What 450 owners told NHTSA about the 2016 GMC Yukon Xl 1500

LED TAILLIGHT ON 2016 YUKON DENALI IS NOT WORKING. THIS IS THE SECOND TIME THIS HAS HAPPENED. THIS IS A COMMON ISSUE AND GM WILL NOT COVER A KNOWN ISSUE.

NHTSA ODI 11204819

THE REAR TAIL/BRAKE LIGHTS ON THE GMC YUKON SERIES HAVE A DEFECT THAT KEEP CAUSING THE RUNNING LIGHTS AND BRAKE LIGHTS TO WORK INTERMITTENTLY. I HAD AN ENTIRE NEW LIGHT INSTALLED AND THE SAME ISSUE OCCURRED WITHIN A FEW THOUSAND MILES. GMC IS AWARE OF THIS PROBLEM AND HAS YET TO ISSUE A RECALL FOR THESE DEFECTIVE LIGHTS. OBVIOUSLY THIS IS AN IMPORTANT SAFETY FEATURE OF THE VEHICLE IN ORDER TO ALERT OTHER DRIVERS OF MERE PRESENCE, BRAKING, AND TURNING ACTIONS.

THE AIR CONDITIONING CONDENSERS AND ASSOCIATED PARTS ARE FAILING ON THE 2016 GMC YUKON. GMC HAS YET TO ISSUE ANY RECALL EVEN THOUGH THESE AC UNITS ARE CONSTANTLY BREAKING ON THESE VEHICLES.

REAR LED BRAKE LIGHTS NO LONGER LIGHT UP.

STARTED THE VEHICLE AFTER IT HAD BEEN SITTING FOR ABOUT 1 HOUR AND THE GAUGES DID THEIR REGULAR CHECK SWEEP FROM LEFT-TO-RIGHT, THEN THE FOLLOWING WARNINGS APPEARED ON THE DRIVER INFORMATION DISPLAY SCREEN: 1) SERVICE AIR BAG; 2) SERVICE TRAILER BRAKE, AND; 3) SERVICE FRONT CAMERA. AFTERWARDS, THERE WERE NO GAUGES EXCEPT THE VOLTMETER (TACHOMETER, FUEL, TEMPERATURE, OIL PRESSURE AND SPEEDOMETER WERE ALL AT RESTING POSITIONS). THE DRIVER INFORMATION SCREEN WOULD NOT SHOW THE GEAR SELECTOR, THE MILEAGE OR THE SPEED AND THE WARNING LIGHTS FOR THE AIRBAG, EMERGENCY BRAKE, TRACTION CONTROL AND TPMS STAYED ON. I DROVE THE VEHICLE A SHORT DISTANCE AND SHUT IT OFF, RESTARTED, AND IT DID NOT MAKE ANY DIFFERENCE. THERE WAS NO OPTION TO TAKE THE VEHICLE TO A DEALERSHIP FOR SERVICE IMMEDIATELY, BECAUSE WE HAD A TRAIN TO CATCH, SO WE HAD TO DRIVE IT ABOUT 20 MILES WITH NO SPEEDOMETER, BUT WE CALLED OUR GMC DEALER AND MADE A SERVICE APPOINTMENT FOR APRIL 22, 2019 ONCE WE PARKED AT THE TRAIN STATION. THE VEHICLE WAS PARKED UNTIL APRIL 21, 2019, AND, WHEN STARTED AT THAT TIME, THE INSTRUMENT PANEL AND DRIVER INFORMATION SCREEN WORKED CORRECTLY. ON APRIL 22, 2019, OUR GMC DEALER (WOODBRIDGE BUICK-GMC) PERFORMED A DIAGNOSTICS AND DISCOVERED A B3980 (NO ENVIRONMENT IDENTIFIER RECEIVED) IN THE HISTORY. ACCORDING TO THE SERVICE ADVISER I SPOKE TO, THIS CODE WILL INVOLVE THE RELAYS FOR THE TRAILER BRAKING AND THE INSTRUMENT PANEL. ALSO; THEY TOLD ME THAT THE BATTERY CABLE WAS LOOSE, SO THEY TIGHTENED THAT AS WELL. OUR EXTENDED WARRANTY DID NOT COVER THIS AND WE HAD TO PAY FOR THE DIAGNOSTICS DUE TO OUR MANUFACTURE WARRANTY EXPIRING 2 MONTHS BEFOREHAND. AS OF NOW, THIS PROBLEM HAS NOT HAPPENED AGAIN, BUT IT IS WORTH REPORTING DUE TO POSSIBLY BEING A SAFETY ISSUE.

THE LED TAIL LIGHTS GO OFF AND ON AND THE ONLY WAY TO REPAIR IS TO REPLACE THE WHOLE UNIT

NHTSA ODI 11204051

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.

PASSENGER SIDE LED BRAKE LIGHT FAILED AT 60000 MILES. $800 DEALER REPAIR QUOTE TO REPLACE. NO MANUFACTURE SUPPORT.

NHTSA ODI 11202721

PASSENGER SIDE BRAKE LIGHT NOT WORKING. YUKON HAS UNDER 40,000 MILES AND IS METICULOUSLY CARED FOR. I HAVE READ MANY OTHER COMPLAINTS ONLINE AND THIS SEEMS TO BE A QUALITY ISSUE. THERE IS NO EASY FIX AND A COMPLETE REPLACEMENT IS REQUIRED. THIS IS A SAFETY ISSUE GIVEN IT IS A BRAKE LIGHT. BRAKE LIGHTS SHOULD NOT MALFUNCTION IN THIS MANNER. A RECALL IS CERTAINLY IN ORDER AS FAILURE TO SIGNAL BRAKING CAN BE A RISK FOR MYSELF AS THE DRIVER AND OTHERS.

NHTSA ODI 11202643

RIGHT REAR BRAKE LIGHT ASSEMBLY FAILED. IT IS A SEALED ASSEMBLY AND CANNOT BE REPAIRED WITHOUT BREAKING THE SEALED/SONIC WELDED ASSEMBLY. REPLACEMENT ASSEMBLY IS $700+ DOLLARS.

NHTSA ODI 11202553

THE ANTENNA ON THE YUKON GETS WATER IN IT WHEN IT RAINS. IT HAS MESSED UP MY GPS SYSTEM AND MY ON STAR SYSTEM IS NOT WORKING. IT HAS LEAKED INTO THE SUV. THIS HAPPENS EVERY TIME IT RAINS.

NHTSA ODI 11197151

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

NHTSA ODI 11195361

VEHICLE IN MOTION AND BRAKES WOULD NOT WORK UNLESS YOU PUT ALL YOUR BODY WEIGHT ON THE BRAKES, AND THEN JUST BARELY. HAPPENED MULTIPLE TIMES ON AND OFF BOTH AT HIGH RATE OF SPEED ON HIGHWAY AND ON CITY STREETS. TOOK INTO GMC DEALERSHIP AND THEY REPLACED THE VACUUM PUMP FOR THE BRAKES -- PROBLEM SOLVED AFTER SPENDING $800. WE ARE LUCKY THIS IS A MAJOR SAFETY ISSUE THAT COULD HAVE CAUSED A SERIOUS ACCIDENT. I UNDERSTAND THIS EXACT PROBLEM IS A KNOWN PROBLEM CURRENTLY BEING INVESTIGATED. PLEASE FINISH YOUR INVESTIGATION QUICKLY AND ISSUE A RECALL -- SOMEBODY IS GOING TO GET KILLED IF THIS IS NOT FIXED. I LOOK FORWARD TO BEING REIMBURSED FROM GMC WHEN THE RECALL IS FINALLY ISSUED.

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.

MY WIFE'S 2016 GMC PASSENGER TAIL LIGHT FLICKERING WORKING WHEN IT WANTS. TRUCK HAS 50K NEVER BEEN IN ACCIDENT AND WE ARE THE ORIGINAL OWNERS.

NHTSA ODI 11193468

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.

NHTSA ODI 11193257

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

NHTSA ODI 11191242

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

NHTSA ODI 11190053

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.

NHTSA ODI 11183051

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.

NHTSA ODI 11182272

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.

NHTSA ODI 11182211

VACUUM PUMP WENT OUT ON MY VEHICLE RESULTING IN ALMOST BEING HIT BY A SEMI TRAVELING 65MPH. I HAD TO CALL A WRECKER TO PICK UP MY VEHICLE AND HAVE IT TOWED TO THE DEALERSHIP AS IT WAS NO LONGER SAFE TO DRIVE. I PAID OUT OF POCKET FOR THE WRECKER AND THE REPAIR BECAUSE THE VACUUM PUMP WAS NO LONGER COVERED UNDER WARRANTY AT 38,633 MILES. I WAS LEAVING A DRIVEWAY AT A SLOW SPEED TO TURN ONTO A FARM TO MARKET ROAD AND MY BRAKES WOULD NOT WORK.

TL* THE CONTACT OWNS A 2016 GMC YUKON. WHILE THE VEHICLE WAS ACCELERATING FROM A STOP, THE TRANSMISSION SHUDDERED AND FAILED TO RESPOND APPROPRIATELY. THE RPM GAUGE WAS ERRATIC AND FLASHED. THE VEHICLE WAS TOWED TO MARVIN K. BROWN AUTO CENTER (1441 CAMINO DEL RIO SOUTH, AUTO CIR, SAN DIEGO, CA 92108) WHERE IT WAS DETERMINED THAT A POWER TRAIN WARRANTY PROVISION WAS NOT AN AVAILABLE OPTION AND THE MANUFACTURER HAD NOT ISSUED A POWER TRAIN RECALL. THE DEALER DIAGNOSED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE REMAINED AT THE DEALER AND HAD NOT BEEN REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 130,268.

THIRD TIME THIS HAPPENED, FIRST TWO TIMES MY HUSBAND WAS DRIVING(HE CALLED THE DEALERSHIP AND THEY SAID THEY HAD NOT HEARD OF ANY PROBLEMS) AND WHEN IT HAPPENED TO ME IT WAS SCARY. I HAD MY KIDS IN THE CAR, NO INJURIES AND NO ONE WAS HURT, THANK GOD. I WAS GOING THROUGH THE DRIVE THRU STOPPED AT THE FIRST WINDOW, ACCELERATED TO NEXT WINDOW (LOW SPEED) AND DIDN'T STOP... IT WAS THE LIKE THE BRAKES LOCKED UP, COULDN'T PRESS DOWN AT ALL. CALLED THE DEALERSHIP FIRST THING IN THE MORNING, SAME THING DIDN'T KNOW OF ANY ISSUES. WELL I GOOGLED IT AND IT IS UNDER INVESTIGATION, SO I KINDLY PRINTED OFF ALL THE ARTICLES SO THEY COULD LET OTHER CUSTOMERS KNOW THERE WAS AN ISSUE (THEY DIDN'T CARE TO KEEP THAT BUT DID ADMIT THEY KNEW THERE HAD BEEN SOME ISSUES). OF COURSE MY CAR IS JUST OUT OF WARRANTY SO THEY SAID I WOULD BE RESPONSIBLE FOR ANY ISSUES. AGAIN, THIS IS A SAFETY ISSUE AND THERE SHOULD BE A RECALL!!! THEY SHOULD BE PAYING FOR IT AND THANKING THERE LUCKY STARS NO ONE WAS INJURED. THE TOTAL CAME TO $950, THEY ASKED IF I WANTED THEM TO FIX THE PUMP, BELT AND BELT KIT (I ASKED IF THIS WAS THE ISSUE OTHERS WERE HAVING AND HE SAID HE BELIEVES SO). WHAT WAS I GOING TO SAY NO? DID I REALLY HAVE AN OPTION?? THE BRAKES WEREN'T WORKING!!!! KIND OF A BIG DEAL!! OF COURSE I WOULD LIKE THEM TO PAY ME BACK (THEY DID GIVE ME A CREDIT OF $208) BUT I DO BELIEVE THEY NEED TO DO A RECALL BEFORE SOMEONE GETS HURT.
