2002 GMC Envoy service brakes, hydraulic problems

“SUBMISSION FROM CONSTITUENT RE GMC EXECUTIVE LETTER REPLY IN ENGINE STALLING/STOPPING WHILE BEING DRIVEN ON THE FREEWAY OF CALIFORNIA. *SMD THE CONSUMER STATED THE VEHICLE STALLED SEVERAL TIMES. ALSO, THE SERVICE ENGINE SOON LIGHT ILLUMINATED, DUE TO A FAULTY IGNITION COIL. THE DEALER ALSO REPLACED THE IGNITION SWITCH, AS THE POSSIBLE CAUSE OF THE ENGINE STALLING. THE CONSUMER CONTINUED TO EXPERIENCE STALLING ISSUES, AS THE DEALER WAS UNABLE TO DETERMINE THE CAUSE. WHEN THE VEHICLE STALLED, THE ABS AND BRAKE WARNING LIGHT ILLUMINATED. THE DEALER FOUND THE REAR SPEED SENSOR CONNECTOR BROKEN AND NOT SITTING PROPERLY IN THE SENSOR. THEY REPOSITIONED THE CONNECTOR AND SECURED IT TO THE SENSOR. THE CONSUMER DISCOVERED A RECALL, WHICH DESCRIBED THE SAME SYMPTOMS HE EXPERIENCED. RECALL # 04V289000. *JB”

“WHEN HAVING MY 02' ENVOY SERVICED AND STATE INSPECTION BY MY GMC DEALER THE SERVICE MANAGER CALLED AND TOLD ME, I WOULD NEED TO R/R MY FRONT ROTORS. THE PADS WERE HALF WORN BUT THE ROTORS SMOOTH SURFACE DID NOT EXIST. IT LOOKED LIKE THEY WERE NOT MACHINED THOROUGHLY. SER. MGR THOUGHT I LIVED NEAR THE SHORE, STATING SALT WATER WOULD USUALLY CAUSES THIS. I DO NOT LIVE NEAR THE SHORE AND DO NOT GO THE BEACH. I DRIVE THIS VEHICLE TO AND FROM WORK ALL HIGHWAY DRIVING. MY VEHICLE HAS 41225 MI AND HAS ALWAYS BEEN SERVICED BY GM. I HAVE OWNED GM VEHICLES FOR 38 YRS AND THE CARS WITH ROTORS NEVER LOOKED LIKE THIS. THIS LOOKS LIKE A MANUFACTURING IMPERFECTION. FROM REVIEWING THE ODI LIST FOR THIS VEHICLE, OTHERS HAVE ALSO DOCUMENTED SIMILAR COMPLAINTS. IF I DID NOT BRING THE VEHICLE IN FOR THE STATE INSPECTION I WOULD NEVER HAVE KNOW THIS DEFECT EXISTED. THIS GAVE ME NEITHER WARNING IN BRAKING, STABILITY NOR SQUEALING/TICKING FROM EARLY WARNING SYSTEM. I SHOULD HAD ASKED FOR OLD ROTORS OR TAKEN A PICTURE. FRONT ROTORS AND PADS REPLACED AT MY EXPENSE. *TR”

WHEN TURNING, THE STEERING WHEEL HESITATES AND CAUSES THE VEHICLE TO JERK UNCONTROLLABLY. WHEN THE WINDOWS ARE DOWN, THE INTERIOR LIGHTS DIM DUE TO AN ELECTRICAL SHORT. THE TIRES WERE CHANGED FOUR TIMES, BUT CONTINUED TO FAIL. THE CONTACT STATED THAT THE BRAKES HAVE BEEN REPLACED REPEATEDLY. THE DEALER STATED THAT THE DISCS WERE FAILING DUE TO ADVERSE WEATHER CONDITIONS. THE CURRENT MILEAGE IS 68,000 AND FAILURE MILEAGE WAS 38,000.
