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
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.
Passenger side rear tail light LED's stop working, had to replace the whole unit. Not warrantied
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 .
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
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 $1000 to repair. We've recently reasearched the issue online and it seems to be extremely common on this specific vehicle and most people and reputable electricians have stated that it's a result of a faulty part in the unit.
We were stopped at a red light today by someone telling us our tail light was blinking and going out. Our vehicle only has 65000 miles! I would think a LED light should not go out yet. My vehicle sits under a carport when not in use. I have seen numerous complaints online for this same problem for same year model
Left rear tail light quit working, I was able to break the cover off and soldered the LED mounting strip,. Right side quit working so I broke the cover off but this time it was severely damaged. Soldered it. Left side quit working again so I replaced both sides with aftermarket units. Date below is just to fill the space. It was after warranty expired and over about 6 months time.
Intermittent failed passenger tail light on a 2015 yukon, works occasionally. Quoted 650$ to repair poorly manufactured LED lights!
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.
Rear lights and brake lights do not work on both sides.
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.
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
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 side tail lights intermittently stop working
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.
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.
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.
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.
