We were making a left turn, and a SUV ran the red light across the street and ran through the intersection hitting us broadside at about 45 mph. We were traveling at about. 20-30 mph as we were going to the freeway onramp and had to get to speed. The SUV impact was by the front passenger side tire or just after. The impact was hard enough to bend the subframe to the left. The side air bags did not inflate. We have always had issues with the child safety sensor in the front passenger seat, could that have been the reason? The passenger in the seat was about 105 -110 lbs. and hit the door panel and glass as a result of the air bags no deploying. The hit was bad enough it killed the engine and the frame damage further disabled it.
