Intermittent failure of one brake light while moving. Vehicle has only 38000 miles. This appears to be a common complaint (judging by car forums). I understand GMC makes an improved version of this assembly. Given the potential safety issue, this should be a recall.

Both brake lights stopped working at the same time. There is no fuse. Online reports show many people with the same very dangerous, huge safety issue of their brake lights failing. The car 3 years 2 months old.

Passenger brake light is intermittent. Clearly issue with the internal assembly.

Passenger rear brake light is out. All led lights will not light up with running lights on or the brake depressed.

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.

Tail and brake light no longer working.

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.

So my brake light on rear all have gone out due to bad led lights or some known component goes bad. #2. Fuel pump is bad. #3 radiator has a crack in it. This is a 2015 Yukon.

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.

One of the break lights is out. They have made the brake lights in such a way that you can no longer just replace the bulbs but have to replace the entire unit at a cost of $885. There is a design flaw in the 2015 and 2016 models that causes the brake lights to fail. GMC is aware of it and did extend warranty coverage so that if you are "lucky" enough to have them fail with less than 72,000 on your vehicle they will replace them at no cost but after that they will not. They know the product and it should be recalled. It is a safety issue for people to drive around without brake lights because it costs nearly $900 a piece to replace them! perhaps they shouldn't have turned what used to be an cheap, easy thing to fix on your own into a $900 repair in the first place. Now that they have they should at least stand behind the product.

My passenger brake lights stopped working. Apparently the only way to fix is to buy a whole new unit which costs $300-$500.

Passenger rear brake lights quit working. Appears to be a defect in the design that causes a break in the circuit on the light assembly. Repair can be manually down by cutting through plastic of assembly and soldering break, or replacement of entire light assembly. No accidents - just normal driving.

2015 rear brake lights work intermittently and need to be replaced or repaired. GMC know there are numerous complaints about this problem and have done nothing. Huge safety issue!!.

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.

This 2015 Yukon slt has 2 failed rear taillights and brake lights. There is no indication of this failure in the instrument panel. My wife was advised by text from a friend these lights were out. The replacement assembly is appx $500. 00 per side plus installation. I was advised this is not a warranty item and it is also a common failure on these vehicles. Not sure when the failure occurred. The 3rd raised light was operational when the brakes were used. First noticed around July 10, 2020. I have several cars from 2002 on which warn of a light failure. These led lights were advertised to last for extended periods. This issue is dangerous and uacceptable.

The led brake light stopped working due to faulty circuit.

Intermittently defective tail / brake light. Led circuit breaks. Known issue. Dealer wants $800 to fix. .

The contact owns a 2015 GMC Yukon xl. The contact stated that while depressing the brake pedal the rear brake taillights failed to illuminate. The vehicle was taken to keweenaw Buick GMC located at 608 quincy st, hancock, mi 49930, to be diagnosed. The contact was informed that the rear brake lights were defective and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but provided no assistance. The failure mileage was 102,000.

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.

Brake light goes out due to wiring issues.

Rear brake lights assembly failure (leds) both driver and passenger. Common failure known to GMC Yukon customers.

Brake lights intermittently not illuminating and going out. Both driver and passenger brake lights.

My brake lights will work one minute and go out the next. I had a friend and my husband tell me that when they were following me the light was out when I stopped but at the next stop or at home it would work. This has been happening for months. Last week I took it for state inspection and the inspector said it was out I had to get it replaced. When I pulled forward it started working again to pass inspection. Today I took my Yukon to the dealership for an oil change and it went out again. Others waiting told me this is a recall on other year/models with GMC. There is a short in the circuit panel.

My car has 60,000 mi on a 2016. The rear brake light went out on passenger side and I am being told by dealer I have to replace the complete assembly- not just a bulb. Estimated cost is $800. 00 for one side. In researching I have found this issue is not uncommon. This is ridiculous for what should be the cost of a bulb.

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?.
