With reference to the P2A00 code, if the "air-fuel sensor " or
commonly called oxygen sensor(s) goes bad, then your 2007 is covered
under the emissions warranty. This should be fixed soon so you don't
risk damaging the catalytic converter. The conditions may be different
from that other owner, but if the OBD-II system tell you there is a
problem with the oxygen sensors, I'd pay attention.

There were earlier Accords with P0420 problems. Honda recommended
replacing the converter. I managed to help one owner fix it by
replacing the (IMO junk) Denso sensors with Bosch planar sensors. Good
thing I recommended that, otherwise that P0420 is going to come back.
But your sensors are probably different.

As far as rotor control goes, I'm really not familiar with this code.
But if you have traction or stability control, where the ECU actively
manages the brake force to the rotors then it too should be looked at.
If there is a fault here, again, it should be covered under warranty
repairs. And for safety reasons, I would pay attention to this too.
It's not like many OBD-II "gas cap loose" type of codes because the
pressure sensors were to sensitive.

I assume you'll have Honda look at the problems, right?
