ENGINE
On [XXX] I was driving about 75mph on the freeway and suddenly the vehicle gear switched from drive to neutral. The vehicle dashboard read "vehicle condition not safe for shift" I tried to put the car back in drive by pushing the drive button but the vehicle was stuck in neutral. I pressed on the gas but it was not working since the car was in neutral. Since I could not use the gas to move forward, I could not go up on the ramp and was stuck on the busy freeway between the off ramp and the busy lanes of cars going 70+. The right rear end of my vehicle was in the offramp lane. I started to panic because I had my [XXX] daughter in the car. The steering wheel was completely locked and the rear axel was locked as well. There was no warning before the engine cut off. The electrical was all still working. I called AAA for a tow and 911 for CHP assistance since I was in dangerous spot. Took it to GMC Carlsbad Service, advisor Jason just called me and told me the engine had seized up and will most likely need the engine replaced. On 1/9/25 I had the car oil changed at the GMC service department in Escondido where I purchased the car. The vehicle has an open ticket and GMC is conducting a full investigation. I am told the whole engine will need to be replaced and will take 4 weeks from 1/22/25 to fix. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, POWER TRAIN
My engine stopped while I was driving. Unable to accelerate and the car will not start and is dead. Transmission light and DEF service lights came on. Luckily I was able to pull over to safety, barely. It was towed to the GMC dealership and waiting for it to be looked at. There were NO warning lights that came on previous to when this happened. This is a HUGE SAFETY concern for GM and it needs to be a recall because many, many others have reported the same complaints.

ENGINE
The vehicle stopped, and I was unable to manually put it in Neutral. I had it towed to the dealership and was told that my engine was froze up. I have 25,000 miles on my Denali. This is not normal. My truck just "stopped" and would not move on a busy traffic road- why are the vehicles failing at less than 30,000 miles? I still owe quite a bit and now wondering what is going on with GM? I saw the video on Tik Tok about engine failures and this is my truck.

ENGINE
I purchased a 2023 Yukon Denali Ultimate new in December 2023. It has 25,000 miles on it. Last week my wife was driving on the interstate and the vehicle abruptly shut down leaving her stranded on a narrow shoulder on a bridge. After it was towed to the dealer, the diagnosis was a connecting rod failure requiring an engine replacement. It was in the shop 2 weeks prior because the vehicle shifted into neutral on its own while driving at 60 mph on the highway, but the dealer found nothing wrong

ENGINE
As we were driving down a main road and taking off from a stop light on NW Expressway we had no warning before the car seemed to die and shift itself to N. It said to press the start button, that did nothing and the car would not power back up besides the lights and dash that were still working. We coasted to a stop in a neighborhood entrance. I'm so thankful I was not on the highway during rush hour traffic. Once stopped, we put it in park and tried to start it. A friend came and tried to jump it and still nothing. The dealership has confirmed it needs a full engine replacement. GM has agreed to help with cost but my car has sat inoperable for over 30 days as the engine is on back order with no ETA. It has a 6.2L engine and I had taken it in for pull consumption tests over the past 2 years. The dealerships were unable to duplicate the problem. Two days prior to the failure I had told my husband it was slow to crank and we needed to have the battery checked. I now believe it was the engine, not the battery. There were no warning lights on and my battery indicter showed to be in the middle (not lacking charge). I am aware of a voluntary customer satisfaction program that GM has issued but they have told me my VIN isn't one of the 5000 affected by this. In visiting with the dealership it appears they will not fully break down my engine until the new one has arrived but they are 90% sure of the cause as they've "seen several of these". This could have been catastrophic to have a car die with warning in traffic.

UNKNOWN OR OTHER
During the operation of my 2023 GMC Yukon XL AT4 on [XXX], carbon monoxide (CO) entered the cabin, exposing my children and me to dangerously high levels of CO and causing confirmed carbon monoxide poisoning. We were driving with the engine running and the heater on for approximately 21 minutes when the exposure occurred. Symptoms began to escalate that day and into the proceeding days, including severe headache, stomachache, pallor, chest pressure, shortness of breath, fatigue, and neurological issues. My children, particularly my [XXX] and [XXX] , experienced the most severe effects— both were very ill especially my [XXX] . Unfortunately, we initially did not believe it was possible for CO to enter the vehicle cabin, which delayed early intervention and appropriate medical care. Blood testing 4 days later confirmed elevated carboxyhemoglobin levels in my [XXX] , the only one tested. During the incident, the battery warning light was the first indication of trouble, but soon after, many additional error messages began flashing on the dashboard. The vehicle then overheated, decelerated, and eventually shut down while driving. We were in the vehicle under 21 minutes. Upon inspection after the incident, my husband noted a severed belt and potential pulley issues. The exact cause of the CO intrusion has not yet been identified. The vehicle is available for inspection and unaltered to preserve evidence. I am writing GMC and requesting further investigation by GMC. This incident reflects a severe safety issue with potentially life-threatening implications for GMC owners. CO exposure can cause significant harm, and delayed identification in this case placed my family at substantial risk. Immediate investigation and corrective action are essential to prevent similar incidents from occurring in the future. Time is critical, as this defect could have catastrophic consequences for other unsuspecting drivers and their families.

ENGINE, UNKNOWN OR OTHER
Complete engine failure while operating the vehicle with our children riding along as passengers. The engine failure nearly caused us to wreck. 2023 GMC Yukon XL Denali with only 15,000 miles. And now, I am being told that I need a complete engine replacement and that GMC is well aware of these engine failures and the product defects, yet GMC has refused to issue a recall. To add insult to injury, I’m being told by dealership that it may take several months to get a new engine! We will be pursuing legal action.

Was able to safely steer the car to the side of the road to avoid a collision. Vehicle lost all electrical contact. could not shift into neutral to tow. Turns out vehicle engine had to be replaced. GM approved a new engine replacement and are planning to return the vehicle back to put on the road. The vehicle is unsafe, at 5k miles, 6 months prior, the vehicle had to have the steering system replaced due to failure as well. Online research shows that others are having the same issue with failed engines on these GM vehicles and models.

At approximately 9,000 miles the engine started knocking. I took it to the dealer today and they called to confirm the engine and radiator needed to be replaced as there are metal shavings in the oil. I'm not sure if it is the 6.2L engine lifter issue or if this is something different, nonetheless, engine issues for GMC seem to be systemic based on quick research and seeing posts in forums and social media.

ELECTRICAL SYSTEM, ENGINE
Engine shut off at freeway speeds (65mph) on 2 occasions. Driver was able to coast over to side of freeway both times. On 1st occasion CHP protected vehicle from other traffic on i-5 with safety lights and traffic control. On second occasion, tow truck came quickly and kids were evacuated to prevent heat stroke in 113 degree weather. The first incident was “repaired” with a new starter and battery fuse block at 21720mi, but only lasted to 21814mi before same event occurred. No warning of failure before or after incident, just a dead engine. Second event (7/2/2024) is still being investigated by dealership.

VISIBILITY/WIPER
Windshield wipers periodically fail to operate when turned on. This is but extremely dangerous because it's been impossible to determine what the cause is. When the wipers stop working, I adjust the speed from the intermittent settings to LO and HI and there is no change. I can turn the RainSense setting to OFF and there is no change. The wipers stop working and then after a few minutes, will turn back on. I have taken the vehicle to the multiple GMC dealers for service and they cannot diagnose the problem because it only occurs periodically. They refuse to change parts in an attempt to fix it. I have called GMC Customer Care and their response is "take it to another dealer". I have showed the videos I have captured of this dangerous situation and the dealers don't care. I have the videos and can share (but this site doesn't allow upload of videos). This is extremely dangerous. The wipers have cut out at highway speed in torrential downpour multiple times.

SERVICE BRAKES
Urgent Appeal for Investigation into Braking Capacity Discrepancy Dear National Highway Traffic Safety Administration (NHTSA),I am reaching out to bring a critical matter to your attention regarding the braking capacity of my diesel vehicle, which has not been adequately addressed despite multiple notifications to the service center.The primary concern I wish to highlight is the inadequate braking capacity of my diesel vehicle, which poses a significant safety risk. This concern is especially troubling when compared to my similar gas-fueled vehicle from the same manufacturer, which exhibits notably superior braking performance. After discussing this matter with the service center, their response was that the braking performance is considered normal for my diesel vehicle. However, the evident disparity in braking effectiveness between my diesel vehicle and the gas-fueled one suggests otherwise. This difference is particularly concerning given that both vehicles utilize the same brake system, despite the diesel vehicle's higher weight. In light of these circumstances, I urgently request NHTSA's intervention to investigate this matter promptly. The inadequate braking capacity of my diesel vehicle presents a tangible risk to road safety, affecting not only myself but potentially all drivers on the road.It is crucial that corrective measures are taken swiftly to address this issue and ensure the safety of all drivers. Your prompt attention to this matter is greatly appreciated.Thank you for your immediate action.
