2017 Renegade, 1.4 turbo, 6 speed manual. 42k miles. I have owned this vehicle for 3 years. As many and myself have described, like clockwork noise starts at 38 mph and goes away at 43 mph. I recently took a 900 mile trip/2 day trip with this vehicle. On the highway at speed, (65-70), this disturbing noise would appear for 2-3 seconds and then go away. It didn't happen often. Over 900 miles it may have done it 4-5 times. I have no idea what may be engaging or disengaging to cause this or why. I thought I heard this noise before at speed but it happens so infrequently I thought it may have been a rough road patch. This trip showed it to be otherwise.
