Tire replacement

What is your question?

I bought the car 2 weeks ago. Yesterday, 01/18/2021 I went to leave for work and noticed my front right tire was flat. I was able to change the tire and put the spare on, but could not find a hole in the tire that was flat. And I don't understand what could have caused the flat. I'm still under 90 day warranty.

What makes this problem better or worse?

Replacement of tire.

How long has your 2017 Nissan Versa had this problem?

2 days.
