Both driver and passenger tail light/ brake light assemblies have failed. They started intermittently going out and then failed all together. There is a VERY common issue with these lights. They have been replaced at an approximate cost of $650 per light.

The rear taillights both went out due to a design issue with the LED circuit board - where the connections on the board crack and cause the lights to fail

- Palisade, MN, USA

Passenger taillight goes out. Replaced it twice now and now I have to do it again a 3rd time. They know of this issue but have done nothing to fix it or offer anything to help cover cost

Both rail lights went out at the same time. No reason whatsoever

- Columbia , SC, USA

Left tail light flickers, after reading internet comments learned that tail light board connections are made of very flimsy metal material, they crack with normal vehicle operations. LED lamps are fine but the power connections to the lamps breaks therefore it renders taillights useless. Replacement cost of those lamps are $700-$800 parts alone. On the internet there is some information I-??ll attach that pdf

The passenger brake light intermittently stops working.

- Charlottesville, VA, USA

The drivers side rear brake lights stopped working. GM did a warranty extension ( that admits an issue).but ours just expired.. this is an $800 to $1000 repair that owners should NOT have to pay.. GM refuses to cover this expense. This is an absolute SAFTEY ISSUE. Of course, any law enforcement officer will agree as they will write a safety violation ticket (as they should) I understand that owners are responsible for all maintenance of their vehicles, but this issue is a flaw in design. Most owners ( like us) can-??t afford to pay this outrageous price for a simple break light replacement. As the entity of government that oversees the manufacture of these vehicles, there MUST be a safety recall!! Honestly, I am disappointed that no safety recall hasn-??t been ordered for this issue. This problem is going to result in many many rear end accidents. Please fix this and save lives.

Driver side, rear lighting fixture not working. All lights for brakes, reverse, do not work. I had to replace the entire light assembly on the Passenger side previously.

- Valencia, CA, USA

The rear lights on my vehicle - including brake lights - intermittently stop working. I was unaware of this issue until I had someone follow me to my destination to make me aware. This is extremely dangerous that could lead to a wreck with the potential of bodily injury. GMC has issued a service bulletin (admitting to using faulty parts) related to this problem, however, they have limited the coverage to mileage and year. GMC should be required to issue a full recall on any vehicle impacted by this serious safety concern.

Passenger side brake light not working. Bulb replacement not available to purchase and you have to take to dealership for $800 plus repair. 72k miles on vehicle.

GMC has a bulletin -??recall-?? that stated that the tail lights of their vehicles were not illuminating on vehicles. In 2019 we took our vehicle in to have the defect covered because our passenger tail light stopped working. We are now having the same issue with our driver light but they are stating that the recall only covered one light with knowledge that both lights are defective. Only one light was replaced. They also had a recall on a defective air compressor that we paid $580 for but because of mileage it was not covered. I spoke with a rep by the name of Angellica in the complaint department that confirmed that the letters regarding the air compressors were sent in November of 2017 and I did not receive that notice during that time. I purchased the vehicle in April of 2017. If any part of a vehicle is defective, or poorly made coverage should not end and defective parts should be replaced. We are looking to be reimbursed for repairs and coverage provided for the second light on our vehicle. GM refuses to resolve this issue and is placing my family in danger with defective parts on this vehicle. I am looking for this to be resolved as soon as possible. This is poor business and the quality of this vehicle that is 5 years old is poor. Attached you will see the invoice from the dealer states that the wiring is bad but coverage was expired due to mileage. If defective parts are in a vehicle there should not be a limitation on getting them replaced. GM made this mistake and it needs to be corrected.

Rear tail lights inoperable and brake lights not operating. When I asked dealer about problem they said GM had extended the warranty on the tail light assemblies since they new there was a problem. I was never notified of them extending the warranty. Vehicle does not have any rear lights working which is extreme safety hazard.

I see almost 200 complaints and nothing has been done" not sure the point of this website, but, I'm going to put my 2 cents in. My 2016 Yukon denali passanger brake light has gone out, like many, many of other people. Why isn't this a recall? obviously, there is a manufacturing issue that needs to be addressed. After many videos I have watched I see that the circit board comes apart and can't be repaired but only replaced, at a extremly high price. I've also seen many tail light on these Yukon work off and on, so, randomly they can not work at any time and possibly get you rear ended. How do I file a civil action complaint to have GMC address this complaint and resolve this issue" please advise.

Brake lights cuts on and off when driving and third brake light is off on my 2016 vehicle also when step on brakes pedal sometimes goes to floor vehicle hard to stop a for sure dangerous situation

- Homestead, FL, USA

The rear lights keep going out, I was told by the dealership that I would have to pay to replace them because my vehicle mileage is outside of the extended warranty. This is a common issue among the 2016 GMC Yukon's and I do not think it is fair that I have to cover the repair.

- Rock Hill, SC, USA

I have already had to replace right brake light due to going out and now the left one has went out. These are very expensive lights. They are faulty and need to be recalled.

- Vicksburg, MS, USA

The rear tail lamps sporadically would light up with driving lights for awhile, but could never get failure to show up for dealer diagnosis. Finally lights went out completely except for side marker. When the brake lights would not work, car was not drivable. Dealer was then able to diagnosis and found short in led light circuit board assemblies has gone bad and both lights would need replacement. Lamps were replaced under 80/20 warranty offer. Total out of pocket cost to me/consumer: $492.75. I feel this is safety issue on newer model vehicle and lights service life should be much longer than 4 years. Especially since car was not drivable for 4 weeks because of concern with no brake lights, no rear lights at dark and chance of being stopped for a traffic infraction.

The contact owns a 2016 GMC Yukon. The contact received a letter from the manufacturer which suggested that the vehicle needed to be diagnosed in regards to the rear brake lights operation. The vehicle was taken to covert Buick GMC (11750 research blvd, ste D, austin, tx 78759, (512) 371-6075) to be diagnosed. The contact was informed that there was no failures or issues found with the rear brake lights. The dealer disregarded the letter after inspecting the vehicle. The manufacturer was not contacted. The contact stated that the issue recurred after the vehicle was returned to her custody. The vehicle was taken to an independent mechanic and the former diagnosis was confirmed. The vehicle was not repaired. The contact stated that the same dealer declined the purchase of the part needed to fix the vehicle. The failure mileage was 77,655.
