Sequoia 2016 noise

Hello everyone. I know it's not a Tundra but at dead end and I hope someone can help me. Given there not many sequoia owners/forums. I am desperate.
I have a brand new 2016 sequoia 5.7l. After break in period, the truck developed a humming/droning sound that is most pronounced at 1600 rpm. I have gone rounds and rounds with toyota and they are claiming it is normal. I have test driven 2 brand new sequoia, 1 brand new tundra and 1 older sequoia. None of them have this noise.
I took it to my small shop trusted mechanic and he said it is a radiator fan clutch issue.
Does that make sense? Any ideas of what it could be?

 

If toyota said it's normal it's probably normal... plus it's under warranty if anything happens it's covered

 

I am not sure what "normal" means. if it is so loud it is driving me crazy, and if 4 other trucks didn't have it, then I am not sure what "normal" means.

I am not concerned about something happening, I just can't drive my brand new $55k truck, it is that annoying.

I respectfully disagree with you that Toyota's word is written in stone. no one knows my truck more than I do. and I can tell you it is not "normal", I am 50 years old and I have been driving trucks since I was 14 in my dad's farm driving his 1977 chevy "custom deluxe". unfortunately I am not a mechanic to figure this one out.

Toyota response is very typical of how we approach things these days. if it is obvious, they will fix it, if not, they will brush it away and tell me I am the problem hoping I will go away. which unfortunately, I might have to do because I have no recourse with them.

I even went back the sales person who sold me the truck, he drove it and within 0.5 mile he said, that does not sound right. then he drove a used 2010 sequoia that he had on the lot. we left the parking lot and promptly turned around and said, I don't need to drive it more, I can tell the difference.
I am awaiting this dealership's service shop to call Toyota and see what happens. I am not optimistic since the special technician is probably the same guy since it is in the same county as the one before.

I was just hoping the gurus in this forum would shed some light on some possible reasons. at this I will pay for the repairs myself, I don't care, I just want to find out what the issue is.
