I don't know what you're missing but I could not recreate your problem.
I configured the setup you described, used the three summary addresses
you described, and had the three summary routes in the IGRP domain. No
static routes. All routers could ping all interfaces. Attached are the
router configurations and the routing tables. Let me know the
difference between your configurations and the attached.
Another way to insert a default route into IGRP is with the ip
default-network command.
