2015 GMC YUKON Complaints

REAR LED TAILLIGHTS WORK INTERMITTENTLY. FOUND SEVERAL FORUMS WHERE THIS HAPPENS TO A LOT OF PEOPLE. IF YOU TAP THE TAILLIGHT IT SOMETIMES BEGINS WORKING AGAIN. TRUCK ONLY HAS 60K MILES AND GM WANTS OVER $1200 TO FIX (REPLACE BOTH TAILLIGHTS). EVIDENTLY THERE'S A CIRCUIT BOARD THAT GOES BAD INSIDE. I HAD THIS AT GM TO BE FIXED BUT BECAUSE TAILLIGHTS WERE WORKING AT THE TIME, THEY FOUND NO PROBLEM.

REAR TAIL/BRAKE LIGHT FAILED AFTER FUNCTIONING INTERMITTENTLY FOR A MONTH. GMC DEALER REPLACED THE ENTIRE ASSEMBLY WITH A NEW GM PART AT A COST OF OVER $800. GMC DEALER EXPLAINED THAT DESPITE CHRONIC FAILURES OF THIS PARTICULAR PART, GM REFUSES TO RECALL. FAILURE APPEARS TO RESULT FROM A FAULTY CIRCUIT BOARD THAT CANNOT BE REPLACED OR REPAIRED EASILY. INTERMITTENT NATURE OF THE FAILURE IS AN UNSAFE CONDITION, ESPECIALLY AT NIGHT OR IN FOUL WEATHER.

REAR BRAKE LIGHT ASSEMBLY FAILING TO LIGHT WHEN BRAKES APPLIED AND THERE IS NOT A NOTIFICATION TO THE DRIVER. THIS IS A MANUFACTURE FLAW WITH THE LED LIGHT CIRCUIT INSIDE THE ASSEMBLY. THERE IS NOT A LIGHT OUT NOTIFICATION SO THE DRIVER IS NOT AWARE THE BRAKE LIGHT HAS FAILED. THIS IS A SAFETY ISSUE AND IS AN WELL KNOWN ISSUE ON THE 2015-2019 YUKON. THIS IS OCCURRING OFTEN AND GMC IS HAVING PROBLEMS WITH SUPPLYING REPLACEMENTS BECAUSE THE DEMAND IS SO HIGH FROM THE FAILURE. GMC HAS ALSO RAISED THE PRICE OF THE BRAKE LIGHT BY 30% FROM $425 TO $675 NOT INCLUDING LABOR. I CALLED THE DEALER AND THEY INFORMED IT WAS A HIGH FAILING ITEM AND WAS ON BACKORDER AND NOT SURE WHEN THEY WOULD GET ONE. DRIVING THE VEHICLE WITHOUT PROPER BRAKE LIGHTS IS A SAFETY CONCERN AND NOT LEGAL SO LEFT WITH LITTLE OPTION BUT TO STOP DRIVING THE YUKON.

PURCHASED VEHICLE (USED) FROM DEALER LESS THAN 2 YEARS AGO. DRIVER TAILLIGHT WENT OUT. NOT COVERED UNDER WARRANTY BUT IS A SAFETY ISSUE THAT ACCORDING TO SEVERAL FORUMS IN A KNOWN PROBLEM. THE TAILLIGHT IS ARCHITECTED, ENGINEERED, AND BUILT IN SUCH A WAY AS TO BE VERY EXPENSIVE TO REPLACE, BREAK OFTEN, AND DISCOURAGE DIY OR NON-DEALER REPAIRS. THE VEHICLE WAS STATIONARY WHEN THE PROBLEM WAS NOTICED.

SOMEONE WHO WAS DRIVING BEHIND ME TOLD ME MY DRIVER'S SIDE BRAKE LIGHT WAS OUT. I CHECKED IT WITH THE HELP OF SOMEONE ELSE A COUPLE TIMES AFTERWARDS AND IT WORKED. THEN A WEEK OR SO LATER A CO-WORKER TOLD ME THE SAME THING, THAT IT WAS OUT. I CHECKED IT AGAIN LATER AND IT WORKED, SO THE PROBLEM WAS INTERMITTENT. WHEN I TOOK IT TO THE DEALER, THE TAILLIGHT ASSEMBLY HAD TO BE REPLACED. I JUST PURCHASED THE VEHICLE 1/7/2019 AND BEFORE IT WAS OFFERED FOR SALE THE PASSENGER-SIDE TAIL LIGHT ASSEMBLY WAS ALSO REPLACED.

TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT THE REAR DRIVER'S SIDE BRAKE LIGHT AND PASSENGER SIDE TAIL LIGHT WERE BURNED OUT. THE CONTACT STATED THAT THE BRAKE LIGHTS WOULD NOT ILLUMINATE. THE VEHICLE WAS TAKEN TO ED BOZARTH CHEVROLET (2001 S HAVANA ST, AURORA, CO 80014, (720) 746-2716) AND JOHN ELWAY CHEVROLET (5200 S BROADWAY, ENGLEWOOD, CO 80113, (720) 259-0391), BUT THE PARTS WERE NOT AVAILABLE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND PROVIDED A CASE NUMBER. THE FAILURE MILEAGE WAS 81,000.

REAR BRAKE AND TAIL LIGHTS DO NOT WORK INTERMITTENTLY. SOMETIMES THE LIGHTS WORK AND SOMETIMES THEY DON'T.

WHILE SITTING STILL AT A DRIVE THROUGH, BRAKE PEDAL WENT TO FLOOR AS IF IT HAD NO PRESSURE. HAD NO BRAKES! NO MATTER HOW HARD I STOOD ON PEDAL THE CAR WOULD NOT COME TO COMPLETE STOP WHEN ROLLING. BLEW THROUGH STOP SIGNS AND LIGHTS BECAUSE EVEN AT 10 MPH COULD NOT STOP VEHICLE FROM ROLLING. HAD JUST GOT OFF INTERSTATE DOING 70 MPH. DOWN HILL GRADE WAS IMPOSSIBLE. FOUND OUT THAT THIS WAS A KNOWN ISSUE BY GM INVOLVING FAILURE OF VACUUM PUMP BOOSTER. MANY REPORTS, HOPEFULLY NOT MANY DEATHS CAUSED.

2015 GMC YUKON DENALI REAR TAIL LIGHTS FAIL DUE TO DEFECTED PARTS. GMC WILL NOT REPLACE THE FAILED PARTS WHICH IS A KNOW SAFETY ISSUE. NUMEROUS COMPLAINTS ONLINE WITH THE GMC YUKON 2015-2019 MODELS.

TAIL LIGHT MALFUNCTION INTERMITTENTLY. THE TAIL LIGHTS AND BRAKE LIGHTS OCCASIONALLY WILL GO OUT AND COME BACK ON RANDOMLY. GMC KNOWS ABOUT THE ISSUE AND REPLACEMENTS COST ABOUT $750 PER UNIT WHICH EVEN THESE REPLACEMENTS HAVE BEEN KNOWN TO FAIL WITHIN A YEAR. THE FACT THAT THIS HAPPENS RANDOMLY AND SO INTERMITTENTLY THIS BECOMES A SAFETY ISSUE. I'VE HAD IT IN THE SHOP AND THEY SAID NOTHING WAS WRONG BECAUSE THEY WERE BOTH WORKING. I GET HOME AND THEY ARE NOT. IS THERE A WAY TO HAVE GMC REPLACE THESE VIA A SAFETY RECALL?
