I have this exact same problem! Did you ever find out how to replace that gasket/seal that is falling out from under the rear lift gate spoiler? I can find tutorials on how to replace the whole spoiler but nowhere does it mention that seal so I can’t find what part it is.Please see attached. What is it and how do I fix it?
Ha! I love it. I don’t know why I didn’t think of that. As long as the stupid spoiler isn’t rattling around, I guess a piece of that rubber gasket won’t be missed. Thanks. I kinda wish there were kits to just remove that spoiler, but it wouldn’t be that easy since that brake light is in there.I cut it off like a circumcision and moved on.
