Breaks are faulty, lights continue to go out in the rear after only a year after purchase. I’ve read other complaints about these issues. could be wiring or electrical issue with the breaks. Engine sounds like a plane is about to take off, has had starting problems. Overall horrible vehicle. There are a lot of problems with the vehicle, the lights are extremely dangerous as person behind would not know if I’m stopping when they fail to work and can cause a serious accident. Engine is a major concern as well.

Driver side brake lights don't work again. This will be the 3rd time that I know of that this piece of equipment has been changed out.

NHTSA ODI 11432765

Right brake light and tail light quit working for a few days, then returned to normal operation, both worked fine for a week then the left side went out and also returns for a few days. Now both are out except for one led per side per cluster. No brake lights except for the one over the gate. And turn signals work as they should.

Tail Lights don't work. Have seen several complaints about this problem. There is currently a lawsuit concerning this. GMC will only cover replacement if car has less than 72,000 miles. The replacement lights cost about $800 each. Having it looked at now. Fear that I will have to pay replacement costs.

The contact owns a 2015 GMC Yukon Denali XL. The contact stated that the passenger’s side taillight failed to illuminate intermittently while depressing the brake pedal. Over time, the driver’s side taillight also would fail to illuminate with the brake pedal depressed. The contact then received a warranty notice from the local dealer about the failure however, the contact was informed when speaking to the dealer that due to the mileage on her vehicle, the vehicle no longer qualified under the warranty program. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 40,000.

LED Brake Lights fail due to design error typically on both side of the vehicle. I have found multiple reports of a failure on a circuit board that was poorly designed. A copper tracing is very narrow and fractures due to vibration resulting in Brake Light failure. Because the entire module must be replaced the repair costs $800-$900 per side.

Tail lights are not functioning properly. N182180270 was issued due to very common issue but no recall. The special adjustment only covers up to 72,000 miles. I now have 106,000 so not covered? Serious safety issue if brake lights are malfunctioning and GM aware of issue. If technician checking lights and they are intermittently working, then I drive away from dealer and they intermittently no longer work, that is a serious safety issue and a recall should happen. I took my vehicle in for an oil change and on the drive to have serviced I was told by my wife driving behind me that the right rear brake light wasn’t working. I asked tech to check. Technician confirmed but states left isn’t working either. Yet on drive to drop the vehicle for oil change the left was working. And we have a time stamped photo as proof(attached). I had someone tell me right rear brake light was out a couple of years ago but when I had it checked, all were on. So when are they working? When are they not working? And that is why a recall should be issued. correct a faulty design. These aren’t an easy fix of replacing a bulb. The whole unit has to be replaced at $700+ each. How many people are out there driving with these intermittent brake lights? We periodically check our lights to ensure working. But if these lights are on/off intermittently, that does very little good. Scary!

Drivers side tail light intermittently works, doesn't work all the time. Passenger side brake light stays on continuously, never changes.

THE CONTACT OWNS A 2015 GMC YUKON XL. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE CONTACT WAS ALERTED BY HER HUSBAND WHO WAS DRIVING BEHIND THE VEHICLE, THAT THE REAR TAIL LIGHTS WERE INOPERABLE. THE CONTACT WAS ALSO ALERTED BY OTHER DRIVERS THAT THE REAR TAIL LIGHTS WERE NOT FUNCTIONING AS NEEDED. THE VEHICLE WAS TAKEN TO SIERRA BLANCA MOTOR CO. (304 US-70, RUIDOSO, NM 88345, (855) 707-6474) TO BE REPAIRED UNDER NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC). THE TECHNICIAN ALSO INSPECTED THE LIGHTS AND STATED IN THE DIAGNOSTIC REPORT THAT ALL LIGHTS WERE WORKING AT THE TIME OF INSPECTION. THE VEHICLE WAS TAKEN TO AN UNKNOWN DEALER FOR THE FAILURE HOWEVER, THE SECOND DEALER WAS UNABLE TO DUPLICATE THE FAILURE. THE CONTACT THEN HAD HER FRIEND, WHO WAS A RETIRED AUTHORIZED GMC TECHNICIAN, INSPECTED THE TAILLIGHTS AND DUPLICATED THE FAILURE. THE VEHICLE WAS THEN TAKEN BACK TO SIERRA BLANCA MOTOR CO. HOWEVER, THE SERVICE ADVISOR INSPECTED THE TAIL LIGHTS BUT OFFERED NO ASSISTANCE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THEY WOULD CHECK WITH THE DEALER TO SEE IF THEY COULD ASSIST WITH THE FAILURE. THE MANUFACTURER LATER INFORMED THE CONTACT THAT THEY WOULD OFFER A 25% DISCOUNT FOR EACH LIGHT TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 61,835.

STOP AND TAIL FUNCTIONS INSIDE THE TAIL LAMPS HAVE BECOME INOPERATIVE. PURCHASED VEHICLE USED AND FALLS JUST OUTSIDE OF THE SPECIAL COVERAGE ADJUSTMENT; N182180270. THIS IS STILL VERY MUCH A SAFETY ISSUE, EVEN THOUGH IT'S 1 MONTH LONGER THAN THE 6 YEAR CUTOFF.

NHTSA ODI 11413964

PURCHASED A 2015 YUKON DENALI BACK IN NOVEMBER 2019. SINCE PURCHASING THE VEHICLE WE HAVE HAD TO REPLACE THE BATTERY, TRANSMISSION, AC COMPRESSOR AND EXPANSION VALVE (WHICH STILL ISN'T WORKING CORRECTLY, BECAUSE IT DOESN'T BLOW COLD AIR), AND THE BLACK PANELS THAT ARE IN BETWEEN THE WINDOWS. ALSO, BOTH TAIL LIGHTS HAVE DECIDED TO QUIT WORKING.... WHICH CONCERNS ME GREATLY BECAUSE CARS BEHIND ME DON'T KNOW WHEN I AM STOPPED OR APPLYING THE BREAKS. STOPPED OR HAVE MY FOOT ON THE BREAK.

PASSENGER SIDE TAIL LIGHT/BRAKE LIGHT GOES OUT INTERMITTENTLY AT RANDOM. I PURCHASED CAR USED IN FEBRUARY 2020 AND WAS INFORMED SOON AFTER BY FRIEND THAT MY TAIL LIGHT WAS OUT WHEN LEAVING THEIR HOME. IT WAS WORKING THE NEXT DAY WHEN I CHECKED. I NOW WATCH IT AND SEE THAT IT WORKS ONLY SOMETIMES. COST TO REPLACE IS APPROXIMATELY $700 ASSUMING ONLY A REPLACEMENT LIGHT IS NEEDED AND NOTHING ELSE IS WRONG. BASED ON THE MULTIPLE COMPLAINTS I HAVE SEEN THIS SOUNDS LIKE A WIRING ISSUE THAT SHOULD BE A MANUFACTURER RECALL FOR SAFETY REASONS.

REAR BREAK LIGHT . INTERNAL WIRING OF THE TAIL LIGHTS CRACKS LEADING TO TAIL LIGHT FAILURE. THE FAILURE DOES NOT TRIGGER ANY WARNINGS AND THE DRIVER IS UNAWARE OF THIS FAILURE UNLESS THEY PREFORM A PRE TRIP INSPECTION.

BOTH REAR TAIL LIGHT ASSEMBLIES WENT BAD. THE LEFT ONE IN APRIL OF 2019 AND THE RIGHT ONE IN JANUARY OF 2021. SERVICE ADVISORS IN THE 2 DEALERSHIPS I DEAL WITH CLAIM THE DO NOT KNOW ANYTHING ABOUT IT. YET A NUMBER OF REPAIR SHOPS ON THE INTERNET KNOW OF THIS PROBLEM IN 2015 TO 2019 YUKON'S BECAUSE THEY REPAIR THEM. FUNNY THAT GM DOES NOT. I SENT THE 1ST ONE OUT AND IT WAS REPAIRED FOR WELL UNDER THE COST OF A NEW ONE. I COMPLAINED AGAIN TO THE SERVICE ADVISOR ABOUT THIS ONE TO NO AVAIL. GOING TO SEND IT OUT FOR REPAIR AS WELL. INCIDENTALLY THEY COVER THE REPAIR WITH A LIFETIME WARRANTY.

REAR LED TAIL LIGHTS FAILING. 1 HAS BEEN REPLACED ALREADY, SECOND, OPPOSITE SIDE IS NOW FAILING.

NHTSA ODI 11395460

BOTH REAR TAIL LIGHTS ARE INOPERABLE AND THE DEALER WANTS OVER $800 TO REPLACE. I'M OVER THE MILEAGE LIMIT FOR THE RECALL SO I'M OUT OF LUCK.

NHTSA ODI 11389850

PASSENGER REAR BRAKE LIGHT IS OUT. ALL LED LIGHTS WILL NOT LIGHT UP WITH RUNNING LIGHTS ON OR THE BRAKE DEPRESSED

NHTSA ODI 11389210

THE BACK PASSENGER BRAKE LIGHT HAS BEEN FUNCTIONING INTERMITTENTLY FOR THE PAST 15 MONTHS. WE HAVE BEEN STOPPED BY OTHER VEHICLES LETTING US KNOW 'YOUR TAILIGHT IS OUT' BUT WHEN WE GET HOME TO LOOK AT IT, THE LIGHT IS FUNCTIONING JUST FINE. AFTER MULTIPLE OCCURRENCES BEING TOLD THE SAME THING, WE TOOK THE YUKON INTO THE DEALER TO HAVE IT CHECKED. THE DEALER LET US KNOW THAT THIS IS A KNOWN ISSUE WITH THIS DESIGN, AND THAT THERE IS A RECALL/WARRANTY FOR THIS ISSUE. HOWEVER - OUR YUKON HAD 76,000 MILES AT THE TIME WE TOOK IT IN, AND THE RECALL ONLY COVERED VEHICLES LESS THAN 72,000 MILES OR 6YEARS FROM DATE OF SERVICE. NOW - I HAVE READ MANY FORUMS AND SEEN ALL ACROSS THE COUNTRY THAT THIS ISSUE IS OCCURRING DUE TO A POOR DESIGN FROM GM. LIMITING THE RECALL TO A CERTAIN MILEAGE IS [XXX] WHEN YOU KNOW THERE IS A DESIGN FLAW IN THE FIRST PLACE. NOT ONLY IS THIS A SAFETY CONCERN WITH THE TAILLIGHT NOT WORKING, BUT GM IS NOW REFUSING TO REPLACE IT? I EXPECT THIS ITEM TO BE COVERED IN FULL, AS I DON'T SPEND $70K ON A VEHICLE ONLY TO HAVE TO REPLACE DEFECTS ON MY OWN DIME. $1000 FOR A REPLACEMENT TAILLIGHT, ARE YOU KIDDING ME? I WOULD LIKE OUR TAILLIGHT REPLACED AT NO COST DUE TO POOR DESIGN AND A MANUFACTURER'S DEFECT - BOTH OF WHICH ARE NO FAULT OF THE USE AND OWNERSHIP OF MY YUKON. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

REAR BRAKE/TAILLIGHT ASSEMBLY NOT WORKING CONSISTENTLY IN MOTION.

NHTSA ODI 11364086

LEFT REAR LIGHT ASSEMBLY INTERMITTENT OPEN CIRCUIT. WIRING CHECKS OKAY. GOOD POWER AND GROUNDS. NOTED THAT THE LAMP HOUSING HAS EVIDENCE OF CORROSION AT THE BASE OF THE MAIN CONNECTOR. THE HOUSING IS A SEALED UNIT (NO SERVICEABLE PARTS) SO THE NATURE ASSEMBLY NEEDS TO BE REPLACED. I AM A 37+YEAR A.S.E. MASTER TECHNICIAN AND STATE OF MICHIGAN MASTER TECHNICIAN SO I AM WELL SEASONED AT PROPER AUTO/LIGHT TRUCK ELECTRICAL DIAGNOSIS. THE LIGHT WILL GO OUT WHILE SITING STILL AND/OR IN MOTION. THIS IS A SAFETY CONCERN FOR OBVIOUS REASONS.

DRIVER TAIL LIGHT WORKS INCONSISTENTLY

NHTSA ODI 11362143

PASSENGER REAR BRAKE LIGHTS QUIT WORKING. APPEARS TO BE A DEFECT IN THE DESIGN THAT CAUSES A BREAK IN THE CIRCUIT ON THE LIGHT ASSEMBLY. REPAIR CAN BE MANUALLY DOWN BY CUTTING THROUGH PLASTIC OF ASSEMBLY AND SOLDERING BREAK, OR REPLACEMENT OF ENTIRE LIGHT ASSEMBLY. NO ACCIDENTS - JUST NORMAL DRIVING.
