I just experienced the same issue and there is a bit of a gap between the antenna & roof. What happened to yours ... did a plastic piece inside break or was it just a simple tighten of the nut? I do not ant to take it all apart to find out I need to buy new parts and have to put it all together to take it apart again when I have the parts. What happened with your repair?Can anyone help me with the instructions on replacement of the roof antenna on. 2018 MDX?
My garage door did not go all the way up and hit the antenna and made loose. Small gap. May just need retighten the nut.
