Attempted to restart vehicle 15 minutes later and it would not start (just buzzed). Called aaa for a jump start. Was informed the battery was at 10. 2v and there was no problem with the alternator.

Several times our 2019 Subaru Ascent battery has drained down to low levels requiring jump starts. This last time was this winter and -15 degrees outside and was very dangerous for her. The alternator does not seem able to keep up with the load. I have heard of many other people having this problem. It sat overnight on both occasions.
