Default Lost almost ALL brakes (stopping)

If you read my previous thread on my noise I think this may be related in a way but anyway------

I Figured I start new thread cause this is a little different now. Was going down the road turned a corner and there goes the BUZZER and-- BRAKE/ABS/VSC TRAC/VSC OFF/ AND THE ANTI SKID SYMBOL! BUT i have ZERO brakes, I mean good thing i wasn't going fast or needed to stop in a hurry I would have been Screwed cause it took all I could to press on pedal to get it to stop from a slow speed. Cut off and restarted car several times but same thing so guess it gets towed to dealership in the morning------Wow Alternator / battery and now this al within 2 weeks

Booyah, first you are safe, that a good news.

I am really surprised when you told all brakes failed. The GX has a fail safe method when such things happen, it goes into limp mode wherein the accelerator opening angle is to the minimal and gets to idling state. And if the ECM regards total failure of the Brake system, the GX ignition is Auto off and making the throttle control valve deactive.
So what I see is you are in the first state of limp mode.
