    I still haven't had a chance to take my car back to the dealership. I do periodically check back on this forum for any new information regarding the clunking issue. After reading OKC_CX9 post, I decided to pop my hood and noticed that two plastic piece were rubbing against each other on the driver side of the cowl area. I put a piece of sink rubber gasket in between the two plastic, I think that took care of my clunking issue, at least I hope so. I did test drive around few speed bumps in my area, so far so good, no clunking noise. I hope this completely solved my issue, I will report back when I drive the car more and see if the noise if still there.[IMG][/IMG][IMG][/IMG]

    James, it appears that either a piece (that you replaced with your temporary rubber bit) is missing, or something is allowing those parts to move more than was intended. If you find out, please let us all know.

    Thank YOU!
