Tonight I was rear ended by a woman in an SUV, who's brakes did not work in her durango, she said. There were no skid marks indicating an attempted stop. Her impact on my vehicle was severe. Police officer guessed she was going 40 mph when she hit my car. My car was shoved forward into the car in front of mine, that car then hit the car in front of it. There were 3 cars, mine last in line, sitting at a red light. We were all stopped. Then there was a 4th car that hit mine from behind. The matter im reporting is that the airbags in my Hyundai Sonata SE 2011 car did not deploy when I then hit the car in front of me. The impact was great enough to cause that car to then hit another car and that caused a crack in the radiator of the car in front of mine. Also, after I hit that car in front of me, I then bounced back about 10 feet. More evidence of impact. Why no airbags? I did not see very much damage to the front of my car nor the back of the car that was directly in front of mine, while the back of my car was bad enough that I expect to be told it is not repairable.. im reporting just in case you receive any other reports indicating there is something faulty concerning airbags in the Hyundai. I know airbags are not to deploy in rear end collision but since I then hit another car frontally, I would think the airbags would deploy. My husband was in the passenger, front seat and in order to brace himself, he put his hand up at the windshield. The glass was broken in an area the size of a cantaloupe from the impact against his hand. Im thinking the impact must have been moderate to severe. On the up side, my Sonata took that hit and sustained the damage to the outside and up into the air at the trunk rather than into the cab of the car. My father and son were in the backseat and were not killed, I think because the car is a good, safe vehicle in a crash.
