This can be researched by hundreds of videos on youtube. Poor design causes the metal to break inside the led rear tail lights which makes them inoperable. These are unsafe when these go out and it is very common. General Motors does warranty their lights nor is there a recall.this is a costly repair and a safety issue

Brake light on vehicle works intermittently and is no longer safe. This is a problem GMC is well aware of and no solution in sight. Cheap metal board brakes inside the lens and leaves you with no brake light. I do not want my family to be rear ended because of this professional grade" brake light failure, at any time on road.this is a 2016 GMC Yukon with 22710 miles as I write. Brake light has failed while moving on the city streets. This failure is currently on the passenger side brake light. Trying to make appointment for repair of this professional grade brake light" before the other one brakes and put my family at risk of a accident.

Rear led taillight went out our only 3 year old 2016 GMC denali. This effects the stop, tail, and turn lights. These led lights are not repairable and the whole assembly has to be replaced. GM charges an astronomical price of around $700 for each side. It is very hard to find any used ones and according to part dealers GM has a 'bounty' on any used ones to turn back in. Obviously GM is aware of this problem and needs to address it as not only as good customer relations but it's really a safety issue as well.

2016 GMC Yukon tail light not working. Started not working for a day or two and then worked again and then quit completely.

Brake lights are shorting out causing them to work intermittently. Circuit is broken inside the sealed portion of the light preventing repair.

- Gurley, AL, USA

The tail light stopped working and cannot change out the led bulbs, it is a break some where the the wiring.

- Rexburg, ID, USA

The contact owns a 2016 GMC Yukon. The contact stated that the passenger side brake light failed to illuminate when the brake pedal was depressed. The vehicle was taken to greiner Buick GMC (14555 civic dr, victorville, ca 92394, (760) 245-3451) where the contact was informed that the tail and brake light assemblies needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 81,000.

- Apple Valley, CA, USA

Internal circuitry of passenger tail light cracked in multiple locations causing the led's that provide running and stop functions of the light to fail. The car was not wrecked or damaged in any way. Appears as if metal fatigue from bumpy roads perhaps causes the circuitry to fail at at least 2 weak points in the metal circuit. The problem was pointed out by a trailing policeman while stopped at a red light, he kindly notified me that the entire light was out.

Left rear led brake/tail light went out at approximately 43,000 miles. In doing research this is a common problem in GMC Yukon. It seems to be just after warranty expires as mine did. The cost to replace is anywhere around $800. I have no choice but to get it replaced as it is a safety issue. Research also says these led's should be lasting much longer than they are on this make and model. I feel with the numbers so high GMC really needs to look into a recall and get this problem fixed or help compensate some of the cost. Also, this part is not readily available so we go weeks with no brake or tail light until it can be repaired. This is so not safe!!

- Sutherlin, OR, USA

Drivers side tail light/brake started failing, only working intermittently while driving and while stopped. Now only a small outer corner of the the light is working.

- Visalia, CA, USA

Both of the taillights work intermittently. I have taken it in to the GMC dealer only to be told it will be $2000 to replace them both. This is a factory problem. Sometimes one works, sometimes they both work and sometimes neither work, in motion, stationary, all streets and at any time.

- Ellensburg, WA, USA

The led lights on the left rear tail light are defective. They flicker or do not work at all. The vehicle has less than 43,000 miles. To fix the issue requires replacing the entire tail light at a cost of more than $800. It should be a recall on a defective part.

- Steamboat Springs, CO, USA

Tail lights alternating not working. There seems to be some electrical issue with the led tail lights. This is a massive problem and all over the internet. GMC is charging $1000 per tail light to fix despite this being a defect. Many companies and youtube videos popping about a bout this: www.ledfix.com/yukontaillightrepair.html https://www.youtube.com/watch?V=nnldjpymdzc

- Walnut Creek, CA, USA

Brake light/turn signal fail with no warning to driver. The failure requires replacement of the entire component. Dealer quoted $826 to replace assembly. I understand that these have a very high failure rate. Along with the lack of warning to the driver that their rear brake lights and turn signals are not working this is serious problem. The failure rate is so high that several independents are repairing them

- Baltimore, MD, USA

Rear brake light on the drivers side was working intermittently and now will not work at all. I was not in an accident and no damage has occured to the part. It just stopped working. This is an led and is not supposed to go out according to GM. GM is aware of this issur and will not fix it.

- Columbus, OH, USA

The right side tail light has stopped working. It's going to cost $850 to replace the light. This vehicle only has 42K miles on it. This should not be a problem with a $58K vehicle. Researching the issue shows that this is a huge problem. So much so that there is not a tail light to be had for my vehicle! there is a shortage from all that have went out.

- Vicksburg, MS, USA

Brake light stopped working but it cant be repaired unless you replace the entire light assembly. This is a very common problem. So much so, it is a 3 month wait to get it! not to mention it costs $500-800!! now I cant even drive the car because of the safety concern of someone rear ending me. GMC needs to recall these or pay the 3 month car rental fee.

- Aurora, CO, USA

My rear tail lights (both driver and passenger side) keep flickering and go out intermittently. They are led lights, not bulbs; therefore, they cant simply be replaced without incurring a cost of $800+ per light. The dealer claims there is no recall on the lights.
