The 2009 Mazda6 has 15 recalls, the most serious being a passenger-side frontal airbag inflator that can rupture and send metal fragments into the cabin, causing serious injury or death.
This airbag inflator issue has a long history on this vehicle: prior repair attempts using replacement inflators of the same design did not resolve the problem, and those replacements are covered by their own recall. There is also a separate airbag concern where the airbag control unit can corrode internally due to improper coating, causing the airbag warning light to illuminate and preventing airbags and seatbelt pretensioners from deploying in a crash.
On the fuel system side, a particular spider species can weave webs inside the evaporative canister vent line, blocking it and causing the fuel tank to build up excessive negative pressure. Over time this stress can crack the tank and allow fuel to leak, raising the risk of fire. This recall specifically affects 2.5L engine models.
Two structural concerns involve corrosion: the passenger-side lower control arm mounting point can rust and weaken, causing unexpected steering changes, and the front crossmember can rust in vehicles regularly exposed to road salt.
Door security is a recurring theme across several recalls. Door handles can stick or latch mounting screws can loosen, in either case allowing a door to swing open while driving.

What can fail
Door latch screws can loosen over time, preventing doors from latching fully when closed and triggering a door ajar warning light. If driven this way, doors may open while moving.
What the fix does
Dealers will inspect the door latch screws and re-tighten or replace them as needed.

What can fail
A spider may build a web in the fuel tank vent line, blocking airflow. This causes the fuel tank to develop excessive negative pressure during emission system operation, which can crack the tank over time and cause fuel to leak.
What the fix does
The dealer will clean the vent line, install a spring to prevent spider entry, and reprogram the engine computer to prevent excessive tank pressure. Any damaged tank or vent valve will be replaced.
Summarized — see the official notice for exact wording, dates, and contacts.

What can fail
A spider species can build a web inside the evaporative canister vent line, blocking airflow. When the emission system purges fuel tank vapors, excessive negative pressure builds in the tank.
What the fix does
Dealers will inspect and clean the vent line, then install a spring to block spiders from entering it. Service is free.
