ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS, UNKNOWN OR OTHER
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.

SERVICE BRAKES
My brake lights work intermittently. If you tap the actual brake light they will flicker on and off. This puts others and my self at risk as the indicator for by braking system is not functioning properly. My vehicle has been to my local GMC dealer with a replacement cost of $950.00. I also received a written warning from my local police department. There are no warning notices.

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

ELECTRICAL SYSTEM, SERVICE BRAKES
The rear break lights malfunctioned and will quite working periodically there has been no inspection from a dealership at this moment and driving at night time puts me and my family at risk due to the fact that I could be rear ended and cause a major accident and my vehicle has no warning light or service light for this problem.

EXTERIOR LIGHTING
Just driving along yesterday in my Yukon, and when I stopped another driver pulled up to me and informed me my right rear brake light is not working. Upon further investigation, it comes in and out (sometimes it works sometimes it does not). I had this same issue with my 2015 Yukon, I would have thought GM would have this fixed by now, very expensive fix on my 2015, assuming it’s the same cost or close. Very dangerous to have a brake light out and reduce another drivers reaction time to stop and prevent a rear end collision. Furthermore the vehicle has no indication that a light or bulb is out, a lot of vehicles have that programming, surprisingly this does not.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

ELECTRICAL SYSTEM
This complaint is not in response to an event. It is a safety issue resulting from a common problem with this vehicle model, i.e.: brake light failure. The tail/brake light LED circuit board has a design weakness resulting in cracking of the board in 2 common locations, resulting in stop light illumination failures, which could lead to rear end collisions. GM has not issued a recall and their extended warranty allowance is inadequate, thereby leaving a significant repair expense falling to owners when the problem is encountered. The proper safety response is for GM to recall all of the vehicles with this style tail light in order to repair the circuit board weakness.

EXTERIOR LIGHTING
Taillights and brake lights inoperative. GMC knows of problem and refuses to repair vehicle outside of manufacturer warranty (lights failed after warranty period). I have seen SEVERAL other Yukons on the road with NO brake lights or tail lights. Extremely dangerous situation.

EXTERIOR LIGHTING
Passenger rear tail lamp/brake lamp failure. This is a known issue with GMC Yukon vehicles MY 2015-2019 with LED tail lamps. Metal within the lamp vibrates loose and cause the brake lamp to fail - thus resulting in no BRAKE Lamps illuminating at braking. This would be the second time this issue has occurred in 4 months, with the previous repair occurring rear drivers side and logged with NHTSA for this issue under 11436519. Opening this case as now the other side (passenger failed) with the EXACT same issue.

POWER TRAIN
We were on the freeway with my 4 small children. The freeway speed is 75 mph. The car had been jerking and hard shifting for over a week and I had it scheduled with a mechanic. As we were driving on the freeway, it lost total power as cars were going to the left and right around us. I was barely able to get it to the side of the road without being hit. This could have been tragic! I took it to the mechanic and the transmission is shaving a lot of metal (that was in the bottom of the pan). I have had to pay to have a whole new transmission redone. This is absurd with a car that is only 4 years old.

EXTERIOR LIGHTING
LED Taillight failure REAR DRIVERS SIDE. This seems to be a common occurance amongst GMC Yukon Denali XL, where the circuit housing for the LED board begins failure with fissure within the electrical contact points. The fissure soon erupts causing a shunt within the LED semiconductor and causing the brake lights to cease functioning.
