2016 GMC Yukon Lighting Problems

The LED left turn signal and blind spot detection ( safety feature) on the left outside rear view mirror suddenly stopped working. The is a TSB for warranty for 2016-2018 GM YUKON (#10-08-64-002D) and it states that the bulletin has been revised to include 2016-2018 year models for this defect. I am starting this claim because I am told by GM that my VIN is not covered under this warranty, yet I am experiencing the same issue stated in the TSB listed above.

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 $650.00 per light.

The contact owns a 2016 GMC Yukon. The contact stated that the taillights were inoperable. The vehicle was taken to the local dealer, who stated that the taillights needed to be replaced. The dealer informed the contact that the vehicle was no longer covered under Special Coverage Adjustment: N182180270 (Tail Lamps Inoperative). The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 104,000.

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

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

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 contact owns a 2016 GMC Yukon. The contact stated that while driving at various speeds, he was notified by other motorists that the brake lights were inoperable. Upon inspection, the contact discovered that the brake lights were intermittently inoperable while depressing the brake pedal. The dealer was notified about the failure and scheduled an appointment. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 77,000.

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

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.

Passage tail, brake light works when it want. One day it work the next day it don’t! I’m scared that I will get pulled by the police or somebody hit me in the back.

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.

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

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.
