I just bought a 2010 SE 4x4 (125k miles, one owner, no reported accidents) and while treating the plastic on the air damn/wind fairing and basket, I noticed these ripples in the rain channel. The extend the entire length of the driver's side and they are also present on the passenger side above the front passenger door. Ive owned both a 2011 and 2015 in the past and do not remember having these. Anybody else have them and if so, do you know what the story is with them?
