I just purchased 2020 Ford F150 XLT 3.5L v6 twin turbo. Mileage 61,300. I was driving xway on cruise around 76 mph. I heard a sound that it sounded like hail on windshield. Or possibly driving through stones. I had to turn off radio and open a window to hear better. When I took it off cruise I maintained same speed. As soon as I backed off it stopped.

I did not put it back on cruise (was going to Wisconsin). I had it happen a second time about an hour later. Sone thing. Once I backed off speed it stopped.

I have looked all over to see if anyone had the same problem and what it could be. Nothing.

I have 30 day warranty with dealer so I would like to go talk to turn and know what I think it is. I also still have 2 years in power train warranty.
