general problems of the 2016 GMC Yukon - part 1

Engine light keeps appearing and when checked it shows catalytic converter needs replaces and its sensors need replaced. Brake light has short in it and I repaireable.

A side detection module pin was corroded and was disrupting the electrical signals to major vehicle components, such as the dash (dic). The dic would lose communication with the rest of the vehicle while driving so no vehicle operation data was visible such as speed, alerts messages, etc. This likely also caused engine failure due to the incorrect operation of the afm which is on the same electrical circuit. No warning messages were given. The bad side detection module was diagnosed and fixed at a dealer and shortly after engine issues were noticed.

I was driving my car Monday and I almost crash with the car in front of me the brakes doesnt work and then in the panel start lights of the engine the supension light and sigh saying brake asistant, the car is park because the brakes and I look for recalls and I call GMC and they says that I dont have any recall but I almost die Monday because the vacum pump for the brakes fail and all the lights in the pannel start light up.

The car has all of a sudden had issues with the gas and breaking. When I press the gas, it stalls then rapidly accelerates. It has to be the transmission. Also, is making a noise and will barely drive when pressing on the gas. It does not accelerate!! could have easily gotten into a car accident! what is going on??.

Loses power randomly. More prominent at low speeds and turns. Has lost power going down the road, will turn back on. Stabilitrak lights and jerking steering wheel are more common. Will not always start right back up when it shuts all the way off/loses power. Loses clock but keeps radio stations. Had it scanned. Asked dealer about issues/recalls and information with nothing more than “this is not common” and “we need to schedule a time for you to bring it in”. Times were not soon and they made it seem like it is not an urgent/emergent situation. Would not agree to me being able to talk with a tech. Looked into this as it seems common but nothing definite. Bad battery cables seem prominent, grounding issues, electronic steering module, and a few others. Seems like a gm problem that is known but not being handled. Greatly disappointed after reading up on it. Many vehicles with similar problems had recalls. Not sure how that process works. I was told it depends where it was manufactured/assembled. Wife was able to get a video of it the other day.

I have a service suspension light that continues to pop up on dashboard the most important issue that needs to be addressed is the brake lights. I have previously had the passenger side brake light stop working. In order to repair this you have to order a whole new taillight. My vehicle was approximatly 6 years old when this started happening. First incident (2022 with approximately 65000 miles) yesterday, I was pulled over by a policeman and both of my brake lights are not working. We found a way to sauder (I know this is incorrect spelling) the broken metal piece back together in the taillight; however, this is not the correct way to fix the underlying problem and clearly it is only a temporary fix because the passenger side broke again in a new spot.

I purchased a used 2016 Yukon xl may 20 2024. Over the last month only put 2k miles on it. I continue to receive a message to service trailer brake system. I dismiss this and it continues to chime and be a nuisance popping up blocking my dash from seeing important things like speed etc and the noise is extremely distracting as a driver. I’m unable to use the hands free talking through bluetooth as it interrupts quite frequently. This makes driving an extremely dangerous and unpleasant ride.

Led tail light out.

Driving a company vehicle [xxx], heavy smoke started coming from under the drivers side dash. Unhooked battery, the smoke stopped. I had vehicle towed to a local garage. They advised the engine wiring harness and other wiring had caught on fire. They couldn't repair it. On [xxx]. I had the vehicle towed to the local GMC dealer in bedford, va. At first they said they could fix it, then around 7/3/24 they said the couldn't fix it, charging several hundreds of dollars. On July 5/2024 I had the vehicle towed to a GMC dealership in lynchburg, va who I had check with and said they could fix it. The first part of September 2024, this dealership advised me the couldn't fix the vehicle. I had the vehicle tow to our companies office in lynchburg. The dealerships are saying they can't get the needed wiring harnesses. Our insurance company had sent an adjuster to the GMC in bedford, va. No warning lamps came on before the smoke. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving and n the freeway around 70 miles and " trailer brake service" message appears on the dash board screen we don't pulling nothing on that time and normally we don't use this car for pulling, the other message appears several times is very frustrating. I am the guy in charge for this vehicle.

Like many other complaints. . When your driving and accelerating it jerks and try’s to change gears ect. Most recent issue is the temperature sensor went out and my fan was running on full speed. Well I got it fixed and within 2 months it has gone out again! lastly, the paint on the hood and roof. When I bought the dealership fixed the hood and yet again it’s failing again. .

The vehicle consistently alerts with service trailer brake system warnings and has progressively become more of a frequent problem with the system doing it constantly even when no trailer is being towed this has been occurring since time of purchase in March 2021 when we purchased the vehicle and has become consistently more frequent over time.

My vehicle randomly locks up and shuts off while I am taking a sharp turn or parking. A 'service stabilitrak' warning flahses on the dashboard. The steering wheel locks and the only way to get this warning to go away is to turn the vehicle off. This is a dangerous hazard as the vehicle can come to an abrupt stop in traffic.

This is a very common problem with gm vehicles produced from 2015 to 2019 and is occurring in 5. 3l and 6. 2l gas engines. The engine coolant temperature sensor is failing and defaulting to a fail safe that turns the electric cooling fans on to full speed because it thinks the vehicle is overheating. When this sensor fails, the engine temperature gauge will not work. When the vehicle is turned off the fans will stay on for 15 minutes at full speed and will deplete the battery. The sensors are being replaced multiple times with different manufacturers and the problem returns in a matter of days or weeks. You can disconnect the battery negative post and reconnect and the problem corrects until it is tripped again at later date. Gm has no solution for this. This issue will leave a driver stranded and will cause engine or transmission issues if driven while the vehicle is doing this. There is no check engine light or code tripped while this occurs either.

There is a special policy to replace faulty tail lamps. However, the policy is only extended through 72,000 miles or 5 years which is ridiculous, and should be a recall. I had my drivers side tail lamp replaced in February 2022 because it was not working. I wasn’t aware of the mileage and year restrictions at that time. Fast forward to today, I have my passenger side tail lamp intermittently working. Now out of the specific time frame, I’m left to encounter this expense out of my own pocket. Clearly gm is aware of the problem, but has not issued a recall on the tail lamp issue. It’s not just a burned out brake light, but apparently an electrical issue with the way they were initially wired. This is a very dangerous situation, as I have no idea if and when my brake light is out. God forbid if they were to go out and I were to be rear ended due to gms lack of taking responsibility.

While driving down the freeway, I received a warning that the charging system was not working and had a red battery light come on on the dash. I exited the freeway trying to get to a safe place, the dash and infotainment system begun to flash on and off. We heard a loud pop, smelt something burning, saw smoke coming into the cabin and then flames from under the hood near where the battery is located.

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.

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.

Both brake lamp assemblies are non-op, no warning in dash and no fuses. GMC #sca n182180270 stating that 2015 and 2016 Yukon. Extended warranty to 6 years or 72,000 miles. We are out of warranty as of last month. $2,500 to replace the tail lamp assemblies. No letter was sent to owners regarding this safety hazard. This should be a recall.

The driver’s side brake light assembly failure of no brake light when brake is applied. It can be inspected upon request. This may cause another driver to not notice intentions to stop or slowdown and cause an accident. This problem is constant. It has not been inspected. No warnings of the failure has been displayed.

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. Thank you, kish martin phone - 210-867-0701.

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.

Led tail light unit continues to crack (metal inside) and not work. Each replacement is over $500. You have to replace or you’ll be ticketed because it is a safety hazard. It is not a bulb replacement it is a faulty design that is costing people thousands to fix and it’s not right. GMC is aware of this defect and they aren’t doing anything about it. Please help and recall these taillights to be replaced by the updated lights!! thank you for your time and consideration.

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 NHTSA 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.

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.

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.

The brake light led panel stopped working on one side and goes out intermittently in the other side.

The contact owns a 2016 GMC Yukon xl. The contact stated while driving, the air conditioner failed to operate. The contact inspected the air condition condenser and noticed that it was damaged and leaking. The contact stated no warning light was illuminated. The vehicle was not taken to a local dealer or an independent mechanic to be diagnosed or repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 71,125. The VIN was unavailable.

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!.

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.

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).

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.

Faulty tail lights. Tail light does not consistently stay lit. This faulty light is going to cause an accident.
