I have an 08 journey. Yesterday I was driving and I noticed a clicking sound as if it were behind my dash. I noticed as I accelerated the noise would also increase in speed, and as I would slow down, it as well would slow down. I couldn't find the issue, it doesn't happen all the time but I do notice when it does. Sorry I'm not good at explaining things but if anyone has had a similar issue please share your experience with this problem. I will try to post a video tomorrow.

 

Are you running your AC while this is happening. I hear a quiet whine or whistle upon acel/decel when running my AC.

 

a rock wedged in one of the front tires?

 

Could be your brake pad wear feeler clip, if the pads are down to the wear clip it may be making the noise you describe.
