Brake Disc Pads problems of the 2012 Toyota RAV4

I started having problems 04/06/2015 with my brakes grinding and vibrating the front of my 2012 rav 4. I took it in to the dealership and they put new brake pads and resurfaced the front rotors. 42,968 miles on the car. . I was told these new brake pads had a life time warranty on them. . Again Dec. 2016 I started having the same issues so I had to take the rav 4 back in for service and I was told that the brake warranty would not cover the brakes until the brake pads are worn down more. I can not drive a car with my brakes grinding and vibrating the front end of my car when I use the brakes. The brakes are grinding down into the rotors because I was told the rotors where blue. . Which means they are hot. I'm not a mechanic but these pads I'm being told are to hard and they are grinding into the rotors. I was to hear back from the Toyota garage because they where to order these new type pads for my Rav4. I waited a week and never heard back from the garage. So I took the SUV to another repair service to have these brakes and rotors replaced. . The grinding and vibrating has stopped. And I feel safe to now drive my rav 4. . When your having grinding // vibrating of the brakes on your car I don't believe that's a safe way to continue to drive a vehicle. . I didn't even have to drive over 35 miles an hour for this grinding// vibrating to start. It would only happen 50-60% of the time I would use my brakes. . But that's 50-60% of the time to much. The brakes on a vehicle are very important. I made this repair garage give me the brake pads and the rotors. So I did keep them. . I'm not going to be the accident that takes my life "then there"s a recall" on these faulty brake pads. . Being to hard and grinding into the rotors. This is my 5th Toyota and my 3rd Rav4. So I know what they should be driving like. And I never had any of my brakes ever replaced prior to these. .
