Well, I threw in the towel and gave up the Cadenza. After many failed attempts to find/correct the vibrations I was getting in the car and steering wheel I cut my losses and traded it in.
I have a complete set of Weather Tech floor/trunk liner for sale.
I would like to get $225 shipped for the set (front/back/trunk) (midwest/ East coast area) further west I will cover most of the shipping, submit zip code to verify my offer.
