Both rear brake lights have failed
2015 GMC Yukon lights complaints
Page 7 of 10: complaints 161 to 190 of 269, newest first, as owners wrote them.
The LED tail lights are not working properly and cost 500 to replace it which is ridicoulous.
The brake lights work sometimes and then don't, this is a huge issue. If they stop working while driving this could kill me or another driver or someones passenger(s).
Tail brake light is out. Vehicle has not been in any type of accident.
I purchased a 2015 gmc yukon and am the second owner. Last week, my driver's side brake light went out. I noticed it while driving when someone behind me told me it was out. Six months ago, I replaced the passenger side brake light which cost $875 to fix (the entire light assembly must be replaced, not just a bulb). A little research online has proven that this seems to be a common problem for many other gmc yukon owners. Led lights are supposed to last the lifetime of the vehicle, but it would appear that something about the product is defective. This is simply outrageous and gmc knows that it is a problem.
Brake LED lights go out and on, sometimes one side works, then other times the other side goes out, and sometimes both brake lights do not work. Sometimes by banging the cover, it turns on and works, but then they go out.
Rear lights, tail lights stopped working. You cant just change the bulb. Being leds the whole piece has to be changed. Apparently this is a known issue and gm knows about it, yet theres been no recall??
All break lights stopped working at the same time on both sides of vehicle. Turn signal, back up lights, blinkers all still work. I was told the entire break light had to be replaced for a cost of apx 2k. It seems that this is a very common problem and the cost of repair is astronomical.
Right side /passenger brake lights failed. Dealer says it's a cracked electrical board. They said that they have seen tons of these and it's not under warranty. $1300 dealer repair estimate. This should be a recall issue.
Left rear tail light (LED) and break light failure. Not a bulb but the circuit failed. Bumper to bumper warranty would not cover bulbs, but this was not a bulb failure! I would like to appeal this denial
I have replaced the passenger side tailight and now the driver side tailight is not working. The turn signal and reverse light work but the red part of the light will work and then go out.
Rear parking/brake light went out. Dealer says the fix is $800 plus labor to fix.
My gmc youkon denali has brake lights that are known to dealers to fail. Yet there is not a recall. I looked on the inter net and saw that there has been this problem since 2015 to 2018. Because of a joint that was soldered instead of a wire. I know why when I brought it in for recall that the service man looked at my stop lights.
The LED brake light went out there seems too be faulty electrical and company knows it
Within the last year on my 2015 my AC compressor has gone out, radio screen quit working, brake pump/booster faulty, and now rear brake light quit working. All seem to be very common in this year model. My car has less than 70000 miles on it!! Gm is either doing a crappy job on their $60000 vehicles or a recall needs to be done.
Rear break tailights do not work at all times. Most of the time they require tapping on the taillight to get them to light the tail light. Not a bulb issue and seems to be a common problem with all yukon's of this make. Very frustrating to have them work inconsistently . Sometimes one light out and sometimes both.
Driver side taillights are broken. Passenger side taillights are failing now. Neither taillights nor break lights are functioning properly on the driver side and the tail lights are starting to fail on the passenger side
Passenger side brake and tail LED strip light short and goes out and stops working. Will work sometimes when back hatch shuts and jars it or I hit a bump. Dealership says light it out and needs replacing. Not sure why the light still comes on when jarred. Have extended warranty that was supposed to cover all this especially being electrical. Seems to be on going problem
I have 47,000 miles on my yukon slt. I replaced the high pressure fuel pump about two weeks ago for a price of $1,400. Now my driver side brake light went out. Dealer is telling me nearly $800 to fix. I paid good money for this car and have had nothing but problems.
Left back taillight defective. It was replaced by gmc in 2017 under warranty (below 36,000 miles) now at 44000 it failed again. Lots and lots of people posting the same issue online. Bad design or just plain bad quality. See one of the posts here: https://www.cargurus.com/cars/discussion-t53845_ds768963 see video here explaining issue on how internal board cracks and causes the issue: https://www.youtube.com/watch?v=nnldjpymdzc another video: https://www.youtube.com/watch?v=2ljxuqme3tu dealer charges $844 parts and labor to replace, this is a known issue for gmc, this needs to be a recall. The issue is so well know that there are people on ebay making a business to repair it. A simple type in ebay yukon tail light will show multiple links.
Brake light is not working on passenger side. Went to replace bulb and found out that one has to replace the entire taillight ensemble which is $700-800. It is sad that something important to safety like a brake light has to cost that much to replace. I researched and found this tends to be a common problem. So much for LED lights--this is also poor engineering!
Tl* the contact owns a 2015 gmc yukon. The contact stated that the LED tail lights burned out prematurely. The contact called [xxx] at 817‑264‑7746 (located at 501 tx-114, grapevine, tx 76051) and was informed that the tail light was a sealed unit that needed to be replaced as a whole. The contact stated that the repair was too costly for a simple burned out bulb. The contact called it a design flaw. The manufacturer was made aware of the failure, stated that nothing could be done, and offered the contact a small discount for an oil change. The vehicle was not repaired. The failure mileage was approximately 66,000. The VIN was not provided. *dt information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
Brake lights for passenger rear lamp assembly is not working. This is the second time within 25 months that this has happened. The entire lamp assembly needs to be replaced at a cost of $600+. The vehicle has less than 49,000 miles, and it is no longer covered under warranty. Online forums indicate that this is a common problem with the brake lights in the lamp assemblies. It appears the circuit boards for the LED brake lights are breaking.
The LED rear brake lights aren't working.
Passenger side rear brake light was working intermittently and now has stopped working all together. The brake light unit is a sealed unit that can not be serviced, it must be replaced entirely. Very common problem on this model due to a faulty brake light assembly. Failure of brake lights puts the safety of my family in jeopardy.
Tail and brake lights failed. Upon inspection it was found that the conductive plate between the leds had cracked/broken in both assemblies.
The brake lights have gone out with only 42000 miles on it. I have read on message boards across the nation this is a major problem. Dealer wants 800 to fix it.
All LED lights have went out on right side, as well as break lights. This is a know issue to gmc, and yet they will not correct it. My quote to have it fixed was 2493.00 from local dealership. That is crazy. Led lights should last a whole lot longer than this. Also condensation is in the front headlight with no holes or cracks. If this happens with house windows, they are replaced by the manufacturer. There are so many complaints, I will also be contacting the better business bureau. Gmc knows there is a problem with these models.
Taillights works inconsistent no brake lights took to dealer they said the both lights need to be replaced and my warranty doesn't cover it they said these vehicles are known for having this problem need for help with this
We own a 2015 gmc yukon with only 51,000 miles on it. The rear taillights are both intermittent. Sometimes they work, sometimes they don't. I recently took the vehicle into the dealership for service and they said replacement of the entire light was the only way to fix the issue. They acknowledged that this is a known issue and that they have serviced many vehicles with the same issue. The service person advised that there is a circuit that over time breaks and the connection becomes loose. When the metal touches and a complete circuit is made, the light will turn on. When it doesn't touch (faulty), the taillight and brake lights will not illuminate. This is a major safety hazard. A simple internet search shows that this issue is very common and gm doesn't appear to be doing anything to address it. Because it involves the brake lights, this is very concerning. Not to mention, that a replacement is $800. I have already spent $800 for one side, now the other side is out as well. I feel that this should be a recall issue since it's an obvious safety issue that is caused by faulty parts.
