I am not sure how great the data is but according to carcomplaints.com the issues for the 2016 Subaru Legacy are minimal(however 3 recalls that were repaired). So, as far as I can see (thank goodness for the 10 yr/100,000 warranty on the cvt), the Legacy gets really good reliability ratings and kudos from Consumer Reports,Iseecars, carcomplaints....I mean, other than a bearing here or there/battery, most of the kinks were worked out by 2016 and it really is a hardy beast.

I will say there does seem to be quite a bit of whining/complaining here on this site but not anywhere else(including Edmunds/cars.com). Even autotrader loves the 6th generation Legacy. Oh and JD Power could live without the Legacy...lol. Not sure about real posts vs trolls. Not sure it matters.
I have put about 5,000 in miles a short while, have averaged 32 mpg in western PA and on a long trip averaged 36mpg. 1 oil change(3 years free) and tire rotation. I did have the radio flash update and that did improve the radio. Love the huge gas tank. 1st time subaru owner and I can see why they have a loyal base.
