Brake Light On problems of the 2007 Nissan Pathfinder

I am writing to inform you of an intermittent brake failure/ un-commanded vehicle acceleration problem with the 2007 Nissan Pathfinder. On April 4, 2015 I brought my 2007 Nissan Pathfinder to the Nissan austin northtown dealership (austin, TX) for scheduled maintenance, which included servicing/replacement of my brakes, pads, and fluids. In the three weeks since this service was completed I have encountered several brake failures in which: (1) the brakes failed to hold pressure resulting in the vehicle accelerating forward from a stop several feet, (2) the vehicle accelerated when applying brake pressure when attempting to slow the vehicle to a stop, (3) the brakes failed to act upon attempting to stop the vehicle from moving forward. These events have been intermittent and have occurred on the following dates: 04 Apr 2015 SUV exhibited un-commanded acceleration while holding brake at stop light 05 Apr 2015 SUV exhibited un-commanded acceleration while holding brake at stop light 08 Apr 2015 SUV exhibited un-commanded acceleration while holding brake at stop light 12 Apr 2015 SUV exhibited un-commanded acceleration while braking to a stop 13 Apr 2015 SUV brought to north town Nissan, mechanics unable to replicate event while Nissan mechanics have assured me that the events were coincidental, upon further investigation, I have learned that a customer experienced a similar event February 7, 2009, and has since filed a complaint with the national highway transportation safety board. I would greatly appreciate if you could further investigate this matter and contact me at your earliest convenience. I have been fortunate to have avoided several close accidents during which case my family was on board the vehicle. Myself, my family, or countless other lives may not be as fortunate if this matter is not promptly researched and resolved.
