I had exact same problem. I used clear GOOP glue and it has held it fine. Pulled it out somewhat, put glue behind plastic chrome, duct taped it together, dries overnight.
Dont use a colored epoxy, use a clear glue. GOOP will flex so if the plastic pieces expand in the heat, it can move. An epoxy would be ok, but if the plastic wants to move with temperature change, it could be a problem?
