The passenger-side air bag in our 2010 Legacy is turning off intermittently and spontaneously while the car is in motion, although the passenger seat is occupied by a 120-pound person. The bag is deactivating even though the seat is securely locked into position as far from the dashboard as it will move, and nothing is placed beneath the passengers seat. To reactivate the air bag, it is necessary to stop, then to restart the engine, and that maneuver is frequently not feasible in either heavy freeway traffic, or on remote highways that lack shoulders. The rebooting procedure indicates that the problem is not any sensor for the seat it is a problem with the computer operating the air bag. The dealer is unable to treat this problem.
