What 977 owners told NHTSA about the 2015 GMC Yukon Denali Xl 1500

TAIL BRAKE LIGHT IS OUT. VEHICLE HAS NOT BEEN IN ANY TYPE OF ACCIDENT.

NHTSA ODI 11204562

THE BRAKE LIGHTS WORK SOMETIMES AND THEN DON'T, THIS IS A HUGE ISSUE. IF THEY STOP WORKING WHILE DRIVING THIS COULD KILL ME OR ANOTHER DRIVER OR SOMEONES PASSENGER(S).

NHTSA ODI 11204639

THERE ARE NUMEROUS CUSTOMERS THAT ARE EXPERIENCING PROBLEMS WITH THE TAILLIGHTS ON THE YUKON DENALI XL. GMC IS NEGLIGENT DUE TO THE FACT THAT THIS PROBLEM IS A SAFETY HAZARD AND NO RECALL HAS BEEN INITIATED.

I PURCHASED A 2015 GMC YUKON AND AM THE SECOND OWNER. LAST WEEK, MY DRIVER'S SIDE BRAKE LIGHT WENT OUT. I NOTICED IT WHILE DRIVING WHEN SOMEONE BEHIND ME TOLD ME IT WAS OUT. SIX MONTHS AGO, I REPLACED THE PASSENGER SIDE BRAKE LIGHT WHICH COST $875 TO FIX (THE ENTIRE LIGHT ASSEMBLY MUST BE REPLACED, NOT JUST A BULB). A LITTLE RESEARCH ONLINE HAS PROVEN THAT THIS SEEMS TO BE A COMMON PROBLEM FOR MANY OTHER GMC YUKON OWNERS. LED LIGHTS ARE SUPPOSED TO LAST THE LIFETIME OF THE VEHICLE, BUT IT WOULD APPEAR THAT SOMETHING ABOUT THE PRODUCT IS DEFECTIVE. THIS IS SIMPLY OUTRAGEOUS AND GMC KNOWS THAT IT IS A PROBLEM.

BRAKE LED LIGHTS GO OUT AND ON, SOMETIMES ONE SIDE WORKS, THEN OTHER TIMES THE OTHER SIDE GOES OUT, AND SOMETIMES BOTH BRAKE LIGHTS DO NOT WORK. SOMETIMES BY BANGING THE COVER, IT TURNS ON AND WORKS, BUT THEN THEY GO OUT.

NHTSA ODI 11202715

BOTH REAR TAIL LIGHTS HAVE GONE OUT.

NHTSA ODI 11197341

ALL BREAK LIGHTS STOPPED WORKING AT THE SAME TIME ON BOTH SIDES OF VEHICLE. TURN SIGNAL, BACK UP LIGHTS, BLINKERS ALL STILL WORK. I WAS TOLD THE ENTIRE BREAK LIGHT HAD TO BE REPLACED FOR A COST OF APX 2K. IT SEEMS THAT THIS IS A VERY COMMON PROBLEM AND THE COST OF REPAIR IS ASTRONOMICAL.

NHTSA ODI 11202543

REAR LIGHTS, TAIL LIGHTS STOPPED WORKING. YOU CANT JUST CHANGE THE BULB. BEING LEDS THE WHOLE PIECE HAS TO BE CHANGED. APPARENTLY THIS IS A KNOWN ISSUE AND GM KNOWS ABOUT IT, YET THERES BEEN NO RECALL??

NHTSA ODI 11202551

LEFT REAR TAIL LIGHT (LED) AND BREAK LIGHT FAILURE. NOT A BULB BUT THE CIRCUIT FAILED. BUMPER TO BUMPER WARRANTY WOULD NOT COVER BULBS, BUT THIS WAS NOT A BULB FAILURE! I WOULD LIKE TO APPEAL THIS DENIAL

NHTSA ODI 11197146

RIGHT SIDE /PASSENGER BRAKE LIGHTS FAILED. DEALER SAYS IT'S A CRACKED ELECTRICAL BOARD. THEY SAID THAT THEY HAVE SEEN TONS OF THESE AND IT'S NOT UNDER WARRANTY. $1300 DEALER REPAIR ESTIMATE. THIS SHOULD BE A RECALL ISSUE.

NHTSA ODI 11197205

THE DRIVER'S SIDE BRAKE LIGHT HAS STOPPED WORKING. UPON FURTHER INVESTIGATION IT WAS DETERMINED THAT THE LED CIRCUIT BOARD WAS BROKEN. A WEB SEARCH INDICATES THAT THIS IS A COMMON PROBLEM WITH THIS VEHICLE AS THE CIRCUIT BOARD IS CHEAPLY MADE. THE BRAKE LIGHT CANNOT BE SIMPLY REPLACED. THE ENTIRE REAR LIGHT COMPONENT (BRAKE LIGHT, RUNNING LIGHTS, TURN SIGNAL) NEEDS TO BE REPLACED TO REPAIR THIS. THE COST TO REPLACE IS ~$500. THIS PART SHOULD BE RECALLED AND REPLACED WITH A LED LIGHT BOARD THAT IS STRONGER AND LASTS LONGER THAN 4 YEARS.

NHTSA ODI 11196766

I HAVE REPLACED THE PASSENGER SIDE TAILIGHT AND NOW THE DRIVER SIDE TAILIGHT IS NOT WORKING. THE TURN SIGNAL AND REVERSE LIGHT WORK BUT THE RED PART OF THE LIGHT WILL WORK AND THEN GO OUT.

NHTSA ODI 11196123

REAR PARKING/BRAKE LIGHT WENT OUT. DEALER SAYS THE FIX IS $800 PLUS LABOR TO FIX.

NHTSA ODI 11196009

MY GMC YOUKON DENALI HAS BRAKE LIGHTS THAT ARE KNOWN TO DEALERS TO FAIL. YET THERE IS NOT A RECALL. I LOOKED ON THE INTER NET AND SAW THAT THERE HAS BEEN THIS PROBLEM SINCE 2015 TO 2018. BECAUSE OF A JOINT THAT WAS SOLDERED INSTEAD OF A WIRE. I KNOW WHY WHEN I BROUGHT IT IN FOR RECALL THAT THE SERVICE MAN LOOKED AT MY STOP LIGHTS.

NHTSA ODI 11195738

TAILLIGHTS WORKING INTERMITTENT. THIS IS A SAFETY ISSUE. I HAVE GOOGLE AND THERE OVER A 100 COMPLAINTS ON CAR GURUS WITH THE SAME PROBLEM. THIS IS A GMC SAFETY PROBLEM. THESE YUKON'S ARE EXPENSE AND I SHOULD FEEL SAFE WHILE DRIVING IT. TAKING IT TO THE DEALERSHIP THIS MORNING. I AM ASKING A CUSTOMER OF GMC--- DO THE RIGHT THING AND LOOK INTO THIS AS SOMEONE IS GOING TO GET KILLED - NO TAILLIGHTS COULD BE A LIFE THREATING SAFETY ISSUE. GMC DO THE RIGHT THING. LOOK AT ALL OF THE COMPLAINTS WITH THE EXACT SAME ISSUE

NHTSA ODI 11194525

THE LED BRAKE LIGHT WENT OUT THERE SEEMS TOO BE FAULTY ELECTRICAL AND COMPANY KNOWS IT

NHTSA ODI 11194342

THE REAR DRIVER SIDE TAILLIGHT DOES NOT WORK. TOOK IT TO THE DEALERSHIP AND THEY SAID IT WAS A PROBLEM THEY SAW FREQUENTLY, TO JUST HIT THE LIGHT AND IT MIGHT START WORKING. OTHERWISE IT WAS A 800 DOLLAR LIGHT TO REPLACE....IF IT IS A FREQUENT PROBLEM GMC SHOULD BE FIXING IT... ARE THEY GOING TO PAY FOR A TICKET IF I GET PULLED OVER OR WORSE SOMEONE CRASHES INTO ME? THE PROBLEM COMES AND GOES BUT HAS SEEMED TO GET WORSE AND IS NOT SAFE OR LEGAL TO DRIVE WITH THE LIGHT HOW IT IS. BAD DESIGN OF THE LIGHT. AND FROM WHAT I HAVE SEEN ONLINE I AM NOT THE ONLY ONE. THERE A WHOLE FORUMS THAT PEOPLE HAVE THE SAME ISSUE.

NHTSA ODI 11194118

REAR BREAK TAILIGHTS DO NOT WORK AT ALL TIMES. MOST OF THE TIME THEY REQUIRE TAPPING ON THE TAILLIGHT TO GET THEM TO LIGHT THE TAIL LIGHT. NOT A BULB ISSUE AND SEEMS TO BE A COMMON PROBLEM WITH ALL YUKON'S OF THIS MAKE. VERY FRUSTRATING TO HAVE THEM WORK INCONSISTENTLY . SOMETIMES ONE LIGHT OUT AND SOMETIMES BOTH.

NHTSA ODI 11193641

WITHIN THE LAST YEAR ON MY 2015 MY AC COMPRESSOR HAS GONE OUT, RADIO SCREEN QUIT WORKING, BRAKE PUMP/BOOSTER FAULTY, AND NOW REAR BRAKE LIGHT QUIT WORKING. ALL SEEM TO BE VERY COMMON IN THIS YEAR MODEL. MY CAR HAS LESS THAN 70000 MILES ON IT!! GM IS EITHER DOING A CRAPPY JOB ON THEIR $60000 VEHICLES OR A RECALL NEEDS TO BE DONE.

NHTSA ODI 11193726

PASSENGER SIDE BRAKE AND TAIL LED STRIP LIGHT SHORT AND GOES OUT AND STOPS WORKING. WILL WORK SOMETIMES WHEN BACK HATCH SHUTS AND JARS IT OR I HIT A BUMP. DEALERSHIP SAYS LIGHT IT OUT AND NEEDS REPLACING. NOT SURE WHY THE LIGHT STILL COMES ON WHEN JARRED. HAVE EXTENDED WARRANTY THAT WAS SUPPOSED TO COVER ALL THIS ESPECIALLY BEING ELECTRICAL. SEEMS TO BE ON GOING PROBLEM

NHTSA ODI 11192871

DRIVER SIDE TAILLIGHTS ARE BROKEN. PASSENGER SIDE TAILLIGHTS ARE FAILING NOW. NEITHER TAILLIGHTS NOR BREAK LIGHTS ARE FUNCTIONING PROPERLY ON THE DRIVER SIDE AND THE TAIL LIGHTS ARE STARTING TO FAIL ON THE PASSENGER SIDE

NHTSA ODI 11193128

PASSENGER SIDE REAR TAIL LIGHT/ BRAKE LIGHT INOPERABLE. PROBLEM OCCURRED AT 44,580 MILES.

NHTSA ODI 11192745

APPROXIMATELY 51,000 MILES ON VEHICLE: REAR PASSENGER TAIL LIGHT IS INOP. WE WERE ON A TRIP WHEN WE NOTICED, IF YOU TAP THE SIDE OF IT THE LIGHT WOULD COME ON FOR JUST A SECOND. LED STRIP FOR BRAKE LIGHT IS DEFECTIVE. REPLACEMENT COST IS ABOUT $800 DOLLARS. LOTS OF COMPLAINTS AND ONLINE FORUMS REGARDING THIS ISSUE. GMC REALLY NEED TO RESOLVE THIS ISSSUE. THESE RIGS COST WAY TO MUCH FOR THAT POOR QUALITY!

NHTSA ODI 11192777

I HAVE 47,000 MILES ON MY YUKON SLT. I REPLACED THE HIGH PRESSURE FUEL PUMP ABOUT TWO WEEKS AGO FOR A PRICE OF $1,400. NOW MY DRIVER SIDE BRAKE LIGHT WENT OUT. DEALER IS TELLING ME NEARLY $800 TO FIX. I PAID GOOD MONEY FOR THIS CAR AND HAVE HAD NOTHING BUT PROBLEMS.

NHTSA ODI 11192802

THERE IS A FLAW IN THE LED STRIP OF THE REAR TAIL LIGHTS. THE LED STRIP BREAKS OVER TIME DISABLING THE TAIL LIGHTS. THE TAIL LIGHT ASSEMBLY IS SEALED AND MUST EITHER BE REPLACED OR BROKEN INTO SO A JUMPER CAN BE SOLDERED ACROSS THE BREAK TO REPAIR THE TAIL LIGHT.
