I have an 05' SR5 and have also heard nothing. My neighbor has an 06' and got a recall notice last week. However, I did get the following notice today:
SSC 70A - 2003 THROUGH MID-2005 TUNDRA ACCESS CAB CHILD RESTRAINT ANCHORAGE SYSTEMS NON-COMPLIANCE RECALL. Doubt if I'll follow up on this one.
P.S. You might want to move this to the Gen I Tundra forum as none of these people on the 07' forun give a crap about us "old" Tundra owners.
