Noticed it already with only 26 miles now on car . It dies sound like a loose wrench in trunk. Having said all this I am at this stage not overly unhappy . Car is comfortable , not harsh and tire noise is nearly unnoticeable . I have 19 wheels. I will report back in a few days. Let's however work to get a financial resolution on seat mis-representation.
Racer10 mentioned in another thread his 2013 had the sound. I am hopeful to get delivery of mine this Saturday (now been on a truck for over a week) and the highway from my dealer will be the true test. There are several make shift patches from the road buckling so driving the new beast home on that I should know pretty quick if there will be a clunk in my trunk...
