NHTSA ODI 11171646

REAR TAIL LIGHT STOPPED WORKING. I HAD JUST OVER 37K MILES ON MY VEHICLE WHEN IT HAPPENED, WHICH IS OUTSIDE GM'S WARRANTY. CALLED DEALER AND THEY TOLD ME ITS BEEN A RECURRING PROBLEM WITH THESE VEHICLES, BUT NO PLANS FOR GM TO RECALL OR REPAIR PART. WAS QUOTED OVER $700 TO REPLACE THE PART. ITS A FAULTY, CHEAP DESIGN AND MAJOR SAFETY ISSUE. THE CAR HAS NOT BEEN IN ANY ACCIDENTS AND BEEN DRIVEN ON STREETS AND HIGHWAYS ONLY. IT LOOKS BRAND NEW. HERE IS JUST 1 FORUM OF PEOPLE DISCUSSING THE SAME PROBLEM & A WORKAROUND FIX. HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963

REAR LED BRAKE LIGHTS ONLY WORK INTERMITTENTLY.

NHTSA ODI 11171162

MY TAILLIGHT STOPED WORKING. WHEN I TURN MY HEADLIGHTS ON IT WONT TURN ON OR WHEN I APPLY MY BRAKES. I SEARCHED THE INTERNET(FACEBOOK AND FOURM SITES) AND FOUND THOUSAND AND THOUSAND OF PEOPLE HAVING THE SAME ISSUES. THE BRAKE LIGHT/RUNNING LIGHT IS NOT A LIGHT BULB LIKE MOST CARS THAT YOU CAN JUST REPLACE WHEN IT GOES OUT. ITS LED.SO YOU HAVE TO REPLACE THE WHOLE ENTIRE LIGHT ASSEMBLY AND IT WAS OVER $800. LED ARE SUPPOSED TO HAVE A LONG LIFE BEFORE THEY GO OUT.... THIS IS ONLY A 2015 I MEAN COME ON. SO I HAD TO DRIVE IN THE DARK AND DURING THIS RAIN STORM ON FREEWAY AND REGULAR STREETS WITH NO BRAKE OR RUNNING LIGHTS WHICH I S EXTREMELY DANGEROUS. THIS IS A FAMILY VEHICLE I DRIVE MY KIDS IN THIS CAR. THIS CANT KEEP HAPPENING. I ALSO READ THAT MULTIPLE PEOPLE SAID ONCE THEY BOUGHT A NEW ASSEMBLY IT WENT OUT AGAIN AND STOPPED WORKING DOWN THE ROAD. THIS IS INSANE.

WHERE TO START, IT SEEMS GMC YUKON XL HAS BEEN HAVING A LOT OF ISSUES WITH ITS MODELS 2015-UP. IMAGINE DRIVING AT NIGHT AND ALL OF A SUDDEN ONE BRAKE LIGHT GOES OUT THEN A FEW MOMENTS LATER THE OTHER AS WELL. I HAVE READ MULTIPLE COMPLAINTS ABOUT THIS ISSUE ON GOING WITH GMC BUT NO RESPONSE TO RESOLVE THE ISSUE. HOW CAN THREE YEAR OLD SUV LOSE NOT ONE BUT BOTH BREAK LIGHTS AND YOUR STUCK OUT OF TOWN TRYING TO FIX OR FIND A RESOLVE. YOU CAN'T REPLACE THE BULB BUT NEED TO REPLACE THE WHOLE ASSEMBLY, GOD FORBID I WOULD OF BEEN DRIVING OR SOME HIT ME DUE TO BOTH BREAK LIGHTS GOING OUT. THIS ISSUE WITH THE BRAKE LIGHTS FOR THE GMC NEEDS TO BE ADDRESSED AND FIXED. YOU SPEND SO MUCH MONEY ON WHAT YOU THOUGHT WAS A GREAT VEHICLE ONLY TO REALIZE YOU PURCHASED A LEMON INSTEAD.

PASSENGER SIDE REAR TAIL LIGHT LED'S STOP WORKING, HAD TO REPLACE THE WHOLE UNIT. NOT WARRANTIED

TAKATA RECALL I BELIEVE THAT THE TAIL LIGHT SYSTEM OF GMC YUKONS 2015 AND ANY OTHER YEAR THAT SHARE THE SAME LIGHTING SYSTEM NEED TO BE RECALLED AND FIXED. MY ENTIRE REAR LIGHTING SYSTEM WENT OUT AND I DID NOT KNOW IT UNTIL SOMEONE STARTED HONKING THE HORN AT ME AND TOLD ME I HAD NO LIGHTS. SOMETIMES MY LIGHTS WORK AND SOMETIMES IT DOESN'T. MOST OF THE TIME IT IS ONLY ONE LIGHT. WE LOOKED ONLINE FOR OTHER PEOPLE HAVING THIS ISSUE AND IT SEEMS LIKE MANY PEOPLE HAVE THIS SAME ISSUE AND THE PROBLEM OF IT IS A DEFECT WHERE A PIECE INSIDE THE LIGHT BREAKS AND CAUSES CONNECTION ISSUES. I HAVE SEEN (ON YOUTUBE) MANY PEOPLE FIXING THE ISSUE BY SAUNTERING IT TOGETHER. THIS COULD BE VERY DANGEROUS. DRIVING WITHOUT ANY LIGHTS. IT IS ALSO VERY COSTLY TO BUY NEW LIGHTS THAT WILL EVENTUALLY DO THE SAME THING. THE ISSUE HAPPENS ALL THE TIME ONCE IT STARTS. THE ONLY TIME MY REAR LIGHTS WORK 100 PERCENT OF THE TIME NOW IS WHEN IT IS COLD OUTSIDE. I HAVE BEEN TOLD IT IS BECAUSE THE COLD CAUSES THE PLASTIC TO SWELL AND IT MUST CONNECT THE PIECE INSIDE THE LIGHT .

WHEN TOWING A SMALL CAMPER AND TRAVELING AT SLOW SPEEDS MY BRAKE BECOMES HARD AND MUST BE PRESSED VERY HARD TO SLOWLY STOP THE CAR. THIS DOES NOT HAPPEN ALL THE TIME BUT HAS HAPPENED MULTIPLE TIMES AND IS QUITE SCARY. THE VEHICLE TRAVELS FURTHER BEFORE STOPPING THAN WITH PROPER BRAKING WHICH HAS THE POTENTIAL OF PUTTING ME IN A DANGEROUS SITUATION. DEALER SAYS IT IS A VACUUM PUMP BEGINNING TO FAIL BUT THERE ARE NO PUMPS AVAILABLE NATIONWIDE SO I CANNOT HAVE IT REPAIRED! NOTES ABOUT DATES AND MILEAGE ARE FOR THE LAST OCCURRENCE AND AS CLOSE AS I CAN RECALL FOR EACH.

REAR LED TAIL LIGHTS STOP WORKING DUE TO CRACKED BRIDGE ON CIRCUIT BOARD OF LIGHT ASSEMBLY.....NON SERVICEABLE NEW TAIL LIGHT IS $600-$700. POSSIBLE COLLISION HAZARD!

I HAVE NOW HAD MY 3RD LED LIGHT GO OUT ON MY YUKON XL 2015 THE FIRST WAS THE PASSENGER HEAD LIGHT THEN THE PASSENGER TAIL LIGHT AND NOW THE DRIVER TAIL LIGHT

NHTSA ODI 11165357

WE HAD A TAILLIGHT GO OUT AT 70,000 MILES. THE WHOLE UNIT HAD TO BE REPLACED AND WE PAID OVER $900 THROUGH A GMC DEALER. THEN WE HAD THE OTHER TAILLIGHT GO OUT AT 88,000 MILES. IT COST $1000 TO REPAIR. WE'VE RECENTLY REASEARCHED THE ISSUE ONLINE AND IT SEEMS TO BE EXTREMELY COMMON ON THIS SPECIFIC VEHICLE AND MOST PEOPLE AND REPUTABLE ELECTRICIANS HAVE STATED THAT IT'S A RESULT OF A FAULTY PART IN THE UNIT.

ON TWO SEPARATE OCCASIONS WHEN PARKING, AND DRIVING AT A HIGH RATE OF SOEEDV( 60 MPH)ON INTERSTATE IN SUDDEN STOP AND GO TRAFFIC BRAKES FAILED TO ENGAGE AFTER WORKING PROPERLY BEFORE AND AGAIN AFTER WITH MORE THAN A MONTH BETWEEN INCIDENTS . THE SECOND INCIDENT OCCURRED ON 12/31/18 AFTER THE VEHICLE HAD BEEN IN FOR ROUTINE OIL CHANGE AND SERVICE THAT INCLUDED A MULTI POINT INSPECTION AT THE GMC DEALERSHIP WHERE IT WAS PURCHASED BRAND NEW. THE VEHICLE IS FREQUENTLY SERVICED AS REQUIRED AND HAS TIRES WITH GOOD TREAD . THE FAILURE IS ALARMING AS IT OFTEN COMES WHEN TRYING TO MAKE A NECESSARY STOP AND THE FAILURE COMES OUT OF THE BLUE THEN RETURNS TO NORMAL. THIS OCCURRENCE SHOULD BE ADDRESSED BY THE MANUFACTURER AND SHOULD BE TAKEN VERY SERIOUSLY SINCE THE MATTER IS LITERALLY A MATTER OF LIFE AND DEATH. I WILL BE MAKING AN APPOINTMENT FOR MY VEHICLE TO BE CHECKED OUT AND WILL UPDATE THE DEALERSHIP FINDINGS .

MY RIGHT REAR TAILLIGHT STOPPED WORKING, INCLUDING THE BRAKE LIGHT. I TOOK IT TO THE DEALERSHIP AND WAS TOLD IT IS A BURNED OUT TAILLIGHT AND HAS TO BE REPLACED. THE COST WAS $800. I WAS UNDER THE IMPRESSION THAT THESE TAILLIGHTS ARE LED AND LAST FOREVER. IN READING ONLINE, IT LOOKS LIKE THIS IS AN ONGOING PROBLEM WITH THESE GMC/CHEVY TAILLIGHTS WHERE THE CIRCUIT BOARD BREAKS AND THE LIGHT STOPS WORKING.

BRAKE LIGHTS WORKING INCONSISTENTLY,

NHTSA ODI 11162896

THE VEHICLE'S TAIL LIGHT ASSEMBLY ON BOTH THE DRIVERS AND PASSENGER'S SIDES ARE DEFECTIVE. THE SOLDER DOES NOT HOLD AND THE VEHICLE'S BRAKE LIGHTS AND RUNNING LIGHTS FAIL INTERMITTENTLY. THE DRIVER IS TOTALLY UNAWARE OF THIS MAJOR ISSUE THAT THE BRAKE LIGHTS ARE NOT WORKING. IN RESEARCHING THIS PROBLEM ON THE INTERNET THERE ARE NUMEROUS CUSTOMERS OF GMC'S YUKON'S AND DENALI'S WHO ARE EXPERIENCING THE SAFETY PROBLEM. I REALIZED THE PROBLEM WHEN ANOTHER MOTORIST ALMOST STRUCK THE BACK OF MY VEHICLE BECAUSE THERE WERE NOT BRAKE LIGHTS AT ALL. THE VEHICLE WAS TRAVELING AND BOTH BRAKE LIGHTS FAILED. THE SIGNAL LIGHTS WILL STILL WORK.

WE WERE STOPPED AT A RED LIGHT TODAY BY SOMEONE TELLING US OUR TAIL LIGHT WAS BLINKING AND GOING OUT. OUR VEHICLE ONLY HAS 65000 MILES! I WOULD THINK A LED LIGHT SHOULD NOT GO OUT YET. MY VEHICLE SITS UNDER A CARPORT WHEN NOT IN USE. I HAVE SEEN NUMEROUS COMPLAINTS ONLINE FOR THIS SAME PROBLEM FOR SAME YEAR MODEL

POWER BRAKES FAILING AT LOW SPEEDS-IN FREEWAY TRAFFIC-PULLING INTO DRIVEWAY REQUIRES STRONG PRESSING ON BRAKE PEDAL AS IF THE BRAKES ARE INTERMITTENTLY LOOSING POWER ASSIST

NHTSA ODI 11160672

AT SLOW SPEED IN STOP AND GO TRAFFIC THE BRAKES WILL WORK ONE TIME AND THE NEXT TIME I WOULD HAVE TO STOMP THE BRAKE PEDAL TO GET THE SUV TO STOP IT WAS ON A STREET WHEN IT HAPPENED I HAVE TRIED TO CONTACT FLOW GMC OF WINSTON-SALEM MULTIPLE TIMES AND CAN'T GET ANYONE TO TALK TO ME

NHTSA ODI 11160740

BRAKE LIGHTS WENT OUT ON BOTH SIDES. ALL OTHER LIGHTS IN UNIT ARE FUNCTIONING FINE. GMC IS REQUIRING ME TO BUY THE ENTIRE LIGHT WHICH IS $750 EACH JUST TO FIX THE BRAKE LIGHT. BOTH LIGHTS WENT OUT AT THE SAME TIME. HAS TO BE AN ISSUE WITH THE LIGHT

LEFT REAR TAIL LIGHT QUIT WORKING, I WAS ABLE TO BREAK THE COVER OFF AND SOLDERED THE LED MOUNTING STRIP,. RIGHT SIDE QUIT WORKING SO I BROKE THE COVER OFF BUT THIS TIME IT WAS SEVERELY DAMAGED. SOLDERED IT. LEFT SIDE QUIT WORKING AGAIN SO I REPLACED BOTH SIDES WITH AFTERMARKET UNITS. DATE BELOW IS JUST TO FILL THE SPACE. IT WAS AFTER WARRANTY EXPIRED AND OVER ABOUT 6 MONTHS TIME.

ON MULTIPLE OCCASIONS SPECIFICALLY WHILE TRAVELING AT LOW SPEED RATE SUCH AS SLOW MOVING TRAFFIC OR PULLING IN OR BACKING OUT OF PARKING SPACE. THE BRAKES BECOME HARD TO PUSH AND THE BRAKES DO NOT ENGAGE. YOU MUST PUSH THE BRAKES VERY HARD TO STOP. WE TOOK TO THE GM SERVICE AT OUR DEALERSHIP AND A BRAKE VACUUM PUMP WAS REPLACED. THE NEXT DAY WE WERE DRIVING THE VEHICLE AND THE BRAKES FAILED TO STOP. THANKFULLY WE WERE IN A PARKING LOT AND WERE ABLE TO STOP AGAINST BUMPER STOP. WE CALLED THE GM SERVICE DEALERSHIP AND THEY ARRANGED FOR A TOW. THIS IS EXTREMELY DANGEROUS SITUATION.

NHTSA ODI 11155677

THE REAR TAILLIGHT WORKS INTERMITTENTLY. I HAVE REPORTED IT TO THE DEALERSHIP AND THE ONLY FIX IS TO REPLACE THE HOUSING UNIT AT $1500. IT HAS BEEN REPORTED AND IS A KNOWN PROBLEM WITH GMC.
