My old pickups never made half the noises my new ones make. Only one small difference I see from the old ones vs. the new ones. That little sticker inside the door on the old ones says made in Japan. New ones say Cali. USA. :)
Thats bull. They should fix it. No reason why a brand new truck should grind or humm or vibrate for any reason unless something is wrong. CAll toyota tell them whats going on. Take it to another dealership if you have to. An in worse case fix it yourself and let toyota know that you fixed it...
