Brake lights - left brake light works intermittently, and often does not work. 3rd brake light (top center) has quit working. Both are issues with cracks in the circuit board, which googling has shown to be a known issue. Faulty, poorly designed or constructed parts!
2015 GMC Yukon XL lights complaints
Page 2 of 6: complaints 11 to 40 of 140, newest first, as owners wrote them.
Breaks are faulty, lights continue to go out in the rear after only a year after purchase. I’ve read other complaints about these issues. could be wiring or electrical issue with the breaks. Engine sounds like a plane is about to take off, has had starting problems. Overall horrible vehicle. There are a lot of problems with the vehicle, the lights are extremely dangerous as person behind would not know if I’m stopping when they fail to work and can cause a serious accident. Engine is a major concern as well.
Driver side brake lights don't work again. This will be the 3rd time that I know of that this piece of equipment has been changed out.
LED Brake Lights fail due to design error typically on both side of the vehicle. I have found multiple reports of a failure on a circuit board that was poorly designed. A copper tracing is very narrow and fractures due to vibration resulting in Brake Light failure. Because the entire module must be replaced the repair costs $800-$900 per side.
Tail lights are not functioning properly. N182180270 was issued due to very common issue but no recall. The special adjustment only covers up to 72,000 miles. I now have 106,000 so not covered? Serious safety issue if brake lights are malfunctioning and GM aware of issue. If technician checking lights and they are intermittently working, then I drive away from dealer and they intermittently no longer work, that is a serious safety issue and a recall should happen. I took my vehicle in for an oil change and on the drive to have serviced I was told by my wife driving behind me that the right rear brake light wasn’t working. I asked tech to check. Technician confirmed but states left isn’t working either. Yet on drive to drop the vehicle for oil change the left was working. And we have a time stamped photo as proof(attached). I had someone tell me right rear brake light was out a couple of years ago but when I had it checked, all were on. So when are they working? When are they not working? And that is why a recall should be issued. correct a faulty design. These aren’t an easy fix of replacing a bulb. The whole unit has to be replaced at $700+ each. How many people are out there driving with these intermittent brake lights? We periodically check our lights to ensure working. But if these lights are on/off intermittently, that does very little good. Scary!
The contact owns a 2015 gmc yukon xl. The contact stated that while driving at an undisclosed speed, the contact was alerted by her husband who was driving behind the vehicle, that the rear tail lights were inoperable. The contact was also alerted by other drivers that the rear tail lights were not functioning as needed. The vehicle was taken to sierra blanca motor co. (304 us-70, ruidoso, nm 88345, (855) 707-6474) to be repaired under the federal safety agency campaign number: 19v645000 (service brakes, hydraulic). The technician also inspected the lights and stated in the diagnostic report that all lights were working at the time of inspection. The vehicle was taken to an unknown dealer for the failure however, the second dealer was unable to duplicate the failure. The contact then had her friend, who was a retired authorized gmc technician, inspected the taillights and duplicated the failure. The vehicle was then taken back to sierra blanca motor co. However, the service advisor inspected the tail lights but offered no assistance. The manufacturer was made aware of the failure and informed the contact that they would check with the dealer to see if they could assist with the failure. The manufacturer later informed the contact that they would offer a 25% discount for each light to be replaced. The vehicle was not repaired. The failure mileage was 61,835.
Rear LED tail lights failing. 1 has been replaced already, second, opposite side is now failing.
Passenger rear brake light is out. All LED lights will not light up with running lights on or the brake depressed
Rear brake/taillight assembly not working consistently in motion.
Left rear light assembly intermittent open circuit. Wiring checks okay. Good power and grounds. Noted that the lamp housing has evidence of corrosion at the base of the main connector. The housing is a sealed unit (no serviceable parts) so the nature assembly needs to be replaced. I am a 37+year a.s.e. Master technician and state of michigan master technician so I am well seasoned at proper auto/light truck electrical diagnosis. The light will go out while siting still and/or in motion. This is a safety concern for obvious reasons.
One of the break lights is out. They have made the brake lights in such a way that you can no longer just replace the bulbs but have to replace the entire unit at a cost of $885. There is a design flaw in the 2015 and 2016 models that causes the brake lights to fail. Gmc is aware of it and did extend warranty coverage so that if you are "lucky" enough to have them fail with less than 72,000 on your vehicle they will replace them at no cost but after that they will not. They know the product and it should be recalled. It is a safety issue for people to drive around without brake lights because it costs nearly $900 a piece to replace them! Perhaps they shouldn't have turned what used to be an cheap, easy thing to fix on your own into a $900 repair in the first place. Now that they have they should at least stand behind the product.
Led brake lamp went out at 42k miles, but gm requires replacement of entire tail lamp assembly at exponential cost.
The left LED tail light would go out and then come back on. This has been happening for over a year now. Police stopped me twice but thankfully, did not give me a ticket. Had it repaired 2 or 3 times. It might last a day or two and then goes out again. Apparently, there is a thin metal piece that is sorted together that keeps breaking. The right one has started doing it too. I was over the mileage for the recall. Can't afford the $1600 or so it would cost for new improved tail lights. What does mileage have to do with repairing a defect in the products used in the tail light? I am constantly afraid someone will rear end me since the light doesn't work.
2015 rear brake lights work intermittently and need to be replaced or repaired. Gmc know there are numerous complaints about this problem and have done nothing. Huge safety issue!!
Took my certified pre-owned 2015 yukon xl into dealer while still under warranty with intermittent failure in both tail lamps (the red part for brake and tail lamp function goes out; turn signal still works). Condition was not noted on my service ticket since the tail lamps was working fine at the time. Warranty expired, passenger tail lamp went out completely and both dealer and a call to gmc told me that they wouldn't assist in spite of my attempt to address while under warranty. Needed tail lamp to pass state inspection and return my wife and four kids safely to the road, so I had to pay. As I walked out of the dealership to retrieve my vehicle after the $400 passenger tail lamp replacement, I found the driver side tail lamp to be inoperable, even though it had just passed the state inspection 20 min prior. I showed the service advisor and spoke to service manager. They both agreed that the tail lamp issue is wide-spread, unsafe, and a major quality issue, but they were bound by gmc policies. Yes, gmc extended the warranty for these tail lamps, but I bought my vehicle as preowned certified with 68k miles. Special part warranty went to 70k and my certified warranty went to 80k. I did my part and took the vehicle in as soon as the problem arose, yet here I am holding an $800 bag of broken tail lamps. Horrendous quality issue that is a major safety issue for these vehicles. It is time to issue the recall!!!
Major safety issues with this vehicle. Another 2015 yukon with no tail or stop lights. I'm over millage on special recall. There should be no time/millage issue on this. Seat belts lock up. Brakes are either good or mussy whenever they want to be. Hard to stop the vehicle. Also when I first purchased the vehicle it would completely die (no lights motor died, no power steering, no air bags, no radio nothing at all on the x-way at 70 MPH) and the dealer could not repair it! Rust on frame rails. (and more).
My passenger side tail light assembly need to be replaced as the brake lights are not working. This has become a common problem as evidenced by the number of complaints filed on your site for the same issue. Lack of properly functioning tail lights is a major safety concern and a recall should be issued.
The rear passenger & driver side brake lights just randomly stopped working. Not a bulb issue as it is the LED panel of lights. The back-up bulb still works, but the LED brake lights don't. Led lights should last years. Dealership says it happens a lot to these vehicles, and I have to buy a whole new unit for each side. This is a huge safety issue - break lights failing due to poor wiring. Again not a replaceable bulb issue, it is due to a wiring issue within the LED lighting unit itself.
Tl* the contact owns a 2015 gmc yukon xl. The contact stated that while depressing the brake pedal the rear brake taillights failed to illuminate. The vehicle was taken to keweenaw buick gmc located at 608 quincy st, hancock, mi 49930, to be diagnosed. The contact was informed that the rear brake lights were defective and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but provided no assistance. The failure mileage was 102,000.
The brake light is not working. All other functions in the assembly are fine. Reverse and turn signal, no brake indication. It does not activate a warning on the dash for the brake light failure. This happens 24/7... This should not occur with an item priced at over $700.00 to replace.
Brake lights intermittently not illuminating and going out. Both driver and passenger brake lights.
We purchased this vehicle in february 2019. Less than a year later our right tail light started going out randomly. Then it completely would not work. We pay for an extended warranty, but it didn't cover it. Then shortly after the left tail light did the same thing. We currently have 84k miles on our vehicle. Due to negligence, and a dishonest company (gmc), this military family is down to 1 vehicle as we cannot afford the almost $2k it will cost to fix the tail lights. This is not due to anything we did, it has everything to do with fault brake lights that gmc will not fix past 72k miles which is disgusting and a slap in the face to people who give them their hard earned money. I have done extensive research and this is a very common problem in these vehicles. There are dozens of blogs, posts, websites, etc of customers complaining of this issue and gmc not helping past 72k miles which is a horrible explanation and is not helpful to most of us. We have already had to pay out of pocket for things that have broken (normal wear and tear which is understandable) that wasn't covered under our platinum extended warranty. However, gmc needs to do the right thing especially for our men and women in uniform, and fix what their company has deemed as faulty past 72k miles!!!
My 2015 gmc yukon xl brake lights intermittently don't work from the day I purchased it and cant the dealer to fix the problem.
Break light intermittently illuminates on driver's side. Received letter from gmc dated december 2019, "intended to make you aware that some 2015 model year gmc yukon xl vehicles may have a condition where the brake lights intermittently do not illuminate". The would repair it with no cost only if this would have occurred within 6 year of the date your vehicle was originally placed in service or 72,000 miles. Of course, we are way above that. Dealer quoted $800 cost repair.
Both tail lights (brake lights and running lights in red) stop working with no warning to the driver. Third brake light does continue to work. This is noticed when parked and when in motion. This is a safety issue for other drivers crashing into our vehicle because they do not know that we are braking. A friend had to point this out to us in the school pickup line. First noticed on 2/13/20. Had to buy two new taillight assemblies and install.
I bought this yukon and the next day a gentleman that was riding behind me almost hit me he came to the side of me and said my tail light is not working they come on when they want to in and out and sometimes not at all this is a serious problem its happening to all of the newer models and they are 800 for a new tail light there needs to be a recall on the tail lights something is wrong with the LED strip in them this is going to cause someone to get hurt I have 4 small children and I do not need to get into a crash and I do not need to spend 1600 plus to get new ones.
No brake light in both rear lighting assemblies. Started with the passenger side and now the drivers side. Gmc issued a letter in december 2019 stating they'd pay for repairs if vehicle is less than 6 years or 75,000 miles which ever comes first. We'll I'm over on both. Gmpp extended warranty doesn't cover this repair. Spend $75k for this truck and now this.
Both tail lights stopped working on the freeway during my trip to san diego from phoenix. About halfway here one tail light went out in about 20 miles later the other one stopped working. I know this because a friend was following me.I called the dealership, he stated that the tail lights are on national backorder and won't be in for a week plus. Now I am driving around california with no brake lights.. I only have 48,000 miles on this SUV, each tail light is $760 the only way to repair this is to replace them. Thank you gm I will be forwarding you my ticket..
Gmc recently advised us that the tailgate lights have had problems where they "intermittently" do not illuminate. We have had this issue for quite sometime where drivers cannot see our tailgate lights when the problem occurs. Because it has been intermittent, it has been very hard for the shop to diagnose as when they get it and it is on, they can't figure out what is wrong with it. Since we received the letter from gmc, we have been into the dealership to get it resolved, but they will not do it because our miles are over. I have told them that they know its an issue and that it is intermittent and when people take it into the shop to get it diagnose, its a hit and miss. I have now seen over a dozen other gmc's on the road with the same issue. Last week, while traveling with kids to a soccer tournament, both weren't working at night and we were pulled over. I fortunately had the letter in the car and showed it to him. He gave me a warning and advised that it is very difficult for cars to see at night when there are no tailgates on and that gmc had better get this resolved. I have made two requests with gmc and they have denied the request. I even told them that I would cost share if we meet in the middle and they would not. They know this is an issue, yet they aren't willing to extend the warranty or make it a recall. This is very dangerous and could cause a lot of accidents with gmc models nationwide. I hope that this is brought to someone's attention and that gmc is encouraged to get this resolved with 2015 yukon xl suvs and that we and many others are able to get their tailgates replaced.
Tl* the contact owns a 2015 gmc yukon xl. The contact stated that while driving at 45 MPH, a bystander informed the contact that the rear external brake lights were inoperable. The contact exited the vehicle and confirmed that the taillamps were inoperable. There was no warning lights illuminated. The vehicle was taken to gunn buick gmc located at (16440 interstate 35 frontage rd, selma, tx 78154 (866) 468-6484) to be diagnosed. The contact was informed that the taillamp assemblies were defective and needed to be replaced. The vehicle was not repaired. The failure was intermittent. The manufacturer was not notified of the failure. The approximate failure mileage was 80,000.*dt
