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.
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
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.
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 Forester is 2021, already replaced the starter and the battery. The current battery starts to feel weak as well.
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.
I will not trust having a Subaru battery in my Subaru cars, I only buy Walmart, Costco or Interstate.
My 2021 with 84k miles was very similar. Even had the auto start fail to restart the car once when it was cold. I just had the battery replaced with the new larger size one and it made a huge difference.
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.
Replaced original battery at 93,000 miles. I live in Detroit. Cold winters. I guess I got lucky.
