SERVICE BRAKES, HYDRAULIC
MY TRUCK WAS PARKED. I STARTED MY TRUCK. I APPLIED THE BRAKE TO PUT MY TRUCK IN GEAR. THE BRAKE PEDAL WENT COMPLETELY DOWN TO THE FLOOR. I INSPECTED UNDER MY TRUCK, AND THERE WAS A PUDDLE OF BRAKE FLUID UNDER THE DRIVER'S SIDE AREA ON THE CEMENT. I SAW THAT ALL THE BRAKE LINES CONNECTED TO THE ABS ELECTRO-HYDRAULIC CONTROL UNIT ARE SEVERELY RUSTED, AND ONE OF THEM WAS LEAKING SEVERELY. I HAD MY TRUCK TOWED HOME. THERE WAS NO WARNING LIGHT ON THE DASH THAT WAS BLINKING TO TELL ME I THAT I WAS HAVING A PROBLEM WITH MY BRAKES. THEY WERE WORKING FINE PRIOR TO THIS FAILURE. I WILL DOCUMENT THE CONDITION OF THE BRAKE LINES WITH A PICTURE AND BRAKE MECHANIC WITNESSES BEFORE ANY REPAIRS. I AM IN THE PROCESS OF LOCATING A BRAKE REPAIR BUSINESS. *TR

POWER TRAIN
STARTING AT <5K MILES THE VEHICLE POWER TRAIN CLUNKED WHEN SHIFTING FROM 2ND TO 3RD GEAR. NOW AT 70K MILES IT CLUNKS WHEN SHIFTING BETWEEN ALL GEARS EXCEPT FINAL DRIVE. THE DEALERSHIP REPLACED THE OUTPUT SHAFT ON THE TRANNY, THEN THE U-JOINTS, AND MODIFIED THE ELECTRICAL SHIFT PATERN. IT STILL CLUNKS. POWER STEERING INTERMITTENTLY LOCKS UP AT SLOW SPEED TURNS, ESPECIALLY WHEN BRAKING. LIGHT BULBS BURN OUT ALMOST EVERY THREE MONTHS. HAD TO PAY ($486.00) FOR REPLACING THE INTAKE MANIFOLD GASKET WHEN VEHICLE HAD LITTLE OVER 40K MILES. BRAKES FADE AND THE PEDAL ALMOST GOES TO THE FLOOR, AGAIN INTERMITTENT. I HAVE ALMOST CAUSED SEVERAL ACCIDENTS DUE TO THE STEERING AND BRAKE ISSUES. GMC ISSUED A LETTER STATING "THIS IS A NORMAL OCCURANCE AND WILL NOT CAUSE DAMAGE." WELL, IT'S GETTING WORSE IN SOUND AND CLUNKING HARDER DURING SHIFTING. *TR
