2016 GMC Yukon XL complaints

REAR LED TAIL LAMPS HAVE A HIGH FAILURE RATE, LEAVING THE VEHICLE IN THE DARK AT NIGHT. THIS HAS OCCURRED 2 TIME OVER THE PAST 2 YEARS. LIGHT HAS NOW BEEN OUT SINCE JAN 2019 AND GM CLAIMS THEY ARE STILL WAITING ON THE PART.

ATTEMPTED TO SLOW DOWN BY STEPPING ON BRAKES BUT THE PEDAL WAS EXTREMELY STIFF AND THERE WAS NO STOPPING ACTION. HAD TO ALMOST STAND ON THE BRAKE PEDAL WITH ALL MY FORCE TO GET THE VEHICLE TO STOP BEFORE ALMOST HITTING THE VEHICLE IN FRONT. WE HAD THE VEHICLE TOWED TO A DEALER AND THEY SAID THE BRAKE BOOSTER PUMP HAD FAILED AND NEEDED REPLACEMENT

DRIVERS' SIDE BRAKE LIGHT/TAIL LIGHT FAILURE AT 44K MILES. GMC REFUSES TO FIX UNDER WARRANTY (EVEN WITH EXTENDED WARRANTY PURCHASED) DESPITE THOUSANDS OF PEOPLE HAVING THIS ISSUE. DEALER QUOTED $1,000 TO FIX JUST THE ONE SIDE AND ADMITTED THIS IS A KNOWN ISSUE. I WAS STOPPED BY ANOTHER DRIVER AT A RED LIGHT TO INFORM ME OF THE ISSUE - HE SAID HE NEARLY HIT ME BECAUSE OF IT AND WAS SCARED.

THE PASSENGER SIDE TAILLIGHT ON THE VEHICLE WORKS INTERMITTENTLY. AS OF LATE IS HAS BEEN COMPLETELY OUT AND NOT FUNCTIONING AT ALL.

THE RIGHT REAR TAIL LIGHT BRAKE LIGHTS HAVE GONE COMPLETELY OUT. THESE ARE ONE SOLID HOUSING AND HAVE TO BE REPLACED TO SIMPLY FIX THE BRAKE LIGHT. REVERSE AND TURN SIGNAL LIGHTS ARE OK. THE HOUSINGS COST 600-700 DOLLARS EACH TO REPLACE WHICH IS A LUDICROUS AMOUNT TO HAVE TO SPEND. IN ORDER TO BE WITHIN REGULATIONS FOR INSPECTION, THESE HAVE TO BE WORKING. WE FEEL THERE SHOULD BE A RECALL AS THERE ARE LOTS OF COMPLAINTS ONLINE ABOUT THESE HOUSINGS.

A FEW MONTHS AGO THE DRIVER SIDE TAILLIGHT STOPPED WORKING (OR WOULD ONLY WORK INTERMITTENTLY). TOOK TO DEALER AND THEY SAID IT WAS $850 TO REPAIR. FILED COMPLAINT WITH GMC AND AS I WAS WORKING THROUGH THAT WITH THEM THE PASSENGER SIDE TAILLIGHT STOPPED WORKING AS WELL. NOW I HAVE A VEHICLE THAT IS NOT EVEN 3 YEARS OLD WITHOUT WORKING TAILLIGHTS. THIS IS TOTALLY RIDICULOUS. A $65,000 'PROFESSIONAL GRADE' VEHICLE SHOULD NOT BE HAVING THIS ISSUE AT 55,000 MILES. GMC NEEDS TO WAKE UP AND RECALL THESE. WILL IT TAKE A FATAL ACCIDENT TO SPUR A RECALL??

DRIVER SIDE BRAKE LIGHT OUT . ITS A KNOWN ISSUE WITH THE LIGHTS AND GMC REFUSES TO ACKNOWLEDGE ITS AN ISSUE...

THE DRIVERS SIDE BRAKE/RAIL LIGHT STOPPED WORKING AND VEHICLE ONLY HAS 27,800 MILES ON IT. HAVE SEEN AND HEARD OF MANY OTHERS WITH THE SAME PROBLEM. LED LIGHTS SHOULD LAST LONGER THEN INCANDESCENT LIGHTS.

REAR RIGHT BRAKE LIGHT WENT OUT DUE TO KNOWN DEFECT. METAL PIECE BROKE THAT ALLOWS A CONNECTION BETWEEN THE LED LIGHTS. GMC SHOULD RECALL THESE LIGHTS SINCE THERE ARE SO MANY PEOPLE HAVING SAFETY ISSUES WITH THEM.

THE REAR BRAKE LIGHTS ARE NOT FUNCTIONING CONSISTENTLY. THE TURN LIGHT AND REVERSE LIGHT WORK BUT NOT THE BREAK LIGHTS. THEY ARE THEIR OWN ASSEMBLY AND HAVE TO BE REPLACED AT A COST OF $650/EACH AT THE DEALERSHIP. ONLINE I FOUND HUNDREDS OF OTHERS THAT HAD THE SAME ISSUE.

MY CAR IS BARELY 3 YEARS OLD AND HAS ONLY 24,000 MILES ON IT BECAUSE I WORK FROM HOME. I SPECIFICALLY LEASE CARS SO I DON'T HAVE TO DEAL WITH ISSUES. THIS CARS REAR PASSENGER BRAKE LIGHT NO LONGER WORKS! THE SERVICE MANAGER AT THE GMC DEALERSHIP SAYS THEY HAVE TO REPLACE A GREAT DEAL OF THESE IN CARS NOT VERY OLD LIKE MINE. THIS IS DEFINITELY A SAFETY ISSUE FOR BRAKE LIGHTS TO BE GOING OUT ON A 3 YEAR OLD CAR! IT HAS BEEN OUT FOR MONTHS AND I WAS JUST PROCRASTINATING BECAUSE YOU MUST GO TO A DEALERSHIP SHOP TO GET IT REPLACED. YOU CANNOT GET IT AT A PART STORE YOURSELF SO MY CAR PROBABLY ONLY HAD 20,000-21,000 MILES ON IT WHEN THIS STARTED.

REAR LED BRAKE LIGHTS NO LONGER LIGHT UP.

BRAKES DO NOT WORK AT LOW SPEEDS. GMC TOLD ME THAT THE PARTS HAD BEEN BOUGHT BACK BY GM AND THERE WAS NO WAY TO FIX IT 8 MONTHS AGO AND NOW THEY STATE THERE IS A SPECIAL WARRANTY ADDED EXCEPT MY MILEAGE IS OVER THE WARRANTY! BRAKES EITHER ARE HARD AS A BRICK TO PUSH OR/AND DON'T WORK AT ALL. I WAS TOLD TO REV THE ENGINE WHEN GOING SLOW OR BACKING UP IN ORDER TO MAKE THE BRAKES FUNCTION PROPERLY. THAT WAS THE ADVICE FOR A MOTHER OF 4 CHILDREN. AC IS ALSO BLOWING HOT AIR.

FAULTY BREAK LIGHTS. THE LED CIRCUIT IS FAULTY AND CRACKS WHICH REQUIRES THE ENTIRE LIGHT ASSEMBLY TO BE REPLACED.

I HAVE BEEN TOLD BY MULTIPLE PEOPLE THAT ONE OR BOTH OF MY BRAKE LIGHTS HAS NOT BEEN WORKING. I HAVE TESTED THEM MYSELF AND I TOO GET MIXED RESULTS. SOMETIMES ONE WORKS AND OTHER TIMES NEITHER. BEING THAT I DRIVE 30 MINUTES TO AND FROM WORK EVERYDAY THIS IS A MAJOR CONCERN.

VEHICLE HAS 52,000 MILES ON IT AND DRIVER SIDE TAIL LIGHT STOPPED WORKING. IT IS AN LED AND SHOULD LAST FOR MANY YEARS. HAS NOT BEEN IN AN ACCIDENT. THIS IS FAULTY MANUFACTURING. CONSUMER PROTECTION NEEDED.

REAR PASSENGER LIGHT IS NOT WORKING. THE BOARD IS CHEAPLY MADE AND DEALER WANTS ME TO BUY A NEW LIGHT FIXTURE FOR $800.

MY DRIVERS SIDE TAIL LIGHT IS OUT! DEALER CHARGES $700 TO REPAIR!

MY 2016 GMC YUKON XL RECENTLY BEGAN HAVING A HARD BRAKE PEDAL WHEN REVERSING OUT OF PARKING SPOTS, OR WHEN ROLLING DOWNHILL. A COUPLE OF TIMES, WHEN ROLLING FORWARD DOWNHILL IT MALFUNCTIONED CAUSING ME TO RUN INTO A DITCH. . THE HARD BRAKE PEDAL HAD CAUSED ME TO NOT BE ABLE TO STOP THE VEHICLE SEVERAL TIMES. IT WOULD ROLL BACKWARDS (OR FORWARDS) UNTIL I SHIFTED IT IN TO GEAR OR GAVE IT GAS. A FEW TIMES I ALMOST HIT VEHICLES AND PEDESTRIANS IN MY SON'S SCHOOL CARPOOL LANE. THERE IS NO WARNING. NO CHECK ENGINE LIGHT. JUST THE HORRIBLE ROCK HARD BRAKE PEDAL WHICH TURNS OUT TO BE A FAULTY VACUUM PUMP PER NAPA JIMMY VASSER CHEVROLET, THAT HAS NOW COST ME $711.00 BECAUSE IT IS NOT COVERED UNDER WARRANTY. MY CAR HAS 54,000 MILES ON IT. THIS IS UNACCEPTABLE.

REAR BRAKE LIGHT WORKS INTERMITTENTLY.

REAR TAIL LIGHT / BRAKE LIGHT QUIT WORKING WHILE STILL UNDER WARRANTY. WE TOOK IT TO THE DEALER AND WAS DENIED COVERED. THE UNIT IS A COMPLETE LED ASSEMBLY AND CANNOT BE REPAIRED. THE PRICE QUOTED WAS $700 FOR THE ASSEMBLY. A QUICK INTERNET SEARCH SHOWS THAT THOUSANDS OF PEOPLE HAVE EXPERIENCED THE SAME ISSUE AND GM WILL NOT ACKNOWLEDGE IT AS A PROBLEM AND WILL NOT COVER UNDER WARRANTY. THIS IS MOST DEFINITELY A DANGEROUS SITUATION FOR OWNERS WHO SUDDENLY HAVE NO TAIL OR BRAKE LIGHTS ON THEIR NEW/NEWER VEHICLES.

THE BACK MASSAGER TAIL LIGHT HAS STOPPED WORKING. AFTER MUCH RESEARCH THIS SEEMS TO BE A PROBLEM WITH THE VEHICLE. TO REPLACE THE LIGHT (ONE LIGHT), I WAS QUOTED $750.

TAIL LIGHT ISSUES. REPLACED DRIVER SIDE LIGHT APPROXIMATELY LESS THEN 6 MONTHS AGO AND PASSENGER TAIL LIGHT IS OUT. SAME ISSUES AS DRIVER SIDE LIGHT.

BRAKES GET VERY HARD TO PUSH AND DO NOT WORK WELL WHEN GOING SLOW SPEEDS OR BACKING UP. UNABLE TO EVEN FIX AS I HAVE BEEN TOLD THE PART IS ON NATIONAL BACK ORDER! SO I'M STUCK TRYING NOT TO CRASH WITH FAULTY VACUUM BRAKE PART! LEFT REAR SEAT MOTOR WORKS, BUT SMALL PLASTIC PART BROKE SO SEAT WORN MOVE AND IS STUCK IN ONE POSITION.

THE VEHICLE HAS EXPERIENCED AT SLOW SPEED OR BACKING A SOLID/STUCK BRAKE PEDAL THAT WOULDN'T MOVE. THE PEDAL WAS BASICALLY STUCK, NOT MOVING AT ALL. THIS OCCURRED COMING TO A STOP AT LIKE AN INTERSECTION OR AS STATED BACKING OUT OF A PARKING SPOT. IT FELT AS IF THE TRUCK WOULDN'T STOP AND NO MATTER HOW HARD THE PEDAL WAS PUSHED IT WOULDN'T MOVE FOR A FEW SECONDS.

BEGINNING AROUND 70K MILES, MY WIFE COMPLAINED OF BRAKES NOT WORKING AT LOW SPEED IN PARKING LOTS, ESPECIALLY IN REVERSE, WITH VERY HARD PEDAL, OCCASIONAL OCCURRING. WHILE I WAS DRIVING, OCCURRED MULTIPLE TIMES AT GAS STATION AT VERY LOW SPEED DURING STOP OVER ON A LONG ROAD TRIP AT 80K MILES. UPON TAKING TO GM DEALERSHIP FOR ANOTHER ISSUE, GM SERVICE TECHNICIAN VERIFIED THE CONCERN. VACUUM PUMP REPLACED ON 12/14/18. FEW MILES SINCE BUT TEST DRIVING HAS NOT HAD ANOTHER OCCURRENCE. VEHICLE FAILURE CONFIRMATION AND REPAIR DONE AT JOE BOWMAN CHEVROLET IN HARRISONBURG, VA.

LOW SPEED BRAKE FAILURE: AT LOW SPEEDS THE BRAKE PEDAL BECAME FIRM AND THE VEHICLE DID NOT STOP IN AN APPROPRIATE TIME. THIS LED TO TWO NEAR ACCIDENTS. BOTH TIMES THE VEHICLE WAS IN A LINE OF CARS THAT WAS STOP AND GO PICKING UP CHILDREN AT AFTER SCHOOL. SERIOUS CONCERN THAT THE VEHICLE WILL NOT STOP AND INJURE CHILDREN TRYING TO LOAD OR UNLOAD. THE PROBLEM APPEARS TO OCCUR ONLY AT LOW SPEEDS ONLY.

DRIVING AT LOW SPEEDS (5 MPH OR BELOW) THE BRAKES FAILED TO ENGAGE. THE BRAKE PEDAL WAS STIFF AND OFFERED LITTLE PRESS. PRESSING THE PEDAL EXTREMELY HARD BROUGHT THE VEHICLE TO A STOP. THIS HAPPENED MULTIPLE TIMES IN A SINGLE DAY, ALMOST CAUSING AN ACCIDENT IN TRAFFIC AND DID CAUSE ME TO BUMP INTO OUR GARAGE WALL. WHEN A I TOOK THE VEHICLE IN TO BE SERVICED, THE VACUUM PUMP HAD TO BE REPLACED. OUR VEHICLE AS 39,800 MILES. THIS APPEARS TO BE A KNOWN DEFECT: TECHNICAL BULLETIN PIT5361B EXISTS A CLASS ACTION LAWSUIT HAS RECENTLY BEEN FILED (HTTPS://WWW.CARCOMPLAINTS.COM/NEWS/2018/GM-BRAKE-VACUUM-PUMP-FAILURES-LAWSUIT.SHTML) A QUICK INTERNET SEARCH REVEALS MULTIPLE SIMILAR ISSUES. COST TO REPAIR IS OVER $900 AT GMC DEALER.

VERY STRONG SMELL OF A GAS LEAK ON THE DRIVER SIDE OF THE VEHICLE. NO MATTER THE FUEL LEVEL, RUNNING OR STOPPED FOR HOURS.

REAR PASSENGER BRAKE LIGHT STOP WORKING, VEHICLE IS ONLY 2 YEARS OLD. WE SHOULD NOT BE HAVING THIS ISSUE SO SOON OR AT ALL, SINCE LED LIGHTS NORMALLY DONT STOP WORKING. I ALSO LOOKED INTO FIXING IT AND ITS GONNA COST $700 DOLLARS. THIS IS RIDICULOUS!

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. WHILE THE CONTACT'S WIFE WAS DRIVING 65 MPH, WATER LEAKED FROM THE HEADLINER CONSOLE. THE VEHICLE WAS NOT TAKEN TO A DEALER TO BE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 62,000.

ON 9/25/18 WHILE APPLYING BRAKES THE BRAKE PEDAL BECAME EXTREMELY HARD TO PRESS AND VERY HARD TO STOP THE VEHICLE. THANK GOD IT WAS IN MY DRIVEWAY THIS OCCURRED. MY SIGNIFICANT OTHER CAME HOME FROM WORK ON 9/27/18 AND CHANGED PADS, LUBED CALIPER SLIDERS, AND VERIFIED PROPER CALIPER OPERATION. SPENT 9/26/18 TALKING WITH THE DEALER AND CHECKING RECALLS. ALL THESE REPAIRS WERE SUGGESTED BY THE LOCAL DEALER, BY THEM OF COURSE. UPON TEST DRIVE AFTER NEW PADS WERE INSTALLED, THE SAME ISSUE HAPPENED. DRIVING FORWARD THE BRAKES OPERATE AS THEY SHOULD OR AT LEAST FEEL NORMAL.

PROGRESSIVE INTERMITTENT BRAKE LIGHT FUNCTIONALITY THAT EVENTUALLY CULMINATED WITH COMPLETE INOPERABILITY; ONLY THE RIGHT/LEFT BRAKE LIGHT ASSEMBLIES ARE AFFECTED; REVERSE LAMPS OPERATE; UPPER CENTER BRAKE LIGHT FUNCTIONS NORMALLY; THIS IS A KNOWN PROBLEM WITH GMC BRAKE LIGHT ASSEMBLIES PER MULTIPLE FORUMS

DRIVERSIDE TAIL LIGHT INTERMITTENTLY STOPS WORKING. CAR MILAGE IS IN THE 40,000'S. DIAGNOSTIC TEST AT DEALERSHIP WHERE PURCHASED CONFIRMS " DRIVER REAR TAIL LIGHT SHORTED OUT INTERNALLY. RECOMMEND REPLACING DRIVER TAIL LIGHT. RECOMMEND TAIL LIGHT ASSEMBLY $899" . MY SISTER HAS A YUKON XL DENALI 2016 AND HAS THE SIMILAR ISSUE BUT BOTH OF HER TAIL LIGHTS INTERMITTENTLY STOP WORKING POSING A HUGE SAFETY CONCERN. DRIVING IN MY AREA I SEE MANY NEWER YUKON XL WITH THE DRIVER SIDE TAIL LIGHT OUT. LIGHTING IS NOT COVERED UNDER EXTENDED WARRANTY AND COST TO FIX IS EXTREMELY EXPENSIVE, WHICH COULD MAKE THE AVERAGE DRIVER PUT OFF THE LARGE EXPENSE. THE TAIL LIGHT INTERMITTANTLY STOPS WORKING WHILE THE CAR IS ON, DOES NOT MAKE A DIFFERENCE IF THE CAR IS STATIONARY OR IN MOTION. SERVICE REP AT DEALERSHIP STATED THIS PROBLEM IS "COMMON".

BOTH TAIL LIGHTS AND BRAKE LIGHTS STOPPED FUNCTIONING WITHIN A WEEK OF EACH OTHER. NO BULB TO REPLACE AS THEY ARE LEDS AND ENTIRE HOUSING HAS TO BE REPLACED.

MODEL YUKON XL 2016, LESS THAN 50K MILES, BRAKE LIGHTS HAVE FAILED COMPLETELY. NO REAR BRAKING LIGHTS. ENTIRE ASSEMBLY HAS TO BE REPLACED. FIRST NOTICED IN JULY, HAVE ONLY HAD VEHICLE FOR 14 MONTHS.

THE PASSENGER TAIL LIGHT AND BRAKE LIGHT WORK INTERMITTENTLY.

GMC BRAKE LIGHT FAILURE - I OWN A 2016 GMC YUKON XL AND AFTER ABOUT 45,000 MILES THE BRAKE LIGHTS HAVE STARTED INTERMITTENTLY NOT WORKING. AFTER HAVING A GMC TECHNICIAN TELL ME THAT ITS A KNOWN ISSUE AND SEEING HUNDREDS OF OTHERS POSTS ONLINE, IT IS EVIDENT THAT THIS IS A VERY WIDESPREAD PROBLEM. I WAS NEARLY INVOLVED IN A REAR END CRASH ON THE FREEWAY BECAUSE THE DRIVER TOLD ME I DID NOT HAVE ANY BRAKE LIGHTS. THIS IS A SERIOUS SAFETY ISSUE AND GMC NEEDS TO CORRECT IT. THEY WANT ME TO PURCHASE 2 REPLACEMENT LIGHT UNITS AT 750.00 EACH.

MY DRIVER SIDE LED TAILLIGHT WENT OUT. YOU CAN NOT JUST CHANGE A BULB OR THE LED STRIP. IT REQUIRES THE WHOLE ASSEMBLY BE REPLACED. MY VEHICLE IS 2 YEARS OLD. IT SHOULD NOT GONE OUT AFTER 2 YEARS, LET ALONE IT BEING AN LED WHICH IS SUPPPSE TO LAST MUCH MUCH LONGER THAN THAT. I WAS TOLD WHILE DRIVING, IT WOULD GO ON THEM OFF. IT WAS DUSK AND I WAS DRIVING ON A SURFACE STREET WITH LOTS OF TRAFFIC. THAT IS NOT SAFE. I HAVE MULTIPLE FRIENDS AND FAMILY MEMBERS WHO HAVE ALSO HAD THIS PROBLEM. THE INTERNET THREADS HAVE MANY MORE COMPLAINTS AS WELL.

BOTH BREAK LIGHTS WENT OUT, WEATHER HAS BEEN HOT IN THE HIGH 90S WHICH GMC DEALER EXPRESSED COMMON CONCERN AMONG OWNERS DURING SUMMER. VEHICLE IS USED 15MILES/DAY ON AVERAGE.

WHEN STARTING AND STOPPING (DEPRESSING THE BRAKE PEDAL MULTIPLE TIMES) SUCH AS AT A LEFT TURN (WAITING FOR TRAFFIC) OR A DRIVE-THRU WINDOW, THE BRAKES STOP WORKING AND THE CAR ROLLS FORWARD EVEN WHEN THE BRAKE IS DEPRESSED. IF YOU PRESS REALLY HARD IT WILL USUALLY STOP- BUT IT DEFINITELY ROLLS FORWARD WHEN YOU ARE TRYING TO STOP. THE DEALERSHIP SAYS THAT A VACUUM PUMP IS FAULTY BUT THIS COULD RESULT IN AN ACCIDENT AS I ALMOST ROLLED INTO ONCOMING TRAFFIC WHILE WAITING IN LINE TO TURN LEFT AT A "LEFT TURN YIELD ON GREEN LIGHT".

AIR CONDITIONING SYSTEM CONSTANTLY BLOWS OUT HOT AIR. AIR CONDITION WAS RECHARGED AND STILL HAS NEGATIVE RESULTS.

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. ON SEVERAL OCCASIONS, WHEN THE BRAKE PEDAL WAS DEPRESSED AT LOW SPEEDS, THE BRAKES FAILED TO SLOW DOWN THE VEHICLE. THE CONTACT STATED THAT THE FAILURE WAS INTERMITTENT. THE VEHICLE WAS TAKEN TO SOUTHERN PINES CHEVROLET BUICK GMC (10722 US-15, SOUTHERN PINES, NC 28387, (910) 692-2002) WHERE IT WAS DIAGNOSED THAT THE BRAKE LINES AND VACUUM PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 60,000.

HIGH FREQUENCY ANTENNA LEAKING WATER. THIS IS PREVENTING THE VEHICLE'S ONSTAR SYSTEM FROM ACCURATELY DETERMINING THE VEHICLE'S LOCATION; IT HAS DISABLED VEHICLE'S COMPASS, NAVIGATION, AND XM RADIO SYSTEMS; THE RED ONSTAR LED INDICATOR HAS TURNED ON ; AND WATER IS LEAKING INTO THE INTERIOR PASSENGER COMPARTMENT. A RECALL WAS ISSUED FOR THE 2015 YUKON XL FOR THIS SAME EXACT PROBLEM. HOWEVER, I AM HAVING THE SAME EXACT PROBLEM WITH MY 2016 MODEL. I HAVE ATTACHED THE RECALL ISSUED FOR THE 2015 MODELS.

TAKATA RECALL OR SENSOR FAILURE. WHILE DRIVING 45MPH, AND JUST SLAMMED THE BRAKES REAR ENDING THE STOPPED CAR IN FRONT OF ME. THE AIRBAG FAILED TO DEPLOY. I HAD EXTENSIVE DAMAGE TO MY FRONT END AND THE CAR I HIT WAS TOTALED. THAT AIR BAG SHOULD OF DEPLOYED.

BOUGHT SUV 6/25/2016 THE SAME WEEKEND THE ENGINE TURNS OFF AFTER A LEFT OR RIGHT TURN :IT HAS HAPPENED 3 TIMES SO FAR. 4 WEEK OLD 2016 YUKON DENALI XL, HAS STALLED 3 TIMES IN LAST 4 WEEKS, ENGINE CUTS OFF AFTER A LEFT OR A RIGHT TURN ONLY AFTER A SHORT DRIVE OUT OF HOME. THE SUV HAS TO BE RESTARTED! COULD HAVE EASILY HAD AN ACCIDENT OR WORSE. I TOOK IT TO THE WESTPOINT GMC DEALER, 3 TIMES. 1ST TWO TIMES, ALL OF SERVICE DEPTARTMENT COULD NOT DIAGNOSE THE PROBLEM. TODAY, AFTER A STALL, I CALLED ONSTAR, WHO RAN A DIAGNOSTICS TEST,BUT ONSTAR FOUND NOTHING OF VALUE , I LEFT IT AT DEALERSHIP AND CONTACTED DISTRICT MGR. MATT TILLSON . I WAS TOLD THAT THEY WOULD ESCALATE THE ISSUE. I DID TELL DEALER THAT GMC AND DEALERSHIP WOULD BE AT FAULT IF VEHICLE IS INVOLVED IN AN ACCIDENT AND STALLS NOR STOPS WHILE I AM DRIVING. I DID NOT WANT THE VEHICLE BACK WITHOUT THE PROBLEM HAVING BEEN FIXED. ITS DAY 6 TODAY. I NEED TO MAKE IT ABSOLUTELY CLEAR, I WILL NOT TAKE THE VEHICLE BACK UNTILL THE PROBLEM HAS BEEN DIAGNOSED, AND FIXED. I DO NOT WANT ME OR MY FAMILY OR GM SERVICE EMPLOYEE INJURED, OR WORSE, OR TO BE INVOLVED WITH A POSSIBLE ACCIDENT IN MY GMC YUKON DENALI XL. A FIELD SERVICE ENGINEER SHOULD HAVE BEEN ON THIS CASE ALREADY ! WILL IT TAKE AN ACCIDENT, OR INJURY BEFORE SOMEONE GETS ASSIGNED?

EXCESSIVE VIBRATION/BUFFETING DRONE ISSUES (AT ALL SPEEDS OF THE VEHICLE) HAVE CAUSED SEVERE HEALTH ISSUES AND SAFETY HAZARDS FROM DRIVING THE VEHICLE. WITHIN THE FIRST 8,000 MILES OF OWNING THE CAR, THE CAR HAS NOW BEEN IN SERVICE FOR 40 DAYS AS GM TRIES AND REMEDY THE PROBLEM, BUT THERE DOES NOT APPEAR TO BE A FIX. SO FAR, DIAGNOSTIC TESTS INDICATED THAT THERE WAS A FAULTY BEARING IN THE REAR DIFFERENTIAL THAT LED TO SIGNIFICANT ABNORMAL WEAR THROUGHOUT THE DIFFERENTIAL AND THE DIFFERENTIAL NEEDED TO BE REBUILT. WHEN REBUILDING, THEY DISCOVERED THAT THE DISASSEMBLED DIFFERENTIAL HAD HEAVILY SCORED BEARINGS AND METAL SHAVING THROUGHOUT EVERY BEARING. RING GEAR AND PINION HAD IRREGULAR WEAR CAUSING A DRONE IN THE VEHICLE. RACE SURFACES WEAR GROUND AND SCARRED BAD.THE REBUILT DIFFERENTIAL DID NOT FIX THE ISSUE AND NOW AFTER HAVING FOUR NEW TIRES AND ROAD BALANCING, THE PROBLEMS DIDN'T DIMINISH BUT WERE EXACERBATED. AFTER REBUILDING THE DIFFERENTIAL AGAIN, GM HAS NOW DETERMINED THAT THE REAR AXLE MAY NEED TO BE REPLACED AND ENGINEERS ARE LOOKING INTO THE PROBLEM FURTHER. THE STEERING WHEEL SHAKES AND THE CAR HAS A TERRIBLE VIBRATION THAT WORSENS EVERY TIME GM ATTEMPTS TO SERVICE THE VEHICLE. THIS SEEMS TO BE A WELL-DOCUMENTED PROBLEM THAT GM HAS AVOIDED FIXING. WE ADVISE OTHER CONSUMERS TO BE AWARE OF THE SERIOUS SAFETY PROBLEMS RELATED TO THE POOR MANUFACTURING OF THE VEHICLE AND INABILITY OF GM TO REMEDY THE PROBLEM.

IN MY YUKON WHILE IDLEL THE CAR START SHAKING SO BAD, IT HAS A VIBRATION YOU CAN SEE THE NEEDLE GOING UP AND DOWN, TOOK IT SEVERAL TIME TO THE DEALER AND THEY SAID THEY KNOW IS A PROBLEM WITH THE CAR BUT GENERAL MOTOR COMPANY HAS NOT ISSUE ANY REPAIR FOR THAT AT THIS MOMENT, I CONTACT GENERAL MOTOR COMPANY THEY SAID THE CAR IS OPERATING NORMAL BASE ON THE REPORT PROVIDED BY THE DEALERS, FOR ME IS NOT NORMAL HAVING A BRAND NEW CAR SHAKING AND VIBRATING LIKE IF WILL TURN OF, LOOKS LIKE IF MISFIRED ON THE ENGINE,

TL* THE CONTACT OWNS A 2016 GMC YUKON XL. WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE VIOLENTLY VIBRATED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE TECHNICIAN REPLACED THE WHEELS, BUT THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER. THE CONTACT WAS INFORMED THAT THE VEHICLE WAS OPERATING AS DESIGNED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 2,000.

VIBRATION AT SPEEDS OVER 72 MPH BECOMES WORSE WHILE GOING UP GRADE WHILE ACCELERATING ..HAS BEEN IN SHOP MANY TIMES NEW TIRES, BALANCED MULTIPLE TIMES ,ALONG WITH SUSPENSION PARTS AND DRIVE TRAIN PARTS. STILL NOT FIXED SUV HAS 22 INCH RIMS.
