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.
2015 GMC Yukon lights complaints
Page 9 of 10: complaints 221 to 250 of 269, newest first, as owners wrote them.
Tl* the contact owns a 2015 gmc yukon. While driving 65 MPH, the brake pedal was depressed, but the brake lights, tail lights, and the interior rear brake light flickered. The vehicle was taken to delano chevrolet buick gmc (600 1st ave, delano, ca 93215, 661‑735‑4974) to be diagnosed and repaired. The diagnosis results were unavailable. The manufacturer was not notified of the failure. The failure mileage was approximately 92,000.
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.
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.
Brake lights only work intermittently. This poses a safety hazard while driving and could cause a wreck. Replacement is $800 per light, very cost prohibitive.
My vehicle is currently a little over 3 years old and I have owned the vehicle for the last 2.5 years. I am highly upset that the vehicle is in great condition, however the front driver side LED strip in the head light is out. I purchased an extended warranty for almost $2000 when I bought the vehicle which they will not cover. I also have the back passenger tail light out and I am told that the whole panel needs replacing. A total for the LED strip and back panel will cost close to $1900. Why in the world is it that and LED light is supposed to last 5x longer than a regular light, but it just goes out? That makes no sense. If the vehicle was 10 years old, that is one thing, but it being still on the new end, makes no sense. Also, how does the whole back light panel just go out? And why do dealerships act like " oh well, there is nothing we can do!" gmc must be lowering their standards. Had I known this vehicle would have these problems and no one seems to want to help, then I would have never bought it. Something needs to be done, especially since I have spend the last 30 minutes reading a forum of a large amount of others having had the same issue.
Led brake lights have gone out and there is not a reasonable repair.
Rear brake lights failed.
Both driver side and passenger side rear brake lights fail intermittently. At times it's just one side or the other, occasionally both sides fail at the same time. This is a 2015 vehicle with 40k miles and both lighting assembly's are failing.
Driver side brake LED lighting is working intermittently. Had it replaced under warranty. Passenger side brake LED lighting now working intermittently, new issue. Have not had replaced yet due to outrageous cost($700) for fixture replacement. Only 40,000 miles on vehicle obviously reflects a serious safety issue to financially strapped consumers.
Passenger side LED taillight assembly is out with only 22,000 miles its past the 3 year warranty period. The dealership is asking approx $700 to replace/repair.
Bought 2015 yukon in september 17, certified by dealer and june 18 I noticed rear light flickering on driver side. Bought warranty for truck and it's not covered. Dealer says 876$ for one new light . I have read online now where alot of complaints are being made for same issue. Also have exterior black door panel flapping in the wind and dealer says that's not covered under warranty either. Looks like I will be trading this truck in asap
I was pulled over for no brake lights, officer told me he has the same vehicle and that he has the same problem. The brake lights come on and off when ever they want to. Very very unsafe
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.
Led tail lights/brake lights not working due to bad circuit boards in the lamp housing when in motion or in park. Gm says there is a upgrade kit but they made them where you can not get into them and fix them without replacing the whole unit which runs an average of $650 and up each. Brake lights are a serious safety hazard if they do not work. I have been on many blog sites with hundreds of people experiencing the same issues on the same vehicle. Gm should recall them and replace them with the upgrade kit because it is a manufacturing defect and a safety hazard on the road.
Tl* the contact owns a 2015 gmc yukon. While driving at an unknown speed, the brake lights failed to illuminate. There were no warning indicators illuminated. The vehicle was taken to an independent mechanic who diagnosed that the brake light assembly failed and needed replacement. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 54,000. The VIN was not available.
Rear tail light not working
When the car is turned on, the passenger tail light assembly is malfunctioning and inconsistently work, but the turn signal and brake lights are working in the same assembly.
Right brake light no longer works. Unable to replace bulb and have to spend 775 on a new light housing since these are not serviceable lights
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.
Brake light burnt out requiring the entire tail light lens to be replaced at a substantial and excessive cost over $800 for parts and labor. Vehicle mileage under 36,000 miles.
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.
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.
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.
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!
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.
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
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
