The default route actually comes from the RA, not DHCPv6. But check your logs for a "NAK" coming from dhcpcd. If you see that, then I'll bet its the same problem that I've been corresponding with a user over IRC about. dhcpcd touches addresses internally, and when it gets a NAK it actually removes the IP address from the interface, which could cause the kernel to remove the default route too. Unfortunately, due to an issue in NetworkManager, it is never notified of this event, and ignores the fact that things changed, and thus doesn't restore the default route. Let me know if you do see "NAK" in your logs...
