Battery Panasonic or OEM Subaru

I only just replaced the Subaru branded battery a couple weeks ago with another Subaru battery. It comes with a 30 month warranty and supposed to have a 55 lifespan.

Yeah they use undersized batteries, but just buy a good one and that's the end of it. my 2019 Legacy had is original battery after 4 years when I traded it in.

Yes. Subaru batteries are hot garbage. Go third party all day. I stand by any AGM I can pick up at Autozone, since they stand behind the batteries they sell.

Panasonic Eneloops for me all the way. Bit of an initial investment, but they work so well they're all I buy now for anything that needs batteries. They even kept my Pix running for almost 10 days!

Any tips or advice before I fork out money for a new battery? I have some anxiety hoping its not the alternator dying, or less likely the starter. All things point to a slowly dying battery but I want a second opinion.

It's a known issue that Subaru batteries fail much too early. Subaru began warranting great numbers of them a few years ago.... And they kept using "The same faulty batteries"!!! ...and they still are.

Could be worse ... I bought a new 24 OB and within 3 months, the battery was replaced. Love the car, but crap batteries

I had this happen in my 2020 outback around 37k miles. Dead battery was the culprit. Fortunately I shut off all my electronics and lights and it had just enough power to get it to restart. I got the battery replaced by Subaru under the extended 5 year warranty from a settlement for premature battery failure. It failed right after my 36k service at the dealer I think the car was about 4 years old at the time.

This happened to me during rush hour on a busy street! 2020 Legacy, they told me it was a known issue with the battery and replaced it for free. It was an incredibly stressful morning though.

I had this problem with my 2019 Forester in stop and go traffic on the Dallas North Tollway. I was able to force the car into park and shut it off and back on manually, and this happened about a half dozen more times before my dealer finally admitted that there was a class action on those batteries. I’ve since had it replaced two additional times under a labor warranty. Like I guess it’s fine because it’s free, but very annoying that I bought a Subaru for reliability and I’m in the shop at least every 9 months for a new battery.
