What 839 owners told NHTSA about the 2015 GMC Yukon Xl 1500

HEADLIGHTS AND BRAKE LIGHTS QUIT WORKING

NHTSA ODI 11191726

TURN SIGNAL FAILURE ON THE PASSENGER SIDE. CAUSE BY CONDENSATION IN THE HEADLAMP ASSEMBLY. COST $1300 TO REPLACE AND GET A NEW TURN SIGNAL. A TURN SIGNAL IS $5, BUT THEN INTEGRATED LEDS COST $1300 BECAUSE THEY HAVE TO REPLACE THE WHOLE ASSEMBLY.

BRAKE LIGHT IS NOT WORKING ON PASSENGER SIDE. WENT TO REPLACE BULB AND FOUND OUT THAT ONE HAS TO REPLACE THE ENTIRE TAILLIGHT ENSEMBLE WHICH IS $700-800. IT IS SAD THAT SOMETHING IMPORTANT TO SAFETY LIKE A BRAKE LIGHT HAS TO COST THAT MUCH TO REPLACE. I RESEARCHED AND FOUND THIS TENDS TO BE A COMMON PROBLEM. SO MUCH FOR LED LIGHTS--THIS IS ALSO POOR ENGINEERING!

TL* THE CONTACT OWNS A 2015 GMC YUKON. THE CONTACT STATED THAT THE LED TAIL LIGHTS BURNED OUT PREMATURELY. THE CONTACT CALLED [XXX] AT 817-264-7746 (LOCATED AT 501 TX-114, GRAPEVINE, TX 76051) AND WAS INFORMED THAT THE TAIL LIGHT WAS A SEALED UNIT THAT NEEDED TO BE REPLACED AS A WHOLE. THE CONTACT STATED THAT THE REPAIR WAS TOO COSTLY FOR A SIMPLE BURNED OUT BULB. THE CONTACT CALLED IT A DESIGN FLAW. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE, STATED THAT NOTHING COULD BE DONE, AND OFFERED THE CONTACT A SMALL DISCOUNT FOR AN OIL CHANGE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 66,000. THE VIN WAS NOT PROVIDED. *DT INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I WAS DRIVING UP NORTH IN 4WHEEL DRIVE AND TRANSMISSION CAM OUT OF GEAR I STOPPED THE VECHILE AND RESTARTED NOW THE TRANSMISSION DOES NOT SHIFT PROPERLY AND STEERING IS HARD TO STEER AND IT GOES IN AND OUT

POWER BREAKING FAILS WHEN DRIVING AT LOW SPEEDS, BRAKE PEDAL STIFF AND HARD TO PUSH DOWN TO STOP VEHICLE IN BOTH FORWARD AND REVERSE DIRECTIONS WHEN INCHING FORWARD AT A STOP LIGHT/SIGN, OR PARKING IN A PARKING LOT IN FORWARD AND REVERSE CAR KEEPS MOVING. STOPPING REQUIRED VERY HARD PUSH ON THE STIFF BRAKE PEDAL.. BRAKING AT HIGHER SPEEDS LESS AFFECTED BUT SUDDEN STOPS CAN REQUIRE MORE FORCE THAN USUAL AS THE CAR SLOWS DOWN. PROBLEM BEGAN DECEMBER 2017 RARELY AND INTERMITTENTLY, AND INCREASED TO ALL THE TIME BY FEBRUARY 2019 AT LOW SPEEDS THE POWER BRAKE DID NOT WORK AND REQUIRED MUCH FORCE ON THE BRAKE PEDAL TO STOP VEHICLE EVERY TIME. BRAKE FLUID WAS FINE AND SO WAS BRAKE PADS. GM DEALERSHIP VISIT SHOWED A FAILURE OF THE VACUUM PUMP FOR BRAKE LINE AND THEY INSTALLED A REDESIGNED PUMP WHICH SHOWS THAT THE ORIGINAL HAS FAULTY DESIGN. THEY ALSO REQUIRED A BELT THAT OPERATES PUMP TO BE REPLACED AS WELL. THIS SEEMS TO HAVE FIXED THE PROBLEM FOR NOW BUT THIS REPAIR HAS A TWO YEAR GUARANTEE. PRICE FOR ME TO FIX OVER $881+TAX.

BRAKE LIGHTS FOR PASSENGER REAR LAMP ASSEMBLY IS NOT WORKING. THIS IS THE SECOND TIME WITHIN 25 MONTHS THAT THIS HAS HAPPENED. THE ENTIRE LAMP ASSEMBLY NEEDS TO BE REPLACED AT A COST OF $600+. THE VEHICLE HAS LESS THAN 49,000 MILES, AND IT IS NO LONGER COVERED UNDER WARRANTY. ONLINE FORUMS INDICATE THAT THIS IS A COMMON PROBLEM WITH THE BRAKE LIGHTS IN THE LAMP ASSEMBLIES. IT APPEARS THE CIRCUIT BOARDS FOR THE LED BRAKE LIGHTS ARE BREAKING.

THE PASSENGER SIDE BRAKE LIGHT DOES NOT WORK. I REPLACED THE LIGHT ASSEMBLY AND IT STILL DOES NOT WORK. THE DEALERSHIP MECHANIC SAID IT COYLD BE TGE WIRING.

2015 GMC YUKON SLE. CONSUMER WRITES IN REGARDS TO PRESSURE BOOMING SENSATION WHILE DRIVING VEHICLE. *LD *TR

PASSENGER SIDE REAR BRAKE LIGHT WAS WORKING INTERMITTENTLY AND NOW HAS STOPPED WORKING ALL TOGETHER. THE BRAKE LIGHT UNIT IS A SEALED UNIT THAT CAN NOT BE SERVICED, IT MUST BE REPLACED ENTIRELY. VERY COMMON PROBLEM ON THIS MODEL DUE TO A FAULTY BRAKE LIGHT ASSEMBLY. FAILURE OF BRAKE LIGHTS PUTS THE SAFETY OF MY FAMILY IN JEOPARDY.

NHTSA ODI 11185596

TAIL AND BRAKE LIGHTS FAILED. UPON INSPECTION IT WAS FOUND THAT THE CONDUCTIVE PLATE BETWEEN THE LEDS HAD CRACKED/BROKEN IN BOTH ASSEMBLIES.

NHTSA ODI 11184992

ENGINE SHUTS OFF, STEERING ASSIST DISAPPEARS AND STEERING WHEEL IS JERKED OUT OF MY HAND, STABILITRAK WARNINGS ON DASH, HVAC SCREEN GOES BLANK, CHIMES START GOING OFF. THIS OCCURRED AS I WAS PULLING INTO A PARKING LOT AND I ALMOST HIT ANOTHER CAR. THE VEHICLE WAS MOVING AT NO MORE THAN 10MPH.

NHTSA ODI 11183932

I LOST BRAKES. EXTREME PRESSURE ON PEDDLE REQUIRED FOR BRAKES TO ENGAGE. EVEN THEN ONLY REDUCED BRAKING POWER WAS AVAILABLE. REQUIRED REPLACEMENT OF VACUUM PUMP AND BOOSTER. OCCURRED WHEN VEHICLE ENGINE WAS AT IDLE. OTHERWISE BRAKES FELT WEEK BUT AVAILABLE.

NHTSA ODI 11184180

THE BRAKE LIGHTS HAVE GONE OUT WITH ONLY 42000 MILES ON IT. I HAVE READ ON MESSAGE BOARDS ACROSS THE NATION THIS IS A MAJOR PROBLEM. DEALER WANTS 800 TO FIX IT.

NHTSA ODI 11182841

EXTERIOR LIGHTING ISSUES. REAR RUNNING LIGHTS NOT WORKING. REAR BREAK LIGHTS ARE NOT WORKING. RIGHT SIDE BLINKER NOT WORKING IN FRONT HEAD LAMP OR REAR LIGHTING FIXTURE. WHEN THE VEHICLE IS HOOKED TO THE COMPUTER AT A GM DEALERSHIP THE COMPUTER WILL NOT SHOW WHAT THE ISSUE IS. THIS IS A SAFETY ISSUE AS I CAN NOT SAFETY DRIVE THE VEHICLE AT NIGHT DUE TO NO LIGHTS IN THE REAR OF THE VEHICLE NOR DURING THE DAY WITHOUT BREAK LIGHTS.

NHTSA ODI 11181797

LEFT BRAKE LIGHT WORKING INTERMITTENTLY AND THEN WENT OUT COMPLETELY. RIGHT BRAKE LIGHT FOLLOWED IMMEDIATELY AFTER. DEALER WANTS 1550.00 TO REPLACE

NHTSA ODI 11181340

BRAKE PEDAL IS STIFF AT LOW SPEEDS. THE PEDAL LOCKS UP AND STOPPING IS DELAYED 2 TO 3 FEET. IT MAKES OPERATING THE VEHICLE UNSAFE. I HAVE DONE RESEARCH ON THIS ISSUE. OTHERS ARE EXPERIENCING THE SAME DANGEROUS DELAYED STOPPING DISTANCE AND STIFF BRAKE PEDAL AT LOW SPEEDS.

BRAKING BECOMES "HARD" AFTER BRAKING WHILE MOVING (E.G. IN RUSH HOUR TRAFFIC OR SLOWLY GOING DOWN A HILL).THIS STARTED WHILE GOING DOWNHILL IN AN ANIMAL RESERVE. I WAS INCHING FORWARD TO GET BETTER VIEWS OF THE ANIMALS. HALFWAY DOWN THE HILL THE BRAKES COMPLETELY FAILED. I HAD TO LITERALLY STAND UP ON THE BRAKE, AND IT STILL WOULDN'T STOP THE CAR. AFTER TAKING MY FOOT OFF THE BRAKE FOR A BIT, THE PROBLEM FIXED ITSELF. WHEN I TOOK IT TO THE DEALER, THEY SAID IT WAS A FAULTY VACUUM PUMP ($500 REPAIR), BUT ONLINE RESEARCH SAYS REPLACING THE VACUUM PUMP DOESN'T SOLVE THE PROBLEM. NOTE, THIS PROBLEM CONTINUES TO PERSIST.

NHTSA ODI 11180836

ALL LED LIGHTS HAVE WENT OUT ON RIGHT SIDE, AS WELL AS BREAK LIGHTS. THIS IS A KNOW ISSUE TO GMC, AND YET THEY WILL NOT CORRECT IT. MY QUOTE TO HAVE IT FIXED WAS 2493.00 FROM LOCAL DEALERSHIP. THAT IS CRAZY. LED LIGHTS SHOULD LAST A WHOLE LOT LONGER THAN THIS. ALSO CONDENSATION IS IN THE FRONT HEADLIGHT WITH NO HOLES OR CRACKS. IF THIS HAPPENS WITH HOUSE WINDOWS, THEY ARE REPLACED BY THE MANUFACTURER. THERE ARE SO MANY COMPLAINTS, I WILL ALSO BE CONTACTING THE BETTER BUSINESS BUREAU. GMC KNOWS THERE IS A PROBLEM WITH THESE MODELS.

NHTSA ODI 11180890

MY REAR TAIL LIGHT WENT OUT 1 MONTH AFTER WARRANTY ENDED. THIS HAPPENS TO ALL MANY AUTOS IN THIS CLASS. PLEASE DO SOMETHING OR I WILL STOP BUYING GMC AUTOS.

NHTSA ODI 11180416

MY PASSENGER BRAKE LIGHT INTERMITTENTLY DOES NOT WORK. THIS IS CLEARLY A COMMON PROBLEM WITH THIS MAKE AND MODEL. HERE IS AN EXAMPLE OF ONE OF MANY FORUMS : HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963 THIS IS A SAFETY PROBLEM AND GMC SHOULD OFFER A RECALL FOR THEIR FAULTY LED LIGHTS.

NHTSA ODI 11175051

TAILLIGHTS WORKS INCONSISTENT NO BRAKE LIGHTS TOOK TO DEALER THEY SAID THE BOTH LIGHTS NEED TO BE REPLACED AND MY WARRANTY DOESN'T COVER IT THEY SAID THESE VEHICLES ARE KNOWN FOR HAVING THIS PROBLEM NEED FOR HELP WITH THIS

NHTSA ODI 11174871

THIS IS THE SECOND COMPLAINT THAT I HAVE MADE TO NHTSA. THE FIRST TIME, THE VEHICLE WAS SPONTANEOUSLY TURNING OFF AND SHUTTING DOWN DURING BACKING IN AND TURNS CAUSING A SAFETY ISSUE. THIS RESULTED IN A RECALL, AND A "SOFTWARE UPDATE" THAT WAS DONE TWICE TO CORRECT THE ISSUE. RIGHT AND BACK PASSENGER LIGHTS BEGAN TO BLINK ON AND OFF AND WATER GETS INTO THE BRAKE LIGHT. THE DEALER TOLD ME THIS WAS M ISSUE. THIS TIME THE 4WD SERVICE LIGHT CAME AND THE CAR APPEARED TO BE STUCK IN "4WD LOW" MAKING IT "DRAG" AT A REDUCED SPEED WHEN DRIVING. ALSO, THE "SERVICE TRAILER BRAKE" LIGHT CAME ON REPEATEDLY. I HAVE NEVER USED THE TRAILER BRAKE. I TOOK IT INTO AN AUTHORIZED DEALER, SELLERS GMC IN FARMINGTON HILLS, MI. THEY TOLD ME I NEEDED A NEW "MODULE", SO I PAID TO HAVE THAT DONE. WITHIN ONE DAY THE SAME SERVICE LIGHTS CAME ON AGAIN. "SERVICE 4 WD" AND "SERVICE TRAILER BRAKE." I IMMEDIATELY TOOK THE VEHICLE BACK AND AM NOW BEING TOLD IT NEEDS ANOTHER SOFTWARE UPDATE AND A NEW TRAILER BRAKE TRANSFER SWITCH. QUITE FRANKLY, I BELIEVE THAT THIS MODEL HAS SIGNIFICANT, UNADDRESSED COMPUTER SOFTWARE ISSUES AND THE DEALER DOES NOT KNOW WHO TO FIX IT. THE CAR IS UNSAFE BECAUSE IT SPONTANEOUSLY STOPS WORKING APPROPRIATELY DURING DRIVING. THE CONCERNS HAVE BEEN VARIOUS AND ALWAYS SEEM TO AFFECT STEERING, WHEN TURNING OR BACKING IN. I AM BEING CHARGED FOR VARIOUS CONTROL PANELS AND MODULES. I AM REQUESTING THAT THIS CONCERN GETS ADDRESSED BEFORE THERE IS A SERIOUS INJURY. I WOULD LIKE MY VEHICLE FIXED AND RETURNED TO A SAFE CONDITION. I WAS NEVER TOLD UPON PURCHASE, THAT THIS MODEL WOULD REQUIRE SO MANY "SOFTWARE" UPDATES TO REMAIN SAFE. THIS SHOULD NOT BE A BURDEN PLACED ON A CONSUMER FOR A VEHICLE TO OPERATE SAFELY. THIS IS DANGEROUS.

FROM TIME TO TIME BRAKE PEDAL BECOMES HARD WHEN BACKING UP OR GOING FORWARD MAKING THE VEHICLE HARD TO COME INTO A COMPLETE STOP.
