Owner report 11114422 · 2018-07-29 (July 29, 2018)
I WAS ON THE CAPITAL BELTWAY OUTSIDE WASHINGTON DC GOING ABOUT 60 MPH AND MY SUNROOF SUDDENLY SHATTERED. IT WAS EXTREMELY SCARY BECAUSE IT SOUNDED LIKE A GUN SHOT GOING OFF. IT WAS A VERY HOT DAY, LOW 90S. LUCKILY I HAD JUST CLOSED THE SUN VISOR SO THE GLASS DID NOT POUR DOWN ON ME OR MY PASSENGERS. WHEN WE PULLED OVER, WE FOUND A LARGE HOLE IN THE FRONT PANEL OF THE PANORAMIC SUNROOF AND SHATTERED GLASS SITTING ON THE FABRIC SUN VISOR.THE REMAINING GLASS WAS CRACKLED. I JUST GOT THIS CAR, BRAND NEW, 2 WEEKS AGO AND I KNOW IT HAD BEEN IN A …

Owner report 11479668 · 2022-08-16 (August 16, 2022)

After refilling the car's engine coolant and still getting alerts, I brought the vehicle to the BMW auto shop where it was determined there was an active coolant leak from the hose of the cylinder head expansion tank.
