Mine is in the shop right now getting fixed. Almost in the same exact spot as yours. Also starting to get a spot on the driver door hinge. Had 45,000 miles on it so dealership took care of it.
My daughters 2020 JL had corrosion on all 4 doors and the tailgate. All at the hinges. She had over 50k miles so dealership wouldn't warranty it. Took it to a body shop and had it repaired about 3 weeks ago. Was washing it this past weekend and noticed some bubbling on the edge of the hood.
