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!

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.

Drivers side LED taillight stopped working and the whole assembly has to be replaced at $800. Led's should last life of the vehicle that is why you can't just replace a bulb. I have read hundreds of posts with the same issue. Gm should do a recall or offer a steep discount on the replacement.

The passenger side tail light is intermittent the dealer said that it would cost $875.00 for the part to fix. He said that it was a bad manufacturing job. And he also said that there were a lot of SUV's coming in with the same problem. Thank you

Drivers and passenger brake light go out intermittently. Passenger stays off for long periods of time. Looked into replacing no idea if it will fix the problem. Cost at least $500. Each parts only. I have seen so many other vehicles like mine same problem. Headlights also going out, water inside of cover. Led and turn signal went out on drivers side replaced for a cost of $900.00, (just for the headlight) again no guarantee it will keep working. Also battery went dead replaced battery. New battery also went dead. Car alarm went off the night before battery dead in the morning. Has been in the shop 3 weeks now. Same thing happens alarm goes off kills battery. Shows massive drain and set about 32 codes. The drain doesn't register after that. Recharge battery car is not running when this happens. Problem repeats every time after charging the battery. Something in the wiring is shorting out. Tested both batteries they both test good. Afraid of what will happen next with the electrical on the vehicle. Not sure if the lights have anything to do with this or not. When ordering headlight and asking about brakes told by dealer parts they sure are selling a bunch of these. I have had people driving down the road stop me to tell me my brake light is out. I did not know that the turn signal on the front was not working until a car pulled out in front of me while waiting to make a left turn. I got out and looked at the light and it was not working. I cannot drive the vehicle at all because it keeps draining the battery. I have a ase certified master technician working on the vehicle in a reputable shop.

The rear LED tailight goes in and out, while driving the car. The dealer will not fix the problem unless the light is not working, but because it is intermittent, we cannot get it to fail at the dealership. We have had this problem for 2 years and it is a safety issue as the tail light will not work.
