupture risk on both sides as well, with the passenger-side recalls for those years broken out by geographic region based on climate, since heat and humidity accelerate propellant degradation inside the inflators. All 2009 models registered in cooler northern states are also covered for the passenger side. There is also a follow-on recall covering 2004-2006 vehicles that had the passenger-side inflator replaced under an earlier campaign, where the replacement inflator may have been installed incorrectly and could fail to inflate properly in a crash.
