Side/window Air Bag problems of the 2010 Chevrolet Express

The side airbags deployed while driving down the road at about 10 mph. We had just turned out of our driveway and heading to a stop sign at the highway. Luckily it happened before getting on the highway. Nothing hit the van and no prior damage. My wife was driving and she has bruising on her arm and we both have ringing and sore ears. Sounded like a bomb went off inside the van. We were kind of disoriented and feel like we may have blacked out for a bit after it happened. We have not seeked medical yet but might in the next couple days if some of the issues don't get better.
