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

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.

Air conditioning stopped working.

I was dropping my daughter off at school in the car line. I was at low speed trying to brake and with the brake all the way down couldn't stop immediately. I was able to stop but then went to go again and when tried to stop again, couldn't and hit the car in front of me. It was making a sound while trying to brake but wouldn't engage my brakes. Luckily it didn't leave any damage and the other driver said it was OK and accepted my apology as my brakes were not working correctly.

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

Brakes are not stopping the vehicle on short distances as it should. They are doing a clicking kind of noise and can feel pulses in the brake pedal as though ABS are trying to activate. I know there is a recall out but is saying my 2015 is not listed yet is doing the same thing that is described in the recall.

NHTSA ODI 11431123

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.

Fuel injector is direct injection into cylinder. Excess carbon build-up is endemic with this design causing power loss/decrease, knocking, and potentially increased emissions. Safety factor is loss/decrease of engine power when needed for safe highway driving. This problem is noted in GM literature and technical bulletins. The Malfunction Indicator Light (MIL), also know as the Check Engine Light, illuminated and provided generic malfunction codes via the OBD. Cylinder #7 fuel injector removed and replaced, mechanic inspected the used injector. Heavy carbon build-up noted.

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.

NHTSA ODI 11426400

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!

LED brake light on drivers side fails to illuminate (noticed first at about 72,700 miles). Upon further research, this appears to be a recurring issue with 2015-2016 Yukon and Yukon XL vehicles. The LED taillight assembly is a sealed housing and the individual brake light bulbs are not replaceable. There appears to be a design defect that is causing premature failures of these assemblies, which results in a safety hazard because the driver does not receive any notification that the brake lights have failed.

The contact owns a 2015 GMC Yukon. The contact stated that while driving approximately 25 mph, the check engine warning light illuminated, and the vehicle started to vibrate abnormally. The contact had taken the vehicle to the dealer who diagnosed that the catalytic converter needed to be replaced. The vehicle had not been repaired. The manufacturer was not made aware of the issue. The approximate failure mileage was 120,058.

NHTSA ODI 11422251

At certain speeds my vehicle vibrates, like a grinding sound at speeds between 50-55. This is a safety risk because I have children and grandchild that frequently ride with me. I have taken my vehicle back to the dealership and they say it is no codes and send it back to me without fixing the problem. My vehicle has not been inspected by anyone except the GM dealership. I got my vehicle Nov. 2018 and this started happening between Dec. 2018 and Jan. 2019. My check engine light did appear and was flashing around this time. In 2019 I had to replace the rear shocks and I believe they are not working properly now.

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 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.

THE TAIL LIGHTS FLICKER AND SOMETIMES DON'T WORK AT ALL.

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.

NHTSA ODI 11413868

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.

NHTSA ODI 11408185

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.

NHTSA ODI 11406995

ISSUE WHEN BRAKING. LOTS OF FORCE NEEDED AT TIMES TO STOP.SEEMS TO OCCUR MORE AT SLOWER SPEEDS.

ONSTART NOT WORKING PROPERLY. CANNOT ACCESS GPS AND/OR CERTAIN FUNCTIONS IN THE GMC APPLICATION DUE TO NO ANTENNA SIGNAL BEING OBTAINED THROUGH INTELLILINK SYSTEM. ONSTAR MIRROR HAS A RED LIGHT AND GPS HAS A CROSS HATCH THROUGH IT. WE HAVE ACTIVATED ONSTAR PROFILE AND SUBSCRIPTION. I KNOW THEIR HAS BEEN A RECALL ON THIS ANTENNA IN THE PAST BUT WE JUST PURCHASED THE VEHICLE.

FIRST NOTE THAT OUR RECALL FOR INCREASED PEDAL EFFORT WAS DONE ON OUR 2015 GMC YUKON 2 MONTHS BEFORE THIS INCIDENT. OUR VEHICLE WAS TRAVELING AT A HIGH RATE OF SPEED COMING HOME FROM MAMMOTH ON THE 15 FREEWAY. WE HEARD WHAT WE DESCRIBE AS A 'BUZZING' NOISE BUT WE COULDN'T TELL IF IT WAS OUR CAR OR ANOTHER ON THE FREEWAY IT ALMOST SOUNDED LIKE TIRE TREAD BEFORE YOU HAVE A BLOW OUT. WE SLOWED DOWN A BIT (65-70MPH) TO CHECK OUR SURROUNDINGS. A FEW MINUTES LATER WE STARTED TO LOSE CONTROL OF OUR YUKON. I STARTED TO UNBUCKLE AND CLIMB TO MY HUSBANDS DRIVERS SEAT BECAUSE HE WASN'T RESPONDING TO OUR SCREAMS AND HE LOOKED ILL. AS I WAS SCREAMING HIS NAME HE FINALLY SAYS INTO MY EAR WE HAVE TO CRASH! I PANICKED AND SCREAMED WHAT IS HAPPENING. HE REPLIES 'WE HAVE NO BRAKES'! THE PEDAL WAS AS HARD AS A ROCK LIKE A BRICK WAS UNDERNEATH IT AND OUR CAR WAS SERVING BACK AND FORTH. AS TRAFFIC SLOWED AND WE PREPARED TO CRASH INTO THE CAR IN FRONT THE CENTER DIVIDER OPENED UP AND WE WERE ABLE TO CRUISE DOWN IT UNTIL WE SLAMMED E BRAKE ON. THESE MODELS SHOULD NOT BE ON THE ROAD AND WE COULD HAVE VERY EASILY DIED OR KILLED ANOTHER FAMILY IN THE PROCESS! ABSOLUTELY UNACCEPTABLE ON GMS PART! TERRIFYING! THERE HAS BEEN NO VACUUM PUMP RECALL PLACED ON OUR YUKON AND IT WAS THE VACUUM PUMP THAT FAILED WHICH MADE THE BRAKES FAIL THERE WAS NO BACK UP ZERO BRAKES WITH A FAMILY OF 5 IN THE CAR ON THE FREEWAY! EVERY OWNER WHO OWNS A 2015/2016 SHOULD BE AWARE THAT THIS CAN HAPPEN TO THEM. IT'S NOT JUST AT SLOW SPEED. WE HAVEN'T STEPPED FOOT IN OUR CAR SINCE OUR KIDS ARE SCARED TO DEATH TO RIDE IN ANY CAR THAT LOOKS LIKE IT.
