Default Rattling on Driver's Side 2015 RCF

Anyone experience a rattling noise on either driver or passenger side? The rattle seems to be coming from either the window itself or from what I could find online the window not fully engaging with the rubber trim causing the window to rattle when driving.

Rattle is consistent, becomes more pronounced in rougher roads but overall loud enough to be incredibly annoying. Was wondering if anyone experienced and found a remedy?

Mine is tight and rigid as a button. Everything is very snug even on bumpy roads, only the suspension stiffness that bobbles the head and nothing else. I think the mechanism that lowers the window about 1 inch when you open the door might not be going back up all the way when you close the door. Does that mechanism work (open the door and the window slides 1 inch or so lower)? It should roll back up as soon as you close the door. See if there is gap between the window and the frame.

I had to have a front strut replaced around 40K miles. It made a rattling sound over bumps. I have never had any noise from the windows. I have read others have had to replace the sunroof gasket for rattling.

Uhhh, I’ve been living with a buzz from the driver door near my elbow when the Leviston system’s bass hits. I thought maybe something fell into the ambient light but it was not. If I push on the door with my elbow it stops.

I have the same rattle. I only hear it randomly on rough roads as well. I initially thought it was coming from the window, but if I wedge my fingers in the gap between the driver's side door and the end of the dash, more often than not, it goes away. I should look for a piece of black rubber thin enough to fit there with adhesive on one side to see if it makes the rattle go away.

Thanks for all the inputs and suggestions - the rattle goes away temporarily when I aggressively slam the door shut. Am too guessing the top of the window isn't fully engaging with the rubber trim as 05RollaXRS suggested.

Will see if creating the wedge makes the rattle go away!

I had two '15 RCF's and both did this. I found it to be, on mine at least, was the vertical part of the window behind your left ear where the window met the thick factory weather strip. I heard it all the time. I place a top to bottom piece of weather strip the entire vertical height and trimmed it to match the black window paint (I dont know what else to call it.) The thickness was very thin, 1/16 thick, the width was about 1/2 inch. It was soft touch and it solved the problem.

Hope this helps...
