Tail Light Switch problems of the 2015 GMC Yukon - part 1

Rear break light . Internal wiring of the tail lights cracks leading to tail light failure. The failure does not trigger any warnings and the driver is unaware of this failure unless they preform a pre trip inspection.

Rear led tail lights failing. 1 has been replaced already, second, opposite side is now failing.

Both rear tail lights are inoperable and the dealer wants over $800 to replace. I'm over the mileage limit for the recall so I'm out of luck.

Both rear tail light assemblies went bad. The left one in April of 2019 and the right one in January of 2021. Service advisors in the 2 dealerships I deal with claim the do not know anything about it. Yet a number of repair shops on the internet know of this problem in 2015 to 2019 Yukon's because they repair them. Funny that gm does not. I sent the 1st one out and it was repaired for well under the cost of a new one. I complained again to the service advisor about this one to no avail. Going to send it out for repair as well. Incidentally they cover the repair with a lifetime warranty.

Purchased a 2015 Yukon denali back in November 2019. Since purchasing the vehicle we have had to replace the battery, transmission, ac compressor and expansion valve (which still isn't working correctly, because it doesn't blow cold air), and the black panels that are in between the windows. Also, both tail lights have decided to quit working. . . . Which concerns me greatly because cars behind me don't know when I am stopped or applying the breaks. Stopped or have my foot on the break.

Driver tail light works inconsistently.

Tail lights go out. I have read multiple posts about this issue, but yet there is no safety recall issued for this. It is very expensive to replace the lights and I am afraid if I do, the same issue will exist.

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 tail light keeps going out. It was already replaced once at my dealership. Now the same light less than 3 years is not functioning. Posing a safety concern as other vehicles would not see me at a complet stop due to my rear passenger light not working. This should be a safety recall. Its a very common this is a manufacturing defect and GMC should have this fixed ASAP. Tried calling GMC and they said they would not help me with the repair cost of my rear passenger tail light. I stated this was a safety issue and required their attention. To no avail I was denied any assistance. The light itself at my dealership is $800 not including labor. This is my every day family driver car. I have been stopped by cops and given warnings and by other passer by's that my brake light is not functioning safely and appropriately. This needs to be escalted to a safety recall. As there are many threads with other GMC Yukon owners having the same issues. Thank you.

Right rear tail light and brake light stoped working. It is an led light and very expensive. This is a safety concern as lack of a brake light on one side is in violation of legal requirements. Led lights should not quit functioning after 5 years and 85,000 miles.

Rear tail light circuit boards breaking and causing brake lights or tail lights ti fail or not work.

Rear tail lights not working. Both tail lights require replacement. There is an open recall for 2016 GMC Yukon's why is there not an open recall for 2015? this is obviously an issue based on the number of complaints made / reported here.

Rear tail light stopped working going on and off and according to the auto electrician my vehicle could have gotten on fire due to the faulty lights. Upon searching for answers to why my vehicle's back lights were not working, I came upon many other consumers experiencing the same issue. Not only is the cost to replace the lamps so high, we risk in driving a vehicle that could catch fire for such cheaply made lights. And I state this because the auto electrician said that the wire would heat up while driving the vehicle and cause further damages to my Yukon. While driving, you can hear a clear chirping noise that is produced when you brake. This also happens while the vehicle is stationary.

In March 2019 passenger side tail light started working intermittently- took it to the dealer and had it replaced ($800) one year later (may 2020) driver side tail light stopped working completely.

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. .

The left tail light was not turning on when starting the car. Left tail light does not come on when pressing brake. At first, it was intermittent and now it does not come on at all.

Passenger side tail light/brake light goes out intermittently at random. I purchased car used in February 2020 and was informed soon after by friend that my tail light was out when leaving their home. It was working the next day when I checked. I now watch it and see that it works only sometimes. Cost to replace is approximately $700 assuming only a replacement light is needed and nothing else is wrong. Based on the multiple complaints I have seen this sounds like a wiring issue that should be a manufacturer recall for safety reasons.

First, passenger side tail light was going on and off. Sometimes the whole panel would not turn on. Then, a few weeks later the other tail light started doing the same thing and now both brake lights do not come on. They will sporadically start working again ever so often.

The rear tail light led has malfunctioned and will not work or works intermittently.

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.

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.

Right tail light does not illuminate. GMC will not cover this repair even though it is a known issue since my vehicle has over 72,000 miles. This should be covered indefinitely.

Having issues with the tail lights ever since I got the vehicle. First it was one light completely out. Then it worked for awhile, and now both lights are intermittently working. The side yellow lights work on both but the running lights and the brake lights all dont work almost all of the time. Upon reading up on the internet, many many sites as well as local people with the same vehicle, all state they have the exact same issue with their tail lights. It seems to be a very common issue with the same pieces faulting in all of these Yukons. Doesn't matter if vehicle is stopped or moving they hardly ever work.

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. ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.

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!!!.

Left (driver side) rear tail light assembly is completely dead. This is the second time in two years. Will be the third assembly on the vehicle in the five years I have owned it. The assembly does not last. All the led's stop working. There doesn't appear to be any particular reason that the shop can find that it causing it.

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.

Rear taillight does not work. Searched online and found that this is a very common issue, gm refuses to fix and tries to charge $800 to replace whole tail light assembly.

Driver side tail light stopped working. Brake light.

At 32,000 miles we had our back tail light go out. GMC replaced it at cost to them which was around $280 . Less than 6 months later the other tail light went out and dealer told us �lights go out�. We paid full price $680 to have it replaced. Now our left tail light is out again and it'll be another $680 or more to be replaced. This is ridiculous. They are led tail lights. These she last a very long time. Thousands of others are having this problem. Car gurus has a blog solely about this. The odd thing is they are mostly 2015 Yukon�s. A recall needs to be done on this problem and the thousands of people dealing with this should be reimbursed for replacing these tail lights over and over! if you pay 60,000 for a car you should not go through this.

Owned the car for 2 years, been in the shop three times for the same issue, car jerks going less than 25 mph and while driving and accelerating. Both tail lights are led and inoperable. Ac quit working, recharged once and figure it's a leak. Upon reading reviews GMC is aware of faulty parts but no recall on any vehicle.

The rear tail lights do not work. The dealership identified this fault and said that the problem is very common.

Tail lights work inconsistently, dealership tells me it's common problem with my year and model.

The passenger tail light was only working intermittently so I had the whole thing replaced for $750. Now my driver side one is only working intermittently. Also my passenger headlight started accumulating moisture and now the whole led strip doesn't work. There has to be an issue with the company making them!.
