Most likely the autorouter grid setting is too coarse.  Try making it half
the pin pitch of the SMD device, although this may make is significantly
slower.  I've had some jobs that took a few hours to autoroute due to fine
pitch SMD, but it did a nice job in the end.

By the way, I always use more optimization passes than the default setup
does.  With the right parameters in 8 optimization passes you can get a
significant reduction in vias and traces that aren't restricted to
horizontal or vertical.
