Update:
Dealer will not cover the emblems ooze. They had someone come look at it (the same detail guy i visited) and they determined that something indeed has reacted to or had soaked into the 3M tape and caused this to happen. But it is not the tape degrading, it still has a "good grip on the body panel". The consensus is that when i went into a drive though car wash, the soap (with acid or something) didn't get washed off my tailgate all the way. This caused it to sit on top of the emblems or soak the 3M tape. Then when the next rain came it created this problem i have now. this is also why it is coming out of the tailgate handle. the handle doesn't have 3M tape, therefore it has to be the substance from the car wash or acid rain.
Overall, i am fine with this outcome. the service guy i worked with was great. he did all he could. i understand why it isn't covered. It really isn't a big deal. i had planed on taking the emblems off and having the truck professionally detailed.
But now i am waiting for the other reason i took it into the dealer. my windshield cowl pieces are coming apart. you can rub your finger on them and the rubber comes off and it degrading. i think these should be covered for sure. the pics are below.
