2018 GMC YUKON Complaints

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.
