Tail light circuit (LED internal to housing) cracks, causing rail/brake light outage with no warnings on the dash for the driver. This is a material defect in the metal stamping used for the LED power circuit. Exacerbated by heat and vibration.

The passenger side brake/tail lights intermittently do not work. They work about 60 percent of the time and the other 40 percent they do not. I have read many complaints online about this issue and gm needs to step up and get it fixed. It is a safety issue.

Brake/tail lights have gone out. My car isn't even 5 years old. The repair is astronomical'at least $1500!!!

My driver's side tail light flickered for about 2 months before finally going out. The other side is now doing the same thing. It has 82,301 miles on it.

I have been having issues for about a year with the lights working intermittently. As of today, june 12 2019, they are out completely!!!! After going to a local mechanic he said the whole circuit was gone & would have to be replaced!!! I am in between jobs and do not have 2000.00 dollars to fix said problem. I have found several message boards who have all had the same problem with no help what so ever from gmc!!!!! This is ridiculous. When you may thousands of dollars for a SUV you expect it to last longer than 88,000!!! This isn't the first problem I have had with this SUV. So this needs to become a recall issue and gmc or the part supplier needs to fix this.

The left brake light failed with 57k miles. The right one then failed at 61k miles. The dealer wanted $735 each to fix them, as they claim they need to replace the entire LED housing. The dealer is well-aware that this is a common problem, and it would appear based on googling the issue that many others have experienced this failure from gm.

The tail light failed with no physical damage. I feel this is a latent defect that gm is aware of but will not take responsibility for it. This a sealed unit causing owners to pay exorbitant amounts to replace the unit. There are many reports of this item failing in the field within an unacceptable time period. Production date on our unit is apr/24/14, so just over a five year period on a vehicle with less than 80k miles.

We purchased a used 2015 yukon denali less than 6 months ago and both tail lights have now gone out. After reading about the issue, it seems like this is a very common issue with lights on this vehicle. Very unfortunate that gmc refuses to do anything about it.

Taillights working intermittent. This is a safety issue. I have google and there over a 100 complaints on car gurus with the same problem. This is a gmc safety problem. These yukon's are expense and I should feel safe while driving it. Taking it to the dealership this morning. I am asking a customer of gmc--- do the right thing and look into this as someone is going to get killed - no taillights could be a life threating safety issue. Gmc do the right thing. Look at all of the complaints with the exact same issue
