Clicking tapping noise

I have a 2017 dodge van and noticed only when a
passenger is sitting in the passenger seat that when
I go over bumps or turn right that it makes a
tapping clicking noise which is getting annoying ..
dodge told me it was probably just the seat and
won’t look at it unless I pay a fee for them to
inspect it ... only driven approx 6 months ( new from
dealer) any idea what it could be???
