Want this documented as it was not previously back in 2022 when the glass shattered the first time. A very cold January day in 2022. Used auto start and defroster. Came out of work whole back window was shattered. Got in vehicle shut door glass fell in and went everywhere. Drove home with giant whole in back window about 8 miles and immediately put vehicle in garage. Called Acura Customer Relations was informed they have never heard of this happening received a case#. Heard nothing after and NEVER was notified of any TSBs. Both times vehicle was under warranty/extended warranty.
