Took my 19 in for some minor warranty items:
Trailering gives faults on dash about trailer disconnected/trailer connected, and turn signal faults
Mild rattle at cold start for 3-4 min (sounds like wastegate rattle--don't know if they'll be able to do anything about it). It's not phasers.
Sloppy shift into 4th about every 1/20 shifts (guess I'm hoping they'll reflash the TCM)
I asked for a loaner and followed up on it closely, and they got me a loaner. It's a 2021 Explorer limited, and I'm pretty happy with it. It's little 2.3L will go!
