FUEL SYSTEM, GASOLINE
BEGAN TO SMELL FAINT RAW GAS FUMES AROUND THE VEHICLE IN THE SUMMER. IN THE AUTUMN MONTHS THE RAW GAS ODOR SMELL INTENSIFIED AND WAS VERY STRONG WITH AN OVERCOMING PRESENCE IN THE CABIN WHILE DRIVING. I BROUGHT THE VEHICLE TO MY SHOP FOR DIAGNOSTIC. THE MECHANIC (NON GMC GARAGE) CALLED BACK SEVERAL HOURS LATER AND SAID I HAD BEEN DRIVING A POTENTIALLY DISASTER. HE ASKED ME TO SEE FOR MYSELF. I WAS ABLE TO VIEW THIS FIRST HAND AFTER HE HAD REMOVED THE FUEL TANK FROM THE VEHICLE. THE FUEL PUMP IS MOUNTED INTO A DEEP SUMP ON THE TOP OF THE GAS TANK. THE SUMP WELL IS RATHER DEEP AND COLLECTS MUD, SILT, DEBRIS AND WATER WHILE DRIVING AND THAT COLLECTS AND BUILD UP OVER TIME INTO THE SUMP AND THAT STAYS MOIST AT ALL TIMES. OVER THE COURSE OF 6 YEARS THE FUEL PUMP HOUSING AND MOUNT RING RUSTED, ROTTED OUT AND STARTED LEAKING RAW GAS THAT WAS SPILLING ONTO THE HOT EXHAUST PIPE ALONGSIDE THE FUEL TANK. I DO NOT GO OFF ROAD WITH THE VEHICLE NOR DO I PLOW SNOW WITH IT. THE VEHICLE IS USED PRINCIPALLY IN HIGHWAY DRIVING. A FEW WEEKS LATER I WAS TALKING TO A FRIEND WHO OWNS A 2010 GMC SUBURBAN AND HE HAD THE EXACT SAME PROBLEM. I SUBSEQUENTLY WENT ON LINE, SEARCHED ON GOOGLE, AND DISCOVERED A NUMBER OF OTHER OWNERS THAT HAD THE SAME PROBLEM WITH THEIR VEHICLES. THIS IS A DESIGN FLAW IN WHICH THE TANK IS DESIGNED WITH THE DEEP CIRCULAR DEPRESSION (A PERFECT SUMP CONDITION) FOR THE MOUNTING OF THE FUEL PUMP AND WITH NORMAL ROAD DRIVING (MOST NOTABLY IN THE NORTHEAST OR NORTHWEST WHERE RAIN AND SNOW IS PREVALENT) THE SUMP WILL STAY MOIST WITH MUD AND DEBRIS COLLECTING CAUSING RUST IN THE FUEL PUMP HOUSING/MOUNTING RING. *TR

ELECTRICAL SYSTEM
I WAS DRIVING ON THE HIGHWAY WHEN ALL THE LIGHTS ON THE INSTRUMENT CLUSTER CAME ON AND WENT CRAZY AND SO DID THE RADIO. THE TRUCKS BRAKES LOCKED UP AND CAME TO A COMPLETE STOP. THE TRUCK TURNED OFF AND WHEN I TRIED TO TURN IT BACK ON IT WAS DEAD. OPEN UP THE HOOD AND DISCONNECTED THE BATTERY AND RECONNECTED AND THE TRUCK TURNED ON THIS HAS NOT BEEN THE ONLY TIME IT HAS HAPPEN. *TR

ELECTRICAL SYSTEM
3 OF MY 4 DOOR LOCK ACTUATORS HAVE FAILED. BOTH REAR DOORS COULD NOT BE LOCKED OR UNLOCKED EXCEPT MANUALLY FROM WITHIN THE VEHICLE. REACHING OVER THE SEAT TO UNLOCK A CHILD'S DOOR IN AN EMERGENCY CONSTITUTES A SAFETY HAZARD. IN MY OPINION, GMC SHOULD STEP UP AN ACKNOWLEDGE AND ADDRESS THIS ISSUE. *TR

VEHICLE WAS IN (D) DRIVE AND I WAS ABLE TO TURN THE IGNITION OFF. IS THIS NORMAL? I CHECKED WITH MY GMC DEALER AND THEY SAID IT HAD TO BE PUT ON THE COMPUTER TO BE CHECKED, HOWEVER WAS NOT COVERED BY ANY POSTED RECALL. IS THIS RELATIVE TO THE IGNITION RECALL? THANK YOU *TR

ELECTRONIC STABILITY CONTROL (ESC), SERVICE BRAKES, ELECTRICAL SYSTEM
MY TRUCK STARTED TO ACTIVATE THE BRAKES IN THE MIDDLE OF THE 3 LANE 680 FREEWAY, DOORS STARTED TO LOCK AND UNLOCK, NAVIGATION WENT DARK, MULTIPLE DIFFERENT DISPLAYS ON DASHBOARD, NUMBER OF LIGHTS FROM THE AIR CONDITIONER UNIT, CAME ON. ACCELERATION OR BRAKES WOULD NOT RESPOND, WE WERE UNABLE TO DRIVE OFF THE FREEWAY. IT WAS A SCARY MOMENT, WE WERE LUCKY THAT NO BIG RIG WAS FOLLOWING US, OR IT WOULD HAD RUNS US OVER, AND PROBABLY KILLED US. *TR

STRUCTURE:BODY, LATCHES/LOCKS/LINKAGES
AT 35K THE DRIVERS SIDE FRONT DOOR ACTUATOR FAILED AND WAS REPLACED UNDER WARRANTY. AT 40K THE PASSENGER SIDE DOOR ACTUATOR FAILED. I WAS TOLD THIS IS A COMMON PROBLEM WITH THIS VEHICLE DUE TO DEFECTIVE PARTS USED BY GMC. WITH NO ABILITY TO OPEN OR CLOSE THE PASSENGER DOOR FROM THE DRIVERS CONTROL, A POTENTIAL SAFETY ISSUE EXISTS. E.G. UNABLE TO PREVENT AN INTRUDER FROM ENTERING THE CAR AT A STOP LIGHT, OR ALLOW A SCARED CHILD TO EXIT AFTER AN ACCIDENT. *TR

AIR BAGS
BOTH PART NUMBERS152974468 (FRONT FRAME MOUNTED CRASH SENSORS) FAILED WITHIN 2 WEEKS OF EACH OTHER ON MY 2008 GMC SIERRA PICKUP TRUCK. THEY ARE SUPPOSED TO BE HERMETICALLY SEALED UNITS BUT BOTH SHOW SIGNS OF WATER INTRUSION, CORROSION AND SWELLING. WHEN THESE FAIL THE SIR SYSTEM IS SHUT OFF. I HAVE PHOTOGRAPHS OF THE PARTS IF YOU WOULD WISH TO SEE THEM. UPDATED 5/8/2015 *JS

STEERING
THE LOWER STEERING SHAFT IS MAKING A NOISE. TOOK TO A REPAIR CENTER AND SHOW THE SHAFT NEEDS TO BE LUBED IT MAKES A CREAKING NOISE WHEN DRIVING OVER HUMPS AND ALSO THE SLIP YOKE IN THE REAR OF THE TRUCK WHEN COMING TO A STOPPED POSITION THE DRIVE SHAFT MOVES AND BACK AND IT FEELS AS IF YOU WAS BEING BUMPED FROM THE REAR OF THE VEHICLE. THE TWO ISSUES ARE FOUND ALL OVER THE WEB REPORTING THESE ISSUES AND GMC AS NOT IDENTIFIED OR RESOLVED THESE ISSUES ESPECIALLY ON THESE MODELS. *TR

ELECTRICAL SYSTEM, LATCHES/LOCKS/LINKAGES
ALL FOUR DOOR LOCKS WERE INTERMITTENTLY INOPERATIVE & ONLY ABLE TO FUNCTION MANUALLY FROM THE INSIDE. TAKEN TO DEALER AND DIAGNOSED AS INTERNAL FAILURE IN DOOR LOCK ASSEMBLIES/ACTUATORS. ALL FOUR DOOR LOCK ASSEMBLIES WERE REPLACED AT A CUSTOMER COST OF $900+. THIS IS MY SECOND GMC VEHICLE THAT HAS HAD THE SAME PROBLEM AND AFTER SEARCHING THE INTERNET THIS SEEMS TO BE A FAIRLY COMMON PROBLEM. EVEN THE DEALERSHIP MECHANIC MENTIONED SURPRISE THAT IT HAS NOT BEEN RECALLED OR GMC HAS NOT BEEN FORCED TO FIX THE PROBLEM CONSIDERING HOW OFTEN HE HAD PERSONALLY DIAGNOSED & FIXED THIS SAME PROBLEM. THIS IS DEFINITELY A SAFETY ISSUE AS THE CUSTOMER IS UNABLE TO RELY ON THE DOOR LOCK SYSTEM OR LOCK/UNLOCK THE DOORS AS USUAL. MULTIPLE TIMES, MY VEHICLE SAT AT THE AIRPORT FOR DAYS UNLOCKED BECAUSE OF THIS FAILURE. SIMILARLY, MY TODDLER-AGED CHILDREN WERE ABLE TO OPEN THE DOORS TO THE BACKSEAT WITH THE VEHICLE IN MOTION DUE TO THE FAILURE IN THE AUTOMATIC ASSEMBLY. *TR

ON OCTOBER 15, 2013, APPROX 7:45 AM, SINGLE OCCUPANT, WAS ENTERING THE EXIT RAMP FROM FREEWAY WHEN TRUCK CRASHED AND ROLLED TWICE. THE AIR BAGS DID NOT DEPLOY. TRUCK WAS COMPLETELY TOTALED. OCCUPANT REQUIRED MEDICAL TRANSPORT TO HOSPITAL AND WAS KEPT FOR A WEEK FOR TESTING AND TREATMENT FOR INJURIES. COUNTY SHERIFF ATTENDED TO CRASH SITE AND SUBMITTED TRAFFIC REPORT. WITH ALL THE RECENT RECALLS OF GM PRODUCTS - LIKE IN OTHER CRASHES, THE AIR BAGS DID NOT DEPLOY. IGNITION. *TR

AIR BAGS
WARNING LIGHT CAME ON ABOUT AIR BAG, TOOK TO GMC DEALER AS GMC HAD NO RECALL ON THIS WARNING GMC DEALER RAN TEST DETERMINED THE PASSENGER AIR BAG SENSOR HAD CORRODED AND I HAD TO REPLACE IT AND IT WAS NOT COV BY WARRANTY, SO PD 317.00 TO HAVE REPLACED. SOMETHING THIS IMPORTANT IN THE VEHICLE SHOULD HAVE BEEN RECALLED AND SENSOR MOVED TO OTHER LOCATION AS IT WAS CORRODED FROM WEATHER? GMC DEALER TOLD ME 2 THINGS COULD HAPPEN IF I DIDN'T GET IT FIXED, COULD GO OFF RANDOMLY OR WOULD NOT DEPLOY IF IN ACCIDENT THEREFORE BOTH OF WHICH COULD HAVE CAUSED FATALITY IF HAPPENED IN OPERATION. WOULD LIKE COMPLAINT FILED AS I WILL NOT GET MY MONEY BACK, BUT GMC NEEDS TO BE AWARE OF THIS IN THIS YEAR TRUCK. MAYBE SAVE SOME LIVES IF IT IS RECALLED AND MOVED TO WHERE WEATHER CANT GET TO IT. GMC CUSTOMER SERVICE WAS OF NO HELP IN GETTING THIS REPLACED OR EVEN A REPORT MADE OF THIS INCIDENT, I HAD THIS REPLACED IN OCT. 2013 AND WAS TERRIFIED EVERYDAY DRIVING IT THAT IT WOULD GO OFF, AND CAUSE ME AN ACCIDENT, AND DEALER ADVISED ME THAT I HAD 2 OF THESE BAGS, SO AT LEAST THEY (SENSOR) DID NOT GO BAD AT THE SAME TIME...THIS WAS A LOT OF MONEY TO ME TO HAVE THIS FIXED PLUS THE 39.00 TO HAVE THEM RUN COMPUTER TEST ON IT. NEEDS TO PROB BE A RECALL ON THIS PART, AND RELOCATION OF WHERE THE SENSORS ARE. THANKS *TR

LATCHES/LOCKS/LINKAGES
I HAVE TO LOCK AND UNLOCK BOTH OF MY PASSENGER SIDE DOORS MANUALLY, BECAUSE THE LOCKS DOESN'T WORK WITH THE KEY FOB NOR INSIDE THE VEHICLE. I FEEL LIKE THIS IS A SAFETY ISSUE THAT GM SHOULD RECOGNIZE BECAUSE SOMEONE COULD HAVE VALUES STOLEN OUT OF THEIR VEHICLES IF NOT HAVE THE VEHICLE STOLEN IF THEY FORGET TO MANUALLY LOCK DOORS WHEN THERE IS A PASSENGER IN THE VEHICLE. *TR
