2015 GMC Yukon Complaint Log

PIPING IN THE STEERING COLUMN. NOT CONSISTENT. HAPPENS DAILY

OUR 2015 YUKON XL DENALI HAS BEEN IN FOR REPAIR SERVICE FOR 41 DAYS SINCE PURCHASED NEW 3/23/15. THE CAR HAS STALLED WHILE IN MOTION WITH MY WIFE AND THREE DAUGHTERS IN THE VEHICLE TWICE AND BEEN UNRESPONSIVE TO THROTTLE INPUT 3 ADDITIONAL TIMES. THE STALL OCCURRED ONCE WHILE TURNING LEFT ACROSS TRAFFIC AND ANOTHER TIME WHILE TURNING RIGHT AND MERGING WITH TRAFFIC! THE PROBLEM IS INTERMITTENT AND GMC HAS NEVER BEEN ABLE TO REPLICATE IT. THEY HAVE GIVEN US THE SHOULDER SHRUG, "I DON'T KNOW WHAT TO TELL YOU, WE CAN'T REPLICATE IT" LINE, SO HERE ARE YOUR KEYS. NO WARNING INDICATORS, NO SIGNS IT MAY HAPPEN, AND NO WAY TO PULL UP THE ISSUE WITH THEIR DIAGNOSTICS...HUGE SAFETY CONCERN AND EACH TIME THEY HAVE HANDED US THE KEYS BACK AFTER 7 DAYS (THEIR STANDARD ALLOTTED TIME TO HAVE A LOANER OUT) WITHOUT ANY PROACTIVE ESCALATION TO FIND ROOT CAUSE OR CONCERN FOR MY FAMILY'S SAFETY. THE LAST TIME WE TOOK IT IN, THEY HAD IT FOR 8 DAYS AND COULD NOT REPLICATE THE ISSUE. WE SIGNED OUR SERVICE PAPERWORK AND I ESCALATED TO THE SERVICE MANAGER BEFORE LEAVING. AFTER TELLING HIM WE WOULD BE PURSUING BUYBACK, HE MIRACULOUSLY HAD AN IDEA IT MAY BE RELATED TO A WIRING HARNESS ISSUE. THIS WAS BASED OFF HIS EXPERIENCE WITH A SIERRA PICKUP (5.3L, NOT OUR 6.2L) THAT HAD SIMILAR BEHAVIOR. WE LEFT THE VEHICLE AND, WOULDN'T YOU KNOW IT, THEY REPLACED A WIRE AND "HAVE REASONABLE CONFIDENCE" IT RESOLVED THE ISSUE. TWO WEEKS LATER, IT'S BACK IN THE SHOP FOR KEY FOB NOT DETECTED (AFTER ALREADY DRIVING). TRUCK IS IN GEAR AND YOU CANNOT MOVE...ANOTHER HUGE SAFETY CONCERN. IT'S A DUD. WE HAVE ALSO HAD TO HAVE ALL 8 INJECTORS REPLACED DUE TO ROUGH IDLING AND THE STEERING GEAR REPLACED FROM FAULTY MANUFACTURING THAT CREATES A CLICKING WHILE TURNING THE WHEEL, THE CAR IS AT THE DEALER AND WE WILL NOT BE TAKING IT BACK. WE ARE GOING THROUGH THE OFFICAL BUY-BACK PROCESS WITH GMC.

VERY CONCERNED ABOUT MY 2015 YUKON XLT. THE VEHICLE'S GEAR SHIFTED TO A NEUTRAL OF VERY LOW GEAR (NOT VERY SURE) AS I WAS DRIVING DOWN A LONG HILL NEAR BIRMINGHAM, AL. IT FELT LIKE IT WENT TO FIRST GEAR, BUT AT THE SAME TIME IT DID NOT SLOW THE VEHICLE DOWN, ALMOST FELT LIKE THE GEAR WAS GRINDING. THE TRUCK DID NOT CATCH BACK INTO NORMAL GEAR UNTIL THE VEHICLE LEVELED BACK AT THE BOTTOM OF THE HILL. (IT WAS EXTREMELY SCARY AND WORRISOME EVER SINCE THEN, THE TRANSMISSION WILL NOT SHIFT SMOOTHLY.

TRANSMISSION HAS BEEN CLUNKY AND JERKY FROM FROM PURCHASE. THE VEHICLE VIBRATES BETWEEN 30 - 35 MILES PER HOUR WHEN SHIFTING. THE VEHICLE LURCHES FORWARD WHEN ACCELERATING AS IF IT HAS DIFFICULTY DOWN-SHIFTING. THE PROBLEM IS PRESENT FROM SIMPLY BACKING UP OUT OF THE DRIVEWAY, MODEST SPEEDS ON CITY STREETS, OR ON THE HIGHWAY. WHEN BROUGHT BACK TO THE DEALER, THEY CLAIMED IT WAS A SOFTWARE ISSUE AND "REFRESHED" THE SOFTWARE. THE PROBLEM HAS NOT GONE AWAY AND DID NOT IMPROVE BY THIS SOFTWARE CORRECTION. MY INTERNET RESEARCH INDICATES THAT THIS IS A COMMON PROBLEM WITH THE NEW 8-SPEED TRANSMISSION FOR THE 2015 YUKON DENALI AND CADILLAC ESCALADE.

PASSENGER BRAKE LIGHT DOES NOT WORK. WE HAVE HAD PROBLEMS WITH IT SINCE DAY ONE. WE TOOK IT BACK SEVERAL TIMES BUT STILL DOESN'T WORK.

OUR VEHICLE HAS A SIGNIFICANT VIBRATION IN V4 MODE WHEN TRAVELING BETWEEN 45-65 MPH AND ABOVE. THE VIBRATION IS ALSO ACCOMPANIED BY INCREASED CABIN PRESSURE. THESE ISSUES ARE CAUSING HEADACHES, NAUSEA, DIZZINESS, AND ARE FURTHER EXACERBATING MY WIFE'S MULTIPLE SCLEROSIS. WE ALSO HAVE A POPPING SOUND COMING FROM THE REAR OF THE VEHICLE'S SUSPENSION WHEN TURNING THAT MAKES US FEEL UNSAFE. THE VIBRATION STARTED RIGHT AFTER WE TOOK DELIVERY OF THE CAR AND HAS ONLY GOTTEN WORSE. WE BOUGHT THE CAR IN APRIL 2015 AND THE ISSUE CONTINUES UNFIXED TO THIS DAY. THE POPPING NOISE STARTED ABOUT 3-4 WEEKS AGO AND IT SOUNDS LIKE A SUSPENSION COMPONENT. OUR AC RECIRCULATING FEATURE ALSO DOES NOT WORK AND IT ALLOWS HARMFUL EXHAUST SMOKE IN.

I HAVE A 2015 YUKON DENALI AND I WAS DRIVING 65 ON THE HIGHWAY AND THE ENGINE SHUT DOWN COMPLETELY. A WARNING MESSAGE SAID ENGINE POWER FAILURE. I HAD 4 CARS AND AN 18 WHEELER BEHIND ME AT THE TIME. I MANAGED TO PUT THE VEHICLE IN NEUTRAL AND COAST TO THE SIDE OF THE ROAD ONTO A MEDIAN. IT WAS TOWED TO THE DEALERSHIP WHERE THEY STARTED TRYING SAY IT MIGHT HAVE BEEN BAD GAS. THEN I WAS TOLD I CRACKED VALVE AND THEY ALREADY HAD ONE OTHER JUST LIKE THIS, THEN 1 DAY LATER AFTER A TECH LEVEL 2 AND A SHOP FORUM LOOKED AT IT, AND A CONVERSATION WITH A GM PAC REP, GM APPROVED A COMPLETE ENGINE REPLACEMENT! I WAS SHOCKED. I'VE HAD THE SAME 4-WHEEL DRIVE ISSUES EVERYONE ELSE HAS. I'VE ALSO HAD A/C PROBLEMS, STEER WHEEL POPPING NOISES, SUNROOF LOUD WIND NOISES. MY SEAT SHIFTS WHEN I DRIVE IT. THE A/C SEATS DON'T COOL PROPERLY, WHICH I FOUND OUT WHEN THEY PUT ME IN A LOANER YUKON THAT WORKED FINE. THE SPEEDOMETER GAUGE ALSO DIDN'T WORK FOR 2 DAYS, WHICH I HAVE A PICTURE OF AND RECEIVED A WARNING TICKET FOR WHEN I WAS PULLED OVER BY AN OFFICER NOT KNOWING WHAT SPEED I WAS GOING. I PASSENGER STEP GUARD DOESN'T ALWAYS RETRACT PROPERLY. MY UNIT WAS PURCHASE MAY 2014 AND WAS ONE OF THE FIRST 4 X 4 UNITS THAT WAS PRODUCED AND HAS HAD CONSTANT PROBLEMS. GM KEEPS DENYING A BUYBACK, THEN NO TRADE ASSISTANCE, THEN NOW HAS OFFERED AN EXTENDED WARRANTY. THIS PARTICULAR VEHICLE I HAVE IS NOT SAFE FOR MY FAMILY TO BE RIDING IN. I CAN'T TRADE IT IN OR SELL IT TO ANYONE ELSE KNOWING THE PROBLEMS IT HAS. THE DEALER WON'T EVEN TAKE IT BECAUSE THEY KNOW THE PROBLEM THAT THEY ARE DEALING WITH. *TR

THE NEW 2015 VEHICLE FREEZES UP IN FULL TIME 4WD MODE AND WILL NOT SHIFT OUT. THE DEALER INDICATES THAT IT IS A "KNOWN PROBLEM BY GM" AND THAT THEY ARE "WORKING ON IT". THEIR FIX AT THIS POINT IS TO HAVE YOU RUN THE VEHICLE IN 2WD MODE WHICH IS AN OBVIOUS SAFETY ISSUE DURING OUR WINTER MONTHS AS IT IS THEN A REAR WHEEL DRIVE VEHICLE BEING DRIVEN ON ICY ROADS.THE OTHER FIX IS TO RUN IT IN 4WD MODE BUT TURN IT INTO 2WD MODE EVERY TIME YOU TURN THE VEHICLE OFF. OBVIOUSLY, MANY DRIVERS WILL FORGET TO DO THIS AND THEREFORE MY FAMILY AT TIMES IS JUST RUNNING IT IN 2WD MODE THEREBY INCURRING A RISKY DRIVING SITUATION. DESPITE NUMEROUS DISCUSSION, I HAVE NOT BEEN ABLE TO GET ANY INFORMATION ON WHEN THE VEHICLE WILL BE FIXED. *TR

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING 35 MPH, ALL THE WARNING LIGHTS ILLUMINATED AND THE FOUR WHEEL DRIVE LOW INDEPENDENTLY ACTIVATED. THE VEHICLE WAS TOWED TO A DEALER. THE TECHNICIAN DIAGNOSED THAT THE BODY CONTROL MODULE NEEDED TO BE REPAIRED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE BODY CONTROL MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 5,000. THE VIN WAS UNAVAILABLE.

THE HEATED SEATS DO NOT HEAT UP. THE CAR WAS IN THE SHOP FOR THIS PROBLEM WITHIN THE 1ST 1000K MILES. THEY TOLD ME TO "BE PATIENT" AND THEY'LL GET WARM. THE CAR HAS BEEN IN THE SHOP A TOTAL OF 7 DAYS FOR THE SEATS NOT WORKING AND I HAVE YET TO GET IT RESOLVED. EMAILED THE CEO OF GM AND GOT A PHONE CALL FROM A PERSON WHO STATED GM CONSIDERS THE SEATS ARE WORKING ALTHOUGH THEY DON'T WORK MOST OF THE TIME AND WHEN THEY DO GET SOME SORT OF HEAT (THE SHOP TOLD ME THEY GOT ONE SEAT TO HEAT UP TO 87 DEGREES! WOW!) IT IS INTERMITTENT AND UNEVEN. THE SEATS HAVEN'T WORKED AT ALL IN THE LAST 3 WEEKS AND THE AVERAGE TEMP HASN'T BEEN ABOVE 32 DEGREES. I SPENT A FORTUNE FOR THIS CAR AND I CAN'T GET ANYONE AT THE DEALERSHIP NOR IN DETROIT TO ACKNOWLEDGE THIS CAR IS A LEMON OR THEY HAVE A DESIGN FLAW SINCE THEY SWITCHED TO BLOWERS FROM HEATED COILS. I AM SUPPOSING THE A/C IN THE SEATS WON'T WORK WHEN IT'S 100 OUTSIDE AND I'LL BE TOLD TO BE PATIENT AGAIN. I'VE ASKED FOR MY $$ BACK AND I'LL RETURN THE CAR. IT'S GOT 4,200K MI AND I AM SO DONE WITH THIS LEMON BUCKET. *TR

WHEN THE CAR IS AT IDLE IN DRIVE IT BECOMES VERY ROUGH (FLUCTUATES UP AND DOWN). THIS HAPPENS ON AND OFF AND I HAVE NO CHECK ENGINE LIGHT ON. SOMETIMES THE CAR EVEN FEELS LIKE IT IS GOING TO STALL OUT. I HAVE HAD IT INTO THE DEALER AND THEY ADMITTED THEY FEEL IT AS WELL. THEY TRIED ADJUSTING THE MOTOR MOUNTS AND THAT DID NOT DO IT. AFTER HAVING IN THE DEALER FOR SEVERAL DAYS THEY CALLED ME AND SAID THEY CAN'T FIND THE ISSUE. THEY TOLD ME THEY WENT INTO ANOTHER 2015 GMC YUKON SLE AND STARTED FEELING THE SAME ISSUE. IT WAS STATED TO ME I MIGHT HAVE TO WAIT FOR MORE COMPLAINTS ON THE VEHICLE TO GET TO THE ROOT OF THE ISSUE. IT CONTINUES TO IDLE ROUGHLY AND I WANT TO GET THIS RESOLVED.

ALL DOORS ON THE VEHICLE LOCK WHEN TRANSMISSION IS PUT INTO GEAR AND ALL DOORS LOCK SEVERAL SECONDS AFTER DOOR IS SHUT WITH ENGINE OFF. THE AUTOMATIC DOOR LOCKS CAN NOT BE DEACTIVATED BY MYSELF OR BY THE DEALER. I FIND THIS BOTH A SAFETY ISSUE AND A INCONVENIENCE. AS A COMMERCIAL TRUCK DRIVER DRIVEN MILLIONS OF MILES I HAVE BOTH WITNESSED AND HAVE DIRECTLY BEEN INVOLVED WITH TRYING TO GET PEOPLE EXTRACTED FROM WRECKS. DUE TO LOCKED DOORS IN SEVERAL CASES THIS HAS NOT BEEN POSSIBLE WITHOUT BREAKING A SIDE GLASS AND PHYSICALLY UNLOCKING THE DOOR FROM INSIDE OF THE VEHICLE. IN ONE ACCIDENT TWO PEOPLE WERE UNCONSCIOUS AFTER A CRASH WITH THE ENGINE RUNNING AND A FIRE UNDER THE HOOD, THE DOORS WERE LOCKED. IN ANOTHER, A PERSON WAS HAVING AN EPILEPTIC SEIZURE AFTER A CRASH AND AGAIN DOORS WERE LOCKS. IN THE LAST EXAMPLE A MAN DIED AFTER DRIVING INTO A CANAL, RESCUERS WERE UNABLE TO BREAK THE GLASS IN TIME TO SAVE THE DRIVER. I SHOULD HAVE THE ABILITY TO DECIDE WHETHER TO HAVE THE DOORS AUTOMATICALLY LOCK; NOT THE MANUFACTURER. THE 2013 AND OLDER GMC TRUCKS THE AUTOMATIC DOOR LOCKS CAN BE DEACTIVATED BUT 2014 AND NEWER GM REFUSED TO RELEASE THE PROGRAM TO THE DEALERS OR PUBLIC SO I HAVE NO OPTION BUT TO DRIVE WITH LOCKED DOORS. I AM ASKING TO HAVE GM RELEASE THE PROGRAM TO ACHIEVE DISABLING THE AUTOMATIC DOOR LOCKS. *TR

TRANSFER CASE ENGAGED INTO 4WD WHILE DRIVING WITH TOUCHING ANY OF THE CONTROLS. NOW IT WON'T SWITCH OUT. SERVICE 4WD LIGHT APPEARS. *TR

TURNED ON CAR, SERVICE 4 WHEEL DRIVE MESSAGE ON DISPLAY. CAR WILL NOT MOVE. STRANDED WITH SMALL CHILDREN FOR 1 HOUR WAITING FOR A TOW. ONLY 616 MILES ON THE CAR - HAD FOR A WEEK. WHY ON EARTH WAS THE RECALL NOT PERFORMED AT THE DEALERSHIP PRIOR TO SELLING A $70,000 VEHICLE? *TR

AFTER OWNING THE 2015 YUKON DENALI FOR 6 MONTHS, I HAVE TO SAY THIS VEHICLE HAS ITS FLAWS. THE 4WD SYSTEM IS IN FOR SERVICE ALREADY AFTER 9000 MILES. NOT THE KIND OF QUALITY I WOULD HAVE EXPECTED ON AN $80,000 SUV. AT THE MOMENT, THE VEHICLE IS ONLY A 2 WD SYSTEM AND SEEMS VERY DIFFICULT TO DRIVE AND TURN. ALSO, THE INTELLILINK SOFTWARE IS VERY "BUGGY" AND NEEDS MANY UPDATES. ON SEVERAL OCCASIONS, THE ENTIRE TOUCHSCREEN WILL GO BLANK WHILE DRIVING DOWN THE ROAD. THIS IS CAUSE FOR CONCERN AND IS A MAJOR DRIVING DISTRACTION. *TR

I WAS BACKING OUT OF PARKING SPACE IN THE MALL PARKING LOT WHEN THE SERVICE LIGHT CAME ON. IT STATED SERVICE 4WD. THE TRUCK WAS VERY HARD TO STEER AND WOULDN'T CHANGE INTO 2 WHEEL DRIVE I WAS 40 MILES FROM HOME AND BURNED OVER A 1\4 TANK OF GAS. WITH LESS THAN 6000 MILES I MUST SAY THIS ISN'T HOW I EXPECT A $60,000 TRUCK TO PERFORM. *TR

VEHICLE HAS A TERRIBLE VIBRATION. HAS BEEN TO DEALER 7 TIMES, FOR A TOTAL OF 4 WEEKS. A GM ENGINEER HAS LOOKED AT IT TWICE. THEY HAVE REPLACED RING/PINION, DRIVESHAFT, AXLE .. TRIED IT WITH 4 SETS OF TIRES/WHEELS. LAST IDEA WAS TO REPLACE SHOCKS, STRUTS, SWAY BARS WITH HAND BUILT PARTS, CUT BRACKETS OFF CAR AND WELD NEW BRACKETS ON. WHEN LIABILITY WAS BROUGHT UP, THEY CHANGED THEIR STORY. THERE IS A LARGER ISSUE AS WAS RELAYED BY ENGINEER TO SERVICE MANAGER AT DEALERSHIP. ISSUE IS WITH ALL 2015 TAHOE, YUKON, ESCALADES. IN AN EFFORT TO PREVENT ROLL OVERS, THEY DESIGNED THE FRAME AND BODY MOUNTS TOO STIFF. THERE ARE 40 ENGINEERS WORKING ON ISSUES, THEY HAVE NO SOLUTIONS THAT WORK ACROSS THE BOARD. ACCORDING TO ENGINEER, GM IS KEEPING AN EYE ON HOW MANY UNITS THEY HAVE TO BUY BACK, OR TRADE FOR ... IF NUMBER IS LOW ENOUGH, THEY WILL NOT MAKE ANY CHANGES TO DESIGN. I WOULD LIKE TO SCHEDULE A MEETING NEXT WEEK TO DISCUSS THIS ISSUE AND THE LARGER ISSUE IN PERSON. SINCE THEY ARE REFUSING TO BUY BACK MY VEHICLE, I AM TURNING MATTER OVER TO ATTORNEY. *TR

THIS IS THE SECOND TIME THE FOLLOWING OCCURRED. (OCT 27,2014 AND NOW ON NOV. 5,2014). WHEN I WENT TO DRIVE THE CAR, SUDDENLY THE CAR DID NOT TURN PROPERLY. IF I MADE A SHARP TURN, IT SOUNDED LIKE THE FRONT WHEELS WERE RUBBING. THE CAR WAS IN 2 WHEEL AUTO. I IMMEDIATELY CALLED THE SALESMAN AND EXPLAINED THE SITUATION. I DROVE THE CAR ON THE HIGHWAY (65MPH) TO DEALERSHIP. DAY LATER, LOOSE WIRE IN TRANSFER CASE. EVERYTHING FINE. SAME THING OCCURS ON NOV. 5TH AND THE SALESMAN TELLS ME TO TAKE A VIDEO, WHICH I DO, AND BRING THE CAR IN. TODAY I AM TOLD IT WAS THE COMPUTER PROGRAM THAT WAS THE PROBLEM. THE SALESMAN CONFIRMS THAT THE AUTO WAS IN 4 WHEEL DRIVE WHEN I BROUGHT THE CAR IN BUT THE RECEIVING AND DELIVERY SERVICE TECHNICIAN NOW SAYS IT WASN'T. HE SAID THE 4WD LIGHT WAS NOT ON AND HE ONLY FELT A LITTLE BIT OF A ROUGH RIDE WHEN I DROPPED IT OFF. HE ALSO TOLD ME THAT THE STATE OF VIRGINIA DOES NOT HAVE A LEMON LAW, WHICH HE BACK TRACKED AFTER I CALLED HIM ON IT. OTHER PROBLEMS WITH CAR. NAV/RADIO/BACKUP CAMERA WENT BLANK ON NOV. 4TH. THERE IS A WHISTLE NOISE ON THE TOP OF THE DRIVERS SIDE DOOR. THE RIDE IS SUBSTANDARD TO MY OLD 2007 GMC YUKON XL DENALI, WHICH I BOUGHT NEW AND HAD 197K MILES. YOU FEEL EVERY PEBBLE OR ROAD IMPERFECTION. YOU GET THE TYPICAL RESPONSE AS IF THIS WAS A $5,000 USED CAR AND NOT AN $78,000.00 PREMIUM SUV. *TR

DOOR LATCH IN THE LOCKED POSITION WHILE DOOR IS OPEN. CAR COMPUTER THOUGHT THE DOOR WAS CLOSED AND DOOR WAS OPEN. HAPPENED TWO TIMES IN ONE DAY. VERY SERIOUS PROBLEM IS DRIVER IS ALLOWED TO DRIVE WITH CHILDREN IN THE BACK SEAT WITH NO WARNING THAT THE DOOR DID NOT CLOSE. *TR

I HAVE A BRAND NEW 2015 YUKON DENALI (SHORT WHEEL BASE) WITH LESS THAN A THOUSAND MILES AND A "SERVICE 4WD" MESSAGE THAT HAS APPEARED TWICE RENDERING THE CAR EXTREMELY UNSAFE AND UN-DRIVABLE FOR A LONG DISTANCE AND HAVING TO HAVE IT TOWED TO THE DEALER TWICE. A SOFTWARE UPDATE WAS DONE ON THE CAR THE FIRST TIME, ONLY RESOLVED THE ISSUE FOR A FEW WEEKS, THE ISSUE RE-OCCURRED AFTER 3 WEEKS. WHEN TURNING THE VEHICLE ON THE DASH GIVES THE MESSAGE "SERVICE 4WD". THE CAR HAS A TRANSMISSION BUTTON TO CHANGE FROM 2WD, AUTO, 4 HIGH AND 4 LOW. I DO NOT TOUCH THIS BUTTON, I JUST LEAVE THE CAR IN AUTO AND DRIVE. I DO NOT TOW ANYTHING, THIS IS JUST A FAMILY CAR USED FOR COMMUTING. WHEN THE "SERVICE 4WD' MESSAGE APPEARS, THE CAR IS BARELY DRIVABLE. WHEN IT IS PUT IN REVERSE, THE CAR JUST BRAKES AFTER A FEW FEET, AS IF THE PARKING BRAKE WERE ON, BUT IT OBVIOUS IS NOT ENGAGED. WHEN TURNING LEFT OR RIGHT, THE CAR BRAKES MID-TURN AND WILL ONLY COMPLETE THE TURN IF 3/4 TO FULL ACCELERATOR IS APPLIED TO CONTINUE THROUGH THE TURN. THE CAR SLIGHTLY BUCKS THROUGH THE TURN AND THE ENGINE SOUNDS DIFFERENT AND HAS LITTLE POWER GOING AROUND CORNERS AND GOING UP HILLS. THE CAR CANNOT SAFELY BE DRIVEN IN A STRAIGHT LINE FASTER THAN 40-50 MPH. I TELEPHONED ONSTAR AND DIAGNOSTICS WERE RUN DURING BOTH OCCURRENCES WITH THE SAME ERROR MESSAGE FROM ONSTAR DIAGNOSTICS: "THE BRAKING SYSTEM HAS AN ISSUE- TRANSFER CASE MODULE NOT WORKING AS EXPECTED". WHEN WILL GM ISSUE A RECALL ON THIS SAFETY ISSUE, I DO NOT FEEL SAFE LETTING MY WIFE AND CHILD IN THE CAR IF IT BRAKES BY ITSELF, LOSES POWER AND CANNOT COMPLETE TURNS. I PURCHASED THIS CAR TO HAVE A SAFE/LARGE VEHICLE FOR MY FAMILY: SERVICE 4WD APPEARS ON SCREEN IT RENDERS THE CAR UN-DRIVABLE AND THE TRANSMISSION BUTTON BECOMES INOPERABLE AND SELECTING OTHER TRANSMISSION MODES BECOMES NOT POSSIBLE. *TR

I JUST COMPLETED A CLAIM FOR MY 2015 YUKON DENALI, NHTSA ID #: 10643049 AND READ THAT ALMOST THE SAME EXACT ISSUES ARE GOING ON WITH THE 2015 CHEVY TAHOE MODELS, SEE: NHTSA ID NUMBER: 10638437, 10633519 AND 10631583. WHEN WILL GM SEE THERE IS A PATTERN AND ISSUE A RECALL FOR THIS TRANSMISSION ISSUE? IN ALL CASES THESE RENDER THE CALLS UN-DRIVABLE AND HAVING TO HAVE THEM TOWED. *TR

TL* THE CONTACT OWNS A 2015 GMC YUKON. SHORTLY AFTER THE CONTACT PURCHASED THE VEHICLE, THERE WAS AN ELECTRICAL FAILURE AND THE RADIO FAILED TO FUNCTION. THE DEALER (PENSKE BUICK GMC OF CERRITOS, 17720 CRUSADER AVE, CERRITOS, CA 90703, (877) 886-6265) REPLACED THE RADIO WITH A WARRANTY; HOWEVER, THE FAILURE CONTINUED. ALSO, THE VENT CONTROLS FAILED FOR THE AIR CONDITIONER AND HEATER. WHILE MAKING A LEFT TURN AND A U TURN, THE STEERING WHEEL SEIZED SEVERAL TIMES. THE DEALER INDICATED THAT THEY SERVICED THE VEHICLE PER NHTSA CAMPAIGN NUMBER: 18V586000 (STEERING) AND WAS AWARE THAT THE RECALL REMEDY FAILED. THE CONDITION PROGRESSED TO THE POINT THAT THE VEHICLE BEGAN TO STALL. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE MULTIPLE FAILURES. THE FAILURE MILEAGE WAS NOT AVAILABLE.

2015 GMC YUKON XL HAD BEEN IN SERVICE LESS THAN 4 MONTHS, ONLY 5000 MILES. DRIVER WAS DRIVING 65 MPH IN MODERATE TRAFFIC ON INTERSTATE 15 WHEN THE SUNROOF SPONTANEOUSLY SHATTERED INTO TINY PIECES. NO AIRBORNE ROCKS OR OTHER DEBRIS WAS PRESENT THAT COULD HAVE STRUCK THE WINDOW. ABOUT 4PM, WEATHER WAS SUNNY, TEMPERATURE MID 90'S. THE SUNROOF COVER WAS CLOSED WHICH PREVENTED MOST OF THE GLASS SHARDS FROM ENTERING THE VEHICLE, BUT DID SCATTER GLASS SHARDS ACROSS THE INTERSTATE. *TR

WHEN THE VEHICLE GOES INTO 4 CYLINDER MODE AND YOU HOLD THE SPEED STEADY OR GIVE IT A LITTLE GAS IT STARTS TO VIBRATE YOU CAN FEEL THE VIBRATION IN THE STEERING WHEEL AND ON THE FRONT CONSOLE GIVE IT ENOUGH GAS TO MAKE IT GO INTO 8 CYLINDER MODE THE VIBRATION GOES AWAY. *TR

MY NEW, 2015 GMC DENALI IS EQUIPPED WITH A BACKUP CAMERA AND THE QUALITY IS SO POOR AT NIGHT, AS TO MAKE IT NEARLY MORE DANGEROUS TO USE THAN TO IGNORE IT. I HAVE HAD 3 PRIOR GMC DENALI AUTOMOBILES. THE MOST RECENT WAS A 2011 WHICH WAS TRADED IN FOR THIS NEW ONE. THE QUALITY OF THE BACKUP CAMERA IN THE 2011 MODEL WAS EXCELLENT. MY WIFE AND I IMMEDIATELY NOTED ON THE NEW CAR THAT THE CAMERA IMAGE WAS SO BLURRY AND POOR RESOLUTION AT NIGHT, WE COULD NOT SAFELY USE THE CAMERA TO BACK OUT OF OUR GATED DRIVEWAY. IN THE DAYTIME, THE IMAGE IS BLURRY AS WELL, BUT USABLE. GMC HAS HAD THE CAR TWICE FOR SERVICE AND WE HAVE COMPLAINED TO GMC CORPORATE AND ALL WE GET IS A STATEMENT THAT THE "SYSTEM IS WORKING NORMALLY" WHICH IS DIFFICULT TO ACCEPT. THE NHTSA'S OWN STATISTICS SHOW THAT EACH YEAR APPROX. 20 PEOPLE DIE AND 15,000 ARE INJURED DUE TO BACKUP INCIDENTS. THEIR GUIDELINES STATE A CAMERA NEEDS TO DISPLAY (CLEARLY I WOULD ASSUME) A 10 X 20 FOOT ZONE BEHIND THE VEHICLE. AT NIGHT, YOU CANNOT SEE 20 FEET CLEARLY BEHIND THIS VEHICLE, EVEN IN A WELL LIGHTED STREET. I AM CONVINCED THAT THIS POOR QUALITY SYSTEM IS GOING TO CAUSE ACCIDENTS IF IT HAS NOT DONE SO ALREADY. GMC HAS AN OBLIGATION TO ADDRESS WHAT I BELIEVE IS A SUB-STANDARD QUALITY IMAGE. THEY CANNOT DEFEND THE FACT THAT THE IMAGE IS MUCH WORSE THAN OLDER MODELS OF THEIR VEHICLES. FORTUNATELY, THE NEW DENALI MODEL DOES HAVE A SENSOR SYSTEM THAT PROVIDES A VIBRATORY WARNING IF YOU ARE ABOUT TO CONTACT AN OBJECT, BUT OBVIOUSLY THE DRIVER NEEDS TO SEE CLEARLY BEHIND THEM, BEFORE THEY ARE ABOUT TO STRIKE AN OBJECT IN THEIR PATH. I AM HOPING YOUR AGENCY CAN CONTACT GMC TO HELP MOTIVATE THEM TO ADDRESS THIS ISSUE AND IMPROVE THE SAFETY OF THEIR VEHICLE(S) BEFORE THE DEFECT CONTRIBUTES TO AN UNNECESSARY INJURY OR DEATH. IN THE MEANTIME, WE DO NOT USE THE SCREEN IMAGE AT NIGHT. THANK YOU. *TR
