Plastic trim coming loose

[logic_guy]

So i've noticed in the last few days, my rear passengers arch has got further and further away from the body.

Is the plastic for the trim cheap and distorts under the heat and cold? I'm guessing i'd need to replace the clips?

Yeah just the clips chap replace all of them and if you fancy it bond the panel on as well

The clips are 14p each from a dealer.
