2015 GMC YUKON DENALI, BREAK LIGHT MALFUNCTION, DRIVING, PARKED WITH NO INDICATION WHEN IT WILL WORK OR NOT. DEALERSHIP AND GMC SERVICE CENTER CLAIMED THERE WERE NO OR VERY FEW COMPLAINTS HOWEVER I HAVE FOUND HUNDREDS ALREADY. THEY REFUSED TO EVEN LOOK AT THE LIGHT STATING I CAN GET IT REPLACED FOR AROUND $775 BECAUSE THEY CANNOT CHANGE BULBS ON THAT TYPE OF TAIL LIGHT. DEALERSHIP TOLD ME THAT THIS WAS NEW FEATURE STARTING WITH MY YEAR MODEL AND SINCE GMC WENT WITH ENCASED LED LIGHTS THEY NO LONGER CAN FIX THEM UNDER WARRANTY. THIS WAS NEVER DISCLOSED ANYWHERE AND GMC DOES NOT STATE THAT ANYWHERE I COULD FIND AND WILL NOT COVER IT UNDER FACTORY WARRANTY EVEN THOUGH IT IS OBVIOUSLY A WIRING ISSUE SINCE THE LIGHT DOES WORK SOMETIMES. I ALSO HAD PROOF WITH PICTURES THAT THE TAIL LIGHT DOES WORK SOMETIMES BUT NOT CONSTANTLY AND THE DEALER REFERRED ME TO GMC SERVICE CENTER. THE GMC SERVICE CENTER BASICALLY EXPLAINED THE SAME THING, THAT THEY HAVE NO RECORD OF COMPLAINTS AND THOSE WOULD NOT BE COVERED BECAUSE THE LIGHT IS ACTUALLY BROKE OR OUT, AND THAT IS NOT COVERED. THEY ACTUALLY SUGGESTED I GO BACK TO THE PURCHASING DEALERSHIP WHICH IS THE ONE THAT SENT ME TO THEM, JUST GOT THE GO AROUND WITH NO ACTION. THIS IS A SERIOUS SAFETY ISSUE IF THE LIGHTS STOP WORKING SUDDENLY, ESPECIALLY AT NIGHT BECAUSE THE WHOLE LIGHT GOES BLACK. NOW I CANNOT GET MY VEHICLE REGISTERED DUE TO THE LIGHT AND WILL NEED TO FIX OR REPLACE A FACTORY ISSUE WITH THE LIGHT JUST TO GET MY VEHICLE INSPECTED AND REGISTERED.

PASSENGERS SIDE BRAKE LIGHT WAS ONLY INTERMITTENTLY UNTIL IT QUIT ALL TOGETHER THEN THE DRIVERS SIDE DID THE SAME THING. I CALLED THE LOCAL DEALER ABOUT IT LAST YEAR AND THEY STATED THEY WERE NOT UNDER WARRANTY AND THE COST TO REPLACE THEM WAS OVER $800 EACH.

PASSENGER BRAKE LIGHT INCONSISTANLY WILL WORK ONE DAY THEN STOP WORKING. THE NEXT DAY IT WILL BE WORKING AGAIN. THE BRAKE LIGHT IS AN LED STRIP AND CANNOT BE REPLACED. THIS HAS BEEN GOING ON FOR MONTHS AND THE CAR HAS 10K MILES. WE NEVER KNOW IF AND WHEN THE LIGHT WILL BE WORKING. I HAVE BEEN TAKING PICTURES DOCUMENTING THE BRAKE LIGHT AND IT APPEARS TO WORK FOR 2 WEEKS THEN GOES OUT FOR A WEEK AND THEN COMES BACK ON FOR TWO WEEKS.

REAR PASSENGER BRAKE LIGHT STOPPED WORKING. INTERNET SEARCHES INDICATE THAT IT IS A FREQUENT PROBLEM WITH MANY COMPLAINTS. MOST NOTABLE IS THE DEALER COST TO REPLACE - $600 - $800 PER FIXTURE DUE TO IT BEING A SEALED UNIT AFTER WARRANTY HAS EXPIRED. GM NEEDS TO FIX THIS PROBLEM. A RECALL IS DEFINITELY IN ORDER.

NHTSA ODI 11130348

THE BRAKE LIGHTS CONTINUOUSLY WORK AND THEN DON'T WORK. THERE IS A MALFUNCTION WITH THE BRAKE LIGHTS IN THESE CARS. PLEASE REPORT YOUR ISSUES SO GM CAN STOP ROBBING US.

I GIVE!!! NOW BREAK LIGHTS NOT WORKING!!! RIGHT BREAK LIGHT IS OUT AND LEFT DRIVER IS INTERMITTENT. VEHICLE HAS 37K ON IT AND WAS JUST PICKED UP FROM THE DEALER AFTER HAVING 1 OF MANY ISSUES THROUGH THE PAST YEAR RECTIFIED AND NOW THIS! THIS IS A SIGNIFICANT SAFETY HAZARD AND COULD TREMENDOUSLY INJURE SOMEONE. RIGHT NOW MY CAR CANNOT EVEN PASS INSPECTION DUE TO THE FAULTY EQUIPMENT INSTALLED BY THE MANUFACTURE THAT IS A DANGER TO MY SAFETY. I HAVE OWNED MANY GMC'S (6 TOTAL) THROUGH THE YEARS AND THIS BEING THE WORST!! THE LATEST, I HAVE HAD THE TORQUE CONVERTER REPLACED IN AUG 18 - DUE TO SHUDDERING AND VIBRATION. THEN THE STEERING COLUMN REPLACED DUE TO POPPING , BACK HATCH HINGE REPLACED DUE TO POPPING AND MALFUNCTION, BACK GLASS DOOR RUBBER GASKET REPLACED DUE TO LEAKING, SHARKFIN ANTENNA REPLACED DUE TO LEAKING, SUNROOF GASKET REPLACED DUE TO LEAKING, NEW TIRES AT 500 MILES DUE TO EXCESSIVE VIBRATION. BACK DOOR ADJUSTED DUE TO SLAMMING, AND ADDITIONAL SLIGHT ISSUES. THE RADIO HAS A CONSTANT GLITCH ON THE SCREEN SINCE DAY ONE THAT AFTER BEING TAKEN IN NUMEROUS TIMES, OF COURSE THE DEALER CANNOT REPLICATE THE PROBLEM AND KEEPS PERFORMING A FLASH UPDATE WHICH NEVER HELPS AND AS SOON AS I DRIVE OFF IT GLITCHES AGAIN. I HAVE CONTACTED GM REGARDING THE BRAKE LIGHTS, RADIO, AND NOW MY PASSENGER STEP IS MALFUNCTIONING NOT TO MENTION A RECALL WAS JUST RELEASED ON THE POWER STEERING. WILL THE REPAIRS EVER END? GUESS ONCE I TRADE IT IN ON ANOTHER MANUFACTURE AS THIS WILL MOST LIKELY BE THE LAST GMC I WILL EVER PURCHASE!! I DO NOT HAVE TIME TO LIVE MY LIFE AT THE DEALER FOR A HIGH END PURCHASE THAT IS THE WORST MISTAKE EVER!! NOT TO MENTION BEING A SAFETY HAZARD!!!

VEHICLE CLUNKS OR HARD SHIFT WHILE SHIFTING VEHICLE FROM PARK TO DRIVE, OR PARK TO REVERSE. HAPPENS EVERY MORNING OR WHILE TRANSMISSION HAS COOLED DOWN. DEALER INDICATES THERE'S NO FIX FOR THIS CONDITION, NOT EVEN A UPDATE TO TRANSMISSION SOFTWARE.

NHTSA ODI 11130274

THE RIGHT REAR BRAKE LIGHT AND RUNNING LIGHT HAS GONE OUT. APPEARS TO BE A COMMON PROBLEM. YOU CAN'T REPLACE THE BULB LIKE OLDER CARS. YOU NEED TO REPLACE THE WHOLE BRAKE ASSEMBLY FOR $700!!! GM KNOWS ABOUT THE COMMON ISSUE BUT IS NOT COVERING IT.

WHEN USING STEERING TO TURN AROUND, TURN INTO A PARKING SPACE OR BACK IN, 'PARKING ASSIST OFF' SHOW UP ON THE INSTRUMENT PANEL, THEN THE STEERING WHEELS LOCKS AND THE CAR TURNS OFF WHILE STILL ENGAGED IN DRIVE. SOMETIMES 'BRAKE ASSIST' COMES ON FIRST. EXTREMELY DANGEROUS. WHEN THIS HAPPENS, UNABLE TO TURN STEERING WHEEL. CAR SHUTS DOWN AND DOORS LOCK. I HAVE TO PUT IT IN PARK AND RESTART THE CAR. SOMETIMES IT DOES IT MORE THAN ONCE AFTER RESTARTING THE CAR. I HAVE TAKEN IT TO A GMC DEALER FOR EVALUATION AND REPAIR. HAS HAPPENED AT LEAST 6 DIFFERENT TIMES. WHEN DRIVING, I AM ALWAYS AFRAID TO MAKE SHARP TURNS. HOWEVER, IT HAS ONLY HAPPENED AT SLOW SPEEDS WHEN TRYING TO TURN IN TO A DRIVEWAY OR TURN AROUND SUCH AS IN A PARKING LOT. *DT CONSUMER STATED AFTER TAKING MY CAR TO GMC DEALER AND BEING TOLD MY VEHICLE NEEDED A SORTWARE UPDATE, MY CAR WENT A FEW WEEKS WITHOUT AN EPISODE UNTIL THIS EVENING AT 7:52PM EASTERN TIME, WHILE BACKING IN TO MY DRIVEWAY. THE STEERING WHEEL KICKED IN PLACE AND THE VEHICLE TURNED OFF AND DOORS LOCKED, LEAVING ME OUT IN THE STREET, UNABLE TO CONTROL MY CAR FOR SECONDS. UPDATED 10/18/18*JB UPDATED 10/26/18*JB

THE PASSENGER TAIL LIGHT IS WORKING INTERMITTENTLY. THE DEALER SAID THAT THE ONLY FIX IS TO BUY A NEW BRAKE LIGHT UNIT @ $650. AFTER SEARCHING ON LINE, OTHER OPTIONS ARE TO SEND BRAKE LIGHT UNIT OFF FOR REPAIR, OR PURCHASE AFTER MARKET BRAKE LIGHT UNIT. AS MANY PEOPLE THAT ARE HAVING THIS SAME ISSUE, IT SURE SEEMS LIKE GMC WOULD CORRECT THIS FAULTY BRAKE LIGHT.

NHTSA ODI 11124171

THE REAR LED TAILIGHT GOES IN AND OUT, WHILE DRIVING THE CAR. THE DEALER WILL NOT FIX THE PROBLEM UNLESS THE LIGHT IS NOT WORKING, BUT BECAUSE IT IS INTERMITTENT, WE CANNOT GET IT TO FAIL AT THE DEALERSHIP. WE HAVE HAD THIS PROBLEM FOR 2 YEARS AND IT IS A SAFETY ISSUE AS THE TAIL LIGHT WILL NOT WORK.

NHTSA ODI 11123163

PASSENGER SIDE REAR BRAKE LIGHT AND TAIL LIGHT STOPPED WORKING. THIS CANNOT BE FIXED WITH A SIMPLE BULB. THIS IS AN INTEGRATED LED REQUIRING THE ENTIRE TAIL LIGHT ASSEMBLY TO BE REPLACED AT THE OWNERS EXPENSE. DEALER ESTIMATE WAS $800 AFTER INSTALLING.

NHTSA ODI 11123287

BRAKE LIGHTS HAVE FAILED. I APPEARS TO BE DUE TO A FAULTY SOLIDER ON THE LED ASSEMBLY. BOTH BRAKE LIGHTS HAVE NOW FAILED. THE FAULT IS CONSTANT AND HAS NO RELATIONSHIP TO STATUS OF THE OPERATION OF THE VEHICLE OR ROAD CONDITIONS. CONSUMER CAN NOT REPAIR THE FAULT DUE TO THE DESIGN OF THE TAIL LIGHT ASSEMBLY. THE VEHICLE OWNER AND OTHER DRIVERS ARE BEING ENDANGERED BY THIS ISSUE THAT IS OBVIOUSLY A QUALITY ISSUE WITH THE PRODUCT.

NHTSA ODI 11121588

BOTH REAR TAIL LIGHTS (BRAKE AND RUNNING LIGHTS) ARE NOT FUNCTIONING PROPERLY. THE PASSENGER SIDE ISN'T WORKING ALL TOGETHER AND THE DRIVERS SIDE WILL SOMETIMES BE ON AND OTHER TIMES NOT. THE DEALERSHIP WANTS $679 EACH SIDE FOR REPLACEMENTS. THIS SEEMS LIKE QUITE A BIG EXPENSE FOR A SAFETY ISSUE THAT GM NEEDS TO ADDRESS.

NHTSA ODI 11119597

LED BRAKE LIGHTS WENT OUT. WHEN I DID A SEARCH ON THIS PROBLEM, DISCOVERED THAT MANY OTHERS HAVING THE SAME PROBLEM WITH THEIR YUKONS. DEALERS CHARGING ASTRONOMICAL PRICES TO FIX. LEDS ARE SUPPOSED TO LAST LONGER THAN REGULAR BULBS. THESE LIGHT ASSEMBLIES HAVE A WELL KNOWN WEAK SPOT THAT CAUSES THEM TO GO OUT. GMC HAS COME UP WITH AN UPDATED ASSEMBLY. THEY SHOULD ISSUE A RECALL AND REPLACE THE ORIGINAL WEAK ASSEMBLIES WITH THE NEW ONES.

NHTSA ODI 11118231

RIGHT TAIL LIGHT (ONLY RED LIGHT) DOESN'T WORK. REVERSE LIGHT WORKS AND SIGNAL LIGHT WORKS ALL THE TIME BUT RED PART DOESN'T. IT WORKS AND THEN IT DOESN'T. IT DOES IT RANDOMLY.

NHTSA ODI 11118412

BRAKE PEDAL SUDDENLY GOT ROCK HARD WHEN I WAS TRYING TO SLOW DOWN, OUR TRUCK JUST KEPT GOING FORWARD, I WAS HELPLESS IN THAT SITUATION AND REALLY THOUGHT THAT ACCIDENT IS UNAVOIDABLE BECAUSE I WAS GETTING CLOSER AND CLOSER TO ANOTHER VEHICLE, AFTER PRESSING BRAKE PEDAL MANY MORE TIMES I WAS ABLE TO STOP OUR YUKON LITERALLY ONE INCH FROM A CAR IN FRONT OF ME

NHTSA ODI 11115892

AT LESS THAN 3 YEARS OLD BOTH TAILLIGHTS HAVE QUIT. THEY ARE A SEALED ASSEMBLY SO THE WHOLE SIDE NEEDS REPLACED. WE WERE QUOTED $750 EACH. OUR THREE YEAR OLD YUKON HAS NO TAILLIGHTS AND WILL TAKE $1500 TO REPLACE. I'M DISAPPOINTED IN GM TO SAY THE LEAST.
