My engine has metal flake in it and once which is a sign of engine failure. I reported it to GM they said it was a normal amount and to keep an eye on it the next day toil change. They issued a recall on the 6.2L motors and they have not on the 5.3L motors and this one is doing the same thing. I want to get ahead of the ball before my engine give out on the highway but GM is treating it like it’s not a big deal.

Months ago I took my car to the dealer for the engine failure recall and they said there were no issues and changed the oil to a higher viscosity oil. Today I was driving and my engine failed while turning onto a busy road and took multiple tries to get started. It finally started and the engine light was flashing. The dealer told me th flashing engine light was bad and to not drive at all. I pulled over and had it towed to the dealer. The engine light stopped flashing. The dealer said they pulled a code on the computer and would look at it. They had my car for a full day so far and have said they can't find an issue. I do not feel safe having my family in this car when the engine can fail and they say nothing is wrong. I am lucky that I wasn't hit at the location it failed at.

Was driving approximately 70 miles per hour on the highway. While driving the vehicle just stopped in the middle of the highway after going 70 miles per hour. Was unable to put car in park. Car just shut off. Four police cars had to surround car due to being stuck in the middle of the highway with my small child in the car. Took an hour to get a tow truck. Being told our engine is now completely shot.

On September 4, 2025, I brought my 2023 GMC Yukon Denali in for the product safety recall regarding the engine. My engine passed the recall inspection and I was given an oil change with high grade synthetic oil. This past Saturday, March 7, 2026 as I was driving in Tampa Florida with my [XXX] son, my Yukon experienced catastrophic engine failure and I lost all propulsion control. The car went into neutral and I pulled along the side of the road safely to avoid an accident. As I put my car into park, the engine shut off completely and would not turn on again. There was no clicking sound and no attempting to turn over. I contacted roadside assistance and they sent a towing company to bring my Yukon to Century Buick GMC in Tampa Florida. The symptoms of what happened are similar to those of the recall. The dealership is replacing the engine however this is a critical safety issue as my son and I could have been severely hurt and or killed. Please investigate.

The engine failed and had to be replaced with less than 70,000 miles on it. There has already been a recall associated with these vehicles where a part is either replaced or special oil has to be used. It does not seem that the fix prevents the engine from failing.

Vehicle developed hesitation. Message: "Reduced Acceleration Drive with Caution" Check Engine light comes on, fortunately near home. Scanner showed "PO 0747 Transmission Valve #1 stuck open." Research shows this is a common problem and a safety issue and can leave driver stranded or worse. Had vehicle "serviced" at selling dealer, but they did not touch the transmission. Said they drove it around the block and it was fine. Image attached. I was then told that parts are not available and GM will not authorize swapping out the valve body. Forums posts show a lot of dissatisfaction with GM over this issue.

the Engine started running rough and the engine light came on. The dealer told my wife to drive there in limp mode (~15 miles), she did so on back roads. The diagnostics said that cylinder 7 was not firing and teh fuel injector control circuit was bad. they had to replace the Engine Control Unit.

The contact owns a 2023 GMC Yukon. The contact stated that while driving 75 MPH and depressing the accelerator pedal, there was an abnormal clunking sound coming from the front of the vehicle; however, the contact was unsure if the failure was coming from the engine or transmission. The contact pulled over to the right side of the road, exited the vehicle, and inspected the vehicle, but found no failure. There was an unknown warning light illuminated. The contact stated that the failure had occurred on four occasions. An unknown dealer was contacted. The vehicle was taken to a dealer, where it was diagnosed, and determined that the valve body needed to be replaced. The valve body was replaced. The manufacturer was not notified of the failure. The approximate failure mileage was 33,395.

On April 30, 2025, my 2023 GMC Yukon with 68,000 miles on it (8,000 miles outside of the warranty and that I had purchased on 4/27/2024) randomly downshifted as I was turning into a parking lot and gave me a computer notification stating "Service transmission now, unable to shift soon." I immediately put my car in park and called OnStar for her to read me the computer code. She said it came up with two codes so we brought it to Wyatt Johnson GMC in Clarksville Tennessee. They plugged in their computer reader and that's when the service provider informed me that my car was un-drivable because it was unsafe. We left it there for them to do a diagnostic test on it to see exactly what is wrong with it. A few days later they contacted us and informed us that it was a malfunction in the transmission valve body. The dealership informed us that it would cost $2754.25 to fix but the issue is the part is on back order and they don't know when it will be available. We have been in contact with the dealership and with General Motors customer service almost weekly trying to find out, when the part will be available and where I am on "the list" and no one has an answer. With the personal research that I have done, I have seen that people have been waiting for over a year. I also know that there are current class-action lawsuits for GM's Yukons for years a little older than mine and currently multiple complaints for the newer Yukons for the same transmission valve body issues. The dealership does not give out loaners anymore after Covid. I have asked, general motors. Customer service has informed me that it's up to the dealership if they will give me one General Motors said they would look into a possible reimbursement program if I have to purchase a rental, but they will only cover a car that cost $44 a day and that is not including taxes and extra fees, but I can't afford to rent anything and I'm missing work.

My name is [XXX] , and I am writing to formally lodge a complaint regarding a serious safety defect in my 2023 GMC Yukon with a 3.0 Duramax diesel engine. The issue involves the transmission valve body, which has caused rear wheel lockup at highway speeds. I experienced this issue at 34,000 miles on my vehicle, and it has been in the shop for over 5 weeks with no estimated time on parts availability. Despite opening a case with GM support, as detailed in the attached email transcript, I have not received a resolution. GM has refused to replace the complete transmission on the vehicle and only offered to replace the valve body. This is unacceptable as the defective valve body has already caused damage to the transmission. I also opened a BBB Auto Line case, which was closed immediately after I denied the offer from the GM support representative. This raises concerns about a potential conflict of interest, as the BBB Auto Line seemed aware of my interactions with GM support. I am seeking a complete transmission replacement with a valve body upgrade kit from NextGen transmission, which I believe would resolve the issue. However, GM has not accepted this offer. I request that the NHTSA investigate this matter promptly to ensure the safety of my vehicle and others that may be affected by this defect. If this issue is not resolved, I will have no choice but to pursue legal action. Thank you for your prompt attention to this matter.

The contact owns a 2023 GMC Yukon. The contact received notification of NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the part to do the recall repair was not yet available. The contact stated that while starting the vehicle there was an abnormal sputtering sound coming from the engine. Additionally, several attempts were needed to start the vehicle. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was unknown.

I am writing to formally express my concern and frustration regarding the prolonged delay in implementing a remedy for General Motors Safety Recall N252494000, which affects vehicles equipped with the L87 6.2-liter VB engine. This recall, issued in April 2025, was prompted by serious safety concerns involving sudden engine failure and loss of propulsion-conditions that significantly increase the risk of a crash. Despite the recall being acknowledged and a Special Coverage Bulletin (N252494003) issued in May 2025, there has been no clear timeline or actionable fix provided to affected vehicle owners like myself. The root causes, as identified by GM, include rod-bearing damage due to sediment and out-of-spec crankshaft dimensions-both stemming from supplier manufacturing defects. Given the severity of the issue and the number of vehicles involved (nearly 600,000), the lack of timely resolution is unacceptable. I urge the NHTSA to take further action to ensure that GM expedites the development and deployment of a permanent fix. Vehicle owners deserve transparency, accountability, and above all, safety.

The 6.2L motor in my GMC Yukon failed due to the camshaft and stalled me in an intersection on a highway. Had to shut the lanes down to get towed. Lost all power and couldn’t do anything but sit in the road. Just did a PICO test and it “passed” but failed 3k miles after the recall was done.

Mar 22, 2026

I just survived a terrifying incident that proves the current GM 6.2L (L87) engine "recall fix" is a dangerous myth. Living with the "Ticking Time Bomb" I bought my 2023 GMC Yukon AT4 brand new, but for the last two years, I haven't truly "owned" it—it has owned me. Every long-distance trip with my family was filled with anxiety. I constantly worried that I’d be the next one stranded on the side of the road while my neighbors' and friends' 6.2L engines were seizing all around me. I traveled with fear that I’d be coming home in a rental car. The False Security of the Recall When the recall finally arrived, I thought the nightmare was over. On Sept 15, 2025, my dealer in Newburgh, NY, inspected the truck at 48,000 miles. They told me my engine "passed," switched the oil to 0W-40, and issued me a 150,000-mile extended warranty. I realized then what I know for sure now: 0W-40 oil is a band-aid, not a cure. GM used thicker oil to "cushion" a physical manufacturing defect in the crankshaft and bearings just to avoid the multi-billion dollar cost of engine replacements. They traded my family’s safety for their bottom line. The Catastrophic Failure Last Friday, March 13, 2026, the "fix" failed. I was traveling 70 mph uphill on I-84 with my **newborn baby** and two other kids in the back. Without warning, the engine seized solid. I lost all propulsion in heavy traffic and had to fight to get my children to the shoulder. We sat in the freezing cold for over an hour while traffic flew by us. An extended warranty is worthless when your engine dies in a high-speed traffic lane with an infant in the car.

The vehicle drove fine had no warning/ check engine lights. My girlfriend came up to a busy intersection and when she proceeded to cross the intersection the vehicles motor locked up stopping the vehicle in the middle of the intersection with traffic coming from both north and south direction. We had poor visibility due to blowing snow so she had to bail from the vehicle and stand on the side of the road so she would not be harmed if the vehicle was t boned. Vehicle stopped so hard and fast it threw her into the steering wheel. Was unable to get the vehicle restarted and could not get it to shift into neutral so vehicle blocked 1 lane of traffic completely and half of another lane until tow truck arrived to remove from road.

Vehicle was brought to dealership Fountain Buick GMC 8701 S Orange Blossom Trail, Orlando, FL 32809 (866) 465-4364 for recall on engine. Dealership told our company that they were unable to repair or diagnose the recall this month June 2025. Vehicle has had an intermittent check engine light from time to time. I was instructed that it was safe to still drive the vehicle.

On March 28, my 2023 Yukon Denali stalled on a 4 lane road forcing me to make an emergency stop on the side of the road in a right hand turn lane. The vehicle required towing to a local GMC dealership. They could not restart the vehicle and upon evaluation found metal shavings in the oil. They have recommended an engine replacement. There was no warning, it just stalled and would not restart. My Yukon remains at the dealership and we are still waiting for an engine.

My vehicle experienced a sudden and complete loss of OnStar and telematics functionality during or immediately following a routing/software update. I had taken my vehicle in for my engine recall and noted another software update was required and specifically was told by multiple service members over the phone that the onstar services/telematics module was impacted and this update should resolve it. After some initial research it appears this is related to N212331730, which impacts OnStar and telematics services. I brought the vehicle to an authorized GMC dealer for the recall. After inspection, the dealer informed me that the telematics control module has failed and must be replaced. This failure resulted in the loss of all OnStar safety-related services, including emergency response and vehicle communication features. The failure appears directly related to the recall condition or software update process, yet I am being told the module replacement is not covered. This creates a safety concern because emergency communication systems required for crash response and roadside assistance are nonfunctional. I am concerned that the recall remedy may be causing or accelerating telematics module failures and that affected vehicles may be left without critical safety systems unless owners pay out of pocket.

we brought my 2023 gmc yukon into Parks GMC in greenville sc on july 26, 2025 for the engine recall that we received a letter from. We left it as we were going on vacation for the week and picked it up the following saturday august 2nd. the next week my engine light started lighting up and my husband contacted the dealership and we were asked to bring it back in. We did and were told that we now had a bad Telematics Communication Interface Control Module that was causing my engine light to come on and that we were going to have to pay $600.00 out of our pocket to have this repaired. After researching we found that this is a VERY common and widespread problem with a lot of owners right after they bring their vehicles in to be serviced. We declined the repair, one because they did not have the part in stock as that apparently is also a big problem of not being able to get the part in stock and two because we feel like we should not have to pay to have this part replaced as it appears to be a widespread issue that is happening. The dealership also charged me $182 for diagnostic charges that I once again feel like we should not have had ton pay.

onstar telematic module failed. dealer stated it shorted internally. upon researching online this is a pretty common issue. this module is important to safety as it can detect & report crashes, help get first responders on scene in the event of a crash, etc. my vehicle was less than three years old and had an active onstar subscription at the time of failure.

Electric trailer brake control module intermittently disabled trailer electric brakes while towing electric brake equipped trailers. This is the same issue addressed in GM service bulletin N232414840 which addressed a similar issue associated with GM pickup trucks. The loss of trailer brake utilization may create a safety hazard resulting from longer stopping distances. The factory control module was replaced with a redesigned module purchased from GM and the problem went away. I am of the opinion that the factory-provided module is a deficient design which warrants replacement by the vehicle manufacture.

Injuries: 2

The Onstar module becomes inoperable due to a fault with the onstar module. This is a known issue on many forums and GM has yet to issue a fix with mass reported Onstar module failures. This fault renders useless the safety systems.

My 2023 GMC Yukon Denali with the 6.2L V8 suffered a sudden loss of propulsion while traveling at approximately 70–75 mph on the highway with my wife and young daughter in the vehicle. The engine RPM dropped immediately to zero and the vehicle displayed a message instructing me to press start. I do not recall any meaningful prior warning lamps or symptoms before the failure. I did not hear a loud bang or other dramatic engine noise; the vehicle simply lost power and would not continue driving under engine power. I had to coast across lanes/shoulder to a stop, which created a serious safety risk to my family and other drivers because the vehicle lost propulsion at freeway speed without warning. After stopping, the vehicle would not restart. Pressing the start button produced only a click from under the hood and the engine would not crank. The vehicle was towed to a GMC dealership in Victorville, California. The dealer has since confirmed that the engine requires full replacement. The failure has therefore been confirmed by an authorized GMC dealer and the vehicle should be available for inspection through that dealership/manufacturer if requested. This is especially concerning because this vehicle was already part of the known GM 6.2L recall population and had supposedly passed the recall inspection/remedy before I purchased it. Despite that, the engine still failed catastrophically only about 1,355 miles into my ownership. Purchase mileage was approximately 26,343 and failure occurred at approximately 27,698 miles. Based on what the dealer told me, the failed component/system is the engine assembly.

My engine failed while I was driving & I had no warning. It was very scary & dangerous. Luckily I was in an area where I could get off the road quickly. It started skipping then lost power. I basically coasted off the road & had to call for help. It was making a bad knocking noise. This happened 2 weeks ago on April 16. It has been sitting at Glynn Smith.GMC dealership since. I was told by the service manager that the engine failed & I will need a new engine. the engines are on back order now. I fear they will replace it with the same problem. I see the recall this week but will changing the oil viscosity really fix it?? Doubtful. Someone is going to get killed or hurt from this problem. I do not want the same issue to happen with a new engine.

2023 Yukon Denali has now broken down twice, leaving myself and my family (husband and children). This last time was on Friday 1/16/26 while we were out of town, the car began malfunction and then we had complete engine failure while drive 70mph down the highway, again, leaving my family stranded on the side of the road, on a busy highway, in an unsafe environment in the winter.

Recall for engine propulsion. Say that there is no remedy yet. I have read the warnings about what may happen and I am terrified to drive the vehicle. GM says to contact the dealer, dealer says to contact GM. No one wants to take initiative. If they cannot fix the car, they should buy the car go back so I can get something different. I have been driving an old car around because I’m am afraid of this one. Please help me.

I was driving on the highway going about 50 mph and the engine just stopped. It was very dangerous, and I couldn't get to a completely safe spot. I was stuck for 45 minutes there until police could get to my Yukon and help provide safety. I had 2 other passengers in the car. All of us were put at great risk and the surrounding traffic was also at risk. The Triple A towing took over an hour to get the vehicle on a flatbed because they couldn't get the Yukon in Neutral. There were absolutely no warning lights or any weird noises, the car shifted out of drive and would not go back into any gear. I am waiting for the dealership to decide what to do. My main reason for writing this complaint is this is a BIG HAZARD, not only for people who drive/ride in these vehicles but for every vehicle on the roads around them. When they stop with no warning, accidents and I'm sure some with fatalities will happen. This is a critical situation, and these vehicles should all be off the road. My Yukon was in my dealership service for an oil change about 1 week prior to this incident and I had a long conversation about the recall. They said my Yukon looked great and nothing was needed unless I had any problems. Since there have been so many others with the failed engine, ALL vehicles with this recall should be off the road to prevent totally innocent people from being in these dangerous situations. This is preventable if these cars are forbidden on the roads!!! GM must take responsibility before lives are lost due to this negligent reaction of issuing a recall but saying it is safe to keep driving unless there is a problem. If the first sign of a problem is failure with resulting catastrophic outcomes, then just issuing a recall is not enough. This must be addressed, PLEASE. This was a terrifying experience for me and my riders. I have no idea if the police filed the report but they spent alot of time trying to keep everything safe due to this issue.

I own a 2023 GMC Yukon Denali with the 6.2L V8 engine. A safety recall was recently issued for this vehicle due to a potential engine defect that could result in sudden and severe failure. However, GM has not provided a remedy, and dealerships are unable to offer any repair or trade-in options while the recall remains open and unresolved. I live in a rural area with limited cell service and long distances between towns. This makes the potential for sudden engine failure even more dangerous. Out of serious concern for my family’s safety, I no longer feel comfortable allowing my wife or our [XXX] child to ride in or use the vehicle. The risk of being stranded—or worse, getting into an accident due to engine failure—is too great given our location and the nature of this defect. I attempted to trade in the vehicle at a GMC dealership to get into a safer and unaffected vehicle, but the dealer refused to accept it because of the recall. This leaves me stuck with a vehicle that has a known safety issue and no solution in sight, limiting both my transportation options and peace of mind. There were no warning lights or prior symptoms before the recall. The issue was disclosed by the manufacturer. A dealer has confirmed the recall is active, but no fix exists. This situation is unacceptable and has real-world safety and financial consequences for families like mine. I urge the NHTSA to hold GM accountable and ensure a remedy is made available immediately to protect consumers who are left in limbo by this unresolved and serious safety defect.

My vehicle started making a terrible noise. I had it towed to the nearest GM service center. It was determined that the vehicle, a 2023 Yukon Denali (less than 26000 miles) needed a new engine due to thrust bearing failure causing the engine block to be scored and contamination of debris internally.

On 3/3/2026 during the night-time hours, I was traveling on the freeway in my 2023 GMC Yukon at over 65 MPH when I received a notice from the instrument cluster stating that the battery was low and oil pressure was low. Before I could pull over to a safe location, the Yukon turned off while in motion. My wife and two children were in the vehicle. The Yukon stalled in the number one lane of the off-ramp. I had to remove my children and wife from the vehicle while in the roadway on busy throughfares and in darkness. I attempted to jumpstart the Yukon, but efforts were unsuccessful. The Yukon was towed to the dealership where I purchased it purchased from. The Yukon was returned to my custody on 3/10/2026 stating it was an issue with the battery. While driving the Yukon home it began to bog down and stalled out in-front of my residence as it was being driven by my wife. After arriving home (night-time), I went to check the Yukon, and it started with no issues. I drove the Yukon to see if the errors would occur again. While driving the Yukon on the freeway, the Yukon RMPs indicated close to redline and I received a notification from the instrument cluster stating to turn the vehicle off (traveling at about 70-75 MPH). Once again, I was unable to pull off to a safe location before the Yukon turned off on its own while still in motion; I attempted to jumpstart the Yukon but attempts were unsuccessful. The Yukon was towed again to dealership. On 3/11/2026 I was advised that the engine had seized and on 3/13/2026 I was advised by GMC the engine needed to be replaced (this was covered under powertrain warranty). The approximate milage of the vehicle is at about 42,200.

Approximately 14’000 miles we were told a rod went through the engine. Our vehicle failed at a high rate of speed leaving myself, wife, and 2 young children to pull off a major highway and call for police to help slow traffic. This happened while driving 70 mph on the highway. The only warning we received was when the car went from “D” drive to “N” neutral on the highway. Fortunately, we had enough time to pull to the side of the road before complete engine failure. GMC road side was not helpful. We were told we would have to find a ride home over an hour away, and when our ride arrived, so did the tow truck. Then, they had to drag the vehicle onto the flatbed because the tow truck company did not have the unlocking device for the wheels. Upon getting it to our house, the tow truck company had to rock our vehicle off the bed! We were not able to tow it where we purchased it. We either had to tow it to the nearest GM dealer or our house. We chose our house because the nearest GM dealer from where we broke down would've been over an hour away from our house. Our second engine failed 2200 miles later while my wife was sitting at a light in a busy intersection. The car again went from “D” to “N,” and it was immovable. The cops had to be called because the tow company couldn’t come fast enough. We were towed out of the intersection, but I waited over 5 hours with several dropped tows for a tow company. That occurred on my birthday. We are now on our third engine, and GMC wouldn’t warranty the engine. Our brand new tires went at 32,000 miles because GMC could not confirm or deny that rocking our vehicle on and off the flatbed three times didn’t affect the alignment. The front two tires inside tread was worn. I was told the tires from the factory are 50+ thousand mile tires. We barely got 32,000 miles. We’ve had multiple issues with electronics, back up camera, and media package. The Lemon Law won’t cover us because our first engine did not fail before 12,000 miles.

8/26/2025 I purchased the vehicle from Maguire in Syracuse, NY with open recalls. It is my understanding a dealership is required to have these fixed prior to selling a vehicle. I now have to drive 45 mins each way to get them fixed and miss additional 2 hours for wait time from work. Brakes could fail causing an accident.

My wife was driving in the vehicle with our two (2) infants on Dixie Hwy in Boca Raton, FL when the breaks suddenly stopped working. Fortunately, there was not a lot of traffic on the road at this time and eventually the vehicle slowed down and no one was injured. No warning lights came on. Once the car came to a complete stop my wife turned off the vehicle and started it back up; still no warning lights or anything. My wife drove a little further to get to a safer location (not in the middle of the road), unfortunately the car then completely stopped working and my wife was still stuck in the middle of the road...eventually a police officer (crash inspector) came to the scene and the car was towed to the dealership for repairs.

SEATS

2 complaints

After GMC completed 4 recalls recently, my drivers side seat lumbar support started automatically inflating to the highest setting, as well as the shoulder support. I could not deflate the shoulder support at all, but could deflate the lumbar support, but had to do it every single time I got in the vehicle. After they did additional recalls about 30 days later, the issue got worse and often times I'm unable to deflate the lumbar support at all, making driving extremely uncomfortable and what I would deem slightly unsafe given how inflated the seat is. The fact that the 2nd set of recalls made this situation worse makes me suspect it's related to module updates as opposed to my particular seat. Now I am on the hook for a $1200 fix. 2 different GMC locations did the recalls.....I do not blame either of them, I believe this is a defect GMC should look into asap given they have had similar seat issues in the past.

Nov 11, 2025

The headrest in the 2nd and 3rd rows of the 2023 GMC Yukon are not adjustable or removable, reference page 39 of an owners manual. This is a major problem when installing car seats into the vehicle. Because of the design, the headrest tilt forward and do not allow car seats to properly sit against the back of the seats. This causes a gap between the back of the car seats and the seat back of the car. I have 4 kids and 3 different types of car seats. All of the car seat manuals say that for proper installation the car seats must seat flush with the seat back of the car. Well this cannot happen because of the design of the vehicle. Therefore I cannot properly install car seats of any type into this vehicle. I am not the only consumer with this issue as it is all over the internet as well. I have called GM corporate and they are not willing to address this safety concern as it would require a design change. I have attached pictures of 2 of the seats which have a gap between 2-5 inches depending on the height the car seats are set at.

The front windshield wipers suddenly stopped working and will not turn on.

May 22, 2025

Serious Safety Issue: While driving in the Rain, with the wipers on (actively working), randomly they will stop working. They will not work again until 10-15 minutes of time has passed. Any alternative setting makes no difference. During the 10-15 minutes of non-working wipers, there is nothing the driver can do…. Except wait. Depending where and when this occurs, this could be a deadly safety issue. I’ve checked the fuse; Turned off the rain auto-sensing feature – yet the vehicle is scary to drive in the rain, not knowing if / when the wipers may stop working again. During my ownership of this vehicle, this has happened three times; of course you must be driving during rain for the issue to occur.

Problem Synopsis: Camera Issues in 2023 Yukon Denali Vehicle Information: Model: 2023 Yukon Denali Issue Description: The vehicle's camera system exhibits malfunctioning behavior after the vehicle gets wet, such as following intense rain. Problem Details: Initial Trigger: The problem begins when the vehicle is put into reverse after being exposed to water, particularly following heavy rainfall. Observed Malfunctions: The driver's side camera ceases to function immediately upon engaging reverse. Abrupt braking while in reverse leads to additional failures: The passenger side and forward-facing cameras also go black. Temporary Recovery: The cameras intermittently resume operation based on the vehicle's movement: Stepping on the brakes causes all cameras to go black. The cameras come back online one by one when the car rocks back, likely indicating water displacement around electrical connectors or modules. Hypothesis: The issues are likely caused by water affecting the electrical connections or modules associated with the camera system. This hypothesis is supported by the cameras' behavior correlating with changes in the vehicle's position and the presence of water. Recommendation: A thorough inspection of the camera system's connectors and modules is recommended, with particular attention to waterproofing and potential areas where water might collect and impact electrical components. Attached Evidence: The attached document contains pictures illustrating the camera issues as observed during the malfunction. These images were taken immediately after the intense rain when the vehicle was put into reverse and during the subsequent camera failures.

The brake system control module, engine control module, and vehicle stability control system have repeatedly failed across 24 months and 9 repair attempts at two authorized GMC dealerships in Tennessee. As of March 17, 2026 the vehicle has 27 active diagnostic fault codes including U160F and U1610 (brake system control module lost communication on both CAN buses), U1611 (engine control module lost communication), and C2A0A (vehicle stability control disabling inhibited). All components are available for inspection at Beaman GMC in Antioch, Tennessee where the vehicle currently remains in an undrivable condition. Safety risk: Vehicle has stalled on the highway with my family including young children in the car. Brakes have randomly engaged over 100 times with nothing around and also failed to engage when needed. Stability control is disabled. These are active safety failures confirmed by GMC's own diagnostic scans. The problems have been confirmed by both Darrell Waltrip GMC and Beaman GMC across 9 visits. GMC's own Technical Assistance Center (Case XXX) was involved and could not resolve the defects. The vehicle was returned with more active codes than at drop-off after 57 consecutive days in GMC custody. Two unresolved GMC safety recalls are open on this vehicle — L87 engine loss of propulsion (N252494003) and brake fluid leak detection failure — directly related to the reported defects. Warning codes have been present and documented since October 2023 beginning at 1,381 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle experienced a malfunction associated with a failed Over-The-Air (OTA) software update affecting electronic control modules. The (ECM), (BCM), and related electronic systems appeared to lose stability during operation. The vehicle attempted to reboot while being driven and displayed multiple system warnings. The vehicle is currently at the dealership and is available for inspection upon request. How was your safety or the safety of others put at risk?While driving, the vehicle began malfunctioning and attempting system reboots. The dashboard flickered, warning lights, and the vehicle exhibited unstable behavior. During a prior event, the vehicle experienced unintended acceleration and abrupt deceleration. This created a risk of loss of vehicle control, particularly in traffic. I have small children in this vehicle, and the unpredictable electronic behavior while in motion posed a significant safety concern. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealership confirmed that a previous event was caused by a failed OTA software update. The vehicle has since malfunctioned again while driving and has been taken back to the dealership for further inspection. The dealership has acknowledged module instability and opened a TAK case with the manufacturer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by GMC1 dealership. A case has been opened with GM Customer Care. No police or insurance reports. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? 9 days prior to the first major malfunction, the check engine light illuminate. On April 1, the check engine light re-appeared and the vehicle attempted to reboot again while driving.

My 2023 Yukon AT4 was taken to certified GMC dealer in November 2025 for the engine recall. The dealership gave my vehicle a clean bill of health at that time and the recall repair was cleared. On Friday, 2/13/26, myself and 5 other family members were en route to my godfather's veteran funeral service in Newtown, PA. We were going 75mph in the middle lane of the PA Turnpike when the motor seized up and vehicle lost all steering control and power. Since it was the side of the turnpike, we were limited in resources and stranded, missing the funeral service due to the length of time it took to get the vehicle loaded on a tow truck. Since the vehicle was unable to release the parking brake, the tow driver(s) were struggling to tow it. My husband, ended up having to go under the vehicle (on the side of the turnpike) to disengage the parking brake to help the tow drivers. This could have been a catastrophic situation. My vehicle was taken to a different GMC dealer than the original one that did the recall check. There are no rental vehicles available, so I am too out of a vehicle necessary for my work and family, with no time frame on the repair of my engine that only has 31,000 miles on it.

While driving approximately 63 mph on a busy roadway, my 2023 GMC Yukon experienced a sudden failure of the brake system, including loss of normal braking capability along with failures of the Electronic Stability Control (ESC) and ABS systems. The vehicle displayed warning messages stating “Brake System Failure” and “Service ESC” and entered a reduced-speed mode. Prior to this incident, there were no warning lights, messages, or symptoms indicating a problem. During the failure, the brakes became largely unresponsive, placing me, my two minor children who were passengers in the vehicle, and surrounding motorists at serious risk of a high-speed collision. After extended deceleration, a minimal amount of braking power partially returned, allowing the vehicle to eventually come to a stop. The vehicle has not yet been inspected by a dealer, manufacturer, police, or insurance representatives, and the issue has not yet been reproduced or confirmed by a service center. The vehicle remains available for inspection upon request and has not been repaired. This incident occurred without prior warning and involved a sudden and dangerous loss of braking capability at highway speed.

We are located in Henderson, NV and we were driving on the freeway in a construction zone with no emergency lanes when the vehicle lost all power to the engine going the speed limit. The engine had seized up which is a known problem with the 6.2L GMC motors. We have done all the recalls recommended by the manufacturer. The engine seizing, locking up , put our family in danger . We were luckily enough to be close to an offramp where people in other vehicles barley let us over so we can pull off the road or we would of been stuck in the middle of the highway with cars flying by us with little kids in the car. This is unacceptable and as much as this happening and GMC not fixing the issues, people are going to get hurt or killed. IT IS A HUGE SAFETY CONCERN! .

Vehicle lost steering and brakes suddenly. Many errors on screen such as: Brake System Failure, ABS Failure, ESC Failure, Traction Control Failure, Maximum Vehicle Speed 43mph. Was able to slowly get home with no power assisted brakes. Did not drive it any more until it was taken to dealer 2 days later and the dealer could not replicate the errors. Dealer was able to see stored error codes; however, they could not verify any errors in any of the modules or computer.

1 complaint

While driving in approximately 10°F weather after the vehicle had been parked outside overnight during snowfall in Chicago, the vehicle displayed a warning that said “Do Not Drive — Maximum Speed 43 MPH.” At the same time, the brake pedal became extremely hard and the vehicle had significantly reduced braking ability, requiring much longer stopping distance. This occurred without any brake warning lights beforehand. After the vehicle warmed up and was restarted, the message eventually cleared but then there was a new transmission warning and the check engine light went on. After driving for a long commute, eventually all warnings disappeared. I personally know another 2023 Yukon owner who experienced the exact same message and braking loss under similarly cold conditions, which suggests this may be a broader safety issue affecting this model year. Because this involved a sudden safety-system activation combined with temporary brake loss, there was a real risk of being unable to stop the vehicle safely or avoid a collision. My vehicle is within the year range of GM’s brake-system software recall N242447990 (eBCM brake fluid loss detection issue), and it is unclear whether my case is related, but the symptoms point to a potential systemic braking or electronic brake control problem in the 2023 Yukon. This issue warrants investigation due to the combination of: • Hard brake pedal • Reduced braking performance • Speed-limiting safety warning • No prior diagnostic warning • Occurrence in very cold temperatures A sudden loss of braking ability is a serious safety defect.

I bought my 2023 Yukon Denali Ultimate on or around August 9 2023, and I bought it brand new. On May 28 2024, around 30k miles, I was on the highway and could no longer accelerate. I luckily got myself into the breakdown lane before my car shut down & lost power, ended up being towed to the closest dealership. After 18 days at the dealership, I finally had my car back with a "new engine". Fast forward to November 25, 2025, I was on the highway again, my dash lit up telling me to "press start". As i figured that was not a good idea while driving in the fast lane on the highway, I did not. in a panic I got myself over to the breakdown lane where my car turned off. This time (November 2025), I still had power, but no car turnover. After 6 days of my car sitting at the dealership, they finally had the time to look at the issue. The Dealership did the recall and got the car started, but the car still had a funny sound that the mechanics didn’t like , so they were waiting to hear back from higher up people as to what to do. Today I got the call that they will be replacing the engine for a second time and I will not have my car back until the first week of January. There were zero warning lamps, Zero Symptoms, nothing. I am Lucky that the Highway wasn’t too busy in that moment, because there were many 18 wheelers on the road that day, and one almost swerved into my car missing it by about two feet while my dead car sat in the breakdown lane. Yes I called the state police, Yes one trooper kindly pulled behind me to ask if I was safe and had a tow on the way. But that truck that nearly plowed into my dead car could have prevented me from picking my [XXX] [XXX] [XXX] daughters up from school, forever . To say that I am disgusted with GM, is an understatement. They’re risking lives. I should not fear for my life, my kids lives in a new, "safe" vehicle. No pun intended, but this is highway robbery.

Nuna is not responding to customers questions or concerns adequately. They continue to just send you to their recall page. Complaints are as follows: - They also aren't honoring their warranty and replacing or repairing carseats still under warranty. - This recall is also causing damage to other components of the carseat (such as the strap - fraying, other use issues) that Nuna is not addressing. - It took Nuna over 4 months to send out the repair kit. After I contacted them, not vice versa. - The recall replacement seat cushions are extremely difficult to get on the seats, not color matched (the main reason this matters is because customers paid higher prices for various colors and they aren't being made whole financially). This is clearly not a universal fit for all year models. Even adult men are struggling to get these cushions on the chair by pulling them incredibly hard to fit. -Their carseats associated with the recall are failing at random, not in predictable replicable ways. I've had several instances where a child was strapped in and tightened only to find the straps completely loosened as the destination. The variables of child weight in the seat and movement are not being factored into the safety tests associated with this recall. You are testing an empty seat completely cinched down - not realistic to everyday conditions when in use. -Once you repair the carseat it's difficult to get everything lined up perfect to know the button is functioning exactly as designed. I now pull aggressively on the seat straps multiple times every time before I take off to make sure all is well. That doesn't feel like a safety win. -Customers are left with fixing the issue themselves (lots of time spent!). Nuna takes no accountability. Nuna's responses have been horrible. Customer service gets an F. As a repeat customer I am extremely disappointed. I have explored all avenues with Nuna and as a result am filing a NHTSA complaint.

While driving the 370 miles from Fairbanks to Anchorage with our family and dogs, our vehicle shut down completely with no warning. The drive is through a very remote section of Alaska. While passing a slower vehicle, our Yukon completely shut down, to include the all controls including the dash and lights. We were unable to complete the pass, leaving us in direct line with on coming traffic with no ability to speed up to get around the other vehicle. The other vehicle, not knowing we had lost all power, continued driving the same speed and eventually we were able to get back into the proper lane and coast to a stop on the side of the 2 lane highway. The vehicle would not start and with the temperatures outside at 12 degrees it got chilly fast. Luckily we travel with all of our winter gear. Had this incident happened on one of the many steep descents or curves with snow and ice, the outcome could have been disastrous. My wife has decided that if the vehicle does get fixed, she does not feel safe driving home in it. Reading online forums show that this is a very common occurrence and individuals are looking into a class action lawsuit against GM due to the safety issues associated with this. An individual passing by had a code reader and tried to reset the ECM but could not. I will include the report.

VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE

1 complaint

The vehicle was crawling to a stop in preparation to park in front of my garage door. When I move my hand across the steering wheel, my hand must have come in contact with the toggle/scroll for the “resume speed” function of the cruise control. The vehicle abruptly began accelerating towards my house. I was able to press the brake pedal to deactivate and stop the vehicle safely. I note that in the past week, perhaps even two, the cruise control has not been used. The vehicle is driven 2-4 trips a day.

Brand new vehicle, at about 5k miles the backup camera went out in April 2023. It is now December of 2023 and I have not had any sort of resolution. I have 3 children ages 2, 4 and 5 and it is very concerning for me and my wife to not have a backup camera especially at night.

On March 10, 2023 I exit Hwy 35 at the City of Cottula Texas, as I took the exit lane and arrived at the stop sign, the vehicle came to a complete stop the engine stop idling and the transmission switch to neutral, this created a safety issue for me and my family because I was unable to restart vehicle and I created traffic congestion at the intersection, I am worried that this can happen again and I might be exposed to other vehicles crashing against my vehicle or even worse if this is to happen in the highway I will not be able to control the proper handling of my vehicle
