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

ABOUT A MONTH AGO, I BEGAN TO RECEIVE AN ALERT THAT MY SIDE DETECTION SYSTEM NEEDED TO BE SERVICED. UPON INSPECTION, MY RIGHT SIDE MODULE HAD TO BE REPLACED. AFTER COMPLETING THE REPAIR, THE NEW MODULE WOULD NOT COMMUNICATE WITH THE LEFT MODULE WHICH IS HOW THE RIGHT MODULE GETS PROGRAMMED. IT WAS DISCOVERED THAT EVEN THOUGH THERE WAS NO ALERT THAT THE LEFT MODULE NEEDED TO BE REPLACED AS WELL. THIS IS A HUGE CONCERN THAT THESE MODULES WOULD FAIL THIS SOON INTO THE VEHICLE'S LIFE (68,000 MILES). THERE ARE NO MOVING PARTS, ETC. NOT TO MENTION THE SAFETY ISSUES OF NOT HAVING A WORKING SIDE COLLISION ALERT SYSTEM.

AFTER DRIVING A 100 MILE ROUND TRIP ON A US HWY, COUNTY ROADS, AND CITY STREETS, WE ARRIVED BACK HOME AND BEFORE WE COULD TURN OUR 2015 GMC YUKON XL, WE IMMEDIATELY BEGAN TO SMELL GASOLINE. DIRECTLY UNDERNEATH WHERE OUR 8 MONTH CHILD WAS JUST SITING, IS WHERE WE NOTICED 87 OCTANE FUEL DRIPPING RAPIDLY. AS I WAS LOOKING, MY WIFE WAS REMOVING OUR CHILD OUT THE PASSENGER SIDE WHERE SHE WAS SITTING. WE HAD SO MUCH GAS ON THE GROUND AND THE FUMES WHERE SO STRONG. I CAN NOT STRESS ENOUGH HOW QUICKLY THE FUMES ENGULFED OUR WHOLE VEHICLE, WITH ALL OF US STILL IN THE VEHICLE. HAD THERE BEEN A SPARK OF ANY KIND, IT WOULD HAVE BEEN ENOUGH TO CATCH OUR VEHICLE ON FIRE WITH US POSSIBLE STILL IN THE VEHICLE AND MAINLY OUR INFANT STILL IN THE VEHICLE. WE HAD THE VEHICLE BROUGHT TO A LOCAL REPAIR SHOP AND HAD TO HAVE OUR FUEL FEED LINE (ACDELCO PART# 84200274) REPLACED. THE ENGINEERS FOR GM, STUPIDLY HAD THIS FUEL LINE RUNNING THROUGH A MOLDED CLIP, THAT IS PART OF THE FUEL TANK, AND THE HOSE WAS 'SNAPPED' INTO IT TIGHTLY. THIS CAUSED ENOUGH FRICTION IN THE LINE MOVING BACK AND FORTH TO FINELY PLACE A HOLE IN THE FUEL LINE. NHTSA MUST TAKE THIS REPORT SERIOUSLY BEFORE IT COST THE LIFE OF SOMEONE THAT DOES NOT DESERVE BURNING ALIVE IN A VEHICLE. ISSUE THE RECALL IMMEDIATELY BEFORE THIS HAPPENS! MOST PEOPLE CAN NOT AFFORD A $350-$1,000 FIX OR MUCH LESS THE VALUE OF SOMEONE'S LIFE!

THE REAR TAIL LIGHT LED HAS MALFUNCTIONED AND WILL NOT WORK OR WORKS INTERMITTENTLY.

NHTSA ODI 11317186

NO BRAKE LIGHT IN BOTH REAR LIGHTING ASSEMBLIES. STARTED WITH THE PASSENGER SIDE AND NOW THE DRIVERS SIDE. GMC ISSUED A LETTER IN DECEMBER 2019 STATING THEY'D PAY FOR REPAIRS IF VEHICLE IS LESS THAN 6 YEARS OR 75,000 MILES WHICH EVER COMES FIRST. WE'LL I'M OVER ON BOTH. GMPP EXTENDED WARRANTY DOESN'T COVER THIS REPAIR. SPEND $75K FOR THIS TRUCK AND NOW THIS.

BOTH TAIL LIGHTS STOPPED WORKING ON THE FREEWAY DURING MY TRIP TO SAN DIEGO FROM PHOENIX. ABOUT HALFWAY HERE ONE TAIL LIGHT WENT OUT IN ABOUT 20 MILES LATER THE OTHER ONE STOPPED WORKING. I KNOW THIS BECAUSE A FRIEND WAS FOLLOWING ME.I CALLED THE DEALERSHIP, HE STATED THAT THE TAIL LIGHTS ARE ON NATIONAL BACKORDER AND WON'T BE IN FOR A WEEK PLUS. NOW I AM DRIVING AROUND CALIFORNIA WITH NO BRAKE LIGHTS.. I ONLY HAVE 48,000 MILES ON THIS SUV, EACH TAIL LIGHT IS $760 THE ONLY WAY TO REPAIR THIS IS TO REPLACE THEM. THANK YOU GM I WILL BE FORWARDING YOU MY TICKET..

FIRST, PASSENGER SIDE TAIL LIGHT WAS GOING ON AND OFF. SOMETIMES THE WHOLE PANEL WOULD NOT TURN ON. THEN, A FEW WEEKS LATER THE OTHER TAIL LIGHT STARTED DOING THE SAME THING AND NOW BOTH BRAKE LIGHTS DO NOT COME ON. THEY WILL SPORADICALLY START WORKING AGAIN EVER SO OFTEN.

GMC RECENTLY ADVISED US THAT THE TAILGATE LIGHTS HAVE HAD PROBLEMS WHERE THEY "INTERMITTENTLY" DO NOT ILLUMINATE. WE HAVE HAD THIS ISSUE FOR QUITE SOMETIME WHERE DRIVERS CANNOT SEE OUR TAILGATE LIGHTS WHEN THE PROBLEM OCCURS. BECAUSE IT HAS BEEN INTERMITTENT, IT HAS BEEN VERY HARD FOR THE SHOP TO DIAGNOSE AS WHEN THEY GET IT AND IT IS ON, THEY CAN'T FIGURE OUT WHAT IS WRONG WITH IT. SINCE WE RECEIVED THE LETTER FROM GMC, WE HAVE BEEN INTO THE DEALERSHIP TO GET IT RESOLVED, BUT THEY WILL NOT DO IT BECAUSE OUR MILES ARE OVER. I HAVE TOLD THEM THAT THEY KNOW ITS AN ISSUE AND THAT IT IS INTERMITTENT AND WHEN PEOPLE TAKE IT INTO THE SHOP TO GET IT DIAGNOSE, ITS A HIT AND MISS. I HAVE NOW SEEN OVER A DOZEN OTHER GMC'S ON THE ROAD WITH THE SAME ISSUE. LAST WEEK, WHILE TRAVELING WITH KIDS TO A SOCCER TOURNAMENT, BOTH WEREN'T WORKING AT NIGHT AND WE WERE PULLED OVER. I FORTUNATELY HAD THE LETTER IN THE CAR AND SHOWED IT TO HIM. HE GAVE ME A WARNING AND ADVISED THAT IT IS VERY DIFFICULT FOR CARS TO SEE AT NIGHT WHEN THERE ARE NO TAILGATES ON AND THAT GMC HAD BETTER GET THIS RESOLVED. I HAVE MADE TWO REQUESTS WITH GMC AND THEY HAVE DENIED THE REQUEST. I EVEN TOLD THEM THAT I WOULD COST SHARE IF WE MEET IN THE MIDDLE AND THEY WOULD NOT. THEY KNOW THIS IS AN ISSUE, YET THEY AREN'T WILLING TO EXTEND THE WARRANTY OR MAKE IT A RECALL. THIS IS VERY DANGEROUS AND COULD CAUSE A LOT OF ACCIDENTS WITH GMC MODELS NATIONWIDE. I HOPE THAT THIS IS BROUGHT TO SOMEONE'S ATTENTION AND THAT GMC IS ENCOURAGED TO GET THIS RESOLVED WITH 2015 YUKON XL SUVS AND THAT WE AND MANY OTHERS ARE ABLE TO GET THEIR TAILGATES REPLACED.

2015 GMC YUKON. CONSUMER WRITES IN REGARDS TO YUKON TAIL LIGHTS SAFETY RECALL. *LD *JS

THE RIGHT REAR BRAKE LIGHT LED STRIP NO LONGER WORKS. I HAVE NOTICED THAT THIS IS AN ON-GOING ISSUE WITH OTHER CONSUMERS. THE DEALER WANTS $650-$750 TO REPLACE. MOST OF THE TIME, IT IS A WIRING ISSUE THAT NEEDS TO BE REPAIRED. UNFORTUNATELY, THE PLASTICS ARE GLUED TOGETHER PREVENTING ACCESS TO MAKE THE REPAIR.

NHTSA ODI 11311589

I HAVE JUST REALIZED THAT ONE OF THE BACK SEAT PASSENGER SEAT BELT (THE ONE AT THE BACK OF THE DRIVER SEAT) HAS A DELAY TO GET ACTIVATED WHEN THE VEHICLE IS STOPPED DUE TO AN EMERGENCY, AND IN SOME CAS S IT DOES NOT GET ACTIVATED AT ALL.

NHTSA ODI 11311152

THE REAR PASSENGER BRAKE LIGHTS JUST RANDOMLY STOPPED WORKING. NOT A BULB ISSUE AS IT IS AN LED PANEL OF LIGHTS. THE BACK UP BULB STILL WORKS, BUT THE BRAKE LIGHTS DON'T. DEALER SAYS IT HAPPENS A LOT TO THESE CARS, AND HAVE TO BUY A WHOLE NEW UNIT. THIS IS A SAFETY ISSUE - BREAK LIGHTS FAILING DUE TO POOR WIRING. AGAIN NOT A REPLACEABLE BULB ISSUE, IT IS DUE TO A WIRING ISSUE WITHIN THE LIGHTING UNIT ITSELF

INTERMITTENT POWER STEERING FAILURE TURNING AT LOW SPEEDS. ALMOST HIT A CAR WHILE TURNING IN A ROAD DUE TO LACK OF POWER STEERING WORKING PROPERLY.

I PURCHASED MY VEHICLE OCTOBER 31'ST 2019 FROM A LOCAL DEALERSHIP. THE MILAGE WAS ABOUT 74K MILES. I HAVE ONLY HAD THIS VEHICLE FOR A FEW MONTHS. MY CONCERN IS THE FOLLOWING. WHILE DRIVING, AT LEAST 7 TO TEN TIMES THE VEHICLE COMPLETELY STALLS. IN OTHER WORDS IT COMPLETELY STOPS. THE STEERING WHEEL LOCKS. ALL POWER IS LOST. NO LIGHTS NO NOTHING. THIS HAS HAPPENED AT INTERSECTIONS, IT HAS HAPPENED WHEN TURNING LEFT, IT HAS HAPPENED WHEN TURNING RIGHT. IT HAPPENS WHEN WE ARE YIELDING. SOMETIMES THE DASH STARTS TO FLICKER AND ALSO THE CONSOLE. SOMETIMES LIKE TODAY WITHOUT ANY WARNINGS. THIS IS PUTS ME AND MY FAMILY IN A VERY DANGEROUS SITUATION. PLEASE RESPOND ASAP. I CURRENTLY HAVE 86K MILES ON MY VEHICLE.

REAR TAIL LAMPS ONLY WORK EVERY NOW AND THEN. HAPPENS WHILE MOVING AND STATIONARY. THE REAR TAIL LAMPS ARE CHEAPLY MADE INTERNALLY THAT THE CIRCUIT BOARD FOR THE LED LIGHTS EASILY BREAKS WITH REGULAR DRIVING. ITS AND OBVIOUSLY KNOW ISSUE FOR GMC BECAUSE THERE ARE BUSINESSES ONLINE THAT THERE SOLE INCOME IS TO REPAIR THESE TAIL LIGHTS ON 2015 TO CURRENT YUKON/ YUKON XL MODELS. TAKEN MY 2015 YUKON IN BEFORE WARRANTY WAS OUT AND GMC DEALER DOESN'T WANT TO WARRANTY AND DOESN'T WANT TO REPAIR. TELLS OWNERS THEY'LL HAVE TO BUY A NEW TAIL LAMP AT $800 A PIECE. TOTAL RIP OFF .

BRAKE LIGHTS WILL INTERMITTENTLY STOP WORKING. NO CONSISTENCY TO WHEN THEY STOP WORKING OR WHEN THEY START AGAIN. MAJOR SAFTEY HAZARD. GMC KNOWS ABOUT THE PROBLEM BUT ARE CALLING IT AN EXTENDED WARRANTY ISSUE, AND NOT FIXING VEHICLES OUTSIDE THEIR DESIGNATED TIME/MILEAGE BECAUSE THEY SAY IT IS NOT A SAFETY HAZARD...' IT IS!!!

THE YUKON'S AUTOMATIC TRANSMISSION CAN GET VERY JERKY WHEN ACCELERATING FROM A STOP, ESPECIALLY WHEN THE ENGINE IS COLD (FIRST 10-15 MINS OF DRIVING). CITY DRIVING SEEMS TO BE THE MAIN ENVIRONMENT WHEN THE TRANSMISSION JERKINESS OCCURS. THE JERKINESS STARTED SUBTLY AROUND 75,000 MILES, AND NOW AT ALMOST 100K MILES, THE ISSUE HAS ONLY GOTTEN MORE SEVERE. ACCELERATING FROM A STOP UPHILL AND AROUND TURNS ARE TIMES WHEN IT'S MORE PRONE TO JERK. THE BEST WAY I CAN DESCRIBE IT WOULD BE A LAG IN GEAR SHIFTING CAUSED BY SOME TYPE OF DELAY THE CAR'S ELECTRONIC CONTROL SYSTEM. THE LAG HAS OCCURRED SO VIOLENTLY AT TIMES, IT FEELS LIKE I'VE BEEN IN A REAR-END COLLISION. I WOULD HESITATE TO ALLOW BABIES TO RIDE IN THIS CAR DUE TO THEIR INABILITY TO BRACE WHEN THESE JERKS OCCUR; THERE'S DEFINITELY ENOUGH FORCE TO CAUSE WHIPLASH TO A BABY. I WOULD SAY THE JERK HAPPENS 2-3 TIMES EVERY TRIP, EVEN IF I SLOWLY ACCELERATE TO PREVENT QUICK GEAR SHIFTS FROM HAPPENING.
