I reported this incident once already and since then 2 more 2019 For Expedition had the exact same issue. The seatbelt tensioner charge blew up for no reason while vehicle was stopped and running. This is a very dangerous problem as I almost heart attack, I thought I was shot. PLEASE INVESTIGATE THIS AND DON'T WASH IT UNDER THE RUG. TO THIS DAY I'M AFRAID OF DRIVING MY EXPEDITION FO FEAR OF IT HAPPENING AGAIN.
