WHEN SLOWLY TURNING INTO GARAGE, BRAKE PEDAL BECAME "HARD" AND REQUIRED SIGNIFICANT FOOT FORCE TO STOP THE VEHICLE. THE CONDITION HAS NOT IMPROVED AND I WILL HAVE TO TOW THE VEHICLE TO THE DEALERSHIP FOR REPAIRS.

WE BOUGHT OUR 2015 DENALI 1 YEAR AGO AND HAVE APPROX 50,000 MILES AND THE PASSENGERS SIDE TAIL LIGHT IS OUT. AFTER RESEARCHING TAILLIGHT PROBLEMS FOR MY MAKE AND MODEL THIS SEEMS TO BE A VERY COMMON ISSUE. THIS SHOULD BE CONSIDERED AS A RECALL BUT WHEN LOOKED INTO, I SEE IT IS NOT. ITS A SHAME TO SPEND SO MUCH MONEY ON A VEHICLE TO HAVE THE TAIL LIGHT OUT AT 3 YEARS (AFTER FACTORY WARRANTY IS ALREADY OUT) AND YOU HAVE TO REPLACE THE WHOLE TAIL LIGHT INSTEAD OF ONE PIECE.

WE OWN A 2015 GMC YUKON WITH ONLY 51,000 MILES ON IT. THE REAR TAILLIGHTS ARE BOTH INTERMITTENT. SOMETIMES THEY WORK, SOMETIMES THEY DON'T. I RECENTLY TOOK THE VEHICLE INTO THE DEALERSHIP FOR SERVICE AND THEY SAID REPLACEMENT OF THE ENTIRE LIGHT WAS THE ONLY WAY TO FIX THE ISSUE. THEY ACKNOWLEDGED THAT THIS IS A KNOWN ISSUE AND THAT THEY HAVE SERVICED MANY VEHICLES WITH THE SAME ISSUE. THE SERVICE PERSON ADVISED THAT THERE IS A CIRCUIT THAT OVER TIME BREAKS AND THE CONNECTION BECOMES LOOSE. WHEN THE METAL TOUCHES AND A COMPLETE CIRCUIT IS MADE, THE LIGHT WILL TURN ON. WHEN IT DOESN'T TOUCH (FAULTY), THE TAILLIGHT AND BRAKE LIGHTS WILL NOT ILLUMINATE. THIS IS A MAJOR SAFETY HAZARD. A SIMPLE INTERNET SEARCH SHOWS THAT THIS ISSUE IS VERY COMMON AND GM DOESN'T APPEAR TO BE DOING ANYTHING TO ADDRESS IT. BECAUSE IT INVOLVES THE BRAKE LIGHTS, THIS IS VERY CONCERNING. NOT TO MENTION, THAT A REPLACEMENT IS $800. I HAVE ALREADY SPENT $800 FOR ONE SIDE, NOW THE OTHER SIDE IS OUT AS WELL. I FEEL THAT THIS SHOULD BE A RECALL ISSUE SINCE IT'S AN OBVIOUS SAFETY ISSUE THAT IS CAUSED BY FAULTY PARTS. HERE IS JUST ONE OF THE LINKS THAT DESCRIBE THIS ISSUE IN DETAIL: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963

DRIVER SIDE REAR TAIL GAVE OUT TWICE AND DEALERSHIP OR GMC WON'T OVER WITH. THE DEALERSHIP THEM SELF SAID IT WAS FAULTY AND THEY BEEN HAVING LOTS OF PROBLEMS WITH THERE INVENTORY

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

I AM EXTREMELY DISAPPOINTED AT GENERAL MOTORS AT THE LACK OF QUALITY DESIGN IN THE REAR TAIL LIGHT LED ASSEMBLY. MY WIFE AND I HAVE OWNED GMC VEHICLES ALL OUR LIVES AND HAVE NEVER BEEN MORE DISSATISFIED WITH THE LACK OF QUALITY DESIGN IN THE REAR TAIL LIGHT LED DESIGN AND DESIGN LIFE. IN CONDUCTING RESEARCH THE LAST FEW DAYS, THIS HAS BEEN A CONSISTENT AND WELL DOCUMENTED DESIGN FLAW THAT GM STILL HAS NOT ADDRESSED. LED LIGHTING WHEN DESIGN PROPERLY IS SUPPOSED TO FUNCTION PROPERLY MUCH LONGER THAN STANDARD BULB INCANDESCENT LIGHTING. THIS CREATES A SAFETY ISSUE WITH OUR VEHICLE BECAUSE WE HAVE NO REAR LIGHTING AND THEN WE RECEIVE THE ESTIMATE FROM OUR DEALER "ROYAL BUICK GMC" AT OVER $1500. OBVIOUSLY, I AM FEELING SUCH FRUSTRATION BECAUSE MY REAR TAIL LIGHT ASSEMBLY'S ARE NOT FUNCTIONING PROPERLY ON MY WIFE'S **** GMC YUKON XL SLT. OF COURSE AFTER THE INITIAL WARRANTY HAS EXPIRED. COINCIDENCE, OR NOT VERY DISPLEASED? I WOULD LIKE SOMEONE CONTACT ME AT ***-***-**** OR BY EMAIL AND OFFER ASSISTANCE TO REPLACE THESE TAIL LIGHT ASSEMBLIES DUE TO THE QUALITY OR LACK THERE OF, IN THE PART. **SINCERELY DISGRUNTLED GM CUSTOMER!!! *TR

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.

THE BRAKE LIGHTS ON MY 2015 GMC YUKON XL HAVE BOTH GONE OUT. I HAVE BEEN PULLED OVER AND QUESTIONED ABOUT IT SEVERAL TIMES BY MY LOCAL LAW ENFORCEMENT. I BELIEVE THE MANUFACTURER STATE THAT THEY HAVE A LIFE OF 40,000 HOURS OF CONTINUOUS USE BUT, ONLY FUNCTION FOR A FRACTION OF THIS AMOUNT & THEY ARE $600-700 TO REPLACE.

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.

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

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 .

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

WHEN COMING TO A STOP, THE BRAKE PEDAL BECAME STIFF AND DID NOT ENGAGE. THIS HAS HAPPENED ON MULTIPLE OCCASIONS IN THE PAST, AND HAPPENS WHEN THE VEHICLE IS TRAVELING AT SLOW SPEEDS (LESS THAN 5MPH). THE ISSUE IS A FAULTY POWER BREAK PUMP.
