The rear LED taillights are malfunctioning. The passenger brake light worked intermittently for almost 6 months while before failing completely, while the taillight remained working. Another 6 months have passed and neither the brake or taillight operates. Currently, the driver side brake light works intermittently. Research on this problem shows that they can be corrected, yet gmc dealership has quoted $700 for each light assembly.
2015 GMC Yukon XL lights complaints
Page 4 of 6: complaints 71 to 100 of 140, newest first, as owners wrote them.
Rear LED brake light on right does not work at 60000 miles. The left rear LED brake light was replaced under warrantee in 2016. My mechanic says he has seen this on numerous gmc yukons of this model. Internet search shows many people have same issue. Replacement unit cost is $700. Called gmc who said this was first time they heard of problem with LED rear light unit.
Rear tail light leds flicker on and off and eventually stop working causing the entire housing kit to need replacing.
2015 yukon denali xl intermittently failing tail lights/brake lights due to circuit board getting too hot and not communicating properly between left and right tail lights...part failure/poor manufacturing/safety issue
The rear drivers side brake light is working only intermittently
Tail light on 2015 gmc yukon xl broke on 7/18/19. Authorized gm dealership quoted $902.57 parts and labor to replace. I complained the price is too high and there is a design flaw with the tail light if it costs that much to replace. Led lights are supposed to last longer. There should be a recall for the tail light. Filed a formal written complaint with gmc customer service on 7/22/19. Purchased 2 new tail lights online from carid.com for $495.00 and installed the new tail lights myself. Gmc finally replied on 7/31/19 my claim is denied because I installed the replacement tail lights myself and did not have the dealership install. Gmc advised if the dealership installed then they would have refunded me $495.00. What difference does it make who installed the new replacement light? Driving around with a broken tail light is a safety issue and also against the law and I had to make a quick decision while it took gmc 9 days to reply and it was by phone - still do not have written confirmation. Gmc customer service have a strange procedure whereby you have to have an appointment to speak to a customer service rep. What if you have scheduled a business trip or have to attend a meeting? I have sent a written appeal to gmc protesting their denial decision and at the time of writing have not received a reply. Bottom line is that due to safety issue and it's cause for a traffic citation there should be a recall.
Back driver's side brake LED light out. Dealer wants $900 to fix. Common problem with gm faulty LED lights.
Brake light does not work on passenger side. Cannot be replaced/repaired because the part is on back order.
The brake/tail lights work somedays, and not other days. One day the are both working, one day only one works, and some days neither work. This is a problem that is very prevalent. Just look online. I have personally photographed several of the same issue on this make and model in my hometown. The dealership wants me to pay $1300 to have new lights installed and gmc is in denial of their problem.(the back up/reverse white light works all of the time, its the red brake/tail light that doesn't work) this shows that its an issue that should be recalled, not replaced at the owner's expense.
Left and right brake lights only work intermittently.
Entire driver's side LED brake lights no longer function. Some type of issue with the circuits
2015 gmc yukon xl driver side LED brake light stopped working. Led circuit board is broke. This is a sealed brake light, so there is no fix and has to be replaced.
Tl* the contact owns a 2015 gmc yukon xl. The contact stated that the tail lights on the vehicle became inoperable; however, there was no indication on the instrument panel that the tail lights were inoperable. The vehicle was not diagnosed or repaired. Richard kay superstore (located at 1935 pearman dairy rd, anderson, sc 29625, (864) 332-4031) was informed of the failure and stated that the tail lights needed to be replaced. The vehicle was not repaired. The manufacturer was contacted. The approximate failure mileage was 50,000.
Tail lights work intermittently seems to be a common problem with new yukons. Cuts in and out none working leds brake lights.
Tl* the contact owns a 2015 gmc yukon xl. The contact stated that both tail lights shorted out. The vehicle was taken to courtesy buick gmc (1857 edwards lake rd, birmingham, al 35235, (205) 718-7565) twice for both of the repairs. The dealer and manufacturer indicated that there was no recall campaign to provide a solution and suggesting having the same oem part replaced. The approximate failure mileage was 95,000. *bf
My yukon 2015 had 62,000 miles in may 2019 when the left tail light went out. Because it is an LED light, the part from the dealership average around $700. It was no longer under warranty and I had it replaced in the beginning of june 2019. Today my right rear tail light is now out. Apparently this is a known problem with the 2015 yukons and gmc will not issue a recall or do anything about it. The part is way overpriced. If this is an issue, it should either be recalled for safety reasons or the part should be made available at a more reasonable price. Spending $1500.00 for breaklights in one month is wrong. Please someone reach out and help stop this.
Led brake and running lights intermittently work on one side, issue has gotton worse as temperatures have increased. Appears to work better more often at night. Occurs both when car is running and off. Others appear to have had a similar issue as a result of a cracked circuit in the light housing. It has been occurring for about a month.
Tl* the contact owns a 2015 gmc yukon xl. While driving 60 MPH, the rear driver's side brake light failed to illuminate. The vehicle was taken to five star chevrolet buick gmc (located at 495 watson blvd, warner robins, ga 31093, (478) 387-4424) where it was diagnosed that the brake assembly needed to be replaced. The vehicle was repaired, but the failure recurred approximately 5 months later. The contact took the vehicle back to the dealer for repairs and an oil change. The contact was informed that lifters on the engine and condenser line needed to be replaced. The vehicle was not repaired. The manufacturer was notified. The failure mileage was 96,000.
Left and right LED taillights and brake lights work intermittently. This problem has continued for over a year and is a known problem to gm.
My right brake light was going in and out and then it totally went out. There should be a recall on this issue as plenty of people seem to have the same problem. Led lights should last a lot longer.
My vehicle is a 2015 yukon xl. In 2018 I had to replace my front driver side LED lights and my passenger side rear brake light for a cost over $2,000. I literally had to cancel a family vacation in order to pay for the lights on my vehicle. It is illegal to drive without working brake lights. This year, june 2019, I needed to replace the driver side break light at a cost close to $1,000.
The headlights housings have condensation in them and it has cause the turn signal and LED lights to short out. The LED lights in the tail light housing including the brake lights have also shorted out. The LED screen and computer in the center console has also shorted out.
Driver side tail light would intermittently go in and out from working and not working. The tail light would do this while in motion, while stationary, it did not matter. The local dealership that we bought it from said we would need to replace it. Over $750. Now the passenger side tail light is doing the exact same thing. Huge safety hazard. Clearly a faulty part, not just a bulb going out, but the entire electrical design of the the tail light is flawed. Gm charges you to replace the entire housing with the same exact faulty part that was on there before.
Led taillights are defective. They work intermittently on both sides. See numerous other yukon and yukon xl's around town with the exact same issue. Intermittent brake and tail lights is unsafe. From research I've done, it appears to be a defective part. Gmc should take action.
My passenger tail light has stopped working. I have 50000 miles on my yukon and can not imagine that this should have happened already. The cost to fix the tail light is ridiculous $1300 for one light. I could by a used car for that price. How many complaints does it take for a recall??
There are numerous customers that are experiencing problems with the taillights on the yukon denali xl. Gmc is negligent due to the fact that this problem is a safety hazard and no recall has been initiated.
The driver's side brake light has stopped working. Upon further investigation it was determined that the LED circuit board was broken. A web search indicates that this is a common problem with this vehicle as the circuit board is cheaply made. The brake light cannot be simply replaced. The entire rear light component (brake light, running lights, turn signal) needs to be replaced to repair this. The cost to replace is ~$500. This part should be recalled and replaced with a LED light board that is stronger and lasts longer than 4 years.
Intermittent brake light activation on both left and right. It happens stopped and in motion. Very dangerous! It is a known issue with broken contacts inside a sealed housing. The issue is posted all over the forums but gmc refuses responsibiliy.
Turn signal failure on the passenger side. Cause by condensation in the headlamp assembly. Cost $1300 to replace and get a new turn signal. A turn signal is $5, but then integrated leds cost $1300 because they have to replace the whole assembly.
The passenger side brake light does not work. I replaced the light assembly and it still does not work. The dealership mechanic said it coyld be tge wiring.
