2015 GMC YUKON XL Complaints

THE AIR IN OUR 2015 YUKON HAS WENT OUT AND IS CONSTANTLY BLOWING WARM AIR. ITWILL NOT HOLD FREON. THE TEMPS IN LAS VEGAS GET INTO THE TRIPLE DIGITS. MY 78 YEAR MOTHER CONSTANTLY USES THE VEHICLE TO GET PLACES. I HAVE RESEARCHED THE PROBLEM AND SEEMS TO BE A CONSTANT PROBLEM WITH THE DESIGN OF THE AC CONDENSER AND HOSE DESIGN. WE HAVE BEEN SMELLING FREON FOR SOME TIME SO IT MUST HAVE BEEN SLOWLY LEAKING OUT. THIS SHOULD BE A RECALL PROBLEM SINCE SO MANY PEOPLE HAVE HAD THE SAME PROBLEM AND IS DEFINITELY A SAFETY PROBLEM HERE IN DESERT. THE PROBLEM IS CONSTANT, IN MOTION OR SITTING STILL.

REAR LED TAIL LIGHTS FAILING. 1 HAS BEEN REPLACED ALREADY, SECOND, OPPOSITE SIDE IS NOW FAILING.

MY 2015 YUKON XL SLT TRANSMISSION DEVELOPED A STUTTER WHILE GOING ALONG ACCELERATING BUT WOULD GO AWAY AS YOU DRIVE. UNFORTUNATELY THIS CAME TO AN ABRUPT END THIS PAST JANUARY WHEN I JUMPED IN IT AND WENT ABOUT 50 FEET AND THE VEHICLE SOUNDED LIKE IT WAS IN NEUTRAL AND I COULDN'T GO ANYWHERE WITHOUT CUTTING IT OFF AND STARTING OVER WHICH ONLY CAUSED THE PROCESS TO REPEAT.. I HAD MY MECHANIC TOW IT TO THEIR SHOP AND DIAGNOSE THE PROBLEM. THE TOLD ME THE TRANSMISSION WAS MALFUNCTIONING. I HAD A SECOND OPINION FROM THE DEALERSHIP I BOUGHT IT FROM AND THE CONCLUSION WAS THE SAME. THE VEHICLE HAD 162K ON IT AND I WAS EXPECTING IT TO MATCH WHAT MY PREVIOUS YUKON REACHED AND WAS STILL GOING. OVER $4K LATER WITH NEW TRANSMISSION, I'M KEEPING MY FINGERS CROSSED. THIS SHOULDN'T HAVE HAPPENED THIS SOON.

PASSENGER REAR BRAKE LIGHT IS OUT. ALL LED LIGHTS WILL NOT LIGHT UP WITH RUNNING LIGHTS ON OR THE BRAKE DEPRESSED

REAR LIFTGATE WILL NOT OPEN. REPLACED LIFTGATE CONTROL MODULE AND STILL WILL NOT WORK. MECHANIC SAYS IT IS NOW BODY CONTROL MODULE. LIGHTS STAY ON INSIDE VEHICLE AT ALL TIMES AND HORN IS DISABLED

THE BRAKES FAILED IN MY CAR CAUSING A REAR COLLISION WITH AN OBJECT IN MY DRIVEWAY. AFTER INSPECTION FROM A CERTIFIED GMC DEALERSHIP, THE BRAKE FAILURE WAS NOT CAUSED BY SERVICE NEGLECT OR AGE OF BRAKES, IT WAS DUE TO THE VACCUM PUMP FAILURE TO PROVIDE PRESSURE. THIS IS THE SECOND TIME IN TWO YEARS THIS PART HAS CAUSED MY BRAKES TO FAIL. THE DEALERSHIP REPLACED THE PART AT NO COST THOUGH THERE IS NOT FORMAL RECALL ON THIS PART. BOTH TIMES THIS PART FAILED THE CAR WAS IN MOTION. THE FIRST TIME IT WAS TOWED OUT OF A CITY TO BE REPAIRED AS IT WAS DANGERSOUS TO DRIVE AND THE SECOND TIME THE FAILURE CAUSED THE VEHICLE TO COLLIDE WITH A LARGE DUMPSTER IN MY DRIVEWAY CAUSING EXTENSIVE DAMAGE TO THE REAR PASSENGER SIDE OF THE CAR. THANKFULLY THERE WAS NOT PHYSICAL DAMAGE TO ANY PERSONS IN EITHER OF THESE TWO INCIDENTS WHICH BOTH WERE NO FAULT OF THE DRIVER OR OWNER OF THE CAR.

WHILE DRIVING ON HIGHWAY INSTITUTE STEERING POWER AND COULD BARELY CONTROL THE STEERING WHEEL WHILE POWER ASSIST WARNING, STABILIZE,AIRBAG LIGHT AND PASSENGER WINDOWS WOULDN'T GO UP.

THE BRAKES ON MY 2015 GMC YUKON SUDDENLY BECAME EXTREMELY DIFFICULT TO OPERATE WITH VERY HARD BRAKE PEDAL AND INCREASED STOPPING DISTANCE. I WAS ABLE TO BRING THE VEHICLE TO THE DEALER FOR SERVICE. THEY INFORMED ME THAT THERE WAS NO OUTPUT FROM THE ENGINE VACUUM PUMP TO THE BRAKE BOOSTER AND IT WOULD BE ADDRESSED UNDER A SPECIAL COVERAGE WARRANTY FROM GM REPAIRED. HOWEVER, AFTER FIXING THE COVERED PART OF THE VACUUM PUMP ASSEMBLY, THEY INDICATED THAT THE PROBLEM WAS STILL PREVALENT AND DETERMINED THEY ALSO NEEDED TO REPLACE THE BRAKE BOOSTER THAT WAS ALSO AT FAULT. THE BRAKE BOOSTER WAS NOT COVERED UNDER THE SPECIAL COVERAGE AND RESULTED IN A SIGNIFICANT CHARGE. IT SEEMS THAT THE BRAKING SYSTEM ISSUES ARE RELATED AND NEEDS TO BE LOOKED INTO FURTHER.

TAIL LIGHT/BREAK LIGHT WENT OUT FOR 2ND TIME. YOU CANNOT JUST PURCHASE A NEW TAIL LIGHT. THE DEALER STATES YOU HAVE TO PURCHASE A NEW TAIL LIGHT. THE DEALER WANTS $800 DOLLARS TO A NEW TAILLIGHT POD TO MAKE THE CAR SAFE AGAIN. CALLING GMC YOU NEED TO SPEND $100 DOLLARS FOR A DIAGNOSIS IN ORDER TO BE CONSIDERED FOR ASSISTANCE FROM GM WITH NO PROMISE OF ASSISTANCE.

LEFT REAR LIGHT ASSEMBLY INTERMITTENT OPEN CIRCUIT. WIRING CHECKS OKAY. GOOD POWER AND GROUNDS. NOTED THAT THE LAMP HOUSING HAS EVIDENCE OF CORROSION AT THE BASE OF THE MAIN CONNECTOR. THE HOUSING IS A SEALED UNIT (NO SERVICEABLE PARTS) SO THE NATURE ASSEMBLY NEEDS TO BE REPLACED. I AM A 37+YEAR A.S.E. MASTER TECHNICIAN AND STATE OF MICHIGAN MASTER TECHNICIAN SO I AM WELL SEASONED AT PROPER AUTO/LIGHT TRUCK ELECTRICAL DIAGNOSIS. THE LIGHT WILL GO OUT WHILE SITING STILL AND/OR IN MOTION. THIS IS A SAFETY CONCERN FOR OBVIOUS REASONS.
