2015 GMC YUKON DENALI XL Complaints

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.

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!!!!!

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.

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.

AC CONDENSER LEAKING AT 72000 MILES, SO OUTSIDE OF WARRANTY. SHOULD BE COVERED REGARDLESS OF MILEAGE DUE TO A KNOWN ISSUE IN SPECIAL PROGRAM 17336. BOUGHT THIS CERTIFIED FROM DEALER IN 2017. AC JUST STOPPED COOLING A COUPLE OF WEEKS AGO, JUST BLOWS WARM AIR. IMPACTS DEFROSTING.

FAULTY, POORLY MADE TAIL LIGHTS THAT NEED TO BE ENTIRELY REPLACED (NOT JUST THE BULB) AT MORE THAN $700 EACH. WHEN SPENDING SO MUCH ON A CAR, THIS IS LITERALLY INSANE NOT TO BE COVERED UNDER ANY WARRANTY. GMC DRIVERS DESERVE MORE THAN THIS POORLY MADE LED LIGHT SYSTEM. THE PLASTIC WINDOW TRIM PIECES ALSO DETACH DUE TO CHEAP PLASTIC CLIPS. I'VE HAD TO LITERALLY USE DOUBLE SIDED TAPE AND GLUE TO STICK THEM BACK ON A $70K+ CAR. IT'S HUNDREDS OF DOLLARS TO REPLACE PIECES THAT ARE LITERALLY PART OF THE BODY OF THE VEHICLE.

OUR PASSENGER TAILLIGHT WENT OUT AND THE DEALERSHIP COST TO REPLACE IT WAS $811. I CALLED GMC CUSTOMER SERVICE AND AFTER 4 DAYS AND MULTIPLE PHONE CALLS THE BEST THEY COULD OFFER IN FINANCIAL ASSISTANCE WAS $80. I ASKED THE DEALERSHIP IF I COULD HAVE THE BROKEN LIGHT AND THEY WANTED ME TO PAY $50 TO TAKE IT WITH ME. A GOOGLE SEARCH TURNED UP MANY INSTANCES OF THIS HAPPENING. THE DEALERSHIP TOLD ME THAT THEY REPLACE 1-2 PER WEEK. THE TAILLIGHT REPLACEMENT ON THE YUKON FAMILY IS A SCAM. IT IS UNETHICAL FOR THEM TO CHARGE THAT MUCH FOR A REPLACEMENT WHEN IT IS INOWN TO BE DEFECTIVE. THE CAR IS LESS THAN 4 YEARS OLD AND HAS 66K MILES AND HAS NOT BEEN IN ANY COLLISIONS. JUST NORMAL ROUTINE USE RESULTED IN A COSTLY REPAIR AND, MORE IMPORTANTLY, IRRESPONSIBLE CUSTOMER SERVICE FROM THE GMC EMPLOYEES WHO WERE IN CHARGE OF HANDLING MY CASE.
