Last night it was pretty chilly out and noticed when I remote started out new Expedition that I could see a small amount of exhaust smoke coming from under the vehicle. Anyone else notice this? Wondering if I should have the dealership take a look at it or is this normal.

Picture covers it but was the exhaust coming out of a join? If yes have them check it out. Might just be a loose fitting

No it's coming out of tiny holes in the muffler.
I’d have them check it out then. The muffler has 2 inlets and 2 outlets. It should not leak exhaust from “tiny holes”. I checked mine and no such leak. Sometimes water condensation will steam off, but that goes away in a few minutes.

My wife's '21 Navigator has the same thing. Believe they're just small weep holes drilled to prevent condensation from building in the mufflers and creating rust. Hasn't caused a problem yet.

Its weep holes to drain the water from moisture condensation. My wife Navigator had these as well. Designed like that so it doesn't rust out from water trap.
