A/C Vent won't stay in place
 

Hello everybody, I just joined this forum and it looks like there are a lot of knowledgable folks here. Here's my dilemma. I bought a 2016 Civic EX in August 2016, and promptly broke my back. I still have to walk with a cane, whatever, beats the alternative. However, I don't drive as much and as of today the car only has about 5700 miles on it. I noticed right away that the left center vent would always move up when I get in the car. The first few times, I just figured I had it pointed at the roof, but I'm not that stupid. In summary, it seems to happen when it is hot outside, but I seem to recall that also happens in the winter. Can't say for sure. The car has a black interior. Has anyone else noticed this problem and if so, how was it resolved?
