AIR BAGS
I RECEIVED AN AIRBAG RECALL ON MY GMC SIERRA SLT PICKUP TRUCK ON MAY 27,2016. I AM SITTING HERE FOUR YEARS LATER ON JUNE 15,2020 AND STILL NO REMEDY! I HAVE CONTACTED MY LOCAL DEALERS AND THEY TELL ME THAT THEY DON'T KNOW WHAT TO TELL ME. I HAVE BEEN CONTACTING THEM PERIODICALLY THE WHOLE 4 YEARS. I HAVE GRANDCHILDREN WHO RIDE ON OCCASION IN THIS VEHICLE AND I FEAR FOR THEIR SAFETY. WHEN ARE WE GOING TO GET A FIX??!! I OWN TWO OTHER VEHICLES NOT GM PRODUCTS. ONE WAS FIXED IN 2 WEEKS, THE OTHER IN ABOUT A MONTH. THIS IS PATHETIC! WHAT AN EMBARRASSMENT. EASY TO SEE WHY FORD F150 OUTSELLS GMC/CHEVY AND RAM AND TUNDRA ARE CLOSING THE GAP. I DO FEEL SORRY FOR THE SERVICE MANAGERS WHO KEEP HAVING TO MAKE EXCUSES FOR AN INEPT CORPORATION. NEEDLESS TO SAY YOU WILL NEVER SEE ME OR MY FAMILY IN ANOTHER GENERAL MOTORS SHOWROOM OR VEHICLE. *TR

POWER TRAIN, STEERING, SUSPENSION
AT SPEEDS HIGHWAY SPEEDS 50 AND ABOVE THE TRUCK CAN SHACK HORRIBLE CAUSING TO APPLY VEHICLES HAZARDS AND PULLING OFF THE ROAD FOR FEELING LIKE THE TRUCK IS COMING APART WITH THE FEAR OF LOOSING CONTROL OF THE VEHICLE. THE HORRIBLE SHACK CAUSE NAUSEA AND DIZZINESS. I HAVE REPLACED WHEELS AND TIRES, SHOCKS, RE ALIGNED AND BALANCED MULTIPLE TIMES NOTHING HAS FIXED THE ISSUE. WILL BE IN TOUCH WITH A GMC DEALER ABOUT THIS SITUATION . *TR

POWER TRAIN
WHEN TRUCK IS IN MOTION SHIFTING FROM REVERSE TO FIRST/SECOND GEAR IT JUMPS FORWARD INTO GEAR. THERE IS A HESITATION SHIFTING INTO GEAR. IT IS A VERY WELL KNOWN PROBLEM WITH THE 8 SPEED TRANSMISSION. I HAVE BEEN IN CONTACT WITH THE DEALER BUT 3 DIFFERENT TIMES. THE KNOW THE PROBLEM AS DOES GMC. THEY ACTUALLY CAN FIX THE PROBLEM. BUT WILL NOT DO ANYTHING UNTIL GMC SENDS OUT A TECHNICAL BULLETIN. THERE HAS BEEN AN UNBELIEVABLE AMOUNT OF COMPLAINTS. I UNDERSTAND GMC IS HESITANT BECAUSE THEY MAY HAVE TO REPLACE TRANSMISSION AND OR TORQUE CONVERTER WHICH WOULD NATURALLY COST A LOT OF MONEY. BUT ALSO I UNDERSTAND CHANGING TO A DIFFERENT TRANSMISSION FLUID WILL HELP. BUT DEALER WILL NOT DO IT. THIS HAS BEEN GOING ON SINCE THE DAY I BOUGHT IT BRAND NEW AND I ONLY HAVE 5700 MILES ON IT. I HAVE NOT HAD ACCIDENT BECAUSE OF THIS. BUT CONCERNS ME WITH THE HESITATION AND JUMPING IN TO GEAR. ALSO IT DOES NOT DO IT EVERY SINGLE TIME. DEPENDS ON YOUR TAKE OFF SPEED. *TR

EXTERIOR LIGHTING
WHILE THE HEAD LIGHTS AND FOG LIGHTS ARE ON, THE RIGHT HEAD AND FOG LIGHTS ARE DIM BUT THE LEFT HEAD AND FOG LIGHTS ARE BRIGHT. ALSO THE RIGHT TURN SIGNAL SHOWS ERROR MESSAGE ON THE CLUSTER THAT THE BULB NEEDS TO BE REPLACED AND YOU CAN HEAR IT BLINKING FAST, BUT WHEN I EXIT THE VEHICLE TO INSPECT THE SIGNAL I NOTICE THAT IT IS NOT BLOWN AND IT WORKS FINE BUT I STILL GET THE ERROR MESSAGE AND THE FAST BLINKING. BOTH STATED PROBLEMS OCCUR WHILE THE VEHICLE IS STATIONARY AND WHEN THE VEHICLE IS IN MOTION. *TR

SERVICE BRAKES
BRAKES FAILED "COMPLETELY", WITH NO WARNING. NO "WARNING LIGHT" ON THE INSTRUMENT PANEL WHILE DRIVING ON A PUBLIC ROAD IN THE COUNTY. ALL OF A SUDDEN ABSOLUTELY NO BRAKES. HAD RECENTLY HAULED A CAR ON A TRAILER FROM EMPORIA, KANSAS. WAS PREPARING TO HAUL CALVES TO THE SALE BARN. NOW THAT WOULD HAVE BEEN A TOTAL DISASTER. UPON INSPECTION, THE BRAKE LINES ARE SO RUSTED, THAT PINCHING OFF THE LINE RESULTED IN A RUPTURE IN ANOTHER LOCATION. I WAS TRYING TO GET SOME BRAKING ACTION, SO I COULD DRIVE IT TO A REPAIR SHOP. I'LL HAVE TO HAUL IT. *TR

ENGINE, POWER TRAIN
THE SAME ISSUE AS GM SERVICE BULLETIN PI1513F (RADIATOR LEAK) HAS HAPPENED ON MY 2017 GMC SIERRA. THIS SERVICE BULLETIN CURRENTLY COVERS 2014 - 2016 MODELS AND NEEDS TO BE EXTENDED TO COVER 2017 MODELS (AND POSSIBLY 2018). THIS ISSUE IS A RADIATOR THAT LEAKS ON THE PASSENGER OR DRIVERS SIDE ON THE WALL BETWEEN THE COOLING FINS AND THE END OF THE RADIATOR. *TR

AIR BAGS, UNKNOWN OR OTHER
DASHBOARD CRACKED AROUND THE AIRBAG OPENINGS. THIS SEEMS TO BE A COMMON PROBLEM AND MAY AFFECT PROPER AIRBAG DEPLOYMENT OR CAUSE THE DASH TO FRAGMENT AND HIT OCCUPANTS IN A COLLISION. THE PROBLEM WAS NOTICED JUST AFTER THE WARRANTY EXPIRED. THE DEALER WOULD NOT CORRECT, THE PROBLEM CONTINUES TO GET WORSE. THE VEHICLE IS NOT EXPOSED TO ANY EXTREME TEMPERATURE CHANGES OR PROLONGED SUN EXPOSURE AS IT RESIDE IN THE STATE OF MARYLAND WHICH EXPERIENCES 4 RATHER MILD SEASONS. THIS IS WELL DOCUMENTED BUT UNRESOLVED PROBLEM WITH THESE GM VEHICLES. *TR

ENGINE, POWER TRAIN, SUSPENSION
I'VE HAD SEVERAL PROBLEMS WITH THE TRUCK SINCE I BOUGHT IT 3 MONTHS AGO. I'VE FIXED ALMOST ALL OF THEM-ABS WAS ACTIVATING WHICH WAS PUSHING ME INTO TRAFFIC NEARLY CAUSING A WRECK SO I CHANGED THE ABS SPEED SENSOR AND HUB ASSEMBLY. FRONT SUSPENSION WAS GONE SO I REPLACED THAT; AS WELL AS STEERING PARTS, BRAKES, THE PARKING BRAKE DOESN'T WORK, FIXING IT NEXT. OIL SENDING UNIT, A/C BELT AND REFRIGERANT REPLACED. THE PROBLEMS LEFT ARE EVAP EMISSION VENT VALVE SOLENOID, THROTTLE PEDAL POSITION SENSOR, AND RANDOM/ MULTIPLE CYLINDER MISFIRE SOMETIMES AND CYLINDER 4 MISFIRE OTHER TIMES. IN 4X4 WHEN IT GETS UNDER A LOAD SOMETHING SOUNDS LIKE IT'S BINDING UP AND IT POPS BUT IT STILL WORKS. WHEN I SHIFT INTO DRIVE OR REVERSE OR ACCELERATE FROM A STOP IT HAS A SHIFT FEELING IN THE REAR WITH A THUMP SOUND. SOMETIMES I CAN PUSH THE GAS AND IT WON'T DOWNSHIFT TO SPEED UP WHEN I'M ON THE HWY BUT THAT'S PROBABLY THE TPPS. I JUST WANT MY 4X4 WORKING AND MY SHIFT THUMP FROM A STOP TO GO AWAY. HELP. IN 4X4 THE NOISE HAPPENS IN FWD REVERSE AND WHEN TURNING AND WORSE IN 4LO BUT HAPPENS IN 4HI AND AUTO BUT NOT IN 2HI. *TR
