2012 ford edge shutting of due to wiring?

So I bought a car Saturday, 2012 Ford Edge, it was
running fine, then completely shut off on the
highway, screens not working, but lights, charger
port were working. Car wouldn’t turn over, I got it
back today from the dealership, they said it was
due to some wires under the driver seat causing it
that we’re hanging and got cut when I moved the
seat 30 minutes prior to leaving the dealership, I
don’t think there should be any wires causing the
car to not even turn over. Can someone tell me if
this is true or not? I got it back today but feel like
they just put a bandaid on it, it’s been very stressful
with this dealership the entire process.
