NHTSA Complaint #11439867 — 2020 SUBARU ASCENT

Several times my 2020 Subaru Ascent has failed to start and required a jump. I have taken my vehicle into the Subaru dealers 3 times for this problem. Every time they tell me something was left on that drained the battery when the vehicle was turned off. One time they replaced the battery but same issue occurred after the battery was replaced. Another time they replaced the radio but same problem occurred after replacing with a new radio. The last time they told me the WiFi was turned on. We don't even have a Wifi account for this vehicle which is needed to use the WiFi. Each time the dealers reset electrical components and computer chips they said needed to be reset. This vehicle is a daily driver so does not sit long between starts. I brought the vehicle in October of 2020 when it had 5K miles on it and to date only has 16K now. Now I have to purchase and carry a portable vehicle jump starter as this vehicle's battery is not reliable. I have read that other owner's have the same problem. Why can this not be fixed/resolved without costly repairs to the owner. I am worried that when the Dealer warranty runs out, I am going to face unnecessary costly repairs. Please assist and advise. Thanks.
