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.
2017 GMC Yukon XL electrical complaints
Page 2 of 2: complaints 11 to 31 of 31, newest first, as owners wrote them.
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.
1) LED tail-lights fail intermittently - this is a known problem GM does not proactively address unless customers complain repeatedly. Puts driver and passenger in danger. this began happening at 25K miles. 2) AC condenser fails - GM will not address as part of a broader recall despite extensive late model customer complaints. This put passengers in danger on any road trip across desert terrain. GM has been unresponsive despite numerous calls asking for resolution. This occurred at 36k miles. 3) Electrical failings - numerous electrical failings - from entertainment system (at 10k miles), starter motor and internal lighting - all failing at 36k miles. the federal safety agency must take a look at these manufacturing defects - they are putting customers at risk!
The brake lights fail. First the left light failed, and two days later the right light failed. After researching, this is a common problem with GM and these models. The fix is not just a bulb- the whole rear light assemblies (each side) needs replacing with GM price quotes of $900 a side. We were over 1000 miles away from home.
The navigation and infotainment fails on a regular basis. Cannot use touch screen when it fails. Florida dealer said nothing wrong. The screen will turn to a clock without touching it. Cannot use navigation on many days. Had to locate a new doctor and the navigation failed! Happens when stationary or in motion. This started in may 10, 2018 through today, february 17, 2021. It is ongoing daily.
Right read tail light, brake light and reverse light stopped working at 61,135 miles on odometer reading for no apparent reason.
Intermittent brake light failure.
Rear passengers brake light flickers off and on causing a safety risk while driving. Previous years of same make and model are having same issues causing a shortage in $400-800 replacement of tail light assembly. Rather, gmc should recall and correct the original manufacturing quality to begin with.
The air conditioning in my 2017 yukon xl stopped blowing cold air. There is a known issue with gmc condensers. I brought my yukon to the dealership and was told that indeed it was the condenser which caused refrigerant to leak. However, it was not covered under the special coverage adjustment 17336 as my VIN # was not included for some reason. Same problem, but I have to pay for this out of my pocket - $1200. I live in the deep south, have small children, and cannot go without AC.
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.
Air conditioning quit working - clearly an issue as described in lawsuits and on-line search reports, not covered by manufacturer
The whole back tail light had to be replaced after failing. Poor design and a common problem on the 2015-2017 gmc yukons. There is a common area that breaks. Not only a big expense but also a large waste of material considering the whole unit has to be replaced. Cost is over $800.00 and the dealer buys back the old light for $50 seems a bit suspicious by gmc. These lamps are a sealed unit and were never designed to be repaired. As designed, if there is a problem, the lamp is replaced as a complete and very expensive unit.

Rear brake light is out and the vehicle isn't even 3 years old but over 36,000 miles. Dealership stated light is out so whole housing has to be replaced at $900/each.
While standing behind the vehicle and attempting to remove items from the rear cargo area, the lift gate randomly slams shut without notice or warning. This occurred several times while I was behind the vehicle. On some occasions my child(ren) was with me andwas almost hit as well. Since I am taller I was hit and was able to save my child from injury. I was hit several times on different occasions either I the head or in the back, depending on my position at the time. I ensured that I did not have the key fobin my pocket to accidently activate the closure, and I ensure that I did not accidently activate the closure sensor underneath the rear bumper area. Upon investigation the dealer determine the cause to be a lift gate module defect, as well as sensor and liftgate calibration.

While standing behind the vehicle with the lift gate open, and attempting to remove items from the rear area the lift gate randomly slams shut without notice or warning. On several occasions my children were in the way of the lift gate closing as well, however, since I am taller I was hit first saving my children. On several occasions I was hit in the head and it the back by the slamming rear lift gate. I ensured that I did not have the key fob accidently activated in my pocket and that I did not activate the closure sensor underneath the rear of the vehicle. Upon investigation by the dealer the cause was identified to be the lift gate module. The lift gate also required recalibration and sensor alignment.
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.
While parked and running with no driver in the vehicle, the vehicles key fob was locked in the car by a passenger exiting the vehicle. The passenger, a child, exited the vehicle and pushed the "door lock" button and then closed the door, locking it while running with the key fob in the vehicle. No warning alert noise was emitted and the vehicle did not automatically unlock the doors as designed. The weather was approx. 80 degrees. This hazard is not suppose to occur and poses a high risk of causing harm or death to an unsuspecting passenger. The hazard mitigation for this event failed.
While driving, the check engine light intermittently flashes. Vehicle runs extremely rough, sluggish at times. Dealer checked vehicle over a period of time and eventually confirmed random misfires. Unable to fix issue. Unable to determine cause. Vehicle was later confirmed to have a faulty transmission transmission replaced by dealer.
While driving with the navigation system actively navigating the destination path, the center console display screen turns to a black screen with no navigation features. The console randomly reboots and must restart. This failure mode can cause extremely hazardous driving conditions by delaying the drivers ability to follow the correct route. The dealer identified the cause to be the radio assembly. Radio replaced. Similar situation continue to occur with the replacement radio.
Upon driving vehicle water was observed to drip from upper left hand drivers compartment onto driver. The weather had previously been raining. Roof fabric was saturated and water was actively falling. The dealer confirmed the antenna assembly on the roof was a known failure mode for this hazard. Water can passively migrate through interior column. Vehicle had not been through any mechanical or automated washing system. Vehicle had not been subject to any external cause. Failure was caused by faulty manufacturing assembly process.
