I just called Toyota Corporate and after explaining my issue with the dashboard, then asked for the VIN and then verified my contact information. I was assigned a case number and told that they would review what might be going on. I then asked if as a 2004 Sienna owner I would be getting contacted to see if I had a problem with the dash (as would all of you as 2004 Sienna owners) and after we all expalined that we had the EXACT SAME problem, they would then issue a recall. She said that yes, theoretically, that was the way it would work. I then promised her I would provide her phone number to this discussion. So here it is.
1-800-331-4331. It will only take a few minutes. Have your VIN ready and try not to get irritated when the "your warranty has expired" line rears its ugly head. I fiugre if enough of us make this call, then MAYBE Toyota will do something.
