Air bags

8 reports2 crashes
“THIS CAR HAS BEEN WRECKED, DUE TO THE AIRBAG, AND THE TITLE WAS HANDED OVER TO THE INSURANCE COMPANY AND THEY ISSUED US A CHECK FOR SETTLEMENT. THE CAR WAS CONSIDERED A TOTAL LOSS. WE NO LONGER OWN THIS CAR; HOWEVER, WE KEEP GETTING 3 OR 4 POSTCARDS EVERY MONTH NOTIFYING US OF THE RECALL. I HAVE MADE COUNTLESS PHONE CALLS TO GET OUR NAMES REMOVED FROM THE RECALL MAILING LIST, TO NO AVAIL. IT IS EMOTIONALLY DISTRESSING TO ME TO SEE THESE POSTCARDS ARRIVING, REMINDING ME OF THE AUTO ACCIDENT THAT ALMOST CLAIMED MY HUSBAND'S LIFE. OUR RECALL I.D. NUMBER IS KB8-42S. WOULD SOMEONE PLEASE REMOVE US FROM THE MAILING LIST. THE ACCIDENT OCCURED ON 7/18/2018 AND THE AIRBAG EXPLODED, CAUSING HIM TO HIT A TREE HEAD ON. HE WAS AIRLIFTED TO A TRAUMA CENTER AND SPENT OVER A WEEK IN INTENSIVE CARE, FOLLOWED BY SEVERAL SURGERIES AND FOLLOW UP HOSPITAL STAYS. PLEASE, SOMEONE, REMOVE US THE LIST.”
