1998 Dodge Durango SLT review from North America

We bought our vehicle used and have no problems with it. We have taken it on several out of state trips with no problems and great gas mileage. The problem that I have is my husband was in a collision which damaged both front fenders, hood, front grill, front bumper, radiator & fan. This was a total of about $6000. damage. My 11 year old grandson was with him when this happened and both had seat belts on. The airbags never did deploy. I called 2 dealerships and asked if they knew of a reason why. The first told me to bring this vehicle that can not be driven to them and they would put the computer on it to find out why. I work at a auto repair shop and have the computer. The 2nd dealership said there is no speed of impact that he could tell me that would make the airbags deploy. If this is true then why have them? If my grandson had not had his seatbelt on he would have gone through the windshield because of no airbag.
