2018 GMC Yukon SUV 4WD

2014-2018 Chevy and GMC's have a problem with cycling of the thermostat that causes stress fractures on the radiator leading to coolant leaks. Attached are GM bulletins on the 2014 and 2015 models. As one can see they have provided special coverage on the 2014 models to 5 years or 100000 miles for this problem.(Bulletin 15829) This is not true of the 2015 through 2018 like mine. Although they use similar verbiage in the bulletin P11513A and P11513F. It should be noted that Bulletin P11513A and F also applies to 2015 Cadillac Escalade Models, 2015 Chevrolet Suburban, Tahoe, 2015 GMC Sierra Denali, Yukon Models, Yukon Denali Models Equipped with 4.3L, 5.3L or 6.2L Engine (RPOs LV1, LV3, L83 or L86). ***Basically this is a safety hazard because when traveling highway speeds it puts car into reduced power mode and you can only drive very slow on highway or be stranded on side which is just as dangerous ***

Side rear brake lights work intermittently, often cutting out and losing all power while driving.

PASSENGERS SIDE WHEEL BEARING BAD AT 37,000 MILES MAKING LOAD HUMMING NOISE WHILE DRIVING

REAR SHOCK IS LEAKING AND RIDE IS ROUGH (BOTTOMING OUT) CAN'T FIND NEW SHOCKS.

MY VEHICLE HAS JUST OVER 55,000 MILES ON IT AND THE RIGHT FRONT SHOCK IS LEAKING. NOT VERY MANY MILES TO BE IN NEED OF A NEW SHOCK ON THE MOST EXPENSIVE SUSPENSION SYSTEM GM MAKES.

ON 3/20/21 I WENT OUT WITH THE FAMILY OUT GOT TO OUR DESTINATION WELL BUT WHEN I STARTED MY VEHICLE TO GO BACK HOME I GOT A MESSAGE ON THE DISPLAY "SERVICE POWER STEERING DRIVE WITH CARE" WHEN I WENT TO TURN THE STEERING WHEEL TO DRIVE I COULDN'T BECAUSE IT WAS TOO HARD, AFTER FIGHTING IT, I WAS ABLE TO DRIVE MY CAR BACK HOME WITH MY FAMILY IN IT. TODAY 3/22/21 I CALLED GMC TO DO A COMPLAINT AND ASK IF THERE IS A RECALL FOR THIS ISSUE ON THIS TYPE OF VEHICLE SINCE I DON'T HAVE ANY WARRANTY ANYMORE ON THE VEHICLE DUE TO PASSING THE 36 MONTHS BY 1 MONTH BUT NOT BY MILEAGE SINCE I HAVE 28500 MILES ON IT. I WAS TOLD BY THE GMC REPRESENTATIVE THAT AT THIS TIME GMC DOES NOT HAVE ANY RECALLS FOR THIS VIN NUMBER. AFTER DOING MUCH RESEARCH I FOUND THAT THIS IS A VERY RECURRING PROBLEM WITH GMC, CHEVROLET AND BUICK VEHICLES. ON THE PAST THEY HAVE DONE RECALLS FOR THIS TYPE OF PROBLEM BUT THE LOVELY AUTOMAKERS AND LOBBYIST ARE FINDING THE LOOP HOLES SO THEY ARE HELD ACCOUNTABLE FOR KNOWN MISTAKES UNTIL SOME FAMILY TRAGICALLY DIES IN AN ACCIDENT DUE TO AUTOMAKER NOT BEING HELD ACCOUNTABLE FOR KNOWN ISSUES. PLEASE DO SOMETHING ABOUT THIS ISSUE, TOOOOO MANY CUSTOMERS HAVING THIS ISSUE AND NO ACCOUNTABILITY ON AUTOMAKERS BEHALF.

AIR CONDITIONING CONDENSER REFRIGERANT LEAKED, PREVENTING AC FROM FUNCTIONING. COULD LEAD TO VISIBILITY ISSUES DUE TO DEFROSTER NOT FUNCTIONING PROPERLY. REPORTED PROBLEM IN NHTSA 10166241 (GM SPECIAL COVERAGE 17336), BUT VEHICLE HAD CONDENSER SHIELD USED AS 'SOLUTION' TO PROBLEM. STILL LEAKED AND GM WOULD NOT COVER REPAIR COSTS.

THE FRONT SHOCK ABSORBERS ON MY 2018 YUKON DENALI ARE LEAKING. THE CAR IS 2 YEARS OLD WITH APPROXIMATELY 67K MILES. GMC HAS THE ABSORBERS ON BACK ORDER AS THEY ARE APPARENTLY BEING REPLACED FREQUENTLY. I THINK THE SHOCK ABSORBERS HAVE DESIGN FAULTS THAT ASSURE THEY WILL NEED REPLACING WELL BEFORE THE NORMAL LIFE OF THE PRODUCT AND THEREFORE SHOULD BE RECALLED AND REPLACED WITH A BETTER PRODUCT. I CONTACTED GMC CUSTOMER CARE AND THEY OFFERED TO REPLACE THEM FOR $1,450 PLUS TAX WHICH IS NOT AN ADEQUATE SOLUTION - THEY SHOULD REPLACE THEM FOR FREE.

AIR CONDITIONING SYSTEM DOES NOT COOL THE AIR.

I WAS DRIVING MY VEHICLE AND EXITING THE HW. THE REAR WHEEL OF THE DRIVER SIDE BROKE OFF AND SEPARATED FROM THE CAR WHICH CAUSED MY CAR TO HIT THE CEMENT BEERIER ON FRONT AND THE SIDE OF THE DRIVER SIDE OF THE VEHICLE. THEN THE CAR TURNED 180 DEGREES AND HIT THE BEERIER ON THE PASSENGER SIDE AND THE REAR OF THE CAR. THE AIR BAGS NEVER DEPLOYED AND WE DISCOVERED THAT THE WHEEL BROOK OFF OF THE REAR AXE. NO DAMAGE TO THE WHEEL. SEVERAL INDUSTRY EXPORTS STATED THAT THIS SHOULD NEVER HAPPEN.

CAR IS NOT PERFORMING AS IT SHOULD

WHEN RUNNING FROM TIME TO TIME, THE SERVICE STABILITRAK MESSAGE APPEARS AND THE ABS LIGHT MOMENTARILY APPEARS AND DISAPPEARS, AND THE AGENT WAS DETECTED, BUT THE DEFECT WAS NOT DISCOVERED, AND IN THE DETECTION OF MY FRIEND'S DEVICE, CODE C0800 APPEARED, BUT THE AGENT REFUSED TO LOOK FOR THE DEFECT IN THE CODE WHEN I EXPLAINED IT TO THEM, AND I STILL WAIT WHEN IT WILL COME BACK AND WORRY

LOSS OF BRAKE ASSIST AT SPEEDS UP TO 30MPH VACUUM PUMP WAS REPLACED AND REPROGRAMMED IF THE BRAKE MODULE AND STILL HAPPENING

TL* THE CONTACT OWNS A 2018 GMC YUKON. ON SEVERAL OCCASIONS, WHILE DRIVING VARIOUS SPEEDS, THE FORWARD COLLISION AVOIDANCE SYSTEM AND LANE DEPARTURE FUNCTION BECAME INOPERABLE. THE VEHICLE WAS TAKEN TO GERRY LANE BUICK GMC (6615 FLORIDA BLVD, BATON ROUGE, LA 70806, (225) 341-5413) WHERE IT WAS DIAGNOSED THAT THE MODULE FOR THE FORWARD COLLISION AVOIDANCE SYSTEM AND LANE DEPARTURE ASSIST MODULE WERE FAULTY.

NUMEROUS TIRES HAVE HAD SIDEWALL FAILURE. WE HAVE HAD TWO TIRES WITHING 8 MONTHS (7000 MILES).

MY FRONT END MAKES NOISES WHEN I TURN WHEEL OR STOP.I TOOK IT TWO THE CARMAX SERVICE DEPARTMENT AND THEY COULDN'T FIND ANYTHING WRONG.BUT IT'S STILL MAKING THE NOISE

THE CAR WAS PARKED, ALL OF A SUDDEN WE HEARD A BOOM AND THE REAR WINDOW HAD EXPLODED OUTWARD AND SHATTERED, WITH THE LATCH STILL ATTACHED TO THE REAR TAILGATE. THE HYDRAULIC ARMS WERE UP AND EXTENDED, INDICATING THE WINDOW HAD POSSIBLY TRIED TO OPEN, BUT DIDN'T UNLATCH, AND THEN SHATTERED. NOBODY WAS INSIDE THE VEHICLE OR HAD THE KEYS ON THEM, SO THE REAR TAILGATE WAS NOT ACTIVATED IN EITHER WAY.

I WAS DRIVING MY 2018 YUKON DENALI ON A 3 LANE INTERSTATE WITH GM'S NEW ADAPTIVE CRUISE CONTROL TURNED ON.. ANOTHER DRIVER CUT IN FRONT OF ME FROM THE RIGHT. ADAPTIVE CRUISE SLAMMED ON THE BRAKES ALMOST CAUSING A REAR-END ACCIDENT BY OVERCOMPENSATING. THIS HAPPENED MORE THAN ONCE ON A 2000 MILE TRIP IN DIFFERENT TRAFFIC CONDITIONS. IN CONTACTING MY DEALER, THEY CALLED GM AND WERE TOLD IT COULD NOT BE FIXED BECAUSE OF EXTENSIVE SUPPOSED CHANGES TO THE VEHICLE. HOWEVER, OTHER GM VEHICLES HAVE A SHUTOFF THAT WOULD ELIMINATE ADAPTIVE CRUISE AND LET YOU NORMALLY OPERATE CRUISE CONTROL. I WAS THEN TOLD BY THE DEALER THAT I WOULD NEED TO CONTACT GM DIRECTLY. THE CASE NUMBER IS 8-4468390871. IN PURSUING THIS WITH SEVERAL GM REPRESENTATIVES, THEY CLAIM THERE IS NO FIX WITHOUT EXTENSIVE CHANGES IN SOFTWARE, WIRING, AND PROGRAMMING. BUT ALSO REVEALED THEY RECOGNIZED IT IS A PROBLEM AND HAVE PROVIDED A SHUTOFF ON FUTURE GM YUKON DENALI VEHICLES. IRONICALLY, THIS FIX IS ALREADY ON A BUICK ENVISION, ACADIA, AND POSSIBLY A CHEVY EQUINOX. GM'S RESPONSE IS TO SPEND MY MONEY ON A NEW VEHICLE TO FIX THEIR PROBLEM. MY VEHICLE ONLY HAS 2300 MILES ON IT. I CONSIDER THIS ADAPTIVE CRUISE FEATURE AN ACCIDENT WAITING TO HAPPEN WITH DRIVERS NOT EXPECTING THE RADICAL BRAKING AS WELL AS OTHER DRIVERS NOT EXPECTING IT, THUS POSSIBLY CAUSING CHAIN REACTION CRASHES.
