2015 GMC YUKON DENALI XL Complaints

REAR LEFT TAIL LIGHT AND BRAKE LIGHT WORK INTERMITTENTLY. YET STARTED HAPPENING AND CAR WILL NOT PASS INSPECTION IN THE STATE OF VA. WHEN NOTICED THE VEHICLE WAS PARKED, BUT HAVE ALSO SEEN WHILE DRIVING.

TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI XL. THE CONTACT STATED THAT THE VEHICLE EMITTED AN ABNORMAL FUEL ODOR. UPON INSPECTION, THE CONTACT OBSERVED A PUDDLE OF FUEL ON THE GROUND. THE CONTACT ALSO NOTICED THAT THE FUEL TANK AND FUEL LINE DID NOT HAVE ENOUGH SPACE IN BETWEEN THEM, WHICH CAUSED A HOLE TO DEVELOP IN THE FUEL LINE. THE DEALER AND MANUFACTURER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 68,000. **TR CONSUMER STATED FUEL WAS LEAKING FROM PRESSURE LINE TO ENGINE ABOVE FUEL TANK. WHEN TANK WAS REMOVED THE FUEL LINE HAD RUBBED A HOLE IN ITSELF FROM THE WHERE IT CLIPS INTO THE TANK. THE LINE HAD PUSHED OUT ALMOST 2 GALLON OF FUEL IN LESS THEN 10 MINUTES OF IDLING TIME IN MY GARAGE. UPDATE 11/1/18*JB

RIGHT SIDE LED BRAKE LIGHTS ARE NOT WORKING. IT IS A KNOWN PROBLEM WITH THE ELECTRICAL TRACES IN SIDE THE SEALED LIGHT. REPLACEMENT IS $600!

THE REAR LED BRAKE TAIL LIGHT STOPPED WORKING DUE TO A CRACK IN THE CONDUCTIVE PLATE INSIDE THE ASSEMBLY.

A/C IN AUTOMOBILE STOPPED WORKING. THERE ARE ALLEGEDLY TWO DEFECTIVE PARTS IN THIS VEHICLE. THE DISCHARGE LINE AND THE CONDENSER. BOTH ARE TOO WEAK TO HANDLE THE PRESSURE FROM THE COOLANT

TAIL LIGHT NO LONGER WORKING. SAFETY HAZARD. IT STARTED FLASHING INTERMITTENTLY AND SMELLING FUNNY NOW IT WON'T WORK AT ALL. THIS WILL CAUSE AN ACCIDENT AND OF COURSE IT'S NOT UNDER WARRANTY AS I'M AT 60K BUT GMC WILL DO NOTHING FOR IT EVEN THOUGH THIS IS A WIDELY KNOWN ISSUE. I CONTACTED THEM AND THEY WILL DO NOTHING!

SUNROOF: WHILE TRAVELING ON THE ROAD AT 55MPH, MY SUNROOF, WHICH WAS CLOSED, RANDOMLY EXPLODED. YOU CAN SEE THE GLASS ACTUALLY PUSHED UP AND OUT WHEN IT BLEW. WE HAD GLASS EVERYWHERE IN THE VEHICLE. THERE WERE NO OTHER VEHICLES AROUND ME AND THERE WAS NOTHING THAT CAME THROUGH THE WINDOW. IT WAS A NICE SUNNY DAY, NO RAIN OR OTHER REASON FOR THIS TO HAVE HAPPENED. I STOPPED RIGHT AWAY AND TOOK PHOTOS OF THE DAMAGE. I CALLED MY INSURANCE COMPANY RIGHT AWAY AND AM WAITING FOR THE SUNROOF TO BE REPLACED.

TAILIGHT BRAKE LIGHT NOT WORKING, NO REPLACEMENT BULB AVAILABLE, GM SAYS MUST BE ENTIRE UNIT AND HOUSING FOR $701. THIS IS RIDICULOUS AND ONEROUS. THIS IS CLEARLY A DEFECTIVE DESIGN AND DEFECTIVE PART. SHOULD BE REPLACED OR REPAIRED FOR FREE.

AFTER ABOUT 1 YEAR OF OWNING THIS VERY EXPENSIVE VEHICLE (BOUGHT IT WHEN IT WAS ABOUT 2 YEARS OLD, IE. 2017) USED FROM A GMC DEALER - THE DRIVERS SIDE TAIL LIGHT STARTED WORKING ONLY INTERMITTENTLY AND THEN STOP WORKING ALL TOGETHER. I HAD THE DEALER ESTIMATE THE REPLACEMENT COST AND THEY TOLD ME IT WOULD BE $1,500 TO REPLACE BOTH TAIL LIGHTS (SAID I NEEDED TO REPLACE THE ENTIRE ASSEMBLY BECAUSE THEY WERE LED????). THIS IS ABSURD ON SO MANY LEVELS...THESE ARE ONE OF THE MOST EXPENSIVE VEHICLES ON THE MARKET AND WITHIN ONLY A FEW YEARS THE TAIL LIGHTS NEED TO REPLACED...AT AN OUTRAGEOUS COST. MY LAST YUKON (2007) DIDN'T HAVE A TAIL LIGHT GO OUT FOR MANY YEARS...AND I BOUGHT A REPLACEMENT BULB FOR $3 AND DID IT MYSELF. AFTER DOING SOME RESEARCH, IT APPEARS TO BE A "COMMON" ISSUE FOR THESE GMC VEHICLES...AND THE FACT THAT GMC IS WELL AWARE OF THIS IS DOING NOTHING ABOUT A KNOWN AND PERSISTENT ISSUE IS FRUSTRATING.

TAKATA RECALL WAS PULLED OVER BECAUSE MY PASSENGER TAIL LIGHT WAS NOT WORKING. TAIL LIGHT WAS WORKING THE NEXT DAY, AND THE FOLLOWING DAY IT HAD GONE OUT AGAIN. LIGHT WOULD COME BACK ON WHEN YOU HIT IT BY HAND.
