My 2016 front right sensor goes off all the time when thwre nothing in from of the truck. I took it in already and they said they can duplicate it. I took a few videos to share with them. It's almost like they are pointed too low and that react to the road.

So it does it in 4H too. So it's definitely a transfer case related issue. I'll have the dealer look it. Since no one else is experiencing slight vibrations with 4WD engaged. Kind of odd, since I have no vibrations with my truck at all (except AFM related stuff) in 2WD. I can cruise at all speeds and it's butter smooth. No wheel/tire issues. I'm kind of surprised no one else have any kind of slight vibrations with 4WD engaged. I guess the plus side is that I dont really drive in 4WD very often.

Is that something I can do or the dealer?

I've been looking and haven't found any similar thread. My 2016 A/T truck is very smooth across the board at all speeds in 2WD mode. So we had the blizzard here in the northeast last week and as the snow has been melting and refreezing, I've been driving in Auto mode. I've started noticing that if I give it medium to heavy throttle, the truck vibrates from 40-50 mph. It's smooth up to to 39 mph, and smooth once I'm up to normal speeds of 65-75 mph. It only happens from 40-50 mph and in Auto 4WD. And never on slow acceleration such as traffic light to traffic light. Anyone else have this? Is this normal?

Oh...I also added 4 more Gear-On bed hooks and ordered a trailer hitch cover in generic black.

Here he is. Since purchase I've added the GMC mudflaps, the GM center console organizer, the driver side A-pillar handle, the GMC chrome exhaust tip, the GM rear underseat storage bin. Also bought a wireless charging back for my Samsung; pretty neat feature. Getting the front windows tinted on Wednesday. My Undercover Flex tonneau cover arrives Friday.
