ON 11/21/2020 AT 5:30 PM, WE HAD A CAR CRASH ON A HIGHWAY I-495 (CAPITAL BELTWAY, MD), WE WERE IN OUR CAR (I, MY WIFE, 2 KIDS), WE NOTICED A SUDDEN STOP BY MANY CARS AHEAD OF US IN THE SAME LANE WE WERE IN (LEFT LANE), I PRESSED MY BRAKE AND BEEN ABLE TO AVOID REACHING THE CAR AHEAD OF ME BUT UNFORTUNATELY, THE CAR BEHIND ME WAS VERY FAST WITH NO CONTROL IN THEIR BRAKE THUS, SHE HIT MY CAR FROM THE REAR AND PUSHED ME TO HIT THE FRONT CAR. AFTER WE STOPPED, I WENT OUT TO NOTICE THAT 9 CARS WERE INVOLVED IN THE CRASH. ALTHOUGH IT WAS A BIG AND HARD ACCIDENT, MY CAR'S AIRBAGS DIDN'T DEPLOY, HOWEVER, IT DID OPEN IN MOST OF THE OTHER CARS. DUE TO THE NONDEPLOYMENT OF THE AIRBAG, WE HAD A LOT OF BODY PAINS, WHIPLASHES, AND MY SON WAS HIT IN HIS HEAD (I HAVE AN EMERGENCY INITIAL DIAGNOSTIC REPORT FROM THE HOSPITAL). IN ADDITION, MY CAR EXPERIENCED HUGE DAMAGES FROM BACK AND FRONT, AND EVENTUALLY, IT HAD BEEN TOTALLY UNFIXABLE ACCORDING TO THE INSPECTION FROM THE COLLISION TECHNICIAN. I HAD CONTACTED THE CAR MANUFACTURER (NISSAN) TO OPEN A CASE, BUT THEY DIDN'T CONSIDER THE RISK THAT WE EXPOSED BY NOT DEPLOYING THE AIRBAGS AND THEY IGNORE THAT THEY ARE HAVING ANY PROBLEMS REGARDING THIS ISSUE AND THEY JUSTIFIED THIS INCIDENT BY SAYING THAT AS LONG AS THE CAR BEEN HIT BY THE REAR THE AIRBAG WILL NOT BE DEPLOYED REGARDLESS OF THE HIT STRENGTH.
