Here is a scene from an accident in Scottsdale. A client of ours had their windshield installed improperly by another company a few years back. His wife and daughter were in an accident heavy enough to cause the airbags to deploy. The airbag launched the windshield out of the vehicle causing the airbag to not function properly which led to more serious injuries to his daughter.
Generally, this is caused by not priming the glass and having the knowledge of a proper install.
