2015 GMC Yukon Denali XL

The contact owns a 2015 GMC Yukon XL Denali. The contact stated while driving approximately 30-35 MPH, the engine and oil warning lights illuminated, and the contact pulled over. There was no indication of oil leaking on the ground. The contact had her son-in-law, an independent mechanic to check the oil and it was determined that the oil level was low. The contact stated that oil was added; however, three days later the oil level was low again. The vehicle was taken to the local dealer and the contact was notified of an excessive oil consumption failure. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline for assistance. The warranty company declined to repair the vehicle. The failure mileage was approximately 85,000.

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.

THE PASSENGER SIDE TAILLIGHT STARTED 'GOING OUT' RIGHT AFTER THE WARRANTY EXPIRED-MEANING, IT WOULD WORK OFF AND ON AT VARIOUS TIMES. THEN THE DRIVERS SIDE TAILLIGHT HAS STARTED DOING THE SAME THING. THIS IS A KNOWN ISSUE WITH THE GMC TAILLIGHTS AND YET GMC HAS YET TO RECOGNIZE ANY ISSUE. THIS IS A MAJOR SAFETY ISSUE FOR ANYONE DRIVING THESE MODELS WITH FAILING TAILLIGHTS. THIS NEEDS TO BE INVESTIGATED

THE WHEELS HAVE CORROSION AND SHARP EDGES HAVE STARTED TO FORM. THESE SHARP EDGES ARE PUTTING PRESSURE ON THE THE TIRES CAUSING THEM TO LOSE AIR. WE WERE REQUIRED TO PURCHASE NEW WHEELS AS THE ONLY SOLUTION. WHEELS SHOULD LAST THE LIFE OF A VEHICLE, NOT FOUR YEARS.

MY YUKON MAKES VERY HARD SHIFTS WHEN ACCELERATING AND DECELERATING. THE TCM WAS REPROGRAMMED AFTER VEHICLE SHUT OFF ON THE HIGH WAY LAST NOVEMBER. NOW THE TRUCK SHUDDERS BETWEEN 25 AND 45MPH ESPECIALLY WHEN CLIMBING OR FILLED WITH PASSENGERS. VIBRATION CAN BE FELT THROUGH THE CABIN.

FAULTY BRAKE-LIGHT AND COSTLY FIX. DEALERSHIP HAS TAILLIGHT ON BACK ORDER SO A REPLACEMENT ISNT EVEN AVAILABLE. DEALERSHIP WANTS $675 JUST FOR THE PART THAT CANT EVEN BE ORDERED. DANGEROUS TO DRIVE THE VEHICLE WITH NO SOLUTION AVAILABLE.

TAIL LIGHTS INTERMITTENTLY GO OUT WITHOUT NOTICE. THIS CAN HAPPEN WHILE DRIVING OR STATIONARY

REAR PASSENGER BRAKE LIGHT WORKS INTERMITTANTLY WHILE DRIVING.

WE HAVE HAD BOTH OUR TAILLIGHTS FAIL. THE BLINKERS STILL FUNCTION BUT BECAUSE THEY ARE LED THEY SAY THEY MUST REPLACE THE WHOLE UNIT. EACH SIDE COST $672. THAT IS OUTRAGEOUS FOR A TAILLIGHT. THERE NEEDS TO BE A WAY TO REPLACE EACH PIECE.

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI XL. WHILE ATTEMPTING TO SHIFT THE VEHICLE FROM PARK INTO DRIVE, THE TRANSMISSION MADE A HARD CLUNKING SOUND. ALSO, WHILE DRIVING BETWEEN 30-50 MPH, THE VEHICLE VIBRATED ABNORMALLY. THE VEHICLE WAS TAKEN TO LEWIS CHEVROLET BUICK OF LIBERAL (LOCATED AT 202 N GRANT AVE, LIBERAL, KS 67901, (620) 624-2584) WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION FLUID NEEDED TO BE FLUSHED AND REFILLED. THE VEHICLE WAS SERVICED, BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS CONTACTED. THE FAILURE MILEAGE WAS UNKNOWN.

VEHICLE HAS UNDER 45,000 MILES AND BOTH HEADLIGHTS NEED TO BE REPLACED DUE TO MALFUNCTIONING LED'S FROM WATER INTRUSION. THIS HAPPENS AFTER WASHING MY CAR AND NOW IT WILL NOT PASS STATE INSPECTION DUE TO DRIVER SIDE DAYTIME LED NOT TURNING ON, AND PASSENGER SIDE DRL NOT TURNING OFF. I CAN NOT GET THIS FIXED BECAUSE THE PASSENGER SIDE LIGHT IS ON BACKORDER, YET MY LOCAL DEALER SAID THIS ISN'T A KNOWN PROBLEM. TAKE A LOOK ON THE INTERNET AND IT'S CLEARLY A MANUFACTURING ISSUE (HENCE BACKORDERED HEADLIGHTS)

BOTH REAR LIGHT ASSEMBLIES HAVE HAD ISSUES. DRIVERS SIDE WAS FIRST, BRAKE LIGHT STOPPED WORKING. REPLACED UNDER WARRANTY. PASSENGER SIDE BRAKE LIGHT AND PARKING LIGHT HAVE NOW STOPPED WORKING, JUST OUT OF WARRANTY. PROBLEM COMES AND GOES DEPENDING ON TEMPERATURE. I WOULD THINK THIS WOULD BE CONSIDERED A SAFETY ISSUE AND BE THE SUBJECT OF A RECALL SINCE IT IS WIDE SPREAD.

DRIVER'S SIDE, REAR TAIL LIGHT FAILED TO LIGHT WHEN PARKED, OR WHEN DEPRESSING THE BRAKE PEDAL. DEALERSHIP QUOTED JUST UNDER $800 TO REPLACE. HAD LIGHT REPLACED, AND THE SAME THING IS HAPPENING AGAIN. DEALER STATES THAT "LIGHTS GO OUT SOMETIMES."

AT 75,000 MILES I WOULDN'T EXPECT TO HAVE THIS MANY ISSUES OUT OF SUCH A NICE EXPENSIVE TRUCK... THE CHECK ENGINE LIGHTS COMES ON AND OFF AND IT PLEASES. WHEN THE CHECK ENGINE LIGHT IS ON THE REMOTE START DOESN'T WORK. THE TAIL LIGHTS WORK WHEN THEY WANT TO AND TO FIX A TAIL LIGHT JUST 1 IS $800.00. WHILE DRIVING ALL TYPES OF WARNINGS AND LIGHTS START COMING ON IN A RAPID WARNING ANNOYANCE. I'VE NEVER HOOKED A TRAILER TO THIS TRUCK AND IT KEEPS GIVING ME SOME TYPE OF TRAILER BRAKING SYSTEM WARNING. THE CRUISE CONTROL WORKS WHEN IT WANTS TO. BIG ISSUE!!!!! THE TRANSMISSION IS SLIPPING!!!!!!!!!!!! WHEN DRIVING IT WILL GIVE A HARD JERK AS IF IT'S HAVING TROUBLE SHIFTING. DOING THIS AT ANY SPEEDS, ANYTIME DURING ACCELERATING. SO MANY ISSUES OUT OF THIS TRUCK IT'S TO THE POINT WE ARE THROWING AWAY A TON OF MONEY ONTHIS THING!!!!!

BOTH REAR TAIL LIGHTS HAVE GONE OUT.

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!

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.

SUV SHUTTERING AND SHAKING WHILE IN MOTION ON CITY STREETS AND HIGHWAY

LED BRAKE LIGHTS FAILED IN BOTH TAIL LAMPS. LED IS SUPPOSED TO BE A LONGER LASTING ALTERNATIVE TO STANDARD LIGHTS. UNFORTUNATELY THE WAY GM DESIGNED THESE YOU CANNOT SERVICE OR REPAIR THEM LIKE YOU CAN WITH A TRADITIONAL BULB. AFTER MUCH RESEARCH IT APPEARS THAT THERE IS A THIN STRIP THAT BREAKS IN THE CIRCUIT CAUSING BOTH TAILLAMPS TO LOOSE FUNCTIONALITY, THERE IS NO BULB OUT WARNING SO THE DRIVER IS NOT ALERTED. AND WITH NO BRAKE LAMPS THIS COULD RESULT IN A CRASH OR INJURY.
