Battery OEM Mazda or OEM Subaru

I had to replace the battery on a 2016 Crosstrek this summer and, in retrospect, missed a bunch of warning signs before it finally wouldn’t start: slow cranking, occasional extra crank needed, flickering dash lights, and generally dim interior lights.

Have a 2020 Touring XT. Battery went bad after 5 years so that was normal. No problems other normal wear and tear, tires and brakes.

2014 Mazda 3 with 322,000 kms, it's doing fine. I'm still on original engine, transmission and starter. I use it almost daily in traffic. The only problem is that the battery is slightly more costly than a standard one, which offsets the miniscule fuel savings you're getting from the system

with the auto start/stop eliminator installed after 1 year of ownership (using the auto start/stop feature the first 6 months and manually disabling it the last 6 months), my 2019’s battery lasted 5 years and 160k km before it started feeling weak and was replaced as a precaution.

Very unlikely to be the starter, though anything is possible. I'd put money on the battery being weak though. Voltage isn't the end all be all, you need to know about the cranking amps.

I bought my wrx brand new in 2015, the battery lasted two years and was replaced at the dealership. That second battery lasted two years and I went back for them to replace it and said that they wouldn\u2019t because it was already replaced under warranty. She told me they would replace it for something like $160, I said \n\n\u201cLook lady the first battery lasted two years and the second lasted two years, I\u2019m not spending my money on your junk batteries.\u201d

21 Outback. Battery issues - I’m on my fourth battery since buying it. Have had issues with door seals leaking, but those were fixed easily under warranty. Definitely can confirm the assembly quality - we had to test drive quite a few before getting one that didn’t rattle on every bump we hit.

My brother and I both have/had 6 speed 2015 Mazda3 (me the hatchback, him the sedan), and both of us had terrible issues with the Mazda brand batteries.

My Forester is 2021, already replaced the starter and the battery. The current battery starts to feel weak as well.

I will not trust having a Subaru battery in my Subaru cars, I only buy Walmart, Costco or Interstate.
