Exterior lighting issues. Rear running lights not working. Rear break lights are not working. Right side blinker not working in front head lamp or rear lighting fixture. When the vehicle is hooked to the computer at a gm dealership the computer will not show what the issue is. This is a safety issue as I can not safety drive the vehicle at night due to no lights in the rear of the vehicle nor during the day without break lights.
2015 GMC Yukon XL lights complaints
Page 5 of 6: complaints 101 to 130 of 140, newest first, as owners wrote them.
Left brake light working intermittently and then went out completely. Right brake light followed immediately after. Dealer wants 1550.00 to replace
My rear tail light went out 1 month after warranty ended. This happens to all many autos in this class. Please do something or I will stop buying gmc autos.
My passenger brake light intermittently does not work. This is clearly a common problem with this make and model. Here is an example of one of many forums : https://www.cargurus.com/cars/discussion-t53845_ds768963 this is a safety problem and gmc should offer a recall for their faulty LED lights.
This is the second complaint that I have made to the federal safety agency. The first time, the vehicle was spontaneously turning off and shutting down during backing in and turns causing a safety issue. This resulted in a recall, and a "software update" that was done twice to correct the issue. Right and back passenger lights began to blink on and off and water gets into the brake light. The dealer told me this was m issue. This time the 4wd service light came and the car appeared to be stuck in "4wd low" making it "drag" at a reduced speed when driving. Also, the "service trailer brake" light came on repeatedly. I have never used the trailer brake. I took it into an authorized dealer, sellers gmc in farmington hills, mi. They told me I needed a new "module", so I paid to have that done. Within one day the same service lights came on again. "service 4 wd" and "service trailer brake." I immediately took the vehicle back and am now being told it needs another software update and a new trailer brake transfer switch. Quite frankly, I believe that this model has significant, unaddressed computer software issues and the dealer does not know who to fix it. The car is unsafe because it spontaneously stops working appropriately during driving. The concerns have been various and always seem to affect steering, when turning or backing in. I am being charged for various control panels and modules. I am requesting that this concern gets addressed before there is a serious injury. I would like my vehicle fixed and returned to a safe condition. I was never told upon purchase, that this model would require so many "software" updates to remain safe. This should not be a burden placed on a consumer for a vehicle to operate safely. This is dangerous.
I am extremely disappointed at general motors at the lack of quality design in the rear tail light LED assembly. My wife and I have owned gmc vehicles all our lives and have never been more dissatisfied with the lack of quality design in the rear tail light LED design and design life. In conducting research the last few days, this has been a consistent and well documented design flaw that gm still has not addressed. Led lighting when design properly is supposed to function properly much longer than standard bulb incandescent lighting. This creates a safety issue with our vehicle because we have no rear lighting and then we receive the estimate from our dealer "royal buick gmc" at over $1500. Obviously, I am feeling such frustration because my rear tail light assembly's are not functioning properly on my wife's **** gmc yukon xl slt. Of course after the initial warranty has expired. Coincidence, or not very displeased? I would like someone contact me at ***-***-**** or by email and offer assistance to replace these tail light assemblies due to the quality or lack there of, in the part. **sincerely disgruntled gm customer!!!
The brake lights on my 2015 gmc yukon xl have both gone out. I have been pulled over and questioned about it several times by my local law enforcement. I believe the manufacturer state that they have a life of 40,000 hours of continuous use but, only function for a fraction of this amount & they are $600-700 to replace.
There is a known electrical issue with the yukon tail lights. The enclosed LED running lights and brake lights will go out and not operate. This is a huge safety concern as there is no brake light that will illuminate and no running light. Both of my tail lights have gone out on my vehicle. During a record check I have learned that this is a common problem with the yukon's. Gmc has failed to take action about the known problem. The problem is persistent while being stopped and driving. Secondly the braking vacuum system will go out unexpectedly. This causes the assisted brakes to fail causing the braking system not to take affect and stop the vehicle properly. This is a huge safety concern as you will not be able to safely stop your vehicle in a timely manner and will cause several accidents. I noticed that the brakes had filled while being stopped at a stoplight and also while being mobile and driving.
We purchased this vehicle on 11.21.18 and the brake lights intermittently don't work. They were working at the time we drove it off the lot. The bulbs were tested by our mechanic and he stated that the gmc yukon of this year are known to have major problems with the brake light housing units on the rear of the vehicle. The electrical board associated with it has issues the mechanic stated. I reviewed many post online and wonder why this isn't a required recall. To me this is a major safety concern and we bought this vehicle to transport my kids and wife. I'd like this to be considered a recall immediately.
Rear tail lights intermittently working. Problem occurs when stationary or moving, can change from functioning to not functioning and back while in motion.
My passenger front light cover is acquiring condensation which makes the lights go off and on, and my driver side brake light works only intermittently. My insurance or warranty won't cover anything to fix these light issues. These issues started about may 2018. We weren't in a wreck or sustained any damages that would have LED to these issues. I have talked to two other owners of the same make/model/year vehicle and we all have safety issues that are not being resolved by gm vwarranties. I want to see gm issue recalls and accept complete financial responsibility for repairs. I would also like to see the rear lighting system redesigned so the components are not dependent on each other. My brake light went out and instead of being able to replace a bulb the entire unit has to be replaced at $1700.00 that we just simply do not have.
Brake lights work intermittently. The problem is not with the LED but with the poor quality of the controller board. Both of my tail lights have encountered this issue in the last 4 months and they are very expensive to replace. The part alone is over $ 900.00. I have talked to a couple of dealers about this and they are a frequent problem, and one dealer specified that he has sold 4 replacement units in the last 24 hours. This indicates that the tail light assembly is very poor quality and can be a safety hazard as there is no way to tell that your brake light isn't working unless someone tells you.
Issues with back LED tail lamps not working. I have seen many issues with people having the same problem.
My drivers side tail light just works intermittently when I am out on the road driving.
My right rear tail light works on and off for about a year . I have 41,000 miles on my car and now the left tail light goes in and out also so I potentially could have two brake lights out at the same time. I've seen several of the same car is on the road with the same problem gmc denies the problem and charges $800 per tail light to fix it's a huge safety concern and I don't feel like my family is safe and I don't think we should be liable for their faulty light equipment. They won't recognize they are responsible for the issue it's completely unacceptable and a huge safety concern. When looking up the problem online there are hundreds of people who are having the same issue with the same model car.
Led taillights and brake lights work intermittently on both driver and passanger side. Problem has been long term and appears to be failing more frequently now.
Front right LED daylight light is out. Car is out of warranty, and part is approximately $750 to replace, vice just a bulb swap. Car has about 90k miles on it. Led daylight is not able to be repaired. I believe it's referred to as drl. Dealership will not replace in warranty, because car is out of warranty - and replacement for a light is over $700....absolutely unacceptable and unsustainable. Especially since this model is a 2015 model. Over the life of this vehicle, how many times am I expected to replace a $750 LED housing?
Multiple complaints have been filled with gmc about their poor brake design on their 2015- 2019 yukons the circuit breaks and the tail light assembly quits working. Yukon says they have not heard of such complaints. And will not recall their poor assembly design.
Drivers side taillight stopped working. Signal still operating.
Both brake lights failed within days of each other. The failure was the same as indicated here: https://www.cargurus.com/cars/discussion-t53845_ds768963 . I have pictures of the failed piece.
Bad LED brake lights: we purchased our gmc yukon xl 2015 in may 2016. Since then we have had to replace both brake lights(1 after a year-march 2017 and the 2nd after 2 years-aug 2018) and have had the vehicle only 2 years. They are LED lights so not a cheap repair. Quoted cost $750-$2000. So far, our warranty has covered the repairs but once warranty is off, it will cost too much to repair and is not safe to drive without repairing! We have had many vehicles over the years and have only replaced brake lights 2-3 times and for less than $25 each time. This appears to be a bad design or faulty parts by gmc. One of the failures was due to internal short in the LED module. We would like gmc to resolve the faulty parts and recall the part and fully replace our brake lights with reliable lights vs lights that only last a year. Thank you!
Right tail light began to not work last fall. I went to have it checked then it was working fine. Went in for about a month. Sometimes it worked then it wasn't. Almost like it had a short. Eventually had to replace whole system not just a bulb. Now almost one year later the same thing is happening on the left side. This is a $1,000 item. I have owned cars for ten years and never had to replace a light. Read online that there are many issues with these tail lights.
2015 yukon brake light needs recall" does not work ...it's a known issue and an expensive fix. Need help this is
Rear tail light failed, was replaced and failed again 2 months later. Very expensive repair for continued malfunction. No breaklights, no turn signal, no warning. Discovered by other drivers notifying me on the road.
Passenger side taillight is not working correctly. Signal works, but the brake light and running light does not work. I got this vehicle in april 2014, taillight started going out exactly 2 years after purchase. Took vehicle to dealership and they said it would be about $650 to replace the whole taillight and that it was not repairable. The taillight is still out and I refuse to replace it since I believe this is a defect. I have heard many other similar stories of other yukons with this same problem. When in cold weather (under 60 degrees f) the light used to flicker but not stay on. It has been hot most of this year so I do not know if this is still true.
The right & left rear brake lights and running lights intermedatly fail. I have had my right one fail, my left one fail and on one occasion both failed (right, left, brake & running lights at night time. I had people flagging me down at intersections and had friends text me while they observed me drive away. The lights would somehow begin to function properly but it is unknown how long they would remain non functioning. This is an enormous safety concern! It is unbelievable that gm has not recalled the poorly manufactured LED lights on their vehicles. The fact that they function properly one day and then don't function the next is unacceptable. My initial quote from gm to have the light replaced was $1,600 for both lights. Riduclous cost for a four year old $60k + vehicle. It should be noted that the top /third brake light seemed to function at all times or was never reported to me as not functioning. I don't have photos of the inoperable rear brake lights. Both
The suburban is not fully 3 years old and having issues with the tail lights. It is 1700.00 to repair tail lights. That is crazy. The lights go on and off. Days it works days it doesn't. I have had 2 warnings to get them fixed. First it was just the right one and the officer noticed that the left keep going on and off.
Rear brake/tail lights are not working all the time. They go in and out.
Rear passenger taillight is out. It appears to be a common issue but dealership and gm customer care will not stand behind their product. Typical response "vehicle is out of warranty now". Now I have to pay $600+ on a part plus labor. .
The drivers side rear tail light stopped working. Checked multiple forums and this issue continues to be a chronic issue for owners of this vehicle.
