Has anyone ever heard of both front airbags going off while just driving down the road? Both front airbags plus the driver's seatbelt tensioner deployed today on my son's '98 2.8 while he was cruising down the highway at 70 mph (smooth, straight road, perfect weather). The guibo broke (it was only 1 year old), so I'm sure that's what triggered the airbags, buy why?

This same car hit a deer at 50 mph (no deployment)4 years ago and also hit a truck tire tread at 70 mph (no deployment) 2 years ago. Perhaps this was just a delayed reaction to those incidents.
