ELECTRICAL SYSTEM, ENGINE, STEERING
WHEN MAKING SLIGHT LEFT TURNS, THE TRUCK WOULD FLASH STABILITRAK ON THE DISPLAY AND THE STEERING WHEEL WOULD AUTOMATICALLY PULL OUT OF MY HANDS AND MAKE THE WHEELS STRAIGHTEN UP. THE RADIO WOULD THEN GO DEAD AND THEN 5 TO 10 SECONDS LATER THE ENTIRE TRUCK WOULD TURN OFF. THIS HAPPENED WHILE DRIVING DOWN THE ROAD. THIS HAPPENED ON 2 SEPARATE OCCASIONS WITH NO OTHER WARNINGS. I CONTACTED GMC AND THEY HAVE NOT GIVEN ME ANY TYPE OF ANSWER OR ASSISTANCE.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
ROOF ANTENNA LEAKING AFTER 2.5 YEARS THE ROOF MOUNT ANTENNA FOR XM RADIO STARTED LEAKING INTO HEADLINER CAUSES RADIO TO GET INTERMITTENT SIGNAL. LEAK TRAVELS DOWN DRIVER SIDE PILLAR INTO DASH BOARD WHICH WILL CAUSE ELECTRICAL SHORTING AND FAILURE. THIS PROBLEM IS DUE TO A FAULTY DESIGN OF THE ANTENNA. THERE ARE THOUSANDS OF COMPLAINTS ONLINE REGARDING THIS PROBLEM. DEALER REFUSED TO REPLACE AT THERE EXPENSE. CONTACTED GM WHO ALSO REFUSED TO REPLACE IT. THIS WAS A $60,000 TRUCK LESS THAN 3YRS OLD. IT GOT MY ATTENTION BECAUSE I USE XM RADIO AND LOST RECEPTION. THERE MUST BE MANY MORE WITH THIS PROBLEM WHO DON'T EVEN KNOW IT BECAUSE THEY DON'T USE XM RADIO. THIS IS A SERIOUS PROBLEM HAVING A LEAK TRAVELING DOWN INTO DASHBOARD WHAT ELSE IS AFFECTED AIR BAGS, LIGHTS, BRAKES ETC. THE DESIGN OF THIS IS AWFUL GMC IS EXTREMELY NEGLIGENT NOT RECALLING ON THIS PROBLEM

ELECTRONIC STABILITY CONTROL (ESC), ELECTRICAL SYSTEM, STEERING
TRUCK HAS 3 PROBLEMS THAT CAN PUT MY FAMILY'S LIFE IN DANGER. 1- SOMETIMES OUT OF NOWHERE AT LOW SPEEDS WHEN YOU TURN THE STEERING WHEEL TO MAKE A LEFT OR RIGHT TURN THE 'STABILITRAC' LIGHT FLASHES IN THE SCREEN AND LOCKS AND WON'T LET YOU TURN THE STEERING WHEEL.AT THIS POINT YOU HAVE NO CONTROL OF THE STEERING WHEEL, IT LOCKS AND BOUNCES BACK AT YOU AND IF YOU KEEP TRYING TO TURN IT, THE ENGINE CUTS OFF ALL POWER AND IT STALLS, JUST DIES. I ALMOST GOT READ ENDED A COUPLE OF TIMES ALREADY DUE TO THIS PROBLEM. JUST THIS MORNING I WAS MAKING A RIGHT ONTO A LOCAL MCDONALD'S AND THE STEERING WHEEL LOCKED AND THE ENGINE DIED ON ME. I HAD TO QUICKLY TURN IT ON AGAIN AND KEEP GOING.ANOTHER TIME IT HAPPEN AS I WAS MERGING INTO TRAFFIC. VERY SCARY! PROBLEM NUMBER TWO, I THINK ITS JUST A MATTER OF TIME BEFORE THE STEERING WHEEL LOCKS ON ME ON HIGH SPEEDS. SOMETIMES WHEN I'M ON THE FREEWAY, THE SAME CHIMES COME ON WHEN I STEP ON THE BRAKES, THE CENTER SCREENS GOES BLACK, AND THE SAME 'STABILITRAC' WARNING COMES ON THE SMALLER SCREEN BEHIND THE STEERING WHEEL. I'M AFRAID TO TAKE IT ON A WINDING ROAD FOR FEAR THAT THE STEERING WHEEL WILL LOCK ON ME CAUSE AN ACCIDENT. 3- SERVICE BRAKE CONTROLLER SIGN AND CHIMES COME ON ANT WON'T GO AWAY. IT JUS KEEPS ON POPPING ON AND ON AND ON AND THEY GO AWAY WHEN YOU TURN OFF THE TRUCK, AND COME ON AGAIN MONTHS OR WEEKS LATER. I DID HAVE IT CHECKED AT MY LOCAL DEALERSHIP.THEY TESTED IT, SOLD ME NEW GROUND AND HOT WIRES. IT WAS GOOD FOR ABOUT 4 WEEKS BEFORE THE SAME PROBLEMS CAME BACK AGAIN. I DID SOME RESEARCH ON SOME OF THE FORUMS AND YOU TUBE VIDEOS AND BY FAR I'M THE ONLY ONE WITH THE SAME PROBLEM. VERY AFRAID TO CAUSE AN ACCIDENT.

ELECTRICAL SYSTEM, SEATS
VEHICLE STARTED SHOWING "SERVICE LANE DEPARTURE SYSTEM, SERVICE PARK ASSIST, SERVICE TRAILER BRAKE SYSTEM" ALARMS WHILE DRIVING. UPON TAKING IT TO THE DEALER FOR SERVICE IT WAS FOUND TO HAVE BROKEN WIRING FOR HAPTIC MOTOR FOR DRIVERS SEAT. NOT ONLY DID THIS CAUSE A POSSIBLE SAFETY ISSUE WITH THE LANE DEPARTURE SYSTEM AND TRAILER BRAKE SYSTEM NOT WORKING CORRECTLY, BUT IT ALSO CAUSED A POSSIBLE FIRE CONCERN DUE TO BROKEN WIRING.

SERVICE BRAKES
HAVING ISSUES WITH HARD BRAKE PEDAL. IT HAPPENED A FEW TIME WHEN THE TRUCK WAS NEW BUT COULD NEVER DUPLICATE IT. TWICE IT ALMOST CAUSED AN ACCIDENT. I HAVE SINCE FOUND A WAY TO DUPLICATE IT. WHEN BACKING A BOAT TRAILER DOWN A RAMP EVERY TIME THEY BECOME HARD, I HAVE TO RIDE THE EMERGENCY BRAKE, BUT IT ONLY HAPPENS WHEN THE BOAT IS ON THE TRAILER. I HAVE RESEARCHED THIS OVER THE YEARS BUT NOT TILL RECENTLY HAVE I SEEN OTHER REPORTS OF TRUCK WITH THIS ISSUE. I HAVE NOT CONTACTED THE DEALER YET BUT WILL IN THE NEXT WEEK OR SO WHEN I CAN TAKE OFF TO GO. I DO NOT NOW DATE OF FIRST OCCURRENCE BUT I PUT A RANDOM DATE IN 2015.

SERVICE BRAKES
WHILE IN MOTION THE BRAKE PEDAL GOES HARD AND IS DIFFICULT TO STOP. I BELIEVE THIS IS THE CAUSE OF A LOW SPEED INCIDENT I HAD EARLIER THIS YEAR. THE ISSUE OCCURRES MOSTLY AT SLOW SPEEDS IN STOP AND GO TRAFFIC. IF FEELS LIKE THE BRAKE BOOSTER FAILS AND THE PEDAL IS BOTTOMED OUT. IT HAPPENS FREQUESNTLY WHILE HAULING A TRAILER IN REVERSE. VERY DANGEROUS SITUATION.

POWER TRAIN
STARTING THE VEHICLE I'M PUTTING THE TRUCK IN REVERSE, THE TRUCK LUNGES BACKWARDS. ALSO A VIOLENT JERK OF THE VEHICLE HAPPENS. THIS HAPPENS A MAJORITY OF THE TIME. PUTTING THE VEHICLE INTO GEAR TO DRIVE I HAVE A VIOLENT JERK AND A LOUD NOISE. THE TRUCK DOES NOT LUNGE FORWARD WHEN PLACING THE TRUCK INTO DRIVE. THIS HAPPENS A COUPLE OF TIMES A DAY. THIS IS NOT AN ISOLATED INCIDENT.
