The Brake Pedal May Become Soft and/or Low on Acura TSX

Problem Description and Possible Solution

Some vehicles may develop a soft, low brake pedal. Our technicians tell us this condition may be caused by a faulty vehicle stability assist (VSA) modular control unit. If this is the case replacement of the VSA modular control unit would be required.

Pedal goes all the way to the floor and is 'mush'...but I can 'pump it up'. No weird noises or cryptic messages on the leaky fluid. Fluid reservoir remains full, and I've got good discs...just not working as it should. Still looking for a solution.
Intermittent problem with soft brake pedal. Had brakes bled$. Had master cylinder replaced$$. Still have problem. Will replace vsa next. How aggravating.
This was already fixed on my 2007 tsx a few years ago and I am taking it in again this Thursday for the same problem! The odometer only just turned over 21,000!
After sudden jarring i.e. pothole or road hump transition, brake pedal becomes soft. This can last for several hours or all day. Usually returns within a day. Has happened after emergency maneuver like quick brake and turn.
My brake peddle goes all the way to the floor and barely stops me. Sometimes the anti lock brake kicks in but doesn't do anything except make the peddle jump. Also, when I'm stopped at a signal my car will start rolling. It isn't fixed yet I'm looking for a solution and will try the VSA. Bleeding the brakes did nothing.
