The led brake light stopped working due to faulty circuit.

Right rear led taillight is intermittently not working. Not sure why it works at times, and not at other times, but when the taillight is not working neither is that brake light. This started about August 1, 2020.

Faulty tail lights. Tail light does not consistently stay lit. This faulty light is going to cause an accident

- Seaford, DE, USA

Driver side tail light went out, when you pull the light out it starts to work, replace the light back into the car and it dies again. This seem to be a issues with a lot of people. Its very costly to have to keep replacing led tail lights!

Taillight on drivers side goes out. It's been an intermittent issue as it comes on and goes out.

- Dayton, OH, USA

My passenger side taillight works sometimes, and other times it does not. I took it in to be checked out to find out a replacement is $800 as the taillight needs to completely be replaced not just a bulb. I have seen several vehicles like mine with the same issue and have also read many others experiencing the same issues. This has also been stated at dealership this is a known problem, but no recall. How can this not be a recall issue. This is a safety issue and needs to be fixed by GM.

My left driver's side brake light would work and then not work and I had multiple people telling me my left brake light was out. Then other days I was told it was working again. Now it is not working at all.

Defective led tail lights do not work all the time. Huge safety issue from a 50,000$+ SUV. GM will not cover repair if you go over a certain amount of miles. Multiple people have the same issue with these Yukon's. taillights are about 1200 each to fix ridiculous.

Passenger side tail light is out and could potentially be hazardous when operating vehicle. This is a huge safety concern and a law that every motor vehicle shall be equipped with at least two working tail lamps. GM has manufactured inadequate and faulty parts that one do not comply with the law that vehicles should be equipped with at least 2 working tail lamp and could cause serious harm to the customers whose vehicles are equipped with the defective parts. Many customers have reported concern but GM has failed to find resolution for the safety of their customers. The product has not been recalled and will only be replaced by GM under special coverage which has expired in most 2015-2016 vehicles. Defective parts need to be re-called for the 2015-2016 Yukon vehicles and replaced by products that are safer and non hazardous to customers before someone is seriously injured.

Both of my led tail lamp assemblies have failed over the pas year. GMC has replaced that oem with new parts and has md the old parts. Generally, if a break light fails you can replace the bulb for around $5 but when these assemblies fail it costs the owner around $700 to replace. Driving around without brake lights is a traffic violation. A car can not pass safety inspection without brake lights so the owner is forced to pay the money for the replacement part from which GMC profits.. why is this not a safety recall" GMC knows it is a manufacturing defect that can possibly cause a serious accident as a result.what is the NHTSA stand on this"

Brake light taillights intermittent turns on and off

- Pensacola, FL, USA

Both head lamps have moisture and it is hard to see the road. I have extended warranty and it will not cover lenses. No warranty will. Eventually the moisture will hard the led and hid components and they will not work at all causing a hazard to my family and others. My car has 37000 miles on it and is garage kept. These lamps are over $2000 to replace.

Brake lights stopped working almost was plowed into by 18 wheeler on I-75. Driver waved us over and informed us that he did not see us till right on top of us. Problem appears to be systemic enough that the GMC service department told us that it was common enough that they kept the brake lights in stock. Additionally there are numerous threads about this issue on the internet and even utube videos on where to remove material to access the offending circuit board to repair the known faulty circuit. The failure of these brake lights could have cost my family and me our lives. The dealership wanted to charge 1600$ to replace the brake lights. I reiterate the brake light failure is common enough that there are numerous threads on the internet to discuss the known weakness of the circuit board

Brake and taillight are going on and off intermittently. I can hit the side of the taillight and it will blink on and off sometimes. Looked up online and found it is a well known issue that GMC will not fix. This is a safety hazard.
