My driver’s side mirror spontaneously cracked. There was no damage done to the mirror that would cause this to happen. The mirror was intact when I pulled into my garage. An hour later I left again and the side mirror was cracked top to bottom. It is not difficult to get a non- distorted view out of my driver’s side mirror and I feel it impacts the BSI as well. I have an appointment on 3/20 for inspection at the dealer. There were no issues prior to this happening. My photos show that there are no nicks, scratches or anything around the mirror at all. Also the mirror is not shattered, it’s simply a clean crack down the middle.
