2018 Honda Civic air bags problems

Was in a car accident [XXX] and air never deployed instead a warning starting flashing saying something was wrong with my air . I was in 3 car pile up and terrain truck went under my car and slung it around cause me to hit the bridge and it bent there entire metal frame when u looked under it the doors where not even ànd hatch back was jammed with huge gap between it and the car it cause the front windshield to become detached from the glue holding it in place u could see little shavings of Glass all the way…

On 11/28/2018, I was driving on freeway and the air bag in my car deployed with no reason. I sent the car to the dealer for investigation. The dealer told me that the air bag is deployed because they found a dent on the rear control arm which I found hard to believe. When the air bag deployed, there was no collision, I was driving on freeway, so there is surely no bumps on the road. Even if they found a dent on the car, there is no proof that the dent is made on the same day that the air bag pops up.
