NHTSA Complaint #10208878 — 2001 CHEVROLET BLAZER

IN THREE DIFFERENT OCCASIONS, 2 IN 06 AND 2 IN 07 THE BRAKES FAILED TO STOP IT'S AN INTERMITTENT INCIDENT. IN 06 AFTER INCIDENT, MASTER CYLINDER BRAKE WAS CHANGED (NOT KEEP OLD PART). AFTER THIRD INCIDENT, I TOOK IT TO DEALER. THEIR RESPONSE WAS NOTHING WRONG. BUT ON MY INTERVIEW WITH HEAD TECHNICIAN, MENTIONED THAT COULD BE THE ABS ACTIVATING, LIKE READING FALSE INSTRUCTIONS. WHAT COULD BE DONE, HE SAID TO CHANGE THE SENSORS BUT THERE WERE THREE ON THE CAR AND THOSE WERE EXPENSIVE AND THEN THERE ARE MORE OTHER COMPONENTS TO THE ABS THAT COULD ALSO BE THE CAUSE OF FAILURE. I STARTED TO INVESTIGATE ON THE INTERNET TO UNDERSTAND THE ABS AND THEN TO SEE IF I WAS THE ONLY ONE, AND THEN LOOKING FOR RECALLS. I CAME TO AN ARTICLE THAT DESCRIBED THE FAILURE EXACTLY AS IT HAS HAPPENED TO ME ALL THESE PAST EVENTS AND READS:...SIDEBAR: WHAT ARE THE MOST COMMON FAILURES WITH ABS THAT YOU HAVE DETECTED FROM YOUR VEHICLE INSPECTIONS? FOLCK: WELL, IN THE GENERAL MOTORS TRUCKS AND VANS, THE 4-WHEEL KELSEY-HAYES ANTILOCK BRAKE SYSTEM. THE BRAKE PEDAL IS SUPPOSED TO JUST PULSATE A LITTLE BIT AND STAY IN POSITION, BUT SOMETIMES IT GOES TO THE FLOOR. SIDEBAR: WHAT DOES THAT INDICATE WHEN IT GOES TO THE FLOOR? FOLCK: THAT THERE IS A FAILURE IN THE ABS. THEY HAVE A PROBLEM WITH THEIR ALGORITHM, AND IT WON?T SET A FAILURE CODE IN THE KELSEY-HAYES 4-WHEEL. IN LAYMEN?S TERMS, AN ALGORITHM IS A SEQUENCE OF FUNCTIONS THE COMPUTER IS SUPPOSED TO TAKE. THERE ARE GLITCHES IN THE ALGORITHM, AND GM HAS ACKNOWLEDGED THE ALGORITHM FAILURES. (EDS. NOTE: SEE THE ARTICLE IN THE MONEY SECTION OF USA TODAY, "GM: COMPUTER GLITCH COULD AFFECT BRAKES", 05/22/98.)" ... FIRST OF ALL, MY SAFETY IS FIRST AND THE MANUFACTURER HAS TO FIX THIS PROBLEM RIGHT AWAY. I AM NOT IN THE POSITION OF SELLING THE CAR SINCE I AM STILL PAYING DEARLY FOR IT AND SECOND, I WOULD NOT LIKE TO PASS THIS PROBLEM TO SOMEONE ELSE. *TR
