    Hey all,

    I see lots of posts but they are all 2015 - 2018 for the buffeting noise. My Hoe is driving me insane and two dealers told me they cannot hear it!

    Any advice on next steps or if there is a TSB about it for the 19?

    TIA - hope to get a smooth quiet ride soon!

    tell them to go through the car wash dryer section and hear it for themselves.

    bad news, they still dont really have a clue how to fix it

    it effects '15-'20
    have to imagine the '21 & up , may have it still or reduced.


    my '15 never had this issue.... so its very hit or miss

    we had a 15 LTZ 2wd that had it start after hitting a deer. They had to take the headliner down and glue the roof rails to the roof.

    Knock on wood neither our 19 or 20 both 4wd have it.

    Go to the fuel economy info page... look at the bottom left and see if you only hear the noice when the engine goes into v4 mode... if that’s the case it’s normal and nothing can be done unless you get an aftermarket tune to turn it off which is available

    can put it in Manual & drive 1 gear down... if you dont want to tune it or get a Range device or change cam, to keep it out of v4
