It releases brakes and deactivates the BAS a second after I take my foot off the brake pedal. I have no BAS / EPS warning lights in the dash.

Obviously, this is dangerous and I have unplugged the BAS / EPS module. Any ideas where to start trouble shooting? I think these cars also have yaw and steering angle sensors that are inputs for the BAS / EPS?

Thanks in advance!
Did you scan for errors and what are the error codes?

Also did you recently changed your battery and forgot to reset the BAS.
