The 2003 Subaru Baja has 11 recalls, the most serious being a long-running passenger-side frontal airbag inflator defect where the inflator can rupture during deployment and send metal fragments into the cabin, risking serious injury or death.
All but one of the recalls concern this same airbag inflator problem, which has been addressed through multiple repair campaigns over the years. The propellant inside the passenger frontal airbag inflator can degrade over time, especially in vehicles exposed to high heat and humidity, causing the inflator to burst with far greater force than intended. One of the campaigns specifically covers vehicles where an earlier inflator replacement was performed but did not provide a permanent fix, and that campaign represents a final remedy for those previously repaired vehicles. The geographic scope of some campaigns is limited to certain states, reflecting the role that regional climate plays in accelerating propellant degradation, so owners in cooler, drier areas may fall under different filings than those in warmer or more humid regions.
On the mechanical side, there is one engine recall affecting only four-cylinder models. The water pump pulley can work loose from the pump shaft, and if it separates while the engine is running, it can cause severe internal engine damage, potentially leaving the vehicle undrivable.

What can fail
The passenger-front airbag inflator's propellant can degrade over time from heat and humidity exposure. A degraded inflator may deploy with excessive force, rupture, or fail to work properly.
What the fix does
A dealer will inspect the passenger-front airbag inflator and replace it if needed to restore proper function.

What can fail
Heat and humidity can break down the propellant in the passenger front airbag over time. This may cause the airbag to inflate with excessive force during a crash, potentially sending fragments toward occupants and damaging the airbag assembly.

What can fail
Moisture can seep into the passenger side front air bag inflator. Over time, this causes the inflator to rupture when the air bag deploys.
