Service Brakes Problems of GMC Yukon - part 2

On two occasions while driving at low speed, my vehicle braked on its on a pulled hard to the left; the stabilitrac indicator also popped on briefly. I went online to determine if there were any recalls on my vehicle and found that one of the recalls on the 2016 Yukon was the exact issue happening with my vehicle. I checked my VIN and found that my vehicle was not one of the vehicles with this issue. I called gm to see if my vehicle had just not been published yet. I explain the situation too the customer service person; she understood my situation and informed me that until my specific VIN in identified with this issue, there's nothing that can be done. I'm thinking that until an accident happen because of this issue, there is nothing that can be done. I read that my issue was a problem with the ebcm, which needs to be reprogrammed. I thank you for any assistance with this issue.

This is the 3rd Yukon I have owned all 2001-2003. Every one of them have had serious brake issues, abs illuminated, parking brake does not work, and light is illuminated, brake fluid everywhere, which when hot starts eating away at electrical components, or in my case at cooling system hoses. Which all lead too one issue after another. I really think that this shoudl be address becasue eveyone I speak with has the same issue. It's exhausting anf expensive too fix, but I have no choice becausei need 3 rows too fit all my children and cannot afford a brand new car.

There's alot of time while I'm driving in line going slowly and break pedal become hard and it will seem like the truck it's not stopping.

On February 14, 2025, my brakes went completely out in the school carline while picking up my youngest daughter. After the incident happened, I saw a light that read "service esc. " this private elementary school is next-door to a private high school. There were students, teachers, and parents walking in this area at this time. I had to maneuver through this carline and away from faculty, students, and parents with no breaks. No individual was injured or killed but it could have been a very serious accident. I called GMC asking for help but was told through a chat line to bring the vehicle in for service. I was finally able to get my Yukon to the service department where after a few days it was determined my brakes failed and they were replaced. One day after I received the vehicle back from service, there was a horrible noise while driving but no lights showed on the dashboard, so it was returned to the same service department. They found metal shavings in my oil and I was told the lifters had collapsed and the engine failed. At this time, I have not heard from GMC and my vehicle is still in the service department.

This has been going on for a while now, but it’s getting worse overtime. If I push on my brakes more than twice the brake pedal locks up and I have to push extremely hard to get my vehicle stopped. . Luckily I have never been going fast and had to worry about this. This is normally when I am pulling into a parking spot or I am backing up that I have to tap on my brakes a few times. A couple of times I have bumped the pole in front of my parking spot due to not having brakes. I just put in a general date as to when they started to get worse.

I have a 2017 Yukon. There is a recall on this model already for a vacuum pump that decreases the power brake assist. My vehicle is having this exact issue. The back tire sounds like the compressor is always running and when braking it grinds at the pedal like a vibration and doesn’t want to stop immediately. I need my vehicle added to the recall list so I can get it repaired.

Good afternoon. Our rental car we picked up from the denver International airport on [xxx] had numerous incidents of emergent braking at highway and non highway speeds which were reported to sixt ( car rental) and documented on the dates in which they occurred, [xxx] (7-8 occurrences ) and [xxx] (3 occurrences-2 after a car wash). On the day in which the first occurrences happened, the car rental company representative from sixt, 3way connected me with a mechanic from annex who advised washing the vehicle to ensure the sensors were clean. I did proceed to wash the vehicle on 1. 25. 25. This same company, annex automotive, then evaluated the vehicle on 1. 29. 25 after emergency breaking occurrences continued of which [xxx] was the worst. On [xxx] there were no vehicles in front of or behind us nor to the sides of us and the roads were completely clear. It was also dark out. Attached you will find evaluation with validation there is a mechanical concern with the vehicle. On [xxx] the extremely unsafe occurrence of emergent braking occurred with skidding tires and the doors locking and unlocking at the same time occurred. This vehicle was completely unsafe to drive. I, as well as my passengers/family, are very lucky the road conditions were moderate on [xxx] and clear on [xxx], or these emergency breaking issues could have caused a serious accident. There were a total of five of us in the vehicle when all of these occurred. I am from minnesota and have a Yukon xl so I am comfortable with this vehicle this was the scariest vehicle experience I have ever encountered. The company did tow the vehicle on 1. 29. 25. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Transmission failed at 100,000 miles stalling vehicle brakes pushing back on me.

The contact owns a 2024 GMC Yukon. The contact stated that while a friend was driving at highway speeds, the vehicle suddenly experienced a loss of automotive power and stalled. The vehicle was towed to the local dealer who diagnosed that the engine had failed and needed to be replaced. No further information was available. Additionally, the vehicle had previously experienced a loss of braking while driving with the cruise control activated. The contact stated that while driving at a slower speed the vehicle lurched forward, striking a gate, and causing damage to the front pumper of the vehicle. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The contact was informed of the NHTSA action number: pe25001 (engine, engine and engine cooling). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 16,000.

My brakes are not working properly. I can be backing up and put my foot on the brake. My truck will keep moving until I apply a lot of pressure on the brake pedal. I can be backing up and my truck will automatically brake and stop moving. I have to cut the truck off, start it back up for it to move. I was in a stand still traffic jam and braking a lot and my truck did stop it keep rolling. Sometimes when I apply the brake it slides. . This is the third time I have put it in the shop. I changed the brakes, brake sensor and replaced tires. I am scared to drive it. My truck is currently in the shop now for the brakes. Please help.

Roughly one to two times per day, a notification pops up on the infotainment screen stating that the brakes need to be serviced due to the brake assist system failing. The vehicle has been brought to 3 different dealerships and none of them know what the problem is, how to fix it, or whether it is safe to drive the vehicle still. The brakes seem to be working fine, however, it is concerning that even if the notification is safe to ignore, the brakes could indeed end up failing and the driver may not be aware due to receiving frequent brake failure notifications per day.

Since purchasing the vehicle in September with 8 miles there have been several electrical malfunctions. Some “fix” themselves when I restart the vehicle and several have needed to go into service. The first issue was when my mirrors wouldn’t come back up when switching to drive. I disabled the reverse tilt option and had it serviced to be fixed. Apparently it needed an update. More recently I had several malfunctions. My vehicle would lower its self while still in gear, and it wasn’t the normal self leveling. I didn’t not have any warning lights or messages pop up. The next time I started my vehicle and had “service rear axle” warning. I called the local dealership and after restarting the vehicle several times and more error messages, I decided to attempt to drive the vehicle in, all the while recovering several message warnings. On the way I was increasingly loosing brakes and I rolled into their parking lot with no breaks. Since this episode I have had repeated lost connection codes without dash warnings. They first attempted to reprogram the brake control monitor. Then when it continued to lower itself and have other malfunctions it went back into service. They replaced the serial data gateway and reprogrammed it. Since then the vehicle is having lost communication codes every day. It is currently in service to try and figure out what’s causing it and hopefully fix it.

I took my SUV (yukon slt 2023) to the GMC dealership 4/5 months ago because of 2 recalls, failed brake fluid leak detection and serial data gateway model. The car was repaired according to the dealership. About 2 weeks ago, I entered my garage to auto start my vehicle and my SUV would not auto start. I waited a few minutes and tried to start it again from inside the vehicle and it started. When it started, the engine light was on and on the dashboard, brake system failure was displaying. It was very strange. So, I let my vehicle idle for a couple of minutes and tried to move the car in the garage. The car started jerking when I put it in drive and a message displayed on the dashboard telling me not to drive my SUV over 40 mph. The brake system failure and engine light were still on. It was very strange. I parked my SUV and let it sit. I'm taking my SUV back to the dealership on Thursday. I'm thankful I wasn't on the highway traveling to work, who knows what could have happened. There are massive problems with these vehicles, brakes, engine, computer systems, etc. I do not feel safe driving my SUV. I drive 41 miles each way for work and I don't feel safe driving this vehicle now with all the recalls, including the engine.

I am the owner of a 2021 GMC Yukon denali with the 6. 2l v8 engine (VIN: [xxx] ). This vehicle has exhibited multiple serious issues affecting safety, drivability, and reliability. 1. Engine noise & oil consumption: since purchase, the vehicle has had a persistent loud knocking/tapping sound, especially under acceleration. The engine also consumes an excessive amount of oil between scheduled oil changes, with no visible leaks. I reported this to the dealership multiple times, but since there is no active recall or TSB, they refused to diagnose or repair the issue under warranty. I have since learned that many other 2021 Yukon denali owners with the same 6. 2l engine are experiencing similar issues and some have had repairs or engine replacements covered by gm. I have received no such support. 2. Braking problems: the vehicle has ongoing brake performance issues. Despite replacing the brake components multiple times, the brakes feel inconsistent and unsafe, especially during highway driving or sudden stops. There is vibration and uneven response, and the braking system does not inspire confidence. These problems have persisted despite attempts to correct them. 3. Suspension/handling concerns: the suspension feels unstable and loose, especially at highway speeds or when turning. The ride quality is poor, and there is noticeable sway and body roll, which creates discomfort and concern for vehicle control. 4. Fuel/propulsion system: the engine does not always respond smoothly to throttle input. I’ve noticed occasional hesitation or surging, which may be related to the previously mentioned oil consumption or fuel delivery. Again, the dealership has been unable or unwilling to resolve these issues without charging diagnostic fees. I’ve reported these issues to my local GMC dealer on multiple occasions, but no lasting solution has been provided, and I have not been able to afford expensive diagnostic costs out of pocket—especially for a vehicle of this price information redacted pursuant to the freedom of informatio.

The component that failed was the camshaft and lifters in the engine - my safety and others was put at risk because while going 45mph, I suddenly lost forward moving power and couldn't go faster than 35 - braking power was sketchy and only responsive when pumped. - I received the following errors on my dash "service esc" "service traction control", reduced acceleration drive with care", "forward collision system unavailable", "service emission system" the vehicle would shudder violently- this problem has been confirmed and corrected at a huge expense (see bill) -.

The contact owns a 2023 GMC Yukon xl. The contact stated that while driving 75 mph coming to an intersection and attempting to apply the brakes, the vehicle failed to stop as needed. The message brake system failure and speed limited to 62 mph were displayed on the instrument panel. The vehicle continued and drove through the intersection. The parking brake failed to stop the vehicle. The vehicle ended up stopping in a ditch and was towed to the dealer to be diagnosed. The contact was informed that the battery terminal had detached, causing 20 different modules to fail. The battery cable was tightened. The manufacturer was made aware of the failure and opened a case for a possible buyback. The manufacturer referred the contact to the NHTSA hotline to report the failure. The failure mileage was 25,100.

Trailer braking system warning is incessantly going off, without cause. Extremely distracting. No way to stop it. Truck has never even towed / trailored anything. Has happened multiple times over the last 6 months. Today occurred 26 times during driving.

This is a complaint for my vehicle Gmc2015 Yukon. My truck brake system(vacuum pump is defective). My large truck is a safety hazard on highway and street . When I attempted to park while depressing my brake pedal it instantly before very hard to press to stop my truck. I have to apply lot of force to my foot inorder to stop vehicle. My mechanic inspected vehicle and it show a bad (defective vacuum pump) . Base on former complaints about this same problem (2019 nhsta campaign number 19v645000 ) it show and state the exact problem with my vehicle. This problem started early last year. Also, when driving on highway and slows down,the brake vacuum pump and brake pedal locks up (very difficult to stop something). This happens intermitting times. Very scary trying to stop from crashing into cars in front of me sometime.

The contact owns a 2023 GMC Yukon. The contact stated that after starting the vehicle, the transmission shifter failed to shift from park. The contact stated that the "braking system", brake pad monitor, and traction control messages were displayed. The vehicle was towed to the local dealer. The cause of the failure was not yet determined. The vehicle was not repaired. The manufacturer was not yet contacted. The failure mileage was 44,871.

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??.

There has always been break problems with this vehicle. Some recalls have been done. Now there is a new problem, I took it to the dealership. There is a special coverage to fix this issue. Gm denied to fix it because the special coverage expired on 06/06/2024. But the vehicle is under the miles and the problem just started.

[xxx] while driving on [xxx] myself and my family in our 2022 Yukon 6 lane highway 65 mph the engine lost power with no warning at all and left us with no power steering ,or brakes. This was in heavy traffic with other vehicles on our right and left side. I was able to put 4 way on and carefully move to the right lane and then barely to the burm. Vehicle would not restart and the sound of it was of rattle and groan. Yukon was towed to the nearest dealer and we were told it was a bad engine of either bearings or rods. We were very lucky to not having an accident and harm my family or other persons on the highway. When a new engine was installed it ran for ony 15 minutes and also was defective for the same issue. Vehicle was returned to us on 12/14/24 and we were denied any additional warranty. At this point I have no confidence in the vehicle or general motors. We took a financial loss when we traded the vehicle because of the major problems thru no fault of ours. The dealer would offer nothing as far as extending the warranty nor would GMC customer service that we filed a formal complaint # [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2019 GMC Yukon. The contact stated that while driving at 55 mph and approaching a red light, the brakes failed to operate upon depression of the brake pedal. The brake pedal had hardened as the contact steered the vehicle off the shoulder of the road. Due to the failure, the contact drove through the intersection and allowed the vehicle to coast to a complete stop. Upon restart of the engine, the "brake assist" warning message flashed on the instrument panel. The contact's husband was called to the scene of the incident and later drove the vehicle to an independent mechanic. The mechanic inspected the vehicle had discovered that the vacuum pump had failed. The vehicle was repaired by the mechanic. The dealer was notified of the failure and offered to inspect the vehicle; the dealer then referred the contact to the NHTSA hotline to file a safety complaint. The manufacturer was notified of the failure but offered no assistance. The failure mileage was approximately 131,600.

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: [NHTSA 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.

Defective wire harness between 2 body control modules, causing alarm to go off repeatedly "service trailer brake system" and also "stabilitrack" will come on randomly and lock my brakes up and all of the features in my dash. This has been very scary to drive and has brought the vehicle close to collision more than a handful of times now.

We just purchased this vehicle from winegardner GMC in prince frederick, MD. On [xxx} on our drive home from the dealership, we kept hearing a terrible screeching/ clucking noise coming from the rear when we were braking or applying any pressure to the brake pedal. We instantly contacted the dealership and they had us bring the vehicle back the next morning for them to look at and to make the repairs but unfortunate for us. They do not have the parts in stock, so we have to take it back Tuesday, October 8 , 2024 at 8am and leave it for the day. Hoping it is repaired correctly with the new parts “both rear calipers” as I left the dealership, I was approximately 10 miles away and out of no where my dash displayed “service, trailer, brakes”, constantly along with a loud dinging noise for the rest of the drive home. I contacted the dealership and spoke with the service manager and informed him of the situation. He told me it has been an ongoing issue with gm for years and it’s electrical and because we purchased a used vehicle. It’s not covered to be repaired. We would have to pay out-of-pocket for it to be fixed. This is very upsetting because we just spent $40,000 on a used low mileage Yukon denali for our family to travel in, but it’s unsafe, because it affects the traction control, and abs brake system. I would also like to note that I did not have a trailer hooked to the vehicle, so I do not understand how that service indicator would appear unless it was cleared by the dealership during maryland state inspection. We have asked them several times for a copy of the maryland state inspection they performed, and we are getting the runaround. As the purchaser of a vehicle, it is all right to have that document, showing what past and what failed maryland inspection before being resold to us.

I have noticed the amount of pressure needed to apply brakes at a slow speed is a lot to where it seems like I will crash into the car or object in the way of my vehicle. I took my vehicle to a GMC dealership and was told the brake vacuum pump needs to be replaced. These vacuum pumps were already recalled by NHTSA. Nhtsa #19v645000, gm #n192268490. This recall was expanded to include additional vehicles. Nhtsa #20v603, gm #n202300860. I strongly believe my vehicle needs to be included in this recall. GMC repair invoice is attached.

My power vacuum brakes system is not properly working. In order to stop truck I must depress brake pedal very hard just to stop truck. Crunching noise every time. Made several trip to mechanic . I changed many part ( brakes) rotors , still and brake vacuum sensor ( purchase from GMC dealer . Still have this problem. Mechanic states, need new vacuum pump. Very dangerous to drive. Very difficult to stop . Please investigate this VIN for common complaints.

The contact owns a 2023 GMC Yukon. The contact received notification of NHTSA campaign number: 24v674000 (service brakes, hydraulic); however, the dealer refused to perform the recall repair because the vehicle had a salvage title. The contact stated that the dealer would repair the vehicle but only if he paid out-of-pocket for the repair. The contact stated that the dealer had exceeded their authority in declining to complete the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Transmission failure, hard shifting, slipping and loss of power also severe shuddering. Very dangerous driving. I had to have the transmission replaced after taking the vehicle to a dealership and upon verification from same dealership reproducing the transmission failure. Massive financial loss, dealership stated these transmissions are known to fail. Manufacturer has been notified by numerous complaints. Compensation is warranted.

I keep getting a warning on my display on dash about my trailer brake system is not working. Also my temperature gauge stops working and I have to take off negative cable on battery to reset it. Temperature control sensor has been replaced but the problem still continues to happen.

On [xxx] I brought my vehicle to rivard Buick GMC with a squeaking noise that was check and attempted to be repair four times at the same location. They provided a quote for $2,309. 10 stating it was the master cylinder. Rick the services director said it was not cover under warranty and it need it to be cover by me, at that point I explain to him the vehicle has been in and out of his services department for the same issue since it had 20,000 miles. 1st time-they replaced the front brake pad stating gm had a defect on them (noise went away for a few thousand miles) 2nd time- they apply conditioner to the brake and lubricant so they say (noise went away for a few thousand miles) 3rd time- they said it was not the front brakes anymore making the noise. They said warranty did not cover rear brakes due to gm not flagging it as defected pad. I complained the noise was coming from the front of the vehicle but they insisted it was the rear so I paid $500 plus to get the rear brakes at 60% life left on them. At the time of picking up the vehicle after repair completed the noise came back within a few miles from the dealer. I returned to the dealer and spoke with the services manager troy, he apologized for the inconvenience and said they will take care the front brake at no cost to me, however they submitted a claim to gm to get the work done and kept my money when they misdiagnosed the issue. 4th time- noise comes back at this point the warranty it's expired and they tell me it's the master cylinder the actual issue. When I talked to rick, he said that gm was willing to pay for half of the work and the other half it's my responsibility. On [xxx], my wife and three kids almost hit a wall while trying to stop and the braked did not work. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving back from las vegas for a family trip, traffic was heavy, a lot of stop-and go. I started to feel the brakes delay to stop. After a few minutes I was able to pick up a little speed and again traffic was built up. This time the brakes failed and got stiff. I had to slam on the brakes and practically stand up on the brakes in order for the car to stop. I barely avoided wrecking into the car in front of me. I was a few hours away from home and had to drive all the way with this problem. When I got home I took it in to the nearest dealer shop to get the brakes checked . I looked online and found out about the recall on the brakes.

While I’m parked or even driving I keep getting a alert on my speedometer ( trailer break system ) and it’s not a 1 time alert the whole time I’m driving it’s constantly alerting me yet I don’t even use my trailer system at all, it’s concerning due to the distraction of trying to clear the screen constantly while I’m on the high way.
