Uhm... There are leaks?

Take the thing to Discount Tire and ask them to check them.

I had one tire on my 2015 Jeep Grand Cherokee losing pressure like that, only not nearly as fast as your wife's Odyssey. I recognized the symptom. Figured it was either a rim or valve stem leak. I was right: Valve stem.

DT diagnosed it and "fixed" it for no charge. (I'm a long-time customer--as in maybe forty years?)

I put "fixed" in quotes because it was corrosion around the valve stem. Any fix is temporary--even when it works. And, even if it does turn out to be permanent, it's only a matter of time before another does it. So, NLT than next year I'll be replacing the rims along with the tires.
