Thanks for the thoughtful post. From my perspective, I would very much like to hear about any root causes. As a low mileage driver, I'm concerned about the long term possibility of failure. I'm on the clock instead of the odometer as far as my warranty goes.Should we be informed as to what the issue is? I’m sure this will be a fun topic of debate but it is really up to Subaru if they want it known. Personally as an engineer I would like to know what the root cause is but I mainly just want it fixed right.
At a first cut, I'd ask, "are problems more or less likely to arise as you add more mileage." If it's a matter of statistics (i.e., you are unlucky enough to get a "bad" transmission and you are otherwise fine), then problems are less likely over time. Unless the root cause is related to some kind of engine wear, that is.
