SINCE PURCHASING SUV NEW, I HAVE HAD 3 FAILURES TO CRANK DUE TO A DESIGN DEFECT IN THE HOT LEAD CABLES THAT ATTACH TO THE BATTERY. THE LEAD WASHER USED BETWEEN THE TWO LEADS BECOMES MISSHAPED AND LOSES THE ABILITY TO CAUSE A CONNECTION. THE DANGER TO HUMAN LIFE IS DIRECTLY RELATED TO WHERE THE DRIVER HAPPENS TO BE WHEN THIS CONNECTION FAILS TO OCCUR. I HAVE BROKEN DOWN AT HOME (WHICH WAS SAFE) , 200 MILES FROM HOME AT A HOTEL (WHICH WAS NOT SAFE) AND IN THE SCHOOL PARKING LOT. THIS IS A COMMON PROBLEM AMONG THE MANY I KNOW THAT HAVE GMC SUV'S OR TRUCKS THAT USE THIS DUAL HOT LEAD SYSTEM. IT IS A DEFECT IN THE DESIGN BECAUSE THE LEAD WASHERS THEY USE BECOME MISSHAPED OVER TIME. AS YOU CAN SEE I HAVE LESS THAN 35,000 MILES ON THIS VEHICLE. A VEHICLE WITH THAT MILEAGE SHOULD BE MORE DEPENDABLE. GMC SHOULD FIX THE DEFECT OR EXTEND THE WARRANTY FOR THESE FAILURES.*AK

REPEATED EXCESSIVE WEAR ON FRONT BRAKE PADS AND NOW ON REAR BRAKE DRUMS. WE ARE VERY CONSERVATIVE DRIVERS AND TYPICALLY GET 80-100,000 MILES ON A SET OF BRAKES. THIS IS OUR SECOND SET OF FRONT PADS. WE DO TOW HEAVY LOADS. THE SUBURBAN IS EQUIPPED WITH A HEAVY DUTY TOWING PACKAGE . IT HAS ALREADY HAD THE STEERING GEAR BOX REPLACED BY THE DEALER. THE FRONT PADS HAVE BEEN REPLACED ONCE AND THE REAR BRAKES HAVE BEEN ADJUSTED, ALSO THE MASTER CYLINDER HAS BEEN REPLACED BY THE DEALER. THE BRAKES JUST DO NOT SEEM OF SUFFICIENT CAPACITY TO STOP A VEHICLE OF THIS MASS TOWING LOAD. WE'VE OWNED SUBURBAN'S SINCE 1973 SO WE DO FEEL WE HAVE A DEGREE OF EXPERIENCE IN THIS AREA. FINALLY WHEN THE VEHICLE IS DRIVEN AT HIGHWAY SPEEDS AND A BUMP IS HIT, THE ENTIRE ELECTRICAL SYSTEM SHORTS OUT FOR APPROXIMATELY 1/6-1/5 OF A SECOND CAUSING EVERYTHING TO GO DARK. I SUSPECT AN EXPOSURE IN A WIRING HARNESS. *JB *****DIMSII IVOQ ENTRY POSTED AFTER 12/12/02 CUT OVER TO ARTEMIS****763731
