The problem of warped rotors is not considered a safety problem. Inconvenient and uncomfortable yes but not a safety problem. Also the causes of warped rotor are not considered a manufactures defects. Consider that there are more user of early Tundra's out there that have never had a problem then those who have. Also consider that this, it is not a Tundra only problem but most manufactures have some model that has annoying pulsation problems if not most.
Engineers point the finder solely at the owner, and the mechanics servicing the vehicles. Not torquing the lug nut is the number one cause. Poor driving habits, and marching run out into rotor during service the next big contributes.
Toyota did some engendering changes to lessen the probabilities of the problem reoccurring. Most manufactures don't go this far. If your under warranty they have fixed this free of charge, mostly to the original owners. If your not the original owner suck it up and get it fixed yourself. I have proved good instructions and a way to do this at a minimum cost. Just do it. Toyota has gone be on the call of duty on this, now its up to you.
