COMPLETE BRAKE FAILURE WHILE TRAVELING IN CAR OVER A BRIDGE IN NEW YORK CITY. I HAD BEEN ROUTINELY DRIVING THE CAR FOR ABOUT 15 MINUTES PRIOR TO THE INCIDENT. WHEN I WENT TO APPLY THE BRAKES IN TRAFFIC, MY FOOT DEPRESSED THE BRAKE PEDAL AND IT TRAVELED TO THE FLOOR. REPEATED ATTEMPTS TO BRAKE CAUSED THE SAME TO OCCUR. NEARLY MISSED A MAJOR REAR END COLLISION WITH THE CAR IN FRONT OF ME AND POSSIBLE INJURIES BY DROPPING THE TRANSMISSION INTO THE LOWEST GEAR AND SLAMMING ON THE PARKING BRAKE. DEALER SAYS MY ENTIRE BRAKE LINES ARE CORRODED AN…

"REDUCED ENGINE POWER/STALILITY CONTROL DISENGAGED" MESSAGE DISPLAYED, ENGINE WENT TO IDLE AND WOULD NOT EXCEED 5-10 MPH. TRAFFIC FROM BEHIND SERVED TO AVOID DECELERATING VEHICLE. I UNDERSTAND THIS IS SOMETHING THAT IS SOMEWHAT COMMON WITH THESE GM MODELS. THE POSSIBILITY OF REAR END COLLISIONS MAY BE EXPERIENCED DUE TO RAPID DECELERATION DUE TO LOSS OF POWER.

VEHICLE POWERS DOWN WITHOUT ANY PATTERN, RHYME OR REASON. IT WILL DO IT AT 5 MPH, AND AT 55 MPH, WHEN DRIVEN A LOT, AND WHEN NOT.

IT STRANDED ME IN THE CENTER OF A FREEWAY IN WINTER. WHEN IT SITS FOR A WHILE, IT RESETS, ONLY TO…

WHEN DRIVING AT LOW SPEEDS (LESS THAN 10 MILES PER HOUR) OR STARTING FROM A STOP, THE TRACTION CONTROL WILL AUTOMATICALLY ENGAGE WHEN THE GAS PEDAL IS APPLIED. WHEN THE TRACTION CONTROL ENGAGES, A TOTAL LOSS OF INPUT TO THE ENGINE RESULTS AND THE VEHICLE DOES NOT MOVE (IT ESSENTIALLY STALLS). I WAS ALMOST STRUCK IN AN INTERSECTION WHILE WAITING TO MAKE A LEFT TURN ON A GREEN LIGHT IN EARLY DECEMBER OF 2011. I WAS STOPPED IN THE MIDDLE OF THE INTERSECTION WAITING TO TURN LEFT.
