One problem related to air bag has been reported for the 2004 Ford F-250. The most recently reported issues are listed below.
I was involved in an accident driving my 04 Ford f250 diesel pulling a 25 ft fifth wheel. A car pulled out in front of me on the highway. I swerved to try to miss, but hit the cars left front end. We went off the road, down the ditch, up the ditch and into a grove of trees. Hit a tree right in the middle of the bumper. Both my wife's and my eyeglasses flew off. My wife suffered a severe chest bruise from the seat belt. My concern and question why didn't the air bags deploy? I was traveling about 55mph and would guess about 40mph when we hit the ditch. Both the truck and camper were totaled. The camper ended up flipped over on it's side.
