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.

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.

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)

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.

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.

'TAKATA RECALL' WE JUST PURCHASED OUR 2015 YUKON DINALI XL DECEMBER 20, 2018 AND HAVE HAD NOTHING BUT PROBLEMS WITH BRAKE LIGHT ( WHILE IN MOTION ) ON DRIVER-SIDE WORKING INTERMITTENTLY, SO WE REPLACED BOTH TAILLIGHTS WITH BRAND NEW ($700) ENCLOSED REAR LIGHT ASSEMBLY AND NOW WE ARE HAVING AN ISSUE WITH DRIVER SIDE ONCE AGAIN. I'M VERY PROUD TO BUY AMERICAN MADE PRODUCTS BUT AFTER SEEING HOW MANY GMC MONTHLY COMPLAINTS WITH THIS SAME ISSUE, YOU WOULD THINK THAT GM WOULD STAND BEHIND THEIR PRODUCT. I KNOW MYSELF BEING IN BUSINESS IF I HAD A COMPLAINS MORE THAN THREE TIMES A MONTH I WOULD TRY MY BEST TO CORRECT THE PROBLEM TO KEEP FROM HAVING A BAD REPUTATION AND HAVE A FUTURE CUSTOMERS!! I TAKE PRIDE IN MY WORK FOR WHAT OUR CUSTOMER PAYS, AND EXPECT THE SAME FOR WHAT I PAY!!

CAR WAS PARKED IN COVERED GARAGE FOR 2 MONTHS. BATTERY WENT DEAD. ATTEMPTED TO CHARGE BATTERY WITH 20 AMP CHARGER AND BATTERY WOULD NOT TAKE A CHARGE. ATTEMPTED TO START CAR WITH BATTERY BOOSTER PACK AND LIGHTS WOULD COME ON, BUT CAR WOULD NOT START SITTING IN VEHICLE WITH KEY FOB. CONSOLE DISPLAY SAID THAT STEERING WHEEL WAS LOCKED. CALLED AAA AND THEY CAME OUT TO REPLACE BATTERY. IT WAS THE ORIGINAL BATTERY...BUT HAD WORKED PERFECTLY WHEN CAR WAS PARKED EARLIER. NEW BATTERY ALLOWED LIGHTS AND ALL OTHER FUNCTIONS TO WORK, BUT CAR WOULD STILL NOT START. I CLOSED DOORS....HOOD AND THEN WAS ABLE TO START CAR WITH KEY FOB REMOTE STARTER. CAR WORKED PERFECTLY. SHUT CAR OFF AND TRIED TO START AGAIN AND WOULD NOT START NORMALLY, BUT WOULD START FINE REMOTELY. CALLED DEALERSHIP AND THEY HAD NOT HEARD OF THIS ISSUE, AND I MADE APPOINTMENT TO BRING IN. TWO DAYS BEFORE APPOINTMENT, CAR WOULD NOT EVEN START REMOTELY. ONLY THING THAT HAPPENED WAS THAT OUTSIDE MIRRORS WOULD RETRACT WHEN I TRIED TO START REMOTELY. PAID $90 TO HAVE CAR FLATBED TOWED TO DELEARSHIP. PAID $234.99 FOR DEALERSHIP TO CLEAR ALL CODES AND REPROGRAM. HAVE CALLED GMC SEVERAL TIMES AND THEY REFUSE TO ACKNOWLEDGE PROBLEM OR REIMBURSE ME. DEALERSHIP HAD NEVER SEEN THIS ISSUE BEFORE AND TOLD ME WHEN THEY SPOKE WITH GMC TECHNICAL DEPARTMENT THAT THIS ISSUE HAD NEVER OCCURRED. I FIND THAT VERY SUSPICIOUS. HOW COULD A BAD BATTERY TRIGGER A COMPUTER TO NOT ALLOW THE CAR TO START. THIS IS A VERY DANGEROUS SITUATION BECAUSE IF I WAS STRANDED ON A HIGHWAY AND THE BATTERY WENT DEAD AND A NEW BATTERY OR JUMP START WOULD NOT ALLOW COMPUTER TO START CAR, THERE COULD BE UNFORTUNATE CONSEQUENCES. I HAVE OWNED DOZENS OF CARS WITH THEFT DETERRENT SYSTEMS AND A BAD BATTERY THAT HAS BEEN REPLACED HAS NEVER TRIGGERED THE SYSTEM TO MAKE THE VEHICLE UNABLE TO START. PLEASE ADVISE. THANKS
