2017 cl21RBS fender cracked

[MrSmith]

How do I go about replacing my fender. My fender cracked from extreme cold presumably, nothing hit it just cracked and broken in four places. Is this covered under the two-year warranty.  Only the one on the  door side cracked. The one underneath the slide is fine. Has anybody else experienced this on any type of travel trailer or fifth wheel.  Can use some help. Thank you Mr Smith
