2018 GMC Yukon Owner Complaints

CAR IS NOT PERFORMING AS IT SHOULD

11/8/2020

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 ***

May 31st 2022-While driving on the highway, I lost control of my power steering. Luckily my husband was with me to drive it back home. June 1st 2022-Took it to a service center and was told it needed a part to fix the problem. We ordered the part, which would not be delivered until may 6th 2022. June 4th 2022- Went to drive, made it a couple blocks down the road when the ABS, electronic stability control, & the engine light came on. So I turned around to take it back home, only now my power steering was completely out, my car would not shift out of first gear. After arriving home, I attempted to put it in park but was unable to. My motor shut off but would not allow me to place it in park or turn the electric power off. The only option I had was to disconnect the battery. I let it sit for a few hours, reconnected the battery, now my car will not start at all. I am now unable to take my car to the dealership due to power failure Note: June 2nd & 3rd, my vehicle was not driven I did contact my local dealer to check if there were any open recalls, was told no

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.

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.

Headlights are terrible. Driving at night is treacherous because the headlights are not very bright unless I can use brights which seems like they could be low beam instead of high beam. With oncoming traffic it is hard to see the road and I get scared it may cause an accident, either hitting an oncoming car or going off the road myself. It's terrible. Others have commented on the headlights also asking me how can I see. There is no film on the covering over headlights. I Can see the bulbs just fine but they look burnt. My husband thought so too. Just scared driving at night. Need better Headlights!
