I opened the liftgate the other day and heard a clunk. Turns out the whole thing is a misaligned from the factory. The top left corner was catching against the body, and the paint is gone now in that spot. Its not bent or crooked due to damage. This is 100% factory. The door is flush against the body the whole left side all the way down, and the gap on the right side is about double what you would expect.

This could explain the liftgate open warning light we got a few times. We just figured we didn't close it hard enough.
Going to the dealer today to see what can be done.
