Hi Jesse - welcome to the forum!
I haven't seen any reports of engine issues around here for a long time. Kind of suggests the problem has been addressed by Nissan in manufacturing, doesn't it?
One thing I would do is check out the U.S. based Versa forum.
Both the Versa sedan and Note use the exact same hr16de engine as the Micra and are made in the same factory, but those models sell in the thousands per month in the States vs. hundreds of Micras per month in Canada. So if there are still problems with some of the motors, you'd think people would be talking about it there, right?

If you do check that out, let us know what you find (or don't find).
Darin
