Rust undercarriage

Rust on passenger seat rear hinge
I am off of the extended warranty and onto the rust!
Attached are two pictures.
I will start with the rust on the undercarriage. Do you feel this is a normal amount of rust for a 2016 CPO RDX?
The other picture is of the rear hinge anchoring the front passenger seat. My question here, is why would there be rust on this hinge? Prior to purchasing the RDX, I reviewed all the history, including the Carfax, and there was no indication that the car was in an accident or a flood.
I am sorry that I do not know how to resize the pictures.
