THE REAR LEAF SPRINGS POP AND GROAN WHILE THE VEHICLE IS IN MOTION AT LOW SPEEDS, ESPECIALLY WHILE TURNING IN REVERSE. GM KNOWS ABOUT THE PROBLEM AND EVERY TIME I GO TO THEM THEY SAY IT'S NORMAL.

STEERING
I HAVE HAD THE LOWER STEERING ARM REPLACED THREE TIMES DUE TO A BAD BUSHING. ONCE UNDER WARRANTY & TWICE I HAD TO PAY FOR IT WHICH IS OVER $300.00 EACH TIME. THIS IS NOT AN UNCOMMON PROBLEM WITH THE CHEVROLET & GMC TRUCKS. THIS IS ONLY NOTICEABLE WHILE IN MOTION.

SUSPENSION
THE TRUCK STARTS TO VIBRATE TERRIBLY WHEN IN MOTION AT HIGHWAY SPEEDS ANYWHERE BETWEEN 70-85, EVEN IF ON NEW SMOOTH SET OF HIGHWAY TRUCK WILL STILL VIBRATE. I HAVE COME TO THE CONCLUSION THAT ITS THE TRUCK AND NOT THE ROADS.

I BOUGHT THIS TRUCK BRAND NEW AND I CAN ALWAYS REMEMBER HEARING LOUD POPS COMING FROM THE DASH AREA ON A REGULAR BASIS. FOR SEVERAL THOUSAND MILES, THERE WAS NO VISUAL DAMAGE AS A RESULT OF THESE POPS. AROUND 60,000 MILES, HOWEVER, I BEGAN TO. NOTICE A CRACK IN THE DASHBOARD NEAR THE PASSENGER AIR BAG. AS I CONTINUED TO DRIVE THE TRUCK, I STILL HEARD THE OCCASIONAL POP AND ANOTHER CRACK SOON APPEARED ABOVE THE INSTRUMENT CLUSTER. MORE MIKES DRIVEN, MORE POPS, AND MORE CRACKS. AS ANYONE WOULD DO, I TOOK MY TRUCK INTO THE LOCAL GM DEALERSHIP TO LET THEM KNOW THAT SOMETHING WAS WRONG WITH THE DASHBOARD. I ALWAYS USED A SUNSHADE WHEN PARKING OUTSIDE AND I KEPT IT PARKED IN THE GARAGE AT HOME. I ALSO KEEP MY TRUCK MAINTAINED VERY WELL, AS I CAN'T STAND A DIRTY AND NEGLECTED VEHICLE. SINCE IT HAD BEEN WELL-MAINTAINED AND WAS NEVER DRIVEN HARD, I EXPECTED GM TO SEE THE DAMAGE AND REPLACE IT UNDER WARRANTY. TO MY DISMAY, HOWEVER, THEY SAID THAT DUE TO THE AGE AND MILEAGE, THAT THEY WOULD NOT BE ABLE TO OFFER ANY ASSISTANCE. GM QUOTED ME AROUND $1200 TO REPLACE THE DASHBOARD IF I WANTED TO GET RID OF THE CRACKS. ASTONISHED THAT GM WOULD NOT WARRANTY AN OBVIOUS FAULTY ITEM, I THEN SEARCHED ONLINE TO SEE IF ANYONE ELSE HAD THE SAME PROBLEM. I QUICKLY FOUND OTHERS IN FORUMS, YOUTUBE VIDEOS, AND ON FACEBOOK THAT HAD THE EXACT SAME PROBLEM AS MYSELF, WITH CRACKS IN THE EXACT SAME PLACES AND VERY SIMILAR RESPONSES FROM GM WHEN THEY TRIED TO HAVE THE ISSUE RESOLVED. I FOUND A GROUP ON FACEBOOK DEDICATED TO THIS EXACT PROBLEM AND IT IS CONSISTENT IN '07-'13 MODEL GM TRUCKS AND SUVS. AFTER BEING DENIED ASSISTANCE BY GM, HAVING SOME MECHANICAL KNOWLEDGE, AS WELL AS THE DESIRE TO CONTINUE DRIVING THIS TRUCK LONGER, I REMOVED THE DASHBOARD ONLY TO FIND CRACKS IN THE DASHBOARD WHERE THE SCREWS FASTENED IT IN PLACE, AS WELL AS CLIPS BROKEN OFF THAT WERE MEANT TO HOLD IT DOWN INTO PLACE.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
AS WELL AS HAVING VERY POOR VISABILITY, THE HAEDLIGHT BULBS ON MY TRUCK HAVE BLOWN OUT 5 TIMES IN ONLY TWO YEARS. THERE IS OBVIUOSLY SOMETHING WRONG WITH SOMETHING BESIDES THE BULBS.I AM GOING BROKE REPLACING THEM. I CALLED THE DEALER AND WAS TOLD THAT IT WOULD COST ME 115.00 AN HOUR JUST TO LOOK AT THE TRUCK. I WOULD RATHER GIVE THE TRUCK BACK, THAN PAY TO HAVE A PROBLAM THAT IS OBVIOUSLY A MANUFACTURING DEFECT, FIXED. THE LIGHTS HAVE WENT OUT BOTH WHILE MOVING, AND STATIONARY.

STARTED MY TRUCK ON 7/30/17 AND HAD NO COLD AIR BLOWING FROM THE VENTS. DROVE IT FOR THE DAY AND STILL NOTHING. TOOK IT INTO THE DEALER ON 8/2/17 AND RECEIVED THE DIAGNOSIS OF A CRACKED AC CONDENSER. THE FIX IS NOT POSSIBLE FOR 6-8 WEEKS BECAUSE THERE IS A NATIONAL BACKORDER ON A REPLACEMENT CONDENSER FROM GMC. THIS IS A DESIGN ISSUE AND NOT A WARE AND TEAR ISSUE. THE DEALERSHIPS WANT THE OWNERS TO PAY FOR IT EVEN THOUGH THEIR DESIGN IS AT FAULT TO BEGIN WITH.

SEATS
MY DRIVER'S SEAT BECAME LOOSE APPROXIMATELY 2 WEEKS AGO (7/17/17). IT HAS BECOME PROGRESSIVELY WORSE, TO THE POINT WHERE I CAN FEEL MY SEAT SHIFTING WHEN I TURN OR ACCELERATE. I AM WORRIED THAT IN THE EVENT OF A WRECK, MY SEAT MAY BECOME A PROJECTILE. I TOOK MY TRUCK INTO THE DEALERSHIP IN WACO, TX ON 7/31/17, AND THE DEALERSHIP HAS STATED (TODAY, 8/1/17) THAT THIS CONDITION IS NOT COVERED BY ANY WARRANTY PROGRAM, WHICH I FIND DISAPPOINTING AND FRUSTRATING. I HAVE READ MULTIPLE REPORTS OF THIS SAME CONDITION IN GM TRUCKS FROM 2014 - 2015 YEAR MODELS.

WHEELS
CHROME WHEEL CORROSION. CRITICAL LOCATION AROUND VALVE STEM CREATING AIR LEAK IN VALVE STEM. COULD CREATE LOW ENOUGH PRESSURE TO EFFECT HANDLING IN EMERGENCY SITUATION. LUCKILY MINE WAS A SLOW LEAK, BUT THE ONLY FIX IS WHEEL REPLACEMENT AT EXTREME COST AND A LENGTHY REPLACEMENT PROCESS LEAVING THE OWNER WITH CHOICE OF UNSAFE USE, OR LOSING USE OF THE VEHICLE DURING THE PROCESS. INITIAL FIRST AID WAS TO CLEAN THE STEM HOLE OF CORROSION, USE A SEALANT AROUND THE NEW VALVE STEM, WITH NO GUARANTEE OF A SAFE FIX AND AN UPCOMING 2 WEEK TRIP TO UPPER ONTARIO CANADA IN FULLY LOADED VEHICLE.

SERVICE BRAKES
BRAKE FAILURE FOR THE SECOND TIME ON THE VEHICLE. ORIGINAL BRAKE LINES WERE REPLACED 7 OR 8 YEARS AGO DUE TO FAILURE AT MY OWN COST (RUSTED LINES, LEADING THEM TO FAIL AS THE BRAKES WERE APPLIED), ALL LINES WERE REPLACE WITH GM REPLACEMENT LINES BY A QUALIFIED TECHNICIAN. ORIGINAL FAILURE RENDERED THE BRAKES 0% OPERATIONAL, GRAVITY (UPHILL) WAS THE ONLY THING THAT STOPPED THE VEHICLE. THE MOST RECENT FAILURE (ON JULY 29, 2017) AFFECTED THE BRAKE LINE RUNNING TO THE FRONT-RIGHT CALIPER, LINE FAILED WHERE IT CROSSED OVER THE SKID PLATE NEAR THE CENTER-LINE OF THE VEHICLE UP FRONT BY THE LOWER RADIATOR SUPPORT. LINE FAILED DUE TO CORROSION. REAR BRAKES APPEAR TO BE WORKING BUT ARE NOT SUFFICIENT TO STOP THE VEHICLE IN A SAFE MANNER. NO ACCIDENT OCCURRED, LINE FAILED AS APPROACHING A LIGHT TURNING RED WHILE GOING UPHILL, ROLLED THROUGH THE INTERSECTION PRIOR TO THE LIGHT TURNING GREEN FOR CROSSING TRAFFIC AND WAS ABLE TO STOP THE VEHICLE AS IT DRIFTED TO A STOP UPHILL. THE QUALITY OF THE GM BRAKE LINES ARE VERY SUSPECT TO SAY THE LEAST. THE BRAKE LINES ARE DANGEROUS AND SEEM TO BE MORE SUSCEPTIBLE TO CORROSION THAN ANY OTHER BRAKE LINE ON ANY OTHER VEHICLE I'VE EVER OWNED, OR ANY OF MY FRIENDS OR FAMILY HAVE EVER OWNED. I CAN ONLY IMAGINE IF THE LINES FAILED UNDER DIFFERENT CIRCUMSTANCES (WHILE TOWING THOUGH MOUNTAINS WHILE GOING DOWNHILL FOR EXAMPLE, THIS WOULD BE A LIFE-THREATENING SITUATION). PLEASE DETERMINE IF THESE LINES ARE FAULTY FOR THE SAKE OF OTHERS WITH THESE VEHICLES, AND THE SAKE OF OTHER MOTORISTS THAT COULD BE IMPACTED WHEN THE BRAKES ON THIS LARGER VEHICLE FAIL. IF THEY ARE FOUND TO BE FAULTY OWNERS SHOULD BE NOTIFIED THAT THESE BRAKE LINES ARE SUBPAR, AND THAT THE MANUFACTURER'S REPLACEMENT LINES ARE ALSO SUBPAR.
