I don’t know how you get paid, if it’s by job done etc but I am an “electrical maintainer” and if my boss/supervisor/operator/customer doesn’t agree with my diagnosis and tells me to keep looking- hey you got it!! As long as I’m safe I’ll check everything, even if it has nothing to do with the issue! I’ll replace things three times over again!!! I give a shit! I get paid by the hour tho.
I’d be checking tire pressure, lug nuts, trunk integrity, door gaskets, whatever!
as long as your getting paid and it’s safely.
