I bought this car in October of 2015. In November we went on a road trip and among other issues I noticed the cruise control doesn't function properly. When you are cruising at highway speeds and climb a hill, it'll down shift and the RPMs will shoot up to 5,000 (this is understandable it is a 2.4L engine) however, my issues is coming down hill. No matter the speed, no matter the distance as we are coming down hill the vehicle will not shift again to lower the RPMs. You have to physical dis engage the cruise control, wait for it to shift (when it does it shifts hard) and then re-apply the cruise control. I had a friend follow me in another vehicle told him no matter do not change your cruise control. Normal flat land we would stay an average of 2-3 car lengths, going down hill we would get 7-10 car lengths between each other. So who knows how fast I was actually going.. anyone else have this issue, or any hard shifting transmission issues?

It is making a scraping sound I have changed wheel bearings and c v axler sounds like it is in the transmission what could it be
