NHTSA Complaint #11488801 — 2018 SUBARU OUTBACK

I bought a 2018 Subaru outback in January of 2022 from a Subaru dealership. Approximately 3 months after purchase the car battery died suddenly with no prior warning, so I jumped it, it started fine and I drove it to work. When I took my lunch break 3 hours later, my car was dead again. I jumped it, it stated fine and I drove home. same thing happened when I tried to go back into work, and when I tried to leave work for the day. During my lunch break on the way into work the dash light and display screen shut off completely while I was driving this happened a second time when i left work on the way to an auto shop. At the auto shop they ran diagnostic on the battery and declared it dead, unable to hold a charge any longer. I then payed 250$ bought a brand new battery and got that installed. Here I am 6 months later and I am having the same issues with the battery. This is a safety issue what am I to do if the battery dies while I'm driving and leaves me stranded in the winter.
