I picked up my vehicle on Thursday, and waited until today to see if any issues would return post-repair. The Chevrolet dealership replaced the Brake Pressure Modulator Valve. The Electronic Brake Control Module wasn't replaced due to the issue abating after the BPMV was replaced.
I've driven the vehicle approximated 50 miles since receiving the it back, and have had no further issues. One difference I have noticed is that while applying brake pressure at low speed, (i.e. backing out of a parking space and applying brakes before placing vehicle into Drive) I have noticed the brakes are less aggressive in it's grabbing power. The pedal feel hasn't changed, just the way the vehicle's brakes react when applying similar pressure at crawl speeds. But interestingly, I haven't noticed this during faster speeds.
On an even better note, my car is covered under the Certified Pre-owned GM program, good for bumper-to-bumper. So the repair was free of charge! All-in-all a good couple of days.
If I experience any further issues with the braking system, I'll be sure to update this thread. Thanks for reading...
