They found service notes regarding a "rattling door" and that requires a replacement door as the inside framing delaminated, but mine doesn't rattle, it just vibrates like crazy at highway speeds. It's like wind just catches it at the right angle and the door starts massaging my left leg.
Strange that the issue disappeared, did Service happen to adjust doors for any reason in the meantime? I have the same issue, they want to replace the door, but it that seems a bit extensive, it's such a big job my Service center has to contract it out to a local body shop as it's quite involved.
Do you have any pictures of what your old wiper was doing to windshield? I got a "revised" blade too but it was no better.... I wonder if some people are complaining about the new blade... Can you show a picture of your old windshield streaks? Please :)
