ENGINE
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.

SERVICE BRAKES, STEERING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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"

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, VEHICLE SPEED CONTROL
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.

ENGINE
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

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.

ENGINE, VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
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.

GM has failed to resolve repeated issues on my vehicle (VIN: [XXX] ). I was never notified of any official buyback denial. GM Customer Assistance continues to avoid clarifying the status and refuses to provide documentation of the denial. This creates an unresolved safety and reliability concern. I need an investigation into the consistent mechanical defects paired with GM’s refusal to properly process my claim.

SERVICE BRAKES
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.

ENGINE
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.

SEATS
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.

ENGINE
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.

VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
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. This vehicle has not been confirmed or inspected at this time.

ENGINE
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.

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. There were no warning signs prior to this incident.

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? They are being irresponsible with their approach to this issue.
