“Tail lights sometimes work and most of the time does not work. I see hundreds of complaints about this and nothing is being done about it! This will be my first and last time buying a gmc car. This is very dangerous and a very expensive problem to have!”Owner report · Electrical System · Aug 2019

“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.”Owner report · Exterior Lighting · Jul 2019
“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.”Owner report · Exterior Lighting · Jul 2019
“Tl* the contact owns a 2015 gmc yukon denali. While reversing the vehicle, the contact was informed that the brake lights were not illuminating. However, when the vehicle was in drive, the brake lights illuminated. Also, when the contact depressed the brake pedal to slow or stop the vehicle, the brake lights did not illuminate. The contact called coulter buick gmc phoenix (1202 e camelback rd, phoenix, az 85014, (602) 396-5994) and was informed that there were no recalls. The dealer referred the contact to the manufacturer. The manufacturer was not contacted. The vehicle was not diagnosed or repaired. The failure mileage was 64,000.”Owner report · Electrical System · Jul 2019
“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.”Owner report · Service Brakes · Jun 2019
“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.”Owner report · Exterior Lighting · Jun 2019
“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.”Owner report · Exterior Lighting · May 2019
“The rear driver side taillight does not work. Took it to the dealership and they said it was a problem they saw frequently, to just hit the light and it might start working. Otherwise it was a 800 dollar light to replace....if it is a frequent problem gmc should be fixing it... Are they going to pay for a ticket if I get pulled over or worse someone crashes into me? The problem comes and goes but has seemed to get worse and is not safe or legal to drive with the light how it is. Bad design of the light. And from what I have seen online I am not the only one. There a whole forums that people have the same issue.”Owner report · Exterior Lighting · Apr 2019
