Exterior Rearview Mirror problems of the 2020 Honda Accord

Driving slowly down a residential street during daylight hours and suddenly there was a loud noise and the passenger side side view mirror exploded. There wasn’t an accident of any kind - the car had not come inti contact with anything and there was no other damage except the actual glass part of the mirror was completely gone. There were no scratches or other damage to the rest of the mirror assembly or the car and no evidence that anyone had thrown anything at the car. The car was driven immediately to the Honda dealer and they insisted that there must have been an accident and refused to cover the damage. A brief internet search revealed others with the same make and model had experienced the exact same thing. I strongly believe this is a manufacturing defect and it is a safety issue because the sound of the explosion was startling and there was broken glass flying around and now the car side view mirror is missing.
