Thanks for the update!
Fiberglass and metals have different expansion/contraction ratios. Doesn't mean they are bad or junk, but it does require some consideration to how it is constructed and what type of sealant/caulking is used.
As I mentioned before, manufacturer pretty much flubbed the build by turning the wheel well metal up on the outside of the siding.
So basically it is a manufacturing design flaw.
Manufacturer should have turned down the wheel well sheet metal, then ran the siding down to cover the turned down sheet metal. Then all that would be needed is a dab of caulking between the inside of the siding and the sheet metal.
Think of like shingles on a roof, the shingle on top of the lower shingle sheds water over the top of the lower shingle..
In your case, they installed it backwards with the top of the lower shingle on top of the bottom of the upper shingle..
