When driving through Eugene brakes suddenly got soft while at a stoplight, then pedal got stiff and very hard to keep pressed. An alert came on the dashboard 'Brake Assist Service' just about the same time the brake pedal changed and car would not fully stay at a stop. When checking to feel what had just happened, by letting up and repressing the brakes, it would not fully stop car, even with all my strength pressing. If another car would have been coming through, my young son or myself could have been killed or seriously injured and I could cause someone seriously to be hurt or killed from being in their lane of travel. I alerted my husband that I was unable to drive the vehicle safely, he is in the vehicle industry and looked up online and found there is a common known problem, recalls, and service bulletins, but apparently not for vehicle years prior to 2017, although this severe failure is seen on 2014 and later; and the manual tests/diagnostics that a person can do in a pinch per the bulletin, recall notice, and articles; and in his trials of how to tell if it is a failure or fleeting problem - nothing alleviated it, all the symptoms are present and system is failing and continually bringing up the brake assist service alert. This is the info that we found on the recall, but didn't appear to cover 2016 year models: [the federal safety agency campaign number: 20V603. GM's own number for this recall is N202300860.] We plan to get this yukon over to Guaranty Chevrolet in Junction City Oregon tomorrow 10/8. The only thing that has been very recently noticeable preceding this in recent week or so is a slight uneven braking feeling in the motion of the car when coming to a stop. Which it has not done before.
2016 GMC Yukon brakes complaints
Page 2 of 3: complaints 11 to 40 of 55, newest first, as owners wrote them.
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.
Brake light keeps going off and on it’s like a short but when checked everything is connected
During standard braking operations the vehicle (not a hard emergency situation) on dry ground the vehicle seems to activate the abs system or something similar which makes the braking effort non standard and increases stopping distance. The issue has occurred occasionally for over a year but is becoming more frequent. It has occurred at both highway speeds of 55 mph and almost stopped during parking activities of 2mph.
GMC is stating that due to a recall my brake booster vacuum pump failed and now they are that is is not covered and I will be out of pocket on the issue after numerous phone called with GM they are still of no help and the vehicle is not safe to drive which is my only means of transportation
My 2016 GMC Yukon is hard to stop when pressing brake pedal. Vehicle shimmy’s when pressing the brake and it must be pressed very hard. Have read and watched many videos this is very common issue on 2014-2018 Yukons and Tahoes. This could be very dangerous and my question is, why has these vehicles not been recalled to prevent accidents when it seems to be a common issue and expensive to fix?
“Service Trailer brake system” warning continually going off when driving
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
Brakes will randomly stop working. When the brakes are pressed you have to press all the way down and then vehicle still won’t stop and the only way for the vehicle to come to a complete stop is to press the parking brake. Brakes and rotors have been replaced already and it still happens
When I was merging on the fwy my car accelerated and I couldn’t slow it down. I had to get off the fwy and break really hard. Driving on the fwy and not being able to control the speed or breaks could of caused an accident or cost us our lives. I have an appointment with the dealer service center on Sept 20, 2022. A few weeks ago I noticed the car was having trouble sifting gears.

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.
2016 GMC Yukon. I received a letter that stated my Yukon may have a condition where the brake lights intermittently do not illuminate. In March 2020 the drivers side rear brake light did not illuminate. I brought it to a Chev/GMC dealer that replaced the tail light no charge. Now my passenger rear tail brake light does not illuminate. My Yukon has 68800 miles on it and it is going on 6 years old. I still have my letter I received about this issue. Without my tail/brake light it is unsafe to drive my vehicle until I get that brake unit replaced. Will I still be able to my passenger side brake unit replaced at no charge? I haven’t been able to get it replaced due to I had total knee replacement surgery in February 2022
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 trailer break service light is coming on. There is not a way to dismiss the sound and comes on every few seconds, it's very distracting a HUGE safety risk. I have contacted GMC Valencia California and they have have several vehicles with the same issue / hazard. This has apparently been going on for years yet GMC refuses to put a recall on the vehicles nor take action on correcting this on this critical issue. This is very upsetting and with all the complaints / concerns it appears nobody cares for the lives this defective issue could cause, especially when towing. Thank you.
The contact owns a 2016 GMC Yukon. The contact stated that while driving at approximately 70 mph, the brake pedal was hard to depress and the brake pedal traveled to the floorboard. The contact mentioned that the brake pedal needed to be pumped in order for the vehicle to be operated. In addition, the contact stated the vehicle failed to stop immediately. The vehicle was taken to a dealer where it was diagnosed that the brake line needed to be flushed. The vehicle was repaired however, the failure persisted. The vehicle was taken to an independent mechanic where the failure was undetermined. The contact mentioned while the mechanic was reversing the vehicle the brakes failed to operate causing the vehicle to crash into a person and a vehicle. The contact stated that the lady sustained multiple injuries that needed medical attention. A police report was filed. The vehicle was towed to the dealer where it was diagnosed that the brake vacuum pump needed to be replaced. The vehicle was repaired but the failure recurred. The vehicle was taken back to the same dealer where they informed the contact that the failure was unable to be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage 54,000.
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!
Vacuum pump loses vacuum, and the brakes are very hard. Occurs when sitting still with the brake applied. Also occurs in reverse at low speeds. My wife refuses to drive her car, due to numerous near fender benders.
The AC won't blow cold. The brakes aren't stopping the vehicle.
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.
Brake lights cuts on and off when driving and third brake light is off on my 2016 vehicle also when step on brakes pedal sometimes goes to floor vehicle hard to stop a for sure dangerous situation
On two occasions while in a drive thru line, I would press the brakes and the brake pedal would go to the floor. I had to basically stand up on the brake pedal to get the vehicle to stop. I have not had this happen other than at a low rate of speed. I searched gmc yukon for any recalls and found that this is a recall with gmc. When you do a search of my vehicle by VIN, it states no recalls are found. I contacted a local gmc dealer and was told that they can't do anything unless my VIN shows the active recall.
Tl* the contact owns a 2016 gmc yukon. The contact received a letter from the manufacturer which suggested that the vehicle needed to be diagnosed in regards to the rear brake lights operation. The vehicle was taken to covert buick gmc (11750 research blvd, ste d, austin, tx 78759, (512) 371-6075) to be diagnosed. The contact was informed that there was no failures or issues found with the rear brake lights. The dealer disregarded the letter after inspecting the vehicle. The manufacturer was not contacted. The contact stated that the issue recurred after the vehicle was returned to her custody. The vehicle was taken to an independent mechanic and the former diagnosis was confirmed. The vehicle was not repaired. The contact stated that the same dealer declined the purchase of the part needed to fix the vehicle. The failure mileage was 77,655.
I purchased my truck from gilroy chevrolet in september 2019. The week we bought it my husband had to change the breaks as they needed to be changed. Shortly after within a week from that we started hearing a popping sound from the left front part of the truck. Somewhere near the axel or tire baring. I contacted the dealer and stated they had sold me a car with no breaks and with this mysterious noise. They diagnosed the car, charged me and didn't fix the problem I didn't even get reimbursed or an apology for being sold a car that had no breaks. I have taken my car to a new dealer for further diagnosis. Where they are asking me to pay for a diagnostic fee and deductible I feel the original dealer who sold me this defective car should have to pay since I have paid these due once already. Any time the steering wheel is turned all the way you feel and hear the popping noise.
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. While accelerating from a stop, the vehicle jerked and accelerated independently without warning.
