Rear (Tail/Stop) lights on both sides, would work intermittently. Turns out it-??s a known issue with the LED circuit boards. They consistently break in 2 places, leaving the vehicle with no tail lights/stip lights. GM knows of the issue, but since it-??s NOT CONSIDERED a Safety Issue, they do nothing. It-??s clearly a safety issue, as following drivers may not see lights, on the rear. Clearly, it is definitely a safety issue, as it can easily cause an accident, not knowing a car is there in the dark, or not knowing that the vehicle in front of them is on the brakes, and slowing.

Rear brake lights fail due to an issue known by GMC - MULTIPLE GMC YUKON and YUKON XL have this issue. All within the same year. The metal connector in the Brake housing fails and requires it to be soldered or a complete replacement costing consumers $800+ for replacement. A severe safety issue as the Brake Lights quit working!!

The right side break light works intermittently. It is out more than on. I was informed that there is a shortage in it and the entire assembly has to be replaced. I see countless GMC Yukons with the same light out. This is a huge safety issue.

I purchased a 2017 GMC Yukon Denali brand new off the showroom floor. I have maintained the services thru GMC dealership. I had to replace the struts and rear and front shocks due to hydraulic system leaking and locking up my brakes and causing extra pressure on my braking system to stop my vehicle. This cost me over $5000 to replace out of my pocket and I saw there was a previous recall in 2019 for similar problem but i was told my issues were not covered under the recall. I have also had to replace both taillights within 2years of purchasing my brand new vehicle and now they are out again. This will be my second time having to replace the LED tail lights that cost over $375 light which were stated as never go out of lifetime guarantee. You cannot just replace the bulb you have to replace the whole tail light which takes weeks to come in and then additional labor costs. The previous

Taillights and Brake light LEDs go out unexpectedly or work intermittently creating a safety hazard that drivers behind the Yukon are unable to see your taillights at night or when your braking causing Potential rear end collisions. For this common problem GM recalled the taillights of 2015-16 models, but the 2017+ models that still have the same exact taillights with the same issue but has not been recalled yet. Costing owners out of warranty $800 per taillight assembly. Please look into this safety issue.

- Evening Shade , AR, USA

The left rear tail light has gone out. There is no user replaceable bulb and this is a sealed unit. The deal has quoted almost $800 to replace. I feel a sealed unit should not fail prematurely and should last the entirety of the life of the vehicle. Had it been user serviceable, this would be a simple repair/fix.

- Greenville, SC, USA

Brake light on the passenger side has failed and non operational. I have researched this and found it is way to common to not be a manufacturer design issue.

- Wellsville , KS, USA

LED taillights have both gone out. One was replaced by a "service bulliten" and it didn't cost us. The other recently went out at approx 80k miles. These are supposed to last the life of the vehicle. Replacement cost is $750. After doing research, there is a recall for 2015-2016 GMC Yukon taillights that are the exact same product. I contacted GMC and they refuse to replace the known defect part. This is going to cause someone to get seriously hurt. They know the part is defective or they wouldn't have had a recall on the 2015-2016 models.
