Problems with 2016 GMC Yukon XL EXTERIOR LIGHTING

Brake light has gone out twice in 3 years.

My rear tail lights stopped working and the dealership is charging $800 to replace the module. previously i had a 2016 yukon xl and the same thing happened around 40k miles. my sister-in-law also has a 2016 yukon xl and one of her tail lights did the same thing. after searching online this seems to be a common problem with 2015 and 2016 yukon xl models and gm should be replacing these parts at no cost to these thousands of people experiencing this problem when the car isn't even 5 years old.

Led brake lights don't work car shakes and transmission shudders while driving 35-45mph

Right tail light went put, took it to get fixed. they said it was the circuit board and i had to pay $900 to get it fixed. the dealership said they have had a ton of the circuit board replacements and didn't know why gm didn't do a recall. now, my left side circuit board is out and needs to be replaced.

Tail light went out and is a known and common issue within 2 to 4 years of vehicle ownership (often both sides go out). in my case, the driver side tail light went out. total cost for me was $850. there are many comments regarding this online. typical cost to repair is $700 to $800 at dealership. only other option to reduce cost is to mail out part, but this leaves you without a vehicle for several days for repair and delivery time.

Tl* the contact owns a 2016 gmc yukon xl. while the vehicle was parked, the contact's wife noticed a leak entering the cabin from the overhead antenna. there were no warning indicators illuminated. also, while pulling into the driveway and depressing the brake pedal, the contact's neighbor informed him that all the rear brake lights (rear driver and passenger side brake lights and tailgate brake light) were not functioning. the vehicle was taken to north county buick gmc (located at 1515 auto park way n, escondido, ca 92029, (866) 852-7135) where it was diagnosed that the overhead antenna and all three brake lights needed to be replaced. the contact stated that the rear driver's side brake light and antenna were repaired, but the other brake lights were still not repaired. the manufacturer was informed of the failures. the failure mileage was 61,000.

The tailight/brake light keep going bad. it works half the time. i will check it and it's working then i hit a bump and people tell me it's not working. i hit another bump i look and it working. after replacing it once already has the exact same problem and they want another $1000 to fix it but the dealer told me gmc now has a better replacement for it. if they have a better built option then gmc should be made to change lights on all of them before some one gets killed.

I was notified by another driver my passenger rear tail light was out. there is no notification on the dashboard to alert drivers. the next day the light was working. i continued to check it periodically and figured it was a fluke. i was stopped again while driving that the light was out roughly a week later. after looking into repair the cost is ridiculous $650-$800+ and it appears to be a widely known issue. i was actually in a parking lot and saw a vehicle exactly like mine same light out. not sure why lights are going out in a three year old vehicle just hitting 40000 miles.

My wife was driving down a major road and a person pulled next to her at a stop to tell her that her brake lights were working only part of the time. gm had just serviced my vehicle and didn't catch it, and upon researching the issue, it is a known faulty design of the tail light assembly. the led brake light starts intermittently failing at the 2 year point, leading to drivers following drivers to not know that the leading vehicle is stopping. this is a common issue and the only response from gm is to make the customer buy a new $700 brake light assembly. the issue is so common that multiple companies have started brake light repair services and multiple youtube videos exist to walk individuals through the process of repairing their own brake lights. the cost of the repair is so steep that i hesitate to get the problem fixed, and though gm reportedly has developed a replacement light assembly that corrects the fault, they are not taking responsibility for the defective brake light assemble that these vehicles come off the assembly line with. the major danger is that we drive from the front of the vehicle and likely do not know our brake lights are intermittently failing--since gm cannot even catch this when they do service on vehicles (mine had been in the shop for an oil change a few weeks before the brake issue), then they are leaving a lot of customers driving without brake lights to avoid the cost of the repair even though they approved a faulty design.

Both led tail lights started flickering and failed within a month of each other. the mechanic said this was a known issue with these lights and that the circuit board failed.

Driver side rear brake and tail light and turn signal works intermittently. sometimes it works fine, some times it flickers, and sometimes it it totally out. this issue happens randomly. i have seen it while parked, and while going down the road

The passenger side brake light stopped working with no indication on the instrument panel. this appears to be a common problem for model years 2015 thru 2019 due to a design/manufacturing defect. the repair involves replacing the entire taillight assembly for about $800. the dealer will not repair under warranty after 2 years or 24,000 miles even though it is a safety related defect. there is not a safety recall at the present time. my vehicle is over 2 years old but only has 20,000 miles.

Brake lights faulty. have had both passenger and driver's side replaced. drivers side is now shorting out again. tons of owners of the yukon line have had the exact same problem with faulty tail lights. law enforcement thinks it is a major safety issue which it is! these tail lights work intermittently or not at all!

Drivers brake light shorts out and stops working.

Rear driver's side brake light is inoperable. my vehicle is less than 3 years old. if my local police department views this as a problem, so should the nhtsa. gmc needs to recall this known problem. how many people have to report this problem for it to be addressed? this is a safety issue!!!

Rear passenger brake light has stopped working. took into dealership and it appears gmc does not cover under warranty. it appears that there are numerous reports of rear brake light issues with gmc vehicles, specifically yukons but gmc continues to indicate this is not a problem.

The right tail light and brake light failed at only 44,000 miles. fails to work in all phases of operation.

Drivers' side brake light/tail light failure at 44k miles. gmc refuses to fix under warranty (even with extended warranty purchased) despite thousands of people having this issue. dealer quoted $1,000 to fix just the one side and admitted this is a known issue. i was stopped by another driver at a red light to inform me of the issue - he said he nearly hit me because of it and was scared.

Gmc 2016 yukon xl denali back taillights and brake lights are out. all of them. very dangerous. gmc denied responsibility but everyone i know that has the same car says they have had issues. never had this in any other vehicle in 30+ years of driving. they are obviously faulty and they need to accept responsibility

A few months ago the driver side taillight stopped working (or would only work intermittently). took to dealer and they said it was $850 to repair. filed complaint with gmc and as i was working through that with them the passenger side taillight stopped working as well. now i have a vehicle that is not even 3 years old without working taillights. this is totally ridiculous. a $65,000 'professional grade' vehicle should not be having this issue at 55,000 miles. gmc needs to wake up and recall these. will it take a fatal accident to spur a recall??

Driver side brake light out . its a known issue with the lights and gmc refuses to acknowledge its an issue...

My left taillight is out. there was no damage to the light it just stopped working! it would work sometime and sometime it would not. now it is not working at all!

The right rear tail light brake lights have gone completely out. these are one solid housing and have to be replaced to simply fix the brake light. reverse and turn signal lights are ok. the housings cost 600-700 dollars each to replace which is a ludicrous amount to have to spend. in order to be within regulations for inspection, these have to be working. we feel there should be a recall as there are lots of complaints online about these housings.

The drivers side brake/rail light stopped working and vehicle only has 27,800 miles on it. have seen and heard of many others with the same problem. led lights should last longer then incandescent lights.

Tl* the contact owns a 2016 gmc yukon xl. the contact stated that while stopped at a traffic light, the contact was informed that the brake lights were inoperable. the vehicle was taken to texan gmc buick located at 18225 eastex fwy, humble, tx 77338, (281) 973-3117, to be diagnosed. the contact was informed that brake lamp bulbs needed to be replaced. the vehicle was not repaired. the manufacturer had been informed of failure. the failure mileage was 92,000.

Rear right brake light went out due to known defect. metal piece broke that allows a connection between the led lights. gmc should recall these lights since there are so many people having safety issues with them.

The rear brake lights are not functioning consistently. the turn light and reverse light work but not the break lights. they are their own assembly and have to be replaced at a cost of $650/each at the dealership. online i found hundreds of others that had the same issue.

The passenger side taillight on the vehicle works intermittently. as of late is has been completely out and not functioning at all.

Running boards failing to work properly all the time. sometimes will start to go down but return up when opening door. will also fail to go up after closing door and remain down. middle row dvd screen is black and not working. rear brake lights working off and on. horrible loud squealing sound under the hood. the vehicle will also begin to shake randomly and feels jumpy at times.

Vehicle has 52,000 miles on it and driver side tail light stopped working. it is an led and should last for many years. has not been in an accident. this is faulty manufacturing. consumer protection needed.

Rear passenger light is not working. the board is cheaply made and dealer wants me to buy a new light fixture for $800.

My drivers side tail light is out! dealer charges $700 to repair!

The right rear brake light quit working. will come on when pushed against car. dealer said it was electrical in the brake light unit.

Rear brake light works intermittently.

Rear tail light / brake light quit working while still under warranty. we took it to the dealer and was denied covered. the unit is a complete led assembly and cannot be repaired. the price quoted was $700 for the assembly. a quick internet search shows that thousands of people have experienced the same issue and gm will not acknowledge it as a problem and will not cover under warranty. this is most definitely a dangerous situation for owners who suddenly have no tail or brake lights on their new/newer vehicles.

Rear led brake lights no longer light up.

The back massager tail light has stopped working. after much research this seems to be a problem with the vehicle. to replace the light (one light), i was quoted $750.

Faulty break lights. the led circuit is faulty and cracks which requires the entire light assembly to be replaced.

Rear led tail lamps have a high failure rate, leaving the vehicle in the dark at night. this has occurred 2 time over the past 2 years. light has now been out since jan 2019 and gm claims they are still waiting on the part.

Tail light issues. replaced driver side light approximately less then 6 months ago and passenger tail light is out. same issues as driver side light.

I have been told by multiple people that one or both of my brake lights has not been working. i have tested them myself and i too get mixed results. sometimes one works and other times neither. being that i drive 30 minutes to and from work everyday this is a major concern.

My car is barely 3 years old and has only 24,000 miles on it because i work from home. i specifically lease cars so i don't have to deal with issues. this cars rear passenger brake light no longer works! the service manager at the gmc dealership says they have to replace a great deal of these in cars not very old like mine. this is definitely a safety issue for brake lights to be going out on a 3 year old car! it has been out for months and i was just procrastinating because you must go to a dealership shop to get it replaced. you cannot get it at a part store yourself so my car probably only had 20,000-21,000 miles on it when this started.

Rear passenger brake light stop working, vehicle is only 2 years old. we should not be having this issue so soon or at all, since led lights normally dont stop working. i also looked into fixing it and its gonna cost $700 dollars. this is ridiculous!

Tl* the contact owns a 2016 gmc yukon xl. the contact stated that the passenger side tail light was inoperable. the contact took the vehicle to prince chevrolet of albany (2701 ledo road, albany, georgia 31707, 229-432-6271) twice for the tail light failure; however, the dealer stated that the replacement led light was not available to correct the failure. the manufacturer was not contacted. the vehicle was not repaired. the approximate failure mileage was 60,000.

Progressive intermittent brake light functionality that eventually culminated with complete inoperability; only the right/left brake light assemblies are affected; reverse lamps operate; upper center brake light functions normally; this is a known problem with gmc brake light assemblies per multiple forums

Driverside tail light intermittently stops working. car milage is in the 40,000's. diagnostic test at dealership where purchased confirms " driver rear tail light shorted out internally. recommend replacing driver tail light. recommend tail light assembly $899" . my sister has a yukon xl denali 2016 and has the similar issue but both of her tail lights intermittently stop working posing a huge safety concern. driving in my area i see many newer yukon xl with the driver side tail light out. lighting is not covered under extended warranty and cost to fix is extremely expensive, which could make the average driver put off the large expense. the tail light intermittantly stops working while the car is on, does not make a difference if the car is stationary or in motion. service rep at dealership stated this problem is "common".

Both tail lights and brake lights stopped functioning within a week of each other. no bulb to replace as they are leds and entire housing has to be replaced.

Model yukon xl 2016, less than 50k miles, brake lights have failed completely. no rear braking lights. entire assembly has to be replaced. first noticed in july, have only had vehicle for 14 months.

Gmc brake light failure - i own a 2016 gmc yukon xl and after about 45,000 miles the brake lights have started intermittently not working. after having a gmc technician tell me that its a known issue and seeing hundreds of others posts online, it is evident that this is a very widespread problem. i was nearly involved in a rear end crash on the freeway because the driver told me i did not have any brake lights. this is a serious safety issue and gmc needs to correct it. they want me to purchase 2 replacement light units at 750.00 each.

Both break lights went out, weather has been hot in the high 90s which gmc dealer expressed common concern among owners during summer. vehicle is used 15miles/day on average.
