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.
