Cooling is still being ate up. Took to a different dealer for second opinion. No physical leaks dealer put in dye to see if they could find the leak told me to drive it around for a few hundred miles.

This should be a recall no one could find the leak. I brought it to the mechanic and they said nothing was wrong bc they couldn't find the leak ... here it was leaking into my engine and blew a head gasket I can see a lot of us are having these issues
