I have a 2019 F3L with about 2400 miles on it. Over the weekend I took about a 400 mile ride and about half was on the interstate. Each time I got 72 mph I felt a rough vibration that lasted 30 seconds or so and then it smoothed out. The vibration would come and go during the time I was 72 or faster. I never felt it under 72mph. I’m not on the interstate often so this weekend was the first I noticed it. Has anyone experienced something similar? Is this belt vibration or something else? Any help is appreciated.
