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.

My tail light is faulty. It is working some, shorts out, stops working, I hit a bump, it starts working again. Almost caused a crash, the lady followed me to the store to tell me it was out. Took it to the mechanic and it was working again without any repair. Does this everyday.

2017 GMC Yukon Denali 4WD. Rear passenger brake light intermittently fails while driving Confusing and causing motorists behind my vehicle to receive inconsistent intermittent brake warning lights to alarm other motorists I have stopped. Someone is going to end up slamming into me because of this. It-??s a dangerous common failure that needs to be address ASAP. I-??m not waiting but GM-??s executive corporate office will get the entire bill plus time lost and another BBB review.

The driver's side brake light and tail light has failed completely and the passenger side brake light and tail light fails intermittently. This is a safety issue that should be recalled. The vehicle only has 50k miles on it and I should not have to pay $800 per tail light to fix it!

Left and right braking lights some time do not work when braking. Only the reverse light will work while the braking light will not. To add, when the front headlights are on, some times the left and right tail lights (light that is on when not braking) and braking lights will not work. I have had two different people pull up next to me saying my brake lights are out in the last two weeks. However, I have observed when they are working in that same time span. The last two days, only the right tail/braking light is not work.

In the last year, both of the rear tail lights have failed in my 2017 GMC Yukon. To have the dealership replace the tail lights it cost +$750 per tail light for a car that is only 3 years old. I work with led lighting and on average, led lights should last for 5000 hours of use. There is no way that in the last 3 years we have utilized 5000 hours of drive time to warrant that these led's should be burning out. I believe that the led's that they are using are defective and a case needs to be made to see if GMC is having issues with the rear tail light led's, the parts are way too expensive to be failing after a few years of intermittent use.

Passenger side brake and tail light quit working took to dealership for repair. Dealership said they had fixed it and had not. Took back to them and they say they can't get one it's on back order. After looking into it myself it seems to be a very common problem that GM isn't doing anything to fix but put the same lights back in that will fail again. I've asked about an updated light that wouldn't fail again and the dealership seems to have no knowledge about the lights at all. GM needs to step up and fix the this issue as it is a safety problem.

The GMC Yukon models in all trims, have faulty led strips that cause the brake lights to fail on the left, and right brake light assembly. The frustrating part is it works intermittently, and when it's off a slight tap will momentarily bring it back on for the duration of the jolt. This leads me to believe that it's faulty connection inside the seals brake light assembly. There are thousands of complaints online on owner forums of GMC Yukon's. this is known as the new year models 18-19 are not having the same issue.

Drivers side led brake light strip inop. Dealer says its 650 per side plus labor to replace. GMC is aware of issue but will not stand behind there product. They also lie and say it's the first they have heard of this type of failure. This is a safety concern and customer is liable for a ticket that may result from faulty GM parts.
