Rusting away..

[Gogogordy]

The corrosion warranty usually specifies "perforation" or "rust through" and Id be surprised if a cursory detailing and touch-up isnt all they do for it at this point.

Given the OP's location, (and judging from the pictures) acccumulated dirt, including what is likely "road salts", aren't helping matters.

Washing your car regularly year-round especially ones that get used in "rust belt" states where they DO salt the roads, and have dirty rain is more important in the winter months for this very reason.

I know it seems silly to wash a car when snow-ice-rain-crappy weather as much as guaranteed, but doing so is actually more a preventative measure than a cosmetic one.

The old saying "a clean car lasts longer" comes to mind.
