Problems with 2015 GMC Yukon EXTERIOR LIGHTING

The rear led brake lights are intermittently not working. it appears to be a bad connection or faulty light board inside the housing. when the temperature gets hot, the brake lights stop working. it can happen at any time, when driving or parked. not having break lights on a vehicle is extremely dangerous. there is not a way to change the bulbs or board without changing the entire light housing. after a quick google search, this is a serious safety problem affecting a huge number of people with the same exact issue. thousands of people are experiencing the same problem and it appears to be a manufacturing known issue that the dearlerahips are cashing in on.

Rear tail light is out and dealership wants to charge $900 to replace the entire assembly. this vehicle is 3 years old. there is absolutely no reason an led bulb would or should burn out this fast nor should the entire assembly be replaced. gm should be required to recall or replace just the bulbs at cost.

Right rear taillight works intermittently. it is an led assembly, no bulbs can be replaced. only way to repair is to replace total assembly at cost od well over $650.00. this is a design or product flaw that gm is aware of and should be replace under warranty. they deny there is a problem.

Both rear tail lights (brake and running lights) are not functioning properly. the passenger side isn't working all together and the drivers side will sometimes be on and other times not. the dealership wants $679 each side for replacements. this seems like quite a big expense for a safety issue that gm needs to address.

2015 brake light works intermittently

Led brake light is faulty. dealership wants over $800 for repair of single light. seems to be a known problem for this make and model.

The rear taillight works intermittently. i have reported it to the dealership and the only fix is to replace the housing unit at $1500. it has been reported and is a known problem with gmc.

Led taillight is already out - should last for 10+ years, car is out of warranty, dealer charges $750 to replace and can't guarantee it won't happen again. dealer can't explain why the light is out, says it just happens

The circuit boards on my brake lights are out. i have found that when moisture gets in them or when i hit a bump in the road they stop working. sometimes they work and sometimes they don't. this happens daily...when they vehicle stationary, in motion, on a city street or on a highway.

Brake lights working intermittently. occasionally either the right or left will not light up. not repeatable or consistent and dealer notes no service bulletins or codes.

Driver side tail light and break light does not work intermittently. under 32k miles. dealer does not cover as there is no recall.

The vehicle has under 40,000 miles and the brake lights have failed. these are led type brake lights so they should last much longer. you can not replace the individual bulbs. you must replace the whole tail light assembly at the cost of $750 each. a warning on the dash never appeared to notify me that the brake light was not functioning.

Both brake lights failed within weeks of each other - around 60k miles. faulty led circuit boards. light assemblies are not repairable by dealership. new assembly over $500 each. gm takes no responsibility in resolving the issue. unacceptable! no more gms for my family! .. and that includes chevy.

Headlight has water condensation in it and dealership says it's a sealed unit so the whole headlight needs replaced and if it happened to the passenger side it's most likely going to happen to the driver side 1 headlight cost $1,200 to replace and labor if gmc knows this is a problem with the 2015 yukons how come something is not being done about it because $1,200 is not a small amount of money!

Driver side tail light quit working

Led circuit board fail. dealership will fix for over $2000 with the old faulty parts instead of the new parts. hundreds of people have had this same issue and it needs to be addressed.

Passenger side brake light out. i see there are over 100 complaints, and no recall. come on gmc, this is a serious safety hazard.

Passenger brake light inconsistanly will work one day then stop working. the next day it will be working again. the brake light is an led strip and cannot be replaced. this has been going on for months and the car has 10k miles. we never know if and when the light will be working. i have been taking pictures documenting the brake light and it appears to work for 2 weeks then goes out for a week and then comes back on for two weeks.

Vehicle front headlight and taillight leds are out. three out of the four lights have gone out in the last month.

Tl* the contact owns a 2015 gmc yukon. while driving various speeds or while the vehicle was stationary, the brake lights failed to illuminate when the brake pedal was depressed. the failure occurred on several occasions. there were no warning indicators illuminated. the vehicle was taken to allen cadillac gmc (28332 camino capistrano, laguna niguel, ca 92677, (949) 485-3700) where it was diagnosed that the led circuit panel was failing and needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure. the failure mileage was 30,800.

Driver side brake lights (entire light assembly) no longer work.

I was driving down the road and someone clearly (due to the loud screeching of the tires) almost rear ended me. thankfully they were able to stop just before hitting my vehicle. he caught me at a stop light and informed me that both of my brake lights were out unbeknownst to me. i have since taken the vehicle to the dealership, but there is an issue with the brake light system/parts for this vehicle. the brake light will work sporadically (without any knowledge of an issue). the manufacturer had to have known there was an issue with this part due to the owner's manual even stating "contact gmc dealership" without giving any troubleshooting advise on the light. the part is ~$650 to replace, both of my brake/tail lights have gone out within a 3 week period of each other and the dealership didn't seem surprised at all of this issue.

Tl* the contact owns a 2015 gmc yukon. while driving 30 mph, the contact depressed the brake pedal and the brake lights failed to illuminate. the contact stated that the failure occurred twice, once with the passenger side brake light and the second failure was with the driver's side brake light. the vehicle was taken to boulevard buick gmc (2800 cherry ave, signal hill, ca 90755, (562) 492-1000) for both failures and the contact was informed that the tail lights needed to be replaced. the vehicle was repaired. the manufacturer was made aware of the failures. the failure mileage was 48,000.

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.

Led brake lights have gone out and there is not a reasonable repair.

Faulty brake lights. goes out intermittently and then stops working altogether. cannot be fixed or repaired whether it is one led light or many- the whole led display is faulty and stops working. dealer was going to charge $750 to fix- for just 1 rear brake light. not having fully functioning brake lights on a 3 year old car is unacceptable and should be under recall- it's a safety issue and obviously a faulty part when there are numerous complaints and blog posts about the same issue.

Taillight failure. gm is aware of the problem, it's all over the internet. now out of warranty and dealer wants $800+ each to fix.

Wiring on the brake lights is faulty causing the light to work on and off. while driving you don't know if your brake lights are working because they come on and off at times

The brake lights on my 2015 are defective. the driver side light went out about nine months ago and now the passenger side light is out. our local dealership wants $800 apiece for these led lights that should last many, many years. a quick internet search reveals that 1) the problem is widespread and 2) gm won't acknowledge it. working brake lights are a matter of safety, and the fact that gm produces these lights as cheaply as possible and then charges an arm and a leg after the parts fail early in their lifetime is suspect to say the least.

Tl* the contact owns a 2015 gmc yukon. while driving various speeds, the driver side tail lamp failed without warning. the vehicle was taken to beaman buick gmc (located at 1531 broadway, nashville, tn) where it was diagnosed that the tail lamp assembly malfunctioned and needed to be replaced. the vehicle was not repaired. the contact stated that the passenger side tail lamp assembly previously failed and was replaced. the manufacturer was not notified of the failure. the failure mileage was approximately 60,000.

Rear brake light assembly for both the left and right side work intermittently. we have already replaced the right side for a cost of $600.00 for the light assembly only.

Brake light stopped working, gmc wants to replace the whole assembly for $800. my warranty has expired but i think gmc should have away to repair the light instead of replacing the whole assembly. a recall on this shady way of getting the consumer hard earned money. because it should last longer. i can't drive my car in fear of getting a ticket. please help

Tail light has been flickering for months and now is out. gmc will not fix because i am 4 months out of warranty. i only have 18,000 miles on my yukon.

I was told my a collegue that my drivers side brake light was out. i took it into the local mechanic and it was not out. a few months go by and i am told again, that my drivers side tail light is out. i take it to a different shop and it is working correctly. the very next day a truck tells me at a stop light that i have no brake lights. i was pulled over by a police officer for not having properly working break lights. he let's me go with a friendly notice, but as soon as i started my vehicle to drive away he immediately pulls me back over to tell me that he was mistaken that only my driers side brake light was out. this has happened intermittently over the last three to four months.

Defective tail light assembly. inadequate material/design defect leads to circuit connection failure. gm is aware of the problem but still charges $800-900 to repair the oem defect. major safety issue having tail light failure. we have many yukons in our fleet and all have had failures.

2015 yukon xl passenger side brake lights don't work

Rear lights and brake lights do not work on both sides.

The passenger side headlight assembly was working and now after having the truck since april the running light has gone out completely. it was already hard seeing the road ahead with the lights working because all of them are so dim but now it is even worse. the entire headlight has to be replaced because of moisture inside the so called sealed assembly. i took the truck to the dealership only to find out that it will cost me $1200 plus dollars for the light and labor this is really ridiculous. i have read on many different gmc forums that this is an all around state to state problem that i think gmc should address not only because of the cost but because of the safety issues that this poses. please do something about this problem.

Both brake lights went out. dealer said had to replace entire fixture. not covered under bumper to bumper extended warranty purchased. safety hazard that many other 2015 yukon owners have experienced. trim/seal appliqus around door windows also coming off and also not co weed under b2b warranty. shottily made vehicle.

Brakes don't work well when traveling at low rates of speed. stopping requires brakes to be pressed to the ground and still may not stop. i have almost had several accidents even after having the issue 'repaired' last year. i've had the problem assessed at 3 different mechanics. i have had to throw my car into park to avoid hitting cars in front of me. brakes fail while driving in places such as traffic jams, drive thru, school pick up, etc. this is a huge safety hazard and fear that my children may be hurt if this issue is not corrected by the manufacturer. steering becomes nearly impossible when the brake issues occur. this is an ongoing problem for the last 1.5- 2 years. also, the tail lights continue to go out even after paying hundreds of dollars for replacements.

Water/condensation in headlamp, no indication of cracks, turn signal and portion of headlight is now malfunctioning. this is a constant problem.

Passengers side brake light was only intermittently until it quit all together then the drivers side did the same thing. i called the local dealer about it last year and they stated they were not under warranty and the cost to replace them was over $800 each.

The brake lights on 2015 and newer gmc yukon, yukon xl, denali, denali xl vehicles fail due to poor quality circuit metal/design of board allowing too narrow a connection for metal used. the result is a crack in the circuits metal which, depending on conditions, breaks the circuit and the tail lights fail to work. specifically brake lights fail first putting the driver of the vehicle in an serious safety situation with no indication that the failure has happened. in addition, the safety of drivers behind a gm vehicle exhibiting this problem are at serious risk as they may not realize the vehicle is coming to a stop. gmc is refusing to cover the issue and requires $800 per light and openly acknowledges that the new light can do the same thing at any given time. i don't normally go so far with an issue, but this seems particularly dangerous and warrants a recall. with the lack of indication other than courteous drivers telling you the lights are out or police pulling you over to tell you, the issues often start within warranty period but no way to know. numerous reports of tail light failures with new vehicles indicate that the issue is not related to age. as with my lights, no physical damage to the light at all eliminates some kind of impact outside of normal road bumps. hopefully action can be taken.

At less than 3 years old both taillights have quit. they are a sealed assembly so the whole side needs replaced. we were quoted $750 each. our three year old yukon has no taillights and will take $1500 to replace. i'm disappointed in gm to say the least.

I have a 2015 gmc yukon with condensation in the right and left front headlight assemblies. my turn indicator stopped working which usually indicates a burned out bulb. i did not notice the condensation and i took my yukon to the dealership for what i thought was going to be a simple bulb replacement. the headlight assemblies are completely sealed which requires the replacement of the complete lamp assembly if a bulb filament burns out. the dealership pointed out the condensation and told me the bulb malfunction is likely caused by the condensation. since my visit to the dealership yesterday, the turn indicator has worked intermittently. a call back to the dealership with the update and the response was that the condensation likely caused corrosion and still needed to be replaced. they advised me the other headlight and signal indicator were likely to malfunction as well. it is obviously an ongoing issue since gm issued a technical service bulletin around may 2014 and updated it in march 2016 to include 2016 and 2017 models. the condensation covers the entire lens. this is obviously an issue at night when using the headlights. the headlight assembly is non serviceable - entire headlight assembly must be replaced for non-working bulb at a huge cost $1200/side). gms technical service bulletin notes that if certain conditions are noted (such as in my case), the replacement of the lamp assembly may not correct this condition.

Tl* the contact owns a 2015 gmc yukon. while driving 60 mph, the exterior door applique covers rattled violently. the contact was informed to contact the manufacturer to report a non-safety related defect. the contact also stated that the rear passenger side brake light failed intermittently. the vehicle was not diagnosed or repaired. the manufacturer was not notified of the failure. the failure mileage was approximately 40,600.

Tl* the contact owns a 2015 gmc yukon. while driving various speeds, the brake lights failed to illuminate when the brake pedal was depressed. the dealer diagnosed that the tail assembly needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure. the failure mileage was 35,510.

Left rear tail light quit working, i was able to break the cover off and soldered the led mounting strip,. right side quit working so i broke the cover off but this time it was severely damaged. soldered it. left side quit working again so i replaced both sides with aftermarket units. date below is just to fill the space. it was after warranty expired and over about 6 months time.

I would like to resort how hard it is to tell if these vehicles are turning or braking due to the "brake-light-turn-signal combination" where the brake light goes off when the turn signal is on.

Passenger brake light does not work. we have had problems with it since day one. we took it back several times but still doesn't work.
