LED Tail Light out

- Milwaukee, WI, USA

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.

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 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.

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.

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.

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.

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 Yukon 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.

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)
