UNKNOWN 4 times in the past 6 months, while parking the vehicle (turning into a spot, left or right) or slowly turning to pull up to a security code box, the car completely begins to lose power in drive, and has lost power while in drive twice. The dash begins to flicker to the point that you can't decipher which error codes are showing up. Most recently, the Trailer Brake Service message was on before it died. We were not towing anything, did not have tow mode on, or anything like that. The parking sensors were on for all these instances...regardless if we were parking or not. I can't confirm if that is the issue or not. It was pretty dangerous when I was pulling into my parents driveway along a busy road when the car did this before I was completely off the road...with my 3 young children in the back 2 rows. I know the battery is new. I did have the dealer look at the brakes about a month ago, because I felt they were soft. They said they were fine. They and myself checked the reservoir for brake fluid low. Was in normal range. Starter was replaced in March time frame. I feel this is related to the factory trailering system wiring harness or something.

I was driving and all my sensors came on stating they needed service including front camera, blind spot notification, lane departure, emergency braking etc. upon parking I exited my vehicle and walked around the rear of my car to find multiple wires hanging down burned from my exhaust. I took my vehicle to an automotive repair shop and not the dealer since it was no longer under warranty. They said they had never seen anything like it. It appeared the harness that holds the sensor module/wires disconnected from the car. It appears to be held in place with some sort of industrial glue. When it failed it was hanging in front of the exhaust and melted all of them. This disabled all of these sensors. I now have to pay for a new harness and to replace all of these sensors. In researching online it appears water intrusion has caused issues in some models and caused these harnesses to fail. I’m wondering if this is the cause even though this model isn’t part of the recall.

Adaptive cruise control system is not properly designed to recognize vehicles that are adjacent to the traveling lane and not directly in front of the vehicle. When traveling on the interstate with adaptive cruise engaged, we came around a bend in the road approaching an entrance ramp. There was a slow moving vehicle on the entrance ramp which was apparently identified by the adaptive cruise system as being in front of our vehicle in the same lane. The adaptive cruise caused our vehicle to brake violently while still in the bend in the road, which in turn caused us to swerve into the next lane where there was a car traveling adjacent, but just behind us. This was a very unexpected series of events, and could have resulted in catastrophic consequences had the adjacent car been any closer at the time. This is a major flaw in the adaptive cruise system. And it is compounded by the fact that the adaptive cruise system cannot be switched over to a manually controlled more traditional cruise system. This is a severe design flaw with the GMC Yukon. Some of this could be remedied by issuing a firmware update that allows the driver to disengage the adaptive cruise and switch to a more traditional cruise control method. But GMC has no interest in providing this update, even with multiple message board threads talking about the dangers of the adaptive cruise control.

There is a known issue with the wiring harness that warns the driver by vibrating the driver's seat. The original wiring harness will short out causing malfunction of the safety feature. The wiring harness has been redesigned to correct the defect, yet GM has not issued a recall. The safety feature is an important factor in the operation of the vehicle and when this feature does not work property, safety is compromised.

TRANSMISSION WENT OUT AT 88K MILES. MY SISTER IN LAW ALSO HAS A 2017 BOUGHT FROM ANOTHER STATE AND IT WENT OUT AT 79K MILES A WEEK AFTER MINE. PASSENGER SIDE TAIL LIGHT WORKS IF YOU PUSH ON IT THEN RANDOMLY GOES OUT (WIRING/ELECTRICAL ISSUE). OF COURSE THE DRIVERS SIDE TAIL LIGHT IS THE ONLY ONE ON RECALL. CRUISE CONTROL SET ITSELF AT OVER 100MPH AND RAPIDLY ACCELERATED UNTIL I HIT THE BRAKES. I RECEIVED A RECALL FOR THE BREAKING SYSTEM SPECIFICALLY FOR MY VIN NUMBER THAT NEEDS TO BE FIXED NOW THAT MY TRANSMISSION IS COMPLETE.

WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE DASH DISPLAYED NUMEROUS AND RANDOM ERROR MESSAGES: (WORDING MAY NOT BE EXACT) SERVICE FRONT COLLISION SYSTEM. FRONT RADAR BLOCKED. FRONT COLLISION SYSTEM UNAVAILABLE. THESE MESSAGES INDICATED A PROBLEM WITH THE FORWARD COLLISION AVOIDANCE SYSTEM. THE WEATHER ON THE PARTICULAR DAY VARIED. ERRORS OCCURRED AT VARIOUS SPEEDS. THIS HAZARD CAN CAUSE SERIOUS HARM IF THE SENSORS DETECT AN IMMINENT FORWARD CRASH IN ERROR AND APPLY THE BRAKES IN TRAFFIC. THIS DANGEROUS SITUATION IS LIKELY TO RESULT IN SERIOUS PERSONAL INJURY OR DEATH. THE ROOT CAUSE WAS DETERMINED TO BE RELATED TO AN ADDITIONAL FAILURE MODE IDENTIFIED IN THE OILY SUBSTANCE LEAKING FROM THE CONTROL BOX MOUNTED ON THE FRONT WINDSHIELD. THIS OILY SUBSTANCE WAS IDENTIFIED BY THE VEHICLE OWNER AND REPORTED TO THE DEALER.
