I'm most suspecting fuel injector failure - separation at the plastic/metal
junction. That can occur at any age and mileage, often shows up when cold
and may stop leaking when warm, and I've seen quite a few in my time...
including the one that set my Nissan on fire before I could put the new
injector in. On a nearly new car the possibility of a construction defect
can't be discounted either; that is why the warranty exists. I am not
advocating a witch hunt, just due diligence for something that can easily
send the car up in flames.

Personally, I would feel less silly looking for a leak than I would looking
at the charred remains and trying to answer the question, "why didn't you
check it out?" To each their own.

Mike
