So I had the OEM (at least I think OEM - car was bought used so I don't recall for sure) starter go out on me at about 70k miles about a year ago in july. I replaced it with this NAPA remanufactured one
https://www.napaonline.com/en/p/RAY2446921?impressionRank=1 (interestingly napa's website search shows that part as being guaranteed compatible with the 2016 forester but when clicking thru to the product page it says it doesn't fit - hopefully a website bug) and it has been working well.
However just in the past couple days I had issues with the car occasionally not starting - no loud grinding noise just the classic clicking noise - almost got stranded but luckily was able to tap on the starter and get it to work and get home. So I immediately head to napa and swap out this <1yr starter AGAIN. I mount it up and on first start it works, second start it gives a loud grinding sound. So I pull it apart, look at the starter teeth, and attempt to look at the flex plate teeth with a camera - as best as I could tell they all look okay tho hard to say for sure.
Put it all back together again and notice that when the issue happens, if I manually turn the crankshaft a little the car will start backup fine usually. This sounds a lot like bald spots and/or warped flex plate / flywheel. Is this a common issue on these foresters? Is the non-oem starter a possible issue/culprit?
I know that recently these cars have been extended to 100k/10yr warranty on the CVT - is the flexplate covered under this? Thanks!
