ON 4/10/2021 AROUND 10:45 AM I WAS ON EAST INDEPNDANCE BLVD AT A RED LIGHT. AS I PROCEEDED TO DRIVE MY FRONT PANORAMIC SUNROOF BLEW OUT. AS A RETIRED NAVY VET I THOUGHT I WAS GETTING SHOT AT AND SLOWED THE CAR DOWN MAINTAIN COURSE AND REALIZED THE AIR RUSSHING FROM MY SUNROOF. ON THIS DAY I ALREADY HAD A SCHEDULED MAINTAINCE AT THE BMW DEALSERSHIP. I PROCEEDED TO PULL IN AND THE NOTICE I WAS REALLY FRANTICALLY ALERT SHOWED THEM THE SUNROOF AND EXPLAINED. THEY CAN'T FIGURE OUT HOW THAT OCCURED. THE VEHICLE IS A 2017 BMW XI DRIVE WITH ONLY 22000 MILES ROUGHLY AND I ONLY HAD THE VEHICLE SINCE AUGUST 2020. I'M HOPING BMY PAYS FOR THIS AND NOT HIT MY INSURANCE. I COULD OF CAUSED SOME SERIOUS INJURIES IF I WASN'T FOCUSED DUE TO MY MILITARY TRAINING. I FAILED TO TAKE PICTURES OF THE GLASS. THE VEHICLE IS CURRENTLY AT 6550 E INDEPENDENCE BLVD CHARLOTTE N.C HENDRICK BMW
