On our 2016 GMC Yukon Denali we have experienced intermittently working brake lights on our vehicle. We were first informed by a family friend following us that our passenger side was going in and out and now our driver's side brake light is completely out. The turn signal and reverse light still works but no brake light of any indication. No warnings or messages were given it just went completely out. I believe this is a safety hazard to myself and other driver's. It is also against the law to have a break light out. I've read that there was a recall but it was dismissed in 2021 due to faulty break lights. I also read that it was only fixed at no cost for drivers at 72,000 miles and the vehicle couldn't be older than six years.We purchased our vehicle at 73××× . Not everyone can afford the $1600.00 upfront to fix a problem like this. Please reconsider making this a recall as I have been doing my research alot of Gmc Yukon drivers have experienced this. I want my family to be safe.
2016 GMC Yukon electrical complaints
Page 2 of 3: complaints 11 to 40 of 53, newest first, as owners wrote them.
In my experience of transmission failure with my 16’ GMC YUKON, there was no warning. I had not experienced any issues with the slipping or jerking feel when accelerating or braking as described in the class action law suit. My vehicle had 105k miles, I took it in for regular maintenance including having the transmission flushed as I was told to do so for preventative maintenance. The transmission failed when I was traveling on the interstate with my family and I came upon some traffic so I applied the brake and the whole vehicle bucked and jerked as it shifted into down gear. I was traveling at 30-35 mph in the traffic and the whole time I felt a slipping motion in the car. I made it to a gas station, refueled, and tried to restart my journey. As I leery the gas station accelerating to get back on the interstate, the vehicle would not accelerate above 35 mph and the RPMs we’re to the max. At this point, my vehicle was in drivable. No prior warning, no issues that had been occurring over time, this all happened the same day. I towed my vehicle to a Chevrolet dealer where the problem was identified as a failed transmission in need of replacement and failed ABS braking system. The cost came at $6800.
Tail lights/brake lights /signal lights go on and go off danger of being hit from the rear dealer and independent service has confirmed defect and say it is common vehicle has not been inspected be the police or insurance there was no warning lamps or messages first discover 2 years ago when drivers would pull up and say the lights were out......we would stop and look they would come back on
I was driving with a trailer that has brakes. A warning system light came on “trailer brake system” service came on blind the digital speedometer. Brakes would not engage. A couple of day later same thin came on now with out a trailer. The warning would not go away and kept on chumming every 10 seconds.
The largest issue was today, 2/22/2022, when I was driving doing 56 miles per hour it felt like it wouldn't accelerate. Then all of a sudden, the wheel kind of jerked right and the car shifted down all on it's own and I was doing 25 mph. The check engine light came on immediately after the violent jerking happened. I was on a 4 lane highway and had to immediately pull over onto the shoulder. It was jerking forward and back as I was trying to pull over on a freeway where the speed limit is 70 mph!!! I had my 80-year-old mother in the car with me. AND YES!! It put us both at great risk! I had to call a tow truck and they towed it to a dealership 9.8 miles away. When I talked to the Assistant Manager, he said that there were 3 other GMC Yukon 2016 that had come in today - ALL WERE 2016 GMC YUKON MODELS WITH 125K MILES. My GMC has 124,700 MILES all with Transmission problems. This can't be an anomaly. So I got online and there are many, many complaints about this transmission. As a matter of fact, it appears in 2019 there was a Class Action Lawsuit about this very thing. I will not know until tomorrow for sure what the issue is - because the dealership could not get to it today. However, something significant happened. As a side note, recently I had an electrical problem where sensors, etc are all saying need to be serviced and none of them are working. I had appt today at 10:30 am to have them check this. On the way there, the violent jerking and sudden downshift and check engine light came on. I was scared to death and so I pulled over and called a tow truck. The dealership did not tell me this is a common issue, nor was I aware. The dealership told me if it is in fact the transmission - cost is $6,000!!! I need someone to contact me to discuss this.

Rear driver taillight assembly does not work all the time! One day it works the next day it does not! I had to have the passenger side replaced about 6-8 months ago & it was replaced by the dealer at that time & there was no cost to me as it was under warranty at that time! I think there may be an issue with the LED bulbs! Now the problem is with the drivers side! This is a safety problem and a recall should be issued!!!!It is no longer under warranty & out of pocket cost may be $600 to $1000!
The rear lights on my vehicle - including brake lights - intermittently stop working. I was unaware of this issue until I had someone follow me to my destination to make me aware. This is extremely dangerous that could lead to a wreck with the potential of bodily injury. GMC has issued a service bulletin (admitting to using faulty parts) related to this problem, however, they have limited the coverage to mileage and year. GMC should be required to issue a full recall on any vehicle impacted by this serious safety concern.
I purchased my car brand new. After one week I notice my car jerking when shifting gears. I took the car back to the same dealership I brought it from, the service manager told me thats how it changes gears from 4 cylinder to 8 cylinder. So me believing in the service manager, I went along with him. Well after having different people ride with me they asked me what is wrong with your nee car? Why is it shifting gears so hard. So I took it back in to dealership I talk to same service manager that my car is jerking and making a loud noise . Well lets just say I got the run around. Then 6 months later I took it back and forth multiple times for same problem. Now this time my turning signals we blinking on and off, whenever I washed my car or it rained. Then my front headlights were doing the same thing, then the back tail lights were going on and off. Now onto my heated and A/C seats were not working. Then my interior lights wete staying on, monitor display was shorting out. Now it 2020 and my hood and top of the car are oxidizing. I thought I paid $80k for this car and this what happens!! I park in the garage too! There is alot more problems to add, but not enough space to put down. Im dealing with the gmc headquarters now. My car is a lemon!!
The Trailer Brake System has become inoperative on my 2016 GMC Yukon. . A random, constant and repetitive Service "Trailer Brake System" warning makes constant, persistent, repetitive and abrupt dashboard visual illuminations and abrupt audio disruptions while driving. This causes constant driver distractions and the inability to hear traffic and other warnings when the chiming audio warnings go off over and over. Additionally, the Trailer brake system is not functioning and other potential issues may exist. I have learned that the federal safety agency and GM are aware of this specific Trailer Brake System issue but have not provided a remedy for this known Manufacturers defect with the wiring harness. These disruptions prevent our family while driving from hearing other vehicle warnings (turn signal, rear collision, lane departure, lane assist, forward collision) and I am unable to make phone calls as well during these constant disruptions and also the inability to read the digital read out of my speed during these constant disruptions.
Rear Left tail light doesn't turn on. Was stopped by police and given a verbal warning of my tail light turning off and on while driving. Now its completely dead.
This is the second time it happened the first time i parked my car while the engine was on and i got down real quick got back on my car and when i tryed turning all of a sudden my steering wheel keept turning the opposite way and parking control light appear saying it was off and it keep moving my steering wheel i all of a sudden turned my car off and back on the second time that happened i was going in a parking when it did the samething i was turning in the parking and it started turning my steering wheel the opposite way it started saying again parking control off and the system started going crazy and my car completely turned off i was left in the middle of the parking lot had tu put my car in parking and turn my car off reall quick and turned it on and was able to park but i did get really scared and been really scared to drive my car ever since because i don’t know if it will do the same thing again while driving . I have not taken it to get checked but will be making an appointment because it is a really scary situation.
I see almost 200 complaints and nothing has been done? Not sure the point of this website, but, I'm going to put my 2 cents in. My 2016 yukon denali passanger brake light has gone out, like many, many of other people. Why isn't this a recall? Obviously, there is a manufacturing issue that needs to be addressed. After many videos I have watched I see that the circit board comes apart and can't be repaired but only replaced, at a extremly high price. I've also seen many tail light on these yukons work off and on, so, randomly they can not work at any time and possibly get you rear ended. How do I file a civil action complaint to have gmc address this complaint and resolve this issue? Please advise.
Shortly after purchasing the vehicle in sept 2020 my onstar module failed. Started noticing water in the driver floorboard. The shark fin antenna is leaking, causing major electrical failures and shortages. No GPS, onstar won't work. These fins need to be recalled and fixed properly.
Tl* the contact owns a 2016 gmc yukon. The contact stated the seat heater on the driver's side front seat was not heating up properly. The vehicle was taken to rhoden gmc however, the mechanic was unable to duplicate the failure. The vehicle was taken to h&h chevrolet (4645 s 84th st suite a, omaha, ne 68127; (402) 339-2222) for an issue with the infotainment system. The contact was informed there was a electrical short in the wiring and that the antenna needed to be replaced. The vehicle was repaired. The contact stated that since the repair, the instrument panel failed to illuminate normally for short periods of time. Additionally, the blind spot indicator activated independently. The contact also stated that there were issues with the keyfob while attempting to lock the vehicle. The radio screen was also overheated. The contact also stated that while using the heated steering wheel, the cruise control failed to function as designed. The vehicle was taken back to the same dealer and was being repaired. The manufacturer had not been informed of failure. The failure mileage was unknown. The VIN was not available.
Vehicle shuts off and on when making a sharp turn. When reversing into a parking spot the trucks steering wheel got stiff and everything shut off off then on then off and on again. When reversing it did it twice more. Turning to get out of a car wash curve it shut off and on. Turning into my driveway it shut off and on (on two different occasions)
Faulty tail lights. Tail light does not consistently stay lit. This faulty light is going to cause an accident
The passenger side blind spot monitoring sensor not working because the sensor came detached from rear bumper for no apparent reason and now is just dangling. Needs to be welded back on the bumper.
Driver side tail light went out, when you pull the light out it starts to work, replace the light back into the car and it dies again. This seem to be a issues with a lot of people. Its very costly to have to keep replacing LED tail lights!
2016 yukon denali, both brake lights malfunction with on 78k miles. I can't afford new brake lights as they are manufacturer only and $800 a pop. I purchased the extended warranty to cover any of these expenses at another 3k, and the dealer tells me headlights, tail-lights are not covered. I should have researched better, or would not have bought a vehicle with any LED lights.
After refueling my yukon, pulling out into traffic, the yukon's RPM gage started jumping up and upon accelerating, the yukon would not move. I was able to put the yukon in 'm' gear and slowly drive another mile before I was unable to drive the yukon at all. Vehicle had to be towed.
Rear passenger side red LED light doesn't work. Have to replace the whole light assembly which is a lot of money.
Both rear tail lights are out. The replacement for these are over 800.00 and gm has know about this for years. Please help, as I cannot get my car inspected with the lights being out.
Passenger side brake light does not work. This is a known issue with gm. There is poor manufacturing which has caused this chronic failure. Can not replace the bulb, you must replace the entire light assembly.
Brake light taillights intermittent turns on and off
Brake lights stopped working almost was plowed into by 18 wheeler on I-75. Driver waved us over and informed us that he did not see us till right on top of us. Problem appears to be systemic enough that the gmc service department told us that it was common enough that they kept the brake lights in stock. Additionally there are numerous threads about this issue on the internet and even utube videos on where to remove material to access the offending circuit board to repair the known faulty circuit. The failure of these brake lights could have cost my family and me our lives. The dealership wanted to charge 1600$ to replace the brake lights. I reiterate the brake light failure is common enough that there are numerous threads on the internet to discuss the known weakness of the circuit board
My complaint relates to a known defect in 2015-18 gmc yukon (and similar gm models) and defective brake lights. The left brake light in my 2016 gmc yukon went out in approx early 2019. It was repaired under warranty. In november 2019, by right brake light went out. It was the same problem as the early broken light. I had less than 36,000 miles on the vehicle. I leased the vehicle in approx sept 2016 and the dealer claimed that the vehicle was past (less than 75 days) expiration of the 36 month warranty. So, the dealer quoted me $950+/- dollars to replace the entire housing. The dealer rep explained that the entire housing had to be replaced because it was LED and didn't use a bulb. The dealer rep told me this is a common problem. I was incensed and refused to pay. I went home and googled the problem and found out that this is pervasive with the 2015-18 yukon and other similar gm products. I also found a fix that was much less money only required about 2 hours of my time. This is a safety defect and, based on the dealer rep comment and google research, it is a well known problem. For example: https://www.cargurus.com/cars/discussion-t53845_ds768963 http://www.carproblemzoo.com/gmc/yukon/brake-light-problems.php the federal safety agency id number: 11291414 the federal safety agency id number: 11299968 the federal safety agency id number: 11297087 the federal safety agency id number: 11291113 the federal safety agency id number: 11286914 the federal safety agency id number: 11282957 the federal safety agency id number: 11282130 the federal safety agency id number: 11282097 the federal safety agency id number: 11278307 the federal safety agency id number: 11265307 the federal safety agency id number: 11265384 the federal safety agency id number: 11256174 the federal safety agency id number: 11254155 the federal safety agency id number: 11253481 the federal safety agency id number: 11246544 the federal safety agency id number: 11246035 the federal safety agency id number: 11241057 there are many others as well. A broken brake light is a safety defect. Gm should be forced to recall all of the 2015 - 2019 and replace the brake lenses.
Brake light on vehicle works intermittently and is no longer safe. This is a problem gmc is well aware of and no solution in sight. Cheap metal board brakes inside the lens and leaves you with no brake light. I do not want my family to be rear ended because of this professional grade? Brake light failure, at any time on road.this is a 2016 gmc yukon with 22710 miles as I write. Brake light has failed while moving on the city streets. This failure is currently on the passenger side brake light. Trying to make appointment for repair of this professional grade brake light? Before the other one brakes and put my family at risk of a accident.
Tl* the contact owns a 2016 gmc yukon. The contact noticed water coming from the high frequency antenna, which caused a shortage to the GPS and rendered it inoperable. The vehicle was taken to serra chevrolet buick gmc of nashville (2340 galatians pike n, madison, tn 37115, (615) 543-5456) where it was diagnosed that the high frequency antenna needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and provided case number: 9-5724166813. The failure mileage was approximately 60,000. The VIN was not available.
Left taillight went out and I was under the warranty and the dealer replaced it but had the right taillight go out at 40,000 miles. I have referred 4 friends that purchased the same vehicle as us and have had the same issues. This is a common problem with gmc and they need to recall this.
Tl* the contact owns a 2016 gmc yukon. The contact stated that the passenger side brake light failed to illuminate when the brake pedal was depressed.
