Problems with 2015 GMC Yukon EXTERIOR LIGHTING

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).

I have now had my 3rd led light go out on my yukon xl 2015 the first was the passenger head light then the passenger tail light and now the driver tail light

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.

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 rear tail gave out twice and dealership or gmc won't over with. the dealership them self said it was faulty and they been having lots of problems with there inventory

Circuit boards in led tail lights failing. this results in sporadic functioning brake lights. the design of the bus bar in the tail light has resulted in creating weak spots in the bus bar that crack and unless replaced or repaired at substantial cost the brake lights may or may not function properly.

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 tail light stopped working. i had just over 37k miles on my vehicle when it happened, which is outside gm's warranty. called dealer and they told me its been a recurring problem with these vehicles, but no plans for gm to recall or repair part. was quoted over $700 to replace the part. its a faulty, cheap design and major safety issue. the car has not been in any accidents and been driven on streets and highways only. it looks brand new. here is just 1 forum of people discussing the same problem & a workaround fix. https://www.cargurus.com/cars/discussion-t53845_ds768963

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

Passenger side rear tail light led's stop working, had to replace the whole unit. not warrantied

We were stopped at a red light today by someone telling us our tail light was blinking and going out. our vehicle only has 65000 miles! i would think a led light should not go out yet. my vehicle sits under a carport when not in use. i have seen numerous complaints online for this same problem for same year model

2015 gmc yukon denali rear tail lights fail due to defected parts. gmc will not replace the failed parts which is a know safety issue. numerous complaints online with the gmc yukon 2015-2019 models.

Intermittent failed passenger tail light on a 2015 yukon, works occasionally. quoted 650$ to repair poorly manufactured led lights!

Passenger break light intermittently works. took to gmc they said there is no known issue which is a lie! hundreds of owners online having the same issues. they said they can't nail down the issue since there's clearly power there. they want me to buy a while tail light assembly! about 900 dollars for the same faulty part!

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.

Led brake lights go out quickly without any warning on the dashboard. multiple online complaints of same issue to the point that multiple businesses advertise about this specific fix. dealership wants $1500 for repair of both and despite online advertisements they deny this is a problem. this is a safety issue since whatever the cause it bypasses the dashboard alarm. you have to find out via accident, collision, or by receiving a ticket.

Driver side left brake light led poor quality, failed. turn signal works, brake light doesn't. leds are supposed to last longer than incandescent bulbs (and at the expensive price of $500+ to fix this each time it goes out people will be less apt to fix), but this is apparently a widespread problem from looking into it. there was no catalyst that set the problem off, just failed on its own.

Purchased my 2015 gmc yukon in june 2017. when i initially purchased the vehicle everything was fine. around may or june of 2018 the passenger side headlight was filled with condensation and i was quoted $1462 for labor and parts. mind you the vehicle had less than 50k miles on it. i sent a complaint to the corporate office and ended up paying $860 dollars to have it fixed. here it is now october and now both the brake lights are intermittently working. i just took the truck in for a recent recall for a steering issue. i'm not understanding why there are so many issues related to the lights. so i will now have to pay get the taillights fixed. there have been other issues not tested and i am currently flu at the point of reading this vehicle in.

Brake lights have gone off and on for the last two years before finally going out. dealership refused there was a problem while the vehicle was under warranty and now the repair will cost $1700

My tail lights go out every now and then. more in the summer than the winter. the break lights and turn signal still work great. i have looked online and it looks like a lot of people are having the same issue. its a safety issue having tail lights one minute and then not having tail lights. i asked gm months ago to do a recall and still haven't heard anything. this happens while it is in motion and stationary. we seen online that all the issue is, is a place that comes loose in the tail light and it only needs soldered together. we took the tail lights out and had a professional to solder it and they started working perfectly. they now are working part time again. for this to happen to multiple people i feel like it is an issue gm should fix. if it was rare i would understand if i had to buy new tail lights. but with multiple people having this issue will new lights not do the same?

Takata recall i believe that the tail light system of gmc yukons 2015 and any other year that share the same lighting system need to be recalled and fixed. my entire rear lighting system went out and i did not know it until someone started honking the horn at me and told me i had no lights. sometimes my lights work and sometimes it doesn't. most of the time it is only one light. we looked online for other people having this issue and it seems like many people have this same issue and the problem of it is a defect where a piece inside the light breaks and causes connection issues. i have seen (on youtube) many people fixing the issue by sauntering it together. this could be very dangerous. driving without any lights. it is also very costly to buy new lights that will eventually do the same thing. the issue happens all the time once it starts. the only time my rear lights work 100 percent of the time now is when it is cold outside. i have been told it is because the cold causes the plastic to swell and it must connect the piece inside the light .

Rear passenger brake light stopped working. internet searches indicate that it is a frequent problem with many complaints. most notable is the dealer cost to replace - $600 - $800 per fixture due to it being a sealed unit after warranty has expired. gm needs to fix this problem. a recall is definitely in order.

We had a taillight go out at 70,000 miles. the whole unit had to be replaced and we paid over $900 through a gmc dealer. then we had the other taillight go out at 88,000 miles. it cost $1000 to repair. we've recently reasearched the issue online and it seems to be extremely common on this specific vehicle and most people and reputable electricians have stated that it's a result of a faulty part in the unit.

The brake lights continuously work and then don't work. there is a malfunction with the brake lights in these cars. please report your issues so gm can stop robbing us.

The led brake light went out there seems too be faulty electrical and company knows it

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. here is just one of the links that describe this issue in detail: https://www.cargurus.com/cars/discussion-t53845_ds768963

Both brake lights are out. it's because of a defect in design. the metal bracket that holds the brake light leds is cracked and breaks the circuit, therefore the lights won't work. led lights should work for quite a long time. only way to fix it through the dealer is to replace the entire tail light assembly to the tune of approximately $1400 for both lights. it can be repaired by cutting the assembly open and soldering the crack in the led bracket. there are many instances of this being reported online. dealers deny encountering the problem. gmc is not addressing the issue. there are reported cases online where gmc yukon owners have of course had the repairs made within warranty with no cost but as soon as the warranty is out and the problem reoccurs, then the owner has to pay approximately $700 per light to replace the tail light assembly. this is a safety issue, no brake lights can cause serious wrecks and injury.

The right rear brake light and running light has gone out. appears to be a common problem. you can't replace the bulb like older cars. you need to replace the whole brake assembly for $700!!! gm knows about the common issue but is not covering it.

Rear tail/brake/turn lights randomly don't work. this issue is very common and complained about repeatedly on the internet. i have this issue with my left tail light.

Tl* the contact owns a 2015 gmc yukon. while driving 65 mph, the brake pedal was depressed, but the brake lights, tail lights, and the interior rear brake light flickered. the vehicle was taken to delano chevrolet buick gmc (600 1st ave, delano, ca 93215, 661-735-4974) to be diagnosed and repaired. the diagnosis results were unavailable. the manufacturer was not notified of the failure. the failure mileage was approximately 92,000.

Rear side tail lights intermittently stop working

The rear left light does not work consistently. i have been told by the dealer the whole light assembly will have to be replace at a cost of $800. the yukon is passed the 3 year warranty by a few months but below the 36000 miles. the extended warranty doesn't cover the light assembly either. go figure. this seems to be a common problem with the rear led lights on this gmc suv according to numerous web sites.

The rear left tail light has gone out, which is a common failure mode of this design. the entire tail light module must be replaced, pushing $1000 for a bad design. this needs to be recalled and replaced, as it is extremely affordable and a safety issue that gmc will not address.

Led brake lights went out. when i did a search on this problem, discovered that many others having the same problem with their yukons. dealers charging astronomical prices to fix. leds are supposed to last longer than regular bulbs. these light assemblies have a well known weak spot that causes them to go out. gmc has come up with an updated assembly. they should issue a recall and replace the original weak assemblies with the new ones.

Rear brake lights failed.

I was pulled over for no brake lights, officer told me he has the same vehicle and that he has the same problem. the brake lights come on and off when ever they want to. very very unsafe

Bought 2015 yukon in september 17, certified by dealer and june 18 i noticed rear light flickering on driver side. bought warranty for truck and it's not covered. dealer says 876$ for one new light . i have read online now where alot of complaints are being made for same issue. also have exterior black door panel flapping in the wind and dealer says that's not covered under warranty either. looks like i will be trading this truck in asap

Brake lights only work intermittently. this poses a safety hazard while driving and could cause a wreck. replacement is $800 per light, very cost prohibitive.

Both driver side and passenger side rear brake lights fail intermittently. at times it's just one side or the other, occasionally both sides fail at the same time. this is a 2015 vehicle with 40k miles and both lighting assembly's are failing.

Tail light malfunction intermittently. the tail lights and brake lights occasionally will go out and come back on randomly. gmc knows about the issue and replacements cost about $750 per unit which even these replacements have been known to fail within a year. the fact that this happens randomly and so intermittently this becomes a safety issue. i've had it in the shop and they said nothing was wrong because they were both working. i get home and they are not. is there a way to have gmc replace these via a safety recall?

Driver side brake led lighting is working intermittently. had it replaced under warranty. passenger side brake led lighting now working intermittently, new issue. have not had replaced yet due to outrageous cost($700) for fixture replacement. only 40,000 miles on vehicle obviously reflects a serious safety issue to financially strapped consumers.

Right tail light (only red light) doesn't work. reverse light works and signal light works all the time but red part doesn't. it works and then it doesn't. it does it randomly.

My vehicle is currently a little over 3 years old and i have owned the vehicle for the last 2.5 years. i am highly upset that the vehicle is in great condition, however the front driver side led strip in the head light is out. i purchased an extended warranty for almost $2000 when i bought the vehicle which they will not cover. i also have the back passenger tail light out and i am told that the whole panel needs replacing. a total for the led strip and back panel will cost close to $1900. why in the world is it that and led light is supposed to last 5x longer than a regular light, but it just goes out? that makes no sense. if the vehicle was 10 years old, that is one thing, but it being still on the new end, makes no sense. also, how does the whole back light panel just go out? and why do dealerships act like " oh well, there is nothing we can do!" gmc must be lowering their standards. had i known this vehicle would have these problems and no one seems to want to help, then i would have never bought it. something needs to be done, especially since i have spend the last 30 minutes reading a forum of a large amount of others having had the same issue.

Passenger side led taillight assembly is out with only 22,000 miles its past the 3 year warranty period. the dealership is asking approx $700 to replace/repair.

Tl* the contact owns a 2015 gmc yukon. while driving at an unknown speed, the brake lights failed to illuminate. there were no warning indicators illuminated. the vehicle was taken to an independent mechanic who diagnosed that the brake light assembly failed and needed replacement. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was 54,000. the vin was not available.

When the car is turned on, the passenger tail light assembly is malfunctioning and inconsistently work, but the turn signal and brake lights are working in the same assembly.

Led tail lights/brake lights not working due to bad circuit boards in the lamp housing when in motion or in park. gm says there is a upgrade kit but they made them where you can not get into them and fix them without replacing the whole unit which runs an average of $650 and up each. brake lights are a serious safety hazard if they do not work. i have been on many blog sites with hundreds of people experiencing the same issues on the same vehicle. gm should recall them and replace them with the upgrade kit because it is a manufacturing defect and a safety hazard on the road.

Rear tail light not working

Right brake light no longer works. unable to replace bulb and have to spend 775 on a new light housing since these are not serviceable lights

Brake light burnt out requiring the entire tail light lens to be replaced at a substantial and excessive cost over $800 for parts and labor. vehicle mileage under 36,000 miles.
