Both tail lights fail. I just bought this vehicle at Ewald Automotive in Oconmowoc Wi a month ago with 100k and I know they were aware of the problem and so is GMC. I am not paying 900 bucks for each tail light. They are absolute junk. The left side someone already messed with it because there is electrical tape on it. Ewald laughed in my face.

The taillights started to randomly go in and out. The driver side taillight stopped working but the passenger side taillight still worked. Then a day later the driver side taillight worked, but the passenger side taillight didn-??t work. The next day we were going to look into this issue, and the driver and passenger side taillights were working, so we halted. We kept an eye on it and they seemed to continue to work for a few days with no issues, so drove it 20 miles to work. When I left work it was dark and I had a coworker check my brake lights before leaving and the running lights and brake lights were indeed working. By the time I arrived at home, I had no running or brake lights. This is and was a danger to others and myself as this could-??ve caused an accident driving and the taillights going out. The truck did not give a warning message that I had no taillights.

Both tail lights have stopped working. I purchased in 2019 with 60k miles and by the time the first tail light failed, I was over the 72k limit. If these lights failing was an issue before, it still is an issue and the special warranty should be extended to ensure replacement of faulty items.

Numerous reports of taillights and headlights not working properly and no recall like it should

- Headland, AL, USA

There was recall for N182180270 Tail Lamps Inoperative, for some reason my vehicle being a 2015 was not included. This issue is ongoing with my 2015 Yukon Denali and is dangerous while operating, it recently started and is intermittent. Also my vehicle has issues with hard shifting and jerking intermittently when taking off.... also a known issue for this year and make/ model of vehicle

Rear passenger running lights just stopped working. I have seen several people with the same issue. I think there should be a recall for GM to fix the issue they are clearly aware of.

Both my tail lights have failed. Dealer wants insane amount of money for new ones, so I opened up the lights and there is an obvious design flaw in the lights, to me it seems intentional at worst, incompetent at best. I am an electrical engineer, and there is no reason they should put a friction connection in the LED power bar, it is a glaring design flaw. Also having steering assist issue at low speed which was an issue that was supposed to be fixed in a previous recall service, but it is still malfunctioning.

Right brake light and tail light quit working for a few days, then returned to normal operation, both worked fine for a week then the left side went out and also returns for a few days. Now both are out except for one led per side per cluster. No brake lights except for the one over the gate. And turn signals work as they should.

Tail Lights don't work. Have seen several complaints about this problem. There is currently a lawsuit concerning this. GMC will only cover replacement if car has less than 72,000 miles. The replacement lights cost about $800 each. Having it looked at now. Fear that I will have to pay replacement costs.

Drivers side tail light intermittently works, doesn't work all the time. Passenger side brake light stays on continuously, never changes.

- Milltown, IN, USA

Stop and tail functions inside the tail lamps have become inoperative. Purchased vehicle used and falls just outside of the special coverage adjustment; N182180270. This is still very much a safety issue, even though it's 1 month longer than the 6 year cutoff.

- Chico, CA, USA

Purchased a 2015 Yukon denali back in November 2019. Since purchasing the vehicle we have had to replace the battery, transmission, ac compressor and expansion valve (which still isn't working correctly, because it doesn't blow cold air), and the black panels that are in between the windows. Also, both tail lights have decided to quit working.... which concerns me greatly because cars behind me don't know when I am stopped or applying the breaks. Stopped or have my foot on the break.

Passenger side tail light/brake light goes out intermittently at random. I purchased car used in February 2020 and was informed soon after by friend that my tail light was out when leaving their home. It was working the next day when I checked. I now watch it and see that it works only sometimes. Cost to replace is approximately $700 assuming only a replacement light is needed and nothing else is wrong. Based on the multiple complaints I have seen this sounds like a wiring issue that should be a manufacturer recall for safety reasons.

- Olive Branch, MS, USA

Rear break light. Internal wiring of the tail lights cracks leading to tail light failure. The failure does not trigger any warnings and the driver is unaware of this failure unless they preform a pre trip inspection.
