Problems with 2015 GMC Yukon EXTERIOR LIGHTING

For the past 6 months i had been getting reports that my passenger side tail light wasn't working- when we checked it it was... finally someone told me it goes on and off. my yukon was going into the dealership for the power steering recall and i asked them to check. they replaced the whole light at $800!!! a quick internet search shows this is a common problem.

Passenger side brake light stopped working

Tail lights intermittently work. there is no way to replace a bulb, and gmc has a replacement that fixes the problem, but it has not been recalled to fix the issue.

The most disturbing concern is the fact that i lost my brakes as a result of a known problem that gm has even recognized relating to a faulty vacuum booster pump. i incurred a $500 repair bill despite gm's acknowledgement of the problem and willingness to pay for cars with less than 70000 miles. unfortunately, mine was over the allowable mileage. additionally, i am looking at a $1500 repair bill for a sealed headlight replacement and another $300 bill for a side detection system ( lane departure warning). gm made a poor car that is unsafe and is not properly addressing the problem.

The tail lights/ brake lights the cheaply made and have read of hundreds of people with this same issue i'm having that the circuit breaks and they stop working. this is a serious safety issue

The led tail lights are not working properly and cost 500 to replace it which is ridicoulous.

Both led taillights failed within one month on a truck with less than 25000 miles.

Brake and tail lights go out intermittently while driving. i've been stopped multiple times on road with other drivers telling me. i also have several friends with same model telling me this happened to them.

Rear tail light is no longer working. lights are led, so the entire tail light needs to be replaced.

Tl* the contact owns a 2015 gmc yukon. the contact stated that there was an intermittent electrical failure that caused the rear tail lights to short out. in addition, on several occasions, other motorists alerted the contact that either one or both tail lights were out. gettel chevrolet buick gmc (1901 tamiami trail, punta gorda, fl 33950, (941) 347-6817) was notified, but could not duplicate the failure. the failure continued intermittently. the contact purchased the vehicle from vision buick gmc (800 panorama trail s, rochester, ny 14625, (585) 200-3905) and they scheduled an appointment for diagnostic testing. the manufacturer had not issued an electrical system recall to provide a permanent remedy. the manufacturer provided a case number and was to follow-up with the dealer and the contact. the approximate failure mileage was 48,000.

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.

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??

Both led tail light fixtures went out at once, both non functioning. have to replace both fixtures costing over $1400 from a gm dealership.

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

Faulty rear brake lights. the right led module failed, and was replaced. then the left led module failed about a year later. now the replaced right led module has failed for a second time! each repair is approx $650.00 for a 'do it myself' repair. these led modules should last for the life of the vehicle and not fail. widely noted as being a defective design. gm should redesign and make good on repairs beyond the standard warranty for those of us that are out of pocket.

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.

The rear tail lights work periodically. i've already replaced the left side and now the right side has went out. cost is $750 to replace. i am currently having to wait on a tail light because they are backordered due to so many others having same problem (according to dealer). it will work periodically at first but if this is like the previous, it will eventually quit working all together. sometime the bottom half is lit but not the whole lamp. dealer couldn't tell me if they had fixed the problem or if i will be getting another faulty part.

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.

Rear parking/brake light went out. dealer says the fix is $800 plus labor to fix.

Both rear brake lights have failed

My rear passenger side tail light randomly works. no rhyme nor reason. we noticed this after bcm was replaced.

Tail light- brake light not working. passenger side tail light does not work.

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 .

Left taillight went out at around 82,000 miles, first flickered for a few months, then went completely out. within one week, the right taillight went completely out also.

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.

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.

Shortage in passenger side tail light. dealership quoted $800 to replace complete light.

Rear faulty brake lights both sides. quoted 1800 to replace. with a quick search for replacement/fix options i found a single individual that has repaired over 2000 of them. there are many more out there. this seems to be an issue with a high percentage of this make and model and gm acknowledged it by replacing the cope the 2 years later but has refused to recall this. it's an absolute safety hazard that seems to be ignored by gm

Tail light lighting strip spontaneously malfunctioned and stopped working. vehicle has no light and no brake lighting which could have resulted in auto accident. within a month the headlight has burned out resulting in a blinker malfunction. vehicle was on highway when both lights malfunctioned

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.

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!

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.

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

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.

Tail led lights and brake lights stopped working then start working partially then back to not working, went to have them replaced and it cost $1500.00 and then 6 months later back to partial working tail led lights and brake light then a small strip of them working then nothing at all then back to working then back to no light permanently again!!

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). *tr

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.

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.

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.

Our 2015 gmc yukon denali has had the rear tail lights intermittently stop working for some time now. we even got pulled over by the police and were issued a fix it ticket!

Brake lights give out on both sides and are very expensive to repair

This is the second taillight to fail. the passenger side failed at 35,500 miles in october 2018. the driver side has now failed at 39,000 miles and 4 months later. these parts cost $800 each to replace. a major repair cost on a vehicle with only this much mileage. a design problem obviously exists and this problem is a safety hazard!!! just waiting for a crash to happen to start a class action law suite.

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

Both tail lights work intermittently. i have been stopped by other drivers on several occasions to tell me that one of my tail lights was not working. both lights are effected, but not usually at the same time, so i at least have one working light at a time. this has been happening since i purchased the vehicle from the dealership used car lot on 01/23/2019 whether i am sitting still or driving down the road. when the light goes off, you can hit the light assembly with your hand and it will momentarily come back on.

Where to start, it seems gmc yukon xl has been having a lot of issues with its models 2015-up. imagine driving at night and all of a sudden one brake light goes out then a few moments later the other as well. i have read multiple complaints about this issue on going with gmc but no response to resolve the issue. how can three year old suv lose not one but both break lights and your stuck out of town trying to fix or find a resolve. you can't replace the bulb but need to replace the whole assembly, god forbid i would of been driving or some hit me due to both break lights going out. this issue with the brake lights for the gmc needs to be addressed and fixed. you spend so much money on what you thought was a great vehicle only to realize you purchased a lemon instead.

My taillight stoped working. when i turn my headlights on it wont turn on or when i apply my brakes. i searched the internet(facebook and fourm sites) and found thousand and thousand of people having the same issues. the brake light/running light is not a light bulb like most cars that you can just replace when it goes out. its led.so you have to replace the whole entire light assembly and it was over $800. led are supposed to have a long life before they go out.... this is only a 2015 i mean come on. so i had to drive in the dark and during this rain storm on freeway and regular streets with no brake or running lights which i s extremely dangerous. this is a family vehicle i drive my kids in this car. this cant keep happening. i also read that multiple people said once they bought a new assembly it went out again and stopped working down the road. this is insane.

I purchased my 2015 yukon in 8/2016 and in the beginning of 2017 the tail light on the right side burnt out the brake light did not work during the day but at night it would work . i took it to the dealership and they told me the led lamp had gone and needed to be replace . i came find out this lamp is all one part and the cost for a supposedly is over $600 just the lamp . so i had to buy the lamp and replaced it myself but they asked me for the core . so this was in 2917 and now two years later the same light that brought brand new in 2017 is out again and i'm having to spend another 600 to replace it again. i feel something should be done to help the consumer because gm does not care about this and how it affects the vonsur . can something be done ?
