car makes very loud idles wheather i am just at a stand still or driving..

brought it into dealership maybe 6 times over the past year.. They changed updated the keyfob, updated firmware on car, change spark plugs, etc.

now its in the shop again, and this time they going to swamp the timing chain..

anybody else have this problem?
