Rear tail light stopped working going on and off and according to the auto electrician my vehicle could have gotten on fire due to the faulty lights. Upon searching for answers to why my vehicle's back lights were not working, I came upon many other consumers experiencing the same issue. Not only is the cost to replace the lamps so high, we risk in driving a vehicle that could catch fire for such cheaply made lights. And I state this because the auto electrician said that the wire would heat up while driving the vehicle and cause further damages to my Yukon. While driving, you can hear a clear chirping noise that is produced when you brake. This also happens while the vehicle is stationary.
The passenger tail light was only working intermittently so I had the whole thing replaced for $750. Now my driver side one is only working intermittently. Also my passenger headlight started accumulating moisture and now the whole led strip doesn't work. There has to be an issue with the company making them!
The passenger side brake light will not illuminate. I'm not exactly sure when it began, when I first found out it would sometimes work and sometimes not, now it has be staying completely off.
The left tail light was not turning on when starting the car. Left tail light does not come on when pressing brake. At first, it was intermittent and now it does not come on at all.

First, passenger side tail light was going on and off. Sometimes the whole panel would not turn on. Then, a few weeks later the other tail light started doing the same thing and now both brake lights do not come on. They will sporadically start working again ever so often.
The right rear brake light led strip no longer works. I have noticed that this is an on-going issue with other consumers. The dealer wants $650-$750 to replace. Most of the time, it is a wiring issue that needs to be repaired. Unfortunately, the plastics are glued together preventing access to make the repair.
The rear passenger brake lights just randomly stopped working. Not a bulb issue as it is an led panel of lights. The back up bulb still works, but the brake lights don't. dealer says it happens a lot to these cars, and have to buy a whole new unit. This is a safety issue - break lights failing due to poor wiring. Again not a replaceable bulb issue, it is due to a wiring issue within the lighting unit itself
Rear tail lamps only work every now and then. Happens while moving and stationary. The rear tail lamps are cheaply made internally that the circuit board for the led lights easily breaks with regular driving. Its and obviously know issue for GMC because there are businesses online that there sole income is to repair these tail lights on 2015 to current Yukon/ Yukon XL models. Taken my 2015 Yukon in before warranty was out and GMC dealer doesn't want to warranty and doesn't want to repair. Tells owners they'll have to buy a new tail lamp at $800 a piece. Total rip off.
Tail lamps would intermittently operate. At times none would work at others some would work. And others all would work. GMC finally addresses this with: N182180270 (special coverage). GMC was aware of this issue on or prior to November 26, 2019. They stated notifications to customers would begin on December 12, 2019. I was notified today 2-12-2020 well after GMC was aware of issues. GMC allows for warranty of 6 years after placed in service or 72,000 miles. Since my vehicle had 902 miles at time of purchase my warranty expired at 72,902 miles. Had GMC made me aware in December or too after knowing in late Nov 2019 I would still have been under warranty for a resolution to fix issues. There willful negligence in failing to notify me hindered their available warranty under special coverage of no use to me to my detriment of several hundred dollars (~$1800 usd).
Rear taillight does not work. Searched online and found that this is a very common issue, GM refuses to fix and tries to charge $800 to replace whole tail light assembly
For the past 3 years I have taken my truck into the dealership with complaints about intermittent brake light function. Specifically the lr light was not working. Once I was told I had to replace the entire assembly $800 - I came in to have the repair done, then I was told there was no issue. I returned again when the police gave me a warning about the same light. Was told no issue. Several times I have been alerted by other drivers that the light was out - sometimes it works if I smacked the exterior of the assembly but not consistently. Now - all of the brake lights are out lr/rr and the bar. I cannot drive it safely and I cannot believe that the only option is to pay several thousand dollars to replace it. Many have the same complaints. This should be a recall! we already paid several thousand dollars to buy this truck - it should not have these issues so early on. I have seen many other Yukon's on the road with the same issue. My car is 2015 - the problem started almost immediately for us after purchasing. This is not acceptable.
The taillights will short out and stop working. The true signal works but the brake and running lights stop working. The touchscreen display isn't working on some parts of the screen. For example, I cannot change the time because the toggles to change the numbers up or down will not work.
At 32,000 miles we had our back tail light go out. GMC replaced it at cost to them which was around $280. Less than 6 months later the other tail light went out and dealer told us 'lights go out'. we paid full price $680 to have it replaced. Now our left tail light is out again and it'll be another $680 or more to be replaced. This is ridiculous. They are led tail lights. These she last a very long time. Thousands of others are having this problem. Car gurus has a blog solely about this. The odd thing is they are mostly 2015 Yukon's. a recall needs to be done on this problem and the thousands of people dealing with this should be reimbursed for replacing these tail lights over and over! if you pay 60,000 for a car you should not go through this.
Both of my taillights went completely out on my 2015 Yukon denali. I was told by a stranger who asked me to pull over that both lights were completely out (specifically inside our residential community). I have a four year old and a baby with my hands full. I was so grateful to the stranger that informed me- preventing a potential accident with my babies in the car. I called to see how much the replacement lights would be. With labor we were looking at $2,000 at the dealership! to me this was outrageous... especially after doing research and seeing that many 2015 Yukon denali owners have the same issue and this is not yet a recall for GMC! when will the issue be recalled?... heaven forbid not after a horrific accident from a blatant safety issue that they are not taking seriously! we proceeded to call GMC complaint department to file a complaint- the woman lied and told me she had never heard of this being an issue but even if she had she couldn't tell me.... needless to say my complaint went upon deaf ears at GMC. I had no other choice but to order two new taillights through GMC.... now that I am awaiting my order I'm thinking that I could experience the same issue with my new lights. Adding to my frustration, the parts department solidified that the taillight issue is incessant with this make, model and year... and they need to keep my taillights when they issue my new lights. I couldn't help but find this strange and became skeptical that they need to keep my faulty taillights. I'm frustrated and nervous driving my vehicle with my children. I'm worried for our safety and I pray my complaint is taken seriously. GMC needs to be held accountable for their faulty products. My left light is half way out now bc my dad tried to weld a bridge to turn the lights back on in the mean time... didn't end up working.
Both brake lights went out. Dealer said had to replace entire fixture. Not covered under bumper to bumper extended warranty purchased. Safety hazard that many other 2015 Yukon owners have experienced. Trim/seal appliqus around door windows also coming off and also not co weed under B2B warranty. Shottily made vehicle.
Driver side rear brake light working intermittently, approx. 10% of the time. Called dealership and said it is known issue with most denali brake lights. Was quoted to replace entire assembly $900. Each side for this known safety issue. This is a serious safety issue and known by GMC with no recalls available.
Passenger side tail light stops working occasionally. This affect's the brake light and night driving. It has stopped working up to a week at a time, but then starts working again. It might be weather related.
