NHTSA complaint: 2002 CHEVROLET SUBURBAN — SERVICE BRAKES, HYDRAULIC
BEGAN EMERGENCY BREAKING AND EVASIVE MANEUVERS. SHORTLY AFTER BEGINNING TO TURN, THE ABS LIGHT CAME ON AND ALL 4 WHEELS LOCKED. THE RESULT WAS A 180 DEGREE SPIN ACROSS 5 LANES OF I30 JUST SOUTH OF DOWNTOWN DALLAS. WE ALMOST AVOIDED ANY COLLISION, BUT IT COULD HAVE BEEN HORRIBLE AS WE WERE CLOSE TO HITTING AT LEAST 7 TO 10 VEHICLES WITH SPEED DIFFERENTIALS OF ABOUT 50MPH WHILE OUT OF CONTROL. THE FAILURE CODE WAS THE EBCM RELAY, AND THE SYSTEM WORKS IF THE AMBIENT TEMPERATURE IS COLD ENOUGH, THOUGH IT FAILS ON BUMPS SOMETIME. TYPICAL BAD SOLDER JOINT BEHAVIOR. MANY PEOPLE ARE REPAIRING THESE MODULES BY RE-SOLDERING THE RELAY CONNECTIONS. *JS
