SERVICE BRAKES
I WAS I 91 SOUTH HEADING IN TO HARTFORD CT, TRAFFIC WAS HEAVY AND AS A RESULT I WAS TRAVELING APPX 20 MPH AS I ENTERED THE RAMP EXIT LANE. I STEPPED ON BRAKE PEDAL AND THE PEDAL WENT TO THE FLOOR, FORTUNATELY I WAS ABLE TO VEER INTO THE BREAKDOWN LANE AND AVOID HITTING OTHER CARS. I SLOWLY MADE IT TO MY PLACE OF EMPLOYMENT AND LATER HAD THE TRUCK TOWED HOME. AS IT TURNS OUT I DISCOVERED THE ALL BRAKE LINES HAD CORRODED AND HAD TO BE REPLACED. I CONTACTED GM AS I THOUGHT IT VERY UNUSUAL FOR ALL BRAKES LINES TO BE SO SEVERELY CORRODED. THEY ATTRIBUTED THE SEVERE CORROSION TO THE FACT THAT THE TRUCK WAS 10 YEARS OLD AND REFUSED TO COVER THE EXPENSE AND CONSIDERED THE CASE CLOSED. BY DOING A SIMPLE INTERNET SEARCH I FOUND THAT THIS SAME PROBLEM IS QUITE COMMON AND MY MECHANIC ALSO INFORMED THAT GM ( POSSIBLY AS A RESULT OF THIS BEING A COMMON ISSUE) HAS MADE A AVAILABLE A BRAKE LINE REPLACEMENT KIT. *TR

BACKING OUT OF A PARKING SPACE I APPLIED THE BRAKES AND THE PEDAL WENT TO THE FLOOR. I HIT A STEEL POLE CAUSING DAMAGE TO MY REAR BUMPER. I WAS PRETTY SURE I KNEW WHAT WAS WRONG. I INSPECTED THE TRUCK AND FOUND BRAKE FLUID DRIPPING FROM UNDER THE VEHICLE IN THE AREA OF THE DRIVERS DOOR. FURTHER INSPECTION SHOWED THE BRAKE LINES WERE VERY RUSTED WHICH I ATTRIBUTE TO THE BRAKE LINE FAILURE. *TR

SEATS, ELECTRICAL SYSTEM
THE DRIVER SEAT HEATER RANDOMLY TURNS ON BY ITSELF. IT RANDOMLY SWITCHES FROM THE SEAT TO THE BACK OF THE SEAT TO BOTH AT THE SAME TIME, IN NO PARTICULAR ORDER. WHEN I TURN IT OFF IT JUST COMES RIGHT BACK ON AGAIN. I HAD THE MODULE IN THE DOOR REPLACED ONE TIME, BUT IT STILL DOES IT. I LIVE IN THE SOUTH, SO IT'S EXTREMELY UNBEARABLE DURING THE SUMMER MONTHS. I WILL GO FOR WEEKS AT A TIME WHEN IT DOESN'T DO IT, BUT THEN IT JUST SEEMS TO START AGAIN. THERE REALLY DOES NOT SEEM TO BE ANYTHING IN PARTICULAR THAT TRIGGERS IT. I THOUGHT MAYBE IT WAS GETTING WET WHEN IT RAINS, BUT SINCE I LIVE IN THE SOUTH WE HAVE HIGH HUMIDITY 95% OF THE TIME, SO WE HAVE MOISTURE PROBLEMS HERE ALL THE TIME. I CAN GO FOR WEEKS THAT IT DOESN'T HAPPEN, THEN IT JUST STARTS UP AGAIN. I HAVE SEARCHED THE PROBLEM ON GOOGLE AND FOUND THAT OTHER PEOPLE COMPLAIN ABOUT THE SAME PROBLEM WITH THIS PARTICULAR MODEL, BUT I CAN NOT FIND A SAFETY RECALL ISSUED BY GMC. *TR

SERVICE BRAKES
WHEN BRAKING AT SLOW SPEEDS THE ANTI LOCK BRAKES APPEAR TO ENGAGE CAUSING THE PULSATING BRAKE IN THE PEDAL. THE TRUCK STOPPING DISTANCE IS INCREASED AND THE BRAKES DO NOT FULLY ENGAGE CAUSING THE TRUCK TO BUMP THE CURB. THE PROBLEM ALSO MAY HAPPEN AT HIGHER SPEEDS SUCH AS 25 MPH AND CORRECTS WHEN THE PEDAL IS DEPRESSED FULLY TO THE FLOOR CAUSING THE BRAKES TO FULLY ENGAGE (LOCK UP). THE PROBLEM IS INTERMITTENT AND DOES NOT HAPPEN EVERY TIME. *TR

LATCHES/LOCKS/LINKAGES, ELECTRICAL SYSTEM
ERRATIC DOOR LOCK BEHAVIOR. PASSENGER AND REAR DRIVER SIDE DOOR WILL NOT LOCK OR UNLOCK CONSISTENTLY. THE PASSENGER SIDE LOCK NOT LOCKING RESULTED IN THE THEFT OF A HANDGUN FROM MY VEHICLE. THIS DEFICIENCY LEAVES THE VEHICLE SUSCEPTIBLE TO THEFT, CARJACKING, DOORS COMING OPEN ON IMPACT. PASSENGERS, ESPECIALLY CHILDREN ARE AT RISK OF OPENING THE VEHICLE DOOR WHILE IN MOTION. IN THE EVENT OF AN EMERGENCY THE DOORS EFFECTED CAN NOT BE UNLOCKED FROM OTHER THAN THE MANUAL LATCH BUTTON TO AID PASSENGERS. *TR
