I have never measured that wide. I have seen multiple peaks and dips, most well within the 2.0:1 SWR range - on my original Qv4k.

I do not know what is going on, but I think the trunk mount is a compromise location that begs for losses, but you see the graph.
My only question is more academic than diagnostic, but are you using a 1/2 wave jumper that is around 18', or is it an electrical 1/2 wve jumper cut for coax VF?
