Air bags did not deploy when another vehicle hit truck on front passenger side at 35-40 mph
May 31, 2025
The contact owns a 2008 GMC Sierra 1500. The contact stated that while the vehicle was parked and turned off at the residence, the front windshield cracked. Upon inspection, the contact noticed that the front driver's and passenger's side air bags had deployed without impact. The vehicle was towed to the dealer, where it was diagnosed, and it was determined that a short circuit was caused by water damage in the air bag modules underneath the front driver's and passenger's side seats. The vehicle was then towed to a body shop for the air bags to be replaced; however, the replacement parts were on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 38,000.

ALL FOUR POWER DOOR LOCK ACTUATORS HAVE FAILED. FIRST THREE FAILED BEFORE REACHING 30000 MILES. DEALER ADVISED THEY WERE NOT COVERED UNDER WARRANTY. I ARGUED WITH THEM, BY THE TIME MY TRUCK HAD 50000 MILES ALL FOUR HAD FAILED AND WAS TOLD THAT THE WARRANTY EXPIRED AT 36000 MILES. THIS IS A SAFETY HAZARD AND GM REFUSES TO ACKNOWLEDGE THE MILLIONS OF VEHICLES AFFECTED BY THIS ISSUE. GM WANTS $300 PER DOOR TO REPAIR. I SHOULDN'T HAVE TO PAY THEM $1200 FOR SOMETHING I PAID FOR WITH THE PRICE OF THE TRUCK.

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

THE VEHICLE IS A 2008 GMC SIERRA 1500. THE DRIVERS SIDE DOOR LOCKED AUTOMATICALLY WHEN THE VEHICLE WAS PUT INTO DRIVE. ONCE I HAD ARRIVED AT THE DESTINATION THE DRIVERS SIDE DOOR WOULD NOT OPEN AND I WAS NOT ABLE TO EXIT THE VEHICLE AS A RESULT. I ATTEMPTED TO USE THE ELECTRONIC LOCK TO RE-LOCK AND UNLOCK THE DOOR AND THIS HAD NO SUCCESS. ATTEMPTED ROLLING DOWN THE WINDOW AND OPENING THE DOOR WITH THE OUTSIDE LATCH WHICH ALSO HAD NO SUCCESS. TRIED MANUALLY LOCKING AND UNLOCKING THE DOOR AND NOTHING APPEARS TO ALLOW THIS DOOR TO BE OPENED USING THE INSIDE OR OUTSIDE DOOR LATCHES. I HAD TO EXIT THE VEHICLE USING THE PASSENGER SIDE DOOR WHICH OPENED AS IT SHOULD. NEITHER INSIDE OR OUTSIDE DOOR LATCHES FUNCTIONED. I BELIEVE THIS TO BE A MANUFACTURERS DEFECT AND THIS SHOULD BE PUT ON A RECALL LIST AND THE RESOLUTION SHOULD BE PROVIDED AT NO COST TO THE OWNERS OF THIS VEHICLE. *TR

MY CONCERN IS THREE DOOR POWER LOCKS HAVE GONE BAD AND REPLACED TWO SO FAR. MY CONCERN IS THE REAR DOORS ARE KEYLESS AND YOU CANT UNLOCK THEM FROM FRONT. I SPOKE TO GM AND THEY DON'T SEE A NEED TO RECALL TRUCK. I TALKED TO MY LOCAL MECHANIC AND GM DEALERSHIP AND THEY ARE SEEING A LOT OF FAILED POWER LOCKS ON THIS MODEL TRUCK. CAN I GIVE YOU A WHAT IF SCENARIO SAY THEIRS A FIRE IN FRONT AND I CANT UNLOCK REAR DOORS TO GET MY CHILDREN OUT WOULDN'T THAT BE A LIABILITY ISSUE IF I COULDN'T GET THEM OUT TO SAVE THEIR LIVES. *TR

MY SIERRA DEVELOPED A NOISE ON DECELERATION. TOOK IT TO THE GMC DEALER AND WAS TOLD IT HAD A WORN CAM. $5500 TO REPAIR, $7750 TO REPLACE ENGINE. I KNEW THAT A WORN CAM WOULD CAUSE LIFTER NOISE ALL THE TIME SO THAT WAS WRONG INFO. UPON FURTHER INVESTIGATION I FOUND OUT THIS TRUCK HAS ACTIVE FUEL MANAGEMENT. WHAT HAPPENED WAS A FAILURE OF THE SYSTEM. IT SHOULD BE NOTED THAT THIS TRUCK ALWAYS HAD HIGH OIL CONSUMPTION. I DEACTIVATED THE ACTIVE FUEL MANAGEMENT SYSTEM. THE TRUCK RUNS ON ALL 8 CYLINDERS, IS COMPLETELY QUIET AND NO LONGER USES OIL. IT IS BETTER THAN NEW. I ALSO FOUND HUNDREDS OF COMPLAINTS SIMILAR TO MY AND PAID FOR EXPENSIVE REPAIRS. THIS ACTIVE FUEL MANAGEMENT IS NOTHING MORE THAN A SCAM TO FALSELY INCREASE FUEL MILEAGE AND TO RIP OFF CUSTOMERS WHEN IT GOES BAD. IT CAN BE DEACTIVATED WITH A $175 CHIP.

LOOKED ON LINE MANY PEOPLE HAVE HAD THIS HAPPEN, A MECHANIC AT A CHEVROLET GARAGE TOLD ME IT IS PROBABLY IN THE CLUSTER PANEL/ COMPUTER?? BIG MONEY.

VEHICLE'S AIRBAGS DID NOT DEPLOY UPON COLLISION WITH TWO CONCRETE WALLS, CAUSING A LIFE THREATENING TBI AND ALSO SEVERE DAMAGE TO THE LEFT ARM WHICH RESULTED IN IT'S INABILITY TO CONTROL/USE BELOW THE ELBOW, AND ESPECIALLY THE HAND. THIS WAS DUE TO THE BRACHIAL PLEXUS INJURY THAT WAS CAUSED WHEN THE AIRBAGS DID NOT DEPLOY AS THEY WERE SUPPOSED TO. I HAVE ATTACHED THE REPORT FROM POLICE AND INSURANCE COMPANY (WITH PHOTOS).

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

REAR PASSENGER DOOR WILL ONLY LOCK/UNLOCK MANUALLY FROM THE INSIDE. I HAVE BEEN TOLD THE PROBLEM IS A FAILED DOOR LOCK ACTUATOR. IT WILL NOT LOCK/UNLOCK WITH POWER LOCK BUTTON OR KEY FOB AND THERE IS NO KEYHOLE EXCEPT ON DRIVERS DOOR. 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 AND I AM TRYING TO FIGURE OUT WHY IT HAS NOT BEEN RECALLED OR GMC HAS NOT BEEN FORCED TO FIX THE PROBLEM. WOULDN'T YOU CONSIDER A DOOR THAT DOES NOT LOCK/UNLOCK THE INTENDED WAY A SAFETY ISSUE? *TR
May 08, 2014
WE HAVE HAD THREE OF THE POWER LOCKS GO OUT - FIRST WAS FRONT PASSENGER, WHICH WAS UNDER WARRANTY AND COVERED FREE OF CHARGE, SO WAS THE SECOND - THE FRONT DRIVERS SIDE. BUT, THE REAR PASSENGER SIDE WENT OUT A YEAR LATER AND NOW THEY WILL NOT COVER IT UNDER WARRANTY. MY CONCERN IS THAT, HAVING SMALL CHILDREN, I HAVE HAD THEM LOCKED INSIDE THE VEHICLE AND THE UNLOCK DOESN'T WORK, SO I HAVE TO CLIMB THROUGH TO ACCESS THE DOOR LOCK. IN AN EVENT OF AN EMERGENCY, WHERE TIME IS OF ESSENCE - THIS IS A SEVERE ISSUE. *TR

DASHBOARD HAS CRACKED ABOVE THE DRIVERS INSTRUMENT DISPLAY, AROUND SPEAKER AND NOW HAS CRACKED AROUND THE PASSENGER SIDE AIR BAG WITH THE DASHBOARD BEING LOOSE. IF THE AIR BAG IS EVER TO DEPLOY IT WILL MORE THAN LIKELY HURT MY PASSENGER WHICH COULD BE MY WIFE, MY CHILDREN OR GRANDCHILDREN. THIS IS RIDICULOUS, THOUSANDS UPON THOUSANDS OF GMC VEHICLES HAS THIS SAME ISSUE !!!!!

TAKATA RECALL: GMC HAS KNOWN ABOUT THIS ISSUE WAY TO LONG AND STILL TO THIS DATE CANNOT GIVE ME A DATE OR TIME FRAME WHEN THEY CAN FIX MY ISSUE. THIS SHOULD HAVE ALREADY BEEN CORRECTED. THE SECOND ISSUE IS THE EPIDEMIC DASH CRACKING THAT IS OBVIOUSLY AN ENGINEERING ISSUE AND GMC SHOULD BE HELD ACCOUNTABLE TO CORRECT THIS DEFECT IN THEIR DASHES. MY DASH CRACKS ARE ALMOST IDENTICAL TO THOUSANDS OF OTHER GMC OWNERS AND WHEN THERE IS AN OBVIOUS FLAW, THEY SHOULD CORRECT IT. DOWN AT THE BOTTOM WHERE IS SAY WHEN DID THIS HAPPEN? I KNOW IF HAPPENED IT 2010, BUT NOT A SPECIFIC DAY OR MONTH.

"GMC DASH RECALL" MY 2008 GMC SIERRA DASH IS CRACKING AND I LOOKED UP THE PROBLEM ON GOOGLE AND IT LOOKS LIKE THOUSANDS OF OTHERS HAVE THE SAME PROBLEM AS ME. THE DASH IS CRACKED IN SUCH A WAY THAT AT A CERTAIN ANGLE I CAN SEE WIRES EXPOSED FROM THE AIRBAG COVER. I WOULD LIKE TO SEE A RECALL TO FIX THE CRACKED DASH.

SEAT BELTS
8 complaints
I was driving in a parking structure at low speed when a loud bang went off inside the cab. The hazard lights went off, there was an acrid electrical smell, and fine dust was coming from the steering wheel area. I stopped the truck and got out to look for a collision, but there was none. When I restarted the truck, the air bag light came on and I noticed that the seatbelts were retracted and no longer functional. I was not injured, but I believe that if this had happened in traffic or on the highway, I and my passenger could have been seriously hurt. The vehicle was towed to the GMC dealership, where they identified an error with the module that sends a signal to the airbags and seatbelts to deploy. Prior to this occurrence, I had no indication that the airbag/seatbelt system was faulty or in need of service.
Jan 02, 2025
Cranked my truck yesterday and put it in drive. Slowly drove about 300 feet and the pretensioner’s discharged in my seatbelts. I fortunately did not have it on yet, but the seatbelts are now unusable.

UNKNOWN. Front side passenger safety belt won't buckle, the latch appears to be blocking the buckle when in the open, unlatched position.
Dec 20, 2022
I started my 2008 GMC Sierra, crew cab and began to pull my drivers side seat belt across my body to latch it. I was about 1/2 way when I heard a loud bang that sounded like a gun going off to my right, the seat belt that I had in my hand pulled back tight pulling my hand with it. There was smoke and the smell of gun powder coming from the bottom of the passenger seat by the seat belt. With my heart pounding in my chest I got out of my truck as quickly as I could (my driver's side door was still open). Both the driver's side and passenger side seat belts were pulled tight and I was unable to get either to release. The truck is now sitting, unable to be driven safely with the seat belt on. The dealership said it would be just under $1,000 to fix plus towing and has no idea how or why it happened. This truck has never been in an accident and currently has about 140,000 mostly highway miles on it and I am the original owner. Searching online I found that there are other people on blogs who have had similar problems with exploding seat belt modules with a range of 40,000 miles to over 150,000 miles.
Jan 27, 2022
I WAS SLOWLY GOING ACROSS A PARKING LOT WHEN A LOUD BANG LIKE A GUN SHOT HAPPENED AND THE DRIVER SIDE SEAT BELT PULLED ME TIGHT AGAINST THE SEAT. THERE WAS A SMELL OF A CHEMICAL GAS IN THE CAB AND THE EMERGENCY FLASHERS CAME ON. I AM SURELY GLAD I WAS ONLY GOING A FEW MILES AN HOUR. NOW THE SEAT BELTS (BOTH SIDES) ARE LOCKED TIGHT. I UNDERSTAND THIS MIGHT NOT BE THAT RARE OF A PROBLEM BUT IT'S THE FIRST I'VE EVER HEARD OF IT.

SERVICE BRAKES, HYDRAULIC

BRAKE ROTORS WARPED AT 15K MILES, HAD THEM TURNED UNDER WARRANTY AT DEALER VEHICLE WAS PURCHASED FROM. AT 30K MILES ROTORS WARPED AGAIN, THIS TIME 1 BRAKE PAD WAS WORN DOWN TO 2MM THICK, THE REST APPEAR ALMOST NEW IN THICKNESS. DEALER TURNED ROTORS AGAIN AND REPLACED PADS FOR $200. REQUESTED AND WAS DENIED THAT THE BRAKE WORK BE COVERED UNDER WARRANTY BY DEALER AND GM CS. I TOOK OLD BRAKE HARDWARE HOME WITH ME AND STILL HAVE IT. I CONTEND THERE IS SOMETHING WRONG WITH THE DESIGN OR MATERIALS IN THE BRAKE SYSTEM OF THIS TRUCK CAUSING PREMATURE WEAR AND FAILURE OF "NON WARRANTY" BRAKE ITEMS SUCH AS THE PADS AND ROTORS. I CONTEND THAT THERE HAS BEEN A HANGING BRAKE PAD CAUSING THE ROTORS TO OVERHEAT AND WARP SINCE THE VEHICLE WAS NEW AND ANY WORK PERFORMED AT THE TIME OF THE 15K MILE ROTOR TURNING DID NOT CORRECT THE PROBLEM. IF BRAKE WORK NEEDS TO BE PERFORMED ON THIS TRUCK EVERY 15K MILES THERE IS A REASON THAT SHOULD BE COVERED UNDER WARRANTY. ONE TIME FREAK FAILURE I CAN SEE, TWO TIMES EVENLY SPACED AT 15K MILE INTERVALS AND I THINK SOMETHING IS WRONG WITH THE VEHICLES BRAKES DESIGN AND/OR MATERIALS. VEHICLE IS DAILY DRIVER, 15 MILES A DAY TO AND FROM WORK. GARAGED DURING THE WINTER, TAKEN OFF ROAD (FROZEN CORNFIELDS, DIRT FIELD ROADS) FOR A WEEK IN LATE FALL. USED TO TOW A FISHING BOAT A FEW TIMES A YEAR. OWNER IS A FORMER ASE CERTIFIED MECHANIC AND IS NOT AN AGGRESSIVE USER OF THE BRAKES.

TIRES
6 complaints
Tire sizes: 245/70r17. Three tires went bad between November 2022 and March 9th 2023. First tire, the front right, replaced because its outside tread was going bad really quickly. I could see the metal sticking out of it. Two tires need replacing because they are bulging. The back left tire bulged so bad my car was shaking up and down until I took it off. Thought everything was fine but the back right began to shake the car two days later.
Mar 09, 2023
Tire size: 265 75 R16. All four tires inside wall has failed about two inches all the way around the rim. The tires were purchased sometime in 2018 and are a little above the 50.000 mile warranty. They were inspected by NTB technicians in Lancaster and also in Canal Winchester Ohio. They will only replace one tire for free but l think and believe l can’t be the only one with 4 of these tires failing in the same vehicle. All four tires have failed. No inspection by police or insurance has been performed. No warning signs at all other l got under the vehicle to inspect a small oil leak and that is when l saw the problem.

IN COLD WEATHER, THE BRAKES MAY STAY ENGAGED, EVEN UPON RELEASING THE BRAKE PEDAL. THIS WILL HAPPEN SPORADICALLY, AND USUALLY UPON STARTING FOR THE FIRST TIME AT A GIVEN DAY. I WILL START DRIVING, THEN BRAKE WHEN REQUIRED, RELEASE THE BRAKE WHEN I WANT TO RESUME DRIVING, BUT THE BRAKES MAY REMAIN ENGAGED.

WHILE DRIVING A BRAND NEW 2008 GMC SIERRA, 4 DOOR, 4 WHEEL DRIVE WITH ONLY 872 MILES ON THE ODOMETER, GOING APPROXIMATELY 30 TO 40 MPH, THE STEERING KNUCKLE HOLDING THE TIE ROD BROKE ON DRIVERS FRONT SIDE. THE DRIVER IMPACTED A PULL CAMPER TRAILER EXPLODING THE TIRE UPON IMPACT WITH THE CAMPER. THE WHEEL RIM WAS TURNED SIDE WAYS AS IT IMPACTED THE TIRES OF THE CAMPER FLATTENING 2 TIRES CURLING THE CAMPER WHEEL RIMS AND CAUSING DAMAGE ALONG THE SIDE OF THE CAMPER. THEN IMPACTED A FORD CAR DOWN THE DRIVERS SIDE THAT WAS FOLLOWING THE CAMPER. THE IMPACT CAUSED THE AIRBAG TO DEPLOY IN THE TRUCK. THE TIRE ON THE TRUCK WAS FOUND OVER 200 FEET FROM THE IMPACT. THE MARKINGS ON THE TIRE WERE CONSISTENT WITH THE STEERING KNUCKLE BREAKAGE. INSPECTION BY BOTH THE TOW TRUCK OWNER AND THE COLLISION REPAIR SHOP NOTICED THAT THE PART LOOKED DEFECTIVE AND POINTED IT OUT TO THE OWNER OF THE TRUCK. THE TOW TRUCK OPERATOR OWNS AN IDENTICAL TRUCK AND WAS VERY CONCERNED ABOUT THE SAFETY OF HIS OWN VEHICLE. THIS VEHICLE HAS NOT BEEN REPAIRED AND IS AVAILABLE FOR INSPECTION. IF FAILURE WOULD HAVE OCCURRED A FEW HOURS LATER ON INTERSTATE 95 AT 70 MPH (A PLANNED TRIP) THE OUTCOME COULD HAVE BEEN MUCH DIFFERENT. *TR

WHILE SLOWLY BACKING MY 2008 GMC SIERRA PICK-UP TRUCK INTO THE GARAGE, THE MIRROR SURFACE CONTACTED THE SIDE OF THE GARAGE, CRACKING THE MIRROR. INSURANCE COMPANY RECOMMENDED HAVING AN AUTO GLASS SHOP REPLACE THE MIRROR, BUT A SMALL, FLIMSY PLASTIC CLIP THAT HAD BROKEN ON THE BACK OF THE MIRROR PREVENTED THEM FROM DOING SO. CUT HAND ON BROKEN MIRROR SURFACE AFTER REMOVED BY GLASS SHOP. DEALER ESTIMATED REPAIR AT $213.02. GM CORPORATE REFUSED TO ACKNOWLEDGE DEFECT IN MIRROR BACKING CLIP AND REFUSED ANY ASSISTANCE WHATSOEVER (DISTRICT SPECIALIST LEVEL REFERRAL FROM OWNER RELATIONS CENTER. I THOUGHT THAT FLEXIBLE MIRROR ASSEMBLIES WERE SUPPOSED TO SURVIVE MINOR COLLISIONS - A PREVIOUS GM VEHICLE (BLAZER) PERFORMED ADMIRABLY IN A 25 MPH COLLISION WITH A CHROME F250 TRUCK MIRROR W/NO DAMAGE TO THE BLAZER MIRROR OR ASSEMBLY. THE GMC "PROFESSIONAL GRADE" (TERM USED VERY LOOSELY HERE) TRUCK THAT I NOW OWN WON'T EVEN STAND UP TO A MINOR CLIP ON THE SIDE OF THE GARAGE AT SLOW SPEED. ENGINEERING DEFECTS ARE 1) MIRROR ACTUATOR ASSEMBLY IS OF POOR QUALITY AND/OR WORKMANSHIP AND 2) MIRROR ASSEMBLY MOVES UP SLIGHTLY WHEN PIVOTING, WHICH PROBABLY CONTRIBUTED TO THE BREAKAGE AT SUCH SLOW SPEED (WAS SLOWLY BACKING UP AN INCLINE INTO THE GARAGE). APPARENTLY, I WAS NOT CONVINCING ENOUGH TO GM THAT THEY HAVE A PROBLEM WITH FLIMSY MIRRORS - PERHAPS NHTSA AND BBB CAN BE MORE PERSUADING. ALL I ASKED FOR WAS THAT THEY COVER THE FLIMSY PLASTIC ACTUATOR AND PART OF THE $93 LABOR QUOTED FOR THE JOB BY THE DEALER. THE MIRROR ITSELF I HAVE NO QUALMS PAYING FOR. OLD PARTS ARE AVAILABLE ON THE TRUCK - I PLAN TO DRIVE MY NEARLY NEW TRUCK "AS IS" FOR A WHILE AS A SYMBOL OF GM'S POOR QUALITY OF WORKMANSHIP AND POOR CUSTOMER SERVICE. I ALSO PLAN ON TELLING AS MANY PEOPLE AS POSSIBLE ABOUT HOW FLIMSY GM MAKES THEIR VEHICLES AND HOW NON-EXISTENT THEIR CUSTOMER SUPPORT IS. *TR

WHEELS
2 complaints
No accident happened as the wheel was never installed due to not meeting the load weight capacity rating of the vehicle. The wheel is marked max load 1150kg (2230 per axle) and the vehicle weight loading label shows the rear axle capacity at 2706kg. The wheel is also marked as SAE J2530 compliant but does not meet J2530 section 3.5 due to the low load capacity. These wheels are widely available in the aftermarket and list most of the 2000-2010 GM 2500HD/3500 pickups as the application but do not meet load capacity on any of them. Please note that the VIN is for a typical 2008 Sierra 2500HD pickup in a scrap yard. I do not own that vehicle. It is a weight label photo from Hollander parts finder on that pickup.

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

TOOK TRUCK TO GMC DEALER FOR SERVICE & REQUESTED THAT THEY CHECK THE LOWER FRONT BALL JOINTS. THEY INDICATED THAT THE BALL JOINTS HAD ONE QUARTER OF AN INCH OF VERTICAL PLAY AND WERE INDEED LOOSE & NEEDED REPLACEMENT. I HAVE EARLIER GMC TRUCKS WITH OVER 200,000 MILES AND HAVE NOT HAD WORN LOWER BALL JOINTS. I BELIEVE THAT THE LOOSENESS IS DUE TO THE BALL JOINT PULLING APART. THE WEAR WAS NOT SIDE TO SIDE AS WOULD BE EXPECTED. I WANT TO REPAIR THIS DEFECT SO AS TO AVOID A CATASTROPHIC FAILURE OF THE FRONT SUSPENSION. I WANT TO USE OEM PARTS BUT I AM CONCERNED THAT THESE BALL JOINTS ARE DEFECTIVE.

Additionally, the vehicle made abnormal sounds, jerked, and stalled while driving. The vehicle was taken back to the dealer, and there was smoke coming from under the hood. Upon inspection, the dealer discovered that the catalytic convertor was extremely hot and glowing red. The dealer determined that the exhaust system and catalytic convertor needed to be replaced. The vehicle was then towed to the residence. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was 151,071.

POWER DOOR LOCK FAILED ON DRIVER DOOR. YOU CAN NOT OPEN DOOR WITH OUT LIFTING HAND LATCH. THIS IS VERY DANGEROUS-- MEANING YOU CAN NOT OPEN DOOR BY DOOR HANDLE-- THERE IS NO OVERRIDE LIKE PROVIDED ON OTHER VEHICLES. OTHER DOOR FAILED 2 MONTHS LATER. TRUCK LOCKS AND UNLOCKS DOORS WHEN MOVING SHIFTER FROM PARK TO DRIVE, THERE IS NO PROGRAM OPTION TO DELETE THIS OPTION. SO YOU LOCK AND UNLOCK DOORS EVERY TIME YOU SHIFT TRUCK TRANSMISSION TO PARK OR IN DRIVE. THIS IS NOT NEEDED IN MY CASE, SINCE YOU CAN MANUALLY DO SAME. THIS IS MANUFACTURE DEFECT AND SHOULD BE RECALLED. *TR

TRUCK SHAKES BETWEEN 45 AND 60. DOES IT ALL THE TIME. TOOK TO GMC DEALER AND THEY CHECK IT OUT AND SAID IT WAS THE WAY THE TRUCK WAS GET USED TO IT. CALLED DETROIT AND GOT THE SAME THING. IT'S NOT RIGHT. IT ALL STARTED WITH AROUND 14,000 MILES .THE TRUCK DIDN'T DO IT AT ALL UNTIL THEN. THE SERVICE STATION THAT I USE TO SERVICE IT FOUND THE TIRES TO BE OUT OF ROUND AND THE SIDEWALLS WERE COMING UNDONE. PUT A NEW SET OF TIRES ON AND IT HELPED A LITTLE BIT BUT NOT A GREAT DEAL. THEY ALSO TOLD ME TO PUT WEIGHT IN THE BOX TO HELP. I TRIED AND IT DIDN'T HELP. ALL I WANT IS THE TRUCK MADE RIGHT. *TR
