VEHICLE HYDROPLANED GOING 70 MPH AND WENT OFF ONE SIDE OF ROAD. VEHICLE JUMPED BACK ONTO ROAD AND JUMPED DITCH IN MIDDLE OF INTERSTATE. VEHICLE CRASHED INTO OPPOSITE BANK OF DITCH AT APPROXIMATELY AN 80 DEGREE ANGLE, CRUSHING IN FRONT END FROM MIDDLE OF HOOD OVER TO DRIVERS SIDE OF VEHICLE. AIR BAGS DID NOT DEPLOY. VEHICLE PIVOTED TOWARD PASSENGER SIDE, ROLLED OVER ONTO ROOF AND CAME TO A STOP. THE VEHICLE WAS CONSIDERED A TOTAL LOSS BY INSURANCE. JUDGING BY AMOUNT OF DAMAGE TO FRONT END, THE AIR BAGS SHOULD HAVE DEPLOYED. JEEP WAS CONTACTED AND THEY SENT AN INVESTIGATOR. I CALLED JEEP EARLY ONE MORNING AND THEY STATED THEY DID NOT HAVE ALL THE INFORMATION TO TELL ME WHY THE AIRBAGS FAILED. FIFTEEN MINUTES LATER A JEEP REP. CALLED AND STATED THE AIR BAG SYSTEM IS WORKING PROPERLY AND THEY WERE NOT SUPPOSED TO DEPLOY. HOW DID THEY GET ALL THE INFO NEEDED IN FIFTEEN MINUTES? THE VEHCILE HIT HARD ENOUGH AT THAT ANGLE TO JAR REAR WINDOW ON PASSENGER SIDE LOOSE TO WHERE IT WAS ONLY HANGING ON BY BOTTOM SEAL. I MADE SURE TO TAKE PICTURES SHOWING THE AMOUNT OF DAMAGE TO VEHICLE.
