I have a 2013 Ram Express 4x4. I noticed on my 50mile commute into work a couple of weeks ago that there was a odd ever so slight rattle sound coming from the driver side corner of the vehicle up by the dash/windshield. I turned radio off and started pushing on the dash an smacked some areas around it while driving with no luck in changing the sound or getting it to stop. I have noticed it in town driving too as well. Bumps etc don't change it or make it happen from my experience so far. Mainly notice it when im on the highway with cruise on. Anyone else have this issue too? Its ticking me off, Truck has 8700miles.
