REAR WINDOW HINGE BROKE OFF FROM WINDOW FRAME ON 2003 SUBURBAN. VERY RARELY OPENED WINDOW BY ITSELF ALWAYS OPENED ENTIRE HATCH. CAN NOT FIND ANY RECALLS OR COMPLAINTS BY GM BUT YET CAN FIND SEVERAL 100 COMPLAINTS BY INDIVIDUALS. GM WANTS 1,000 TO FIX. IT IS OBVIOUSLY A DESIGN FLAW AFTER PAYING $43,000 FOR IT GM SHOULD STEP UP. THEY WILL CHECK THE WELDS ON REAR WINDOW FOR A FLAW BUT NOT THE HATCH PART WHICH IS WHAT BREAKS. HAVE ALWAYS BOUGHT CHEVROLET AND THIS IS THE LONGEST ONE I HAVE OWNED BUT I WILL BE HEADING TO A DIFFERENT REAL SOON. READ ABOUT THE WINDOW BLOWING OUT AT HIGHWAY SPEEDS--GUESS WE SHOULDN'T CARE IF IT IS BLOWING AWAY FROM US--RIGHT. *TR

1) SUDDEN LOSS OF BRAKING POWER DURING STOP WITH NO WARNING. 2) PEDAL TRAVELS ALMOST COMPLETELY TO THE FLOOR. BRAKING FORCE IS MUCH LESS THAN NORMAL. THIS IS NOT AN INTERMITTENT CONDITION. 3) EXAMINATION SHOWS THAT A HARD (STEEL?) HYDRAULIC BRAKE LINE HAS CORRODED AND RUPTURED. *TR

AFTER AN INITIAL FAILURE OF THE HYDRAULIC BRAKE (LINE RUPTURED ABOUT TWO FEET BEHIND THE ABS VALVE) WHILE THE CAR WAS MOVING, AND AFTER THIS LINE WAS REPLACED, I INSPECTED THE REAR WHEEL BRAKE LINES AND NOTICED EXTREME CORROSION ON BOTH LINES THAT RUN FROM A JUNCTION CONNECTION ABOVE THE DIFFERENTIAL TO THE HOSES ON EACH CALIPER. WHILE CHECKING THE FITTINGS AND INSPECTING THE LEFT LINE IT LITERALLY CRUMBLED, BROKE AND STARTED LEAKING. I REPLACED BOTH LINES AND BLEED THE SYSTEM. THE CAR HAD BEEN INTO THE DEALER WITHIN LAST YEAR (APPROX.) FOR BRAKE LINE INSPECTION AFTER OBSERVING A LOT OF RUST. THE DEALER CLAIMED THAT LINES WERE OK AND THAT A LOT OF RUST WAS NORMAL AND OK. I HAD TO PAY FOR THIS INSPECTION. *TR
