  My vehicle was apart of the GM L87 recall. I took it to the dealership and it passed the recall and received the remedy which was an oil change. Now about 3 months later, I was driving in the highway at approximately 70 mph when the vehicle lost power and shifted to neutral. I had to attempt to veer off the highway with no acceleration. Upon getting it to the side of the highway, it wouldn’t do anything at all and had to be towed. The dealership has deemed it needs a new engine due to the failure the L87s are facing. We had no warning at all prior to the engine failure, and assumed that after passing a recall it had some degree of safety.

  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.

  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.

  In April 2022, I purchased a brand-new 2022 Yukon Denali from Roberts-Robinson Chevrolet GMC in Excelsior Springs, MO. Shortly thereafter, the first engine failure occurred in October 2022. The vehicle was towed to GMC AutoNation in Golden, CO, where it remained until repairs were completed in January 2023. Soon after the vehicle was returned, the second engine failure occurred in February 2023. The vehicle was again towed to GMC AutoNation, and repairs were not completed until April 2023. At that time, given the repeated failures, I worked with GMC and Roberts-Robinson Chevrolet GMC to replace the vehicle entirely. I took delivery of a new 2023 GMC Yukon Denali as a resolution. On October 8, 2025, the engine on the 2023 Yukon Denali also failed, marking the third major engine failure I have experienced across these vehicles. The vehicle was towed again to GMC AutoNation in Golden, CO, where it remained for two months. I picked up the "repaired" vehicle on Tuesday, December 9, 2025. This pattern of failures has caused significant disruption and distress. I have spent countless hours coordinating tows, securing rental vehicles, and seeking reimbursement for out-of-pocket expenses. More importantly, these repeated engine failures, all of which occurred while I was driving 65 MPH on I-70 through the Colorado mountains, have created extremely dangerous situations for me and my loved ones. Navigating heavy traffic during sudden engine failure and waiting on the roadside for assistance has been frightening and unacceptable for a vehicle of this caliber. Overall, this experience has been incredibly stressful and disappointing.

  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. Dealer wants us to take it back and wife is scared to drive it due to no fixes or repairs. Loss of brakes and steering is NOT a situation to ask an owner to 'bring back when it happens again"

• 12/10/2025· VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

  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 brought my 2023 Yukon in for the 6.2 GM inspection, and was told my engine was good, and the engine oil was changed. Approximately 3 weeks later the engine in the Yukon failed (seized) while I was towing my boat at 55mph, nearly causing an accident. I was able to pull the vehicle and boat to the side of the highway in a precarious location, which put me, my family and property in danger. There were no warning signs or messages on the dash, and no engine sounds. I believe GM's recall inspection and "preventative" oil change did nothing, and gave me a false sense that the truck was safe to tow with. I want to make sure the NHTSA is aware that the engine failed even after being screened with the recall. THIS FALSE REASURRANCE THAT THE TRUCK IS SAFE IS PUTTING THE PUBLIC AT RISK

  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.

• 11/15/2023· SEATS

  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.

  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.

  The vehicle engine experienced a failure on the highway at very high speeds with no warnings leading up to this occurrence, same as many of the experiences of the customers with the 6.2L engines, which have been recalled for these defects. This GMC Yukon has the 5.3L engine, however, has the same defects as the 6.2L engine, excessive oil consumption and eventually engine failure. I am without a vehicle, with an extremely high car loan, and have to replace an engine in a two year old $75,000 vehicle. This should be covered by GM as it was a known issue and continues to be sold to unknowing customers. Furthermore, I am paying even more money to put another engine in this vehicle with the potential of having the same issues as the problem has not been corrected. This is deceptive and theft by GM in my opinion, and not safe to have engines failing in the highway with no warnings at all.

  I was driving down 85 South bound at mile marker 16 the engine started messing up causing me and my family to be pushed over to the median. Once I was able to fight it over to the median it started smoking and i was afraid it was going to catch fire, so me and my family had to get out on the side of the interstate until help showed up and said it was safe to get back into the car. I had to use OnStar to get a tow truck, after the tow truck got there and i made it to the closest dealership to find out that the so called recall that the GM dealership fixed did not help the fact that the engine was messed up. So i tried to get a loaner or rental car for my family of 6 and they rented me a small SUV that I can not get all my kids into, I was told they did not have anything that bigger so now I am having to make multiple trips getting my kids to school. Plus they are saying it is going to be months before I can get my car back because the engine is on back order.

  Purchased 2023 GMC Yukon on August 21, 2025 and after starting the vehicle on October 2, 2025 the whole instrument panel cluster malfunctioned, failed to turn on, currently does not work and is available for inspection upon request. The instrument panel cluster is all black, it shows glitching flashing white lines on the right side of it therefore being unable to read the speedometer, fuel gauges, tire pressure, oil life, engine temperature, etc.. Prior to the instrument panel cluster malfunction, there were no warning indicators. Being unable to view the instrument cluster, makes the vehicle hazardous & risky to utilize for me and my family.

  my 2023 GMC Yukon Denali (VIN: [XXX] ), which is included in Safety Recall N252494003 for a known defect affecting the L87 6.2L V8 engine. My vehicle was first inspected under warranty in December 2024 at Serra Traverse City Buick GMC due to a burning smell. I was informed at that time that no issues were found. I was later told by the former service manager that the technician who evaluated my vehicle during that visit was let go due to poor workmanship and lack of product knowledge. Since that time, on two separate oil changes — January 8, 2025 and May 9, 2025 — my engine was found completely out of oil, with no oil on the dipstick. The documentation had to be retroactively added after my request. This pattern raises serious concerns about oil consumption or internal engine damage consistent with the recall defect. The dealership declined to replace the engine or perform any further diagnostics beyond the standard recall inspection. I was advised to retrieve the vehicle. However, I remain deeply concerned about the long-term safety and reliability of this vehicle, especially given GM’s acknowledgment that this defect may lead to engine failure and loss of propulsion. I have made multiple efforts to escalate this issue through both the dealership and GM’s customer service line. I was advised by Service Advisor [XXX] to contact the GM representative for regional review. He directed me to file a bbb claim.. Both GM and bbb denied my claim, stating out of warranty. However, the dealer explained that my issue were documented under warranty and would be handled appropriately if the issue persisted. GM contacted me an offered a $4000 credit. Unfortunately the problem still persist. I’m 3000 miles from being due for an oil change and again have no oil on my dipstick.

  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.

  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.

  After stopping at a stop sign, I accelerated for a few seconds, but then it shifted to Neutral and the screen said "Press Start Again". I pressed Start, accelerated for a few seconds, and again it shifted to Neutral and the screen said "Press Start Again." I repeated this process a few times and luckily made it to the end of our driveway. I could no longer move the car nor could I shift gears. When trying to shift gears, the screen said "Conditions Not Correct for Shift." I requested Roadside Assistance. There is no way to get this car into neutral so he had to manually pull it onto the tow truck bed. The nearest dealership diagnosed it as engine failure and replaced the engine.

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.

  Recall issued in April states that the Engine could experience a catastrophic failure and needs to be inspected for possible replacement. At this time (8-30-25) they are not allowing the dealers to perform these inspections. Why can't they at least perform the inspection to see if in fact the Engine will not need to be replaced?

  My 2023 GMC Yukon has had a strong mildew/musty odor coming from the HVAC system since the vehicle was new. The odor is most noticeable every time the vehicle is started after it has been sitting for several hours or overnight. After the system runs for a short time, the odor dissipates. This concern has been reported to my GMC dealer on multiple occasions. Previous repair attempts have not permanently corrected the problem, and the odor continues to worsen. The smell is now strong enough that it is embarrassing to have passengers in the vehicle. I have followed the recommended preventive measures, including replacing the cabin air filter, turning the A/C compressor off several minutes before shutting the vehicle off, and attempting to clean the HVAC system with commercially available products. None of these measures have resolved the issue. Based on discussions with other GMC Yukon owners, this appears to be a common and recurring problem affecting numerous vehicles of similar model years. Many owners report the same symptoms and repeated unsuccessful repair attempts. This suggests the issue may be related to the design or operation of the HVAC system, particularly moisture remaining on the evaporator core, rather than normal maintenance. I am requesting that GMC investigate this recurring defect and provide a permanent repair rather than temporary odor treatments. Owners should not have to repeatedly clean or service the HVAC system to address a condition that has existed since the vehicle was new.

  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.

  On June 25, 2026 my 2023 GMC Yukon Denali with 53,456 miles was brought to an authorized GMC dealership after displaying a Service 4WD warning light and exhibiting a groaning noise when shifting into Drive and Reverse. The vehicle was diagnosed with the following brake system fault codes: P25A2, C0511, C0517, C1595 and C1596. These codes indicate brake control module failure and wheel speed sensor faults which are safety critical components. The dealership confirmed these findings but stated the repairs are not covered under the GMC powertrain warranty. Given that these are safety critical brake system failures on a nearly new vehicle with only 53,456 miles, we contacted GMC Customer Care on July 1, 2026 to request coverage under goodwill warranty as we believe these failures constitute a manufacturing defect. A case was opened however after 7 days no case advisor has been assigned and no decision has been made despite two promised timelines not being met. The brake system failures on a nearly new vehicle represent a serious safety concern as these systems directly affect the vehicle's ability to stop safely. The vehicle has been at the dealership since June 25, 2026 and remains unrepaired.

  After driving on an Interstate Highway for approximately 2 hours I exited and brought the vehicle to a complete stop at a stop sign while preparing to turn right onto a busy 2-lane road. I applied moderate gas pedal pressure and the vehicle momentarily accelerated and moved forward but then the engine stalled as the transmission was attempting to shift automatically from 1st to 2nd gear. The vehicle was partially stuck out into the busy road without any power. This created a traffic conflict and near-miss with cars traveling along the 2-lane road that I was attempting to turn onto. I restarted the vehicle and drove it slowly onto the shoulder. The vehicle’s engine repeatedly stalled any time enough gas pedal pressure was applied to cause the transmission to attempt to shift from 1st to 2nd gear. This issue only occurs after the engine and transmission have been running at operating temperature for several minutes. The dealership could not duplicate this issue, but they only drove the vehicle a total of 7 miles over two different occasions. The vehicle was purchased new on June 23, 2023 and had approximately 1,700 miles on it when the issue first occurred. There were no warning lights or messages illuminated prior to the engine stalling. Vehicle is currently at a dealership service department being evaluated.

  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 contact owns a 2023 GMC Yukon. While the contact's wife was driving approximately 5-10 MPH on a city street and approaching a stop sign, the vehicle experienced a failure and became inoperable. The contact stated that while the driver was attempting to restart the vehicle, the battery warning light and engine warning light illuminated, and the "Low Battery - Start Engine" message was displayed. The vehicle was towed directly to a dealer to be diagnosed. The dealer was unable to determine the cause of the failure but provided an estimate for the valve springs inspection. The vehicle was not repaired. The manufacturer was notified of the failure and was working with the dealer to determine how to repair the vehicle. The failure mileage was approximately 71,481.

  The panoramic sunroof has a substantial leak, even though the 2023 vehicle only has 33,000 miles on it. The drain lines are clear but water continues to significantly leak out of the rear passenger seatbelt housing onto the seatbelt. There is also significant water drainage through the rear interior lights onto the upper legs of rear passengers (children in car seats), causing a severe electrical hazard. The leaking caused by the drainage defect affects the interior lighting, the seatbelts, and is a potential electric hazard. This seems to be a common occurrence and the manufacturer should repair their defective products. The drainage pipes are obviously either not assembled correctly or the materials don’t hold up. This should not be occurring in a $55,000 vehicle with 30,000 miles. I have multiple videos I can provide but the file sizes are too large to upload, so I took screenshots. I am going to pay for the repair but I should be reimbursed by GMC.

  My car started making a knocking noise under the hood 2 days prior to it breaking down (6/19 & 6/20). On 6/21/26, I was driving down the interstate WITH my kids in the car and it shut down on its own. Lights came on my dash and the vehicle quickly slowed itself down and when I pulled over to a complete stop, the vehicle shifted into neutral and shut off. I was not able to crank it back up and had to pay a tow company $243 out of pocket to tow it to our local dealership in town. My insurance only covers $200 for towing. I am a week without a vehicle and just found out Friday (6/26) that a new motor will have to be ordered but it is on back order with no idea on when it may arrive. I cannot get an answer from GM or my local dealership on if a rental will be provided. I cannot make 2 car payments but I also have a job and cannot proceed without having a vehicle to drive. This has put me in a bind for a week already with no solution in sight. I expect GM to fix my problem asap since it is theirs to fix!!

  The vehicle is equipped with “rain-sensing windshield wipers” but they do not work due to poor design. They should not have failed this quickly (33,000 or so miles). The windshield wipers must be manually activated because of this defect, but since the manufacturer thought they would be automatic, they made the manual activation very hard to access. It is very dangerous trying to activate them while operating the vehicle because A) your eyes are off the road for an extended period in poor conditions and B) the control is in a hard-to-reach area. You have to turn the nob 6-7 positions to put the wipers on low or high, and for the first 5 positions the windshield wipers don’t activate.

  There's a recall on my SUV ... recall ID 25V274. The dealer told me that there is no part available currently so they refuse to inspect my SUV. I believe if the inspection revealed that there is no defect relating to the recall, the dealer is required to use higher viscosity oil. I've asked them to perform this inspection while they wait for the parts, but they refuse to do so. As summer vacation is here, what if the defect in fact does exist in my SUV that will cause a dead engine while driving on the highway, and we get hit by a semitruck killing me and my family. That would be too late isn't it!? How long must I wait for the parts and continue to put my me and my family's safety at risk?
