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 personally use Samsung 50S and RS50. The RS50 or 50XG are the optimal choice in my opinion.
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.
I did the same replacements two weeks ago, it took about a week for the battery to recalibrate, definitely am seeing the improvements now.
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.
Battery didn't outright die but it was weaker starting and with winter coming I didn't want to trust it.
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.
Looks like I'm getting a battery replacement. Very disappointed in Samsung this year.
My Forester is 2021, already replaced the starter and the battery. The current battery starts to feel weak as well.
