My sunroof exploded while driving on the hwy 69 in houston, tx. it was a clear sunny day. no heavy duty vehicles were around me, nor did anything hit my sunroof. it exploded from inside out. i thought someone had fired a gun because that's what it sounded like. i had to call for assistance because i was to frantic to drive or do anything. i am so nervous to drive that vehicle. it was a blessing i didn't hit another vehicle. they want me to pay thousands of dollars out of my pocket or file the repairs on my insurance, bmw need to take responsibility..
