Welcome to the "club of clunkers" This was reported by several members, I am one of them.

I have a 2010 which I bought new in 2011 with exactly the same symptoms as you described. Last year I bought a used 2009. She is nor "clunking". The 2010 tried to teach her how but did not succeed as yet, lol.
