Hi all. Just traded in my 2013 S85 for a 2017 S75. I’m hearing a highway drone between 81-85 mph in my new Model S. My 2013 had DU replaced a few times for drone noise between 76-80 mph, and it was never completely quiet after each DU change, and it was always in that same speed range. I love the new car, as I loved the previous, but I wonder if it’s just normal for all DUs to have this bit of noise, in a specific speed range, which is not the same in all Model S. I’m glad at least in this car it’s in a speed range I don’t drive in too much. Anyone else who has driven several Model S have thoughts?
