was cleaning my car and found there is something weired.
look at the picture 1 inside the tail light. the small reflective plastic felt off its place.
is there any way that i can put it back because it looks that there is kind of clips that holds it in place.
please advice.
the seceond picture is the left which is fine. take a look and compare it

Yes you can fix that, you would have to remove it from the car and heat it up and pull it apart then get some superglue and tac it back in place.

Is your car still under warranty? I would take it to the dealer either way and see if they will replace it for free. Not something you would expect and they may want to see what caused this to happen.
