One possibility is that there aren't as many 13's out there with lots of miles yet.
But you are right, first-year production usually yeilds more problems.
My concearn is that they may be so jazzed about sales figures that qc could be slipping.
Hopefully for consumers the kinks have been worked out of the 13's.
The oil consumption, I doubt has been "fixed" as no one seems to know what its coming from, and its affected random fb and fa engines starting with the 11 forester.
