ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
The engine of my 2024 GMC Yukon Denali failed unexpectedly at 45 MPH, shutting off without warning and shifting into neutral. My wife, three passengers, and two dogs were in the vehicle, which coasted to a stop. After several attempts, it restarted, and the check engine light illuminated. Alpine Buick GMC confirmed catastrophic engine failure, requiring replacement of the engine, radiator, hoses, and other parts. The vehicle remains at the dealership, and the failed components are available for inspection. This sudden shutdown posed serious safety concerns. My wife lost control over acceleration and power steering, increasing the risk of an accident. Had this occurred on a highway or in traffic, the consequences could have been severe. This raises concerns about the engine’s reliability and potential risks to other drivers. Alpine Buick GMC confirmed the engine failure and the need for full replacement. I am the sixth customer awaiting this repair, indicating a broader issue. The estimated wait time for an engine is two weeks to three months, creating a significant disruption. Inspection by Manufacturer, Police, or Insurance The vehicle has been inspected by dealership technicians but not by GMC representatives, police, or insurance adjusters. I am open to further inspections to determine the cause and assess whether a recall or corrective action is necessary. No warning lights or symptoms appeared before the engine shut down. The check engine light illuminated only after restarting on the third attempt. The absence of prior alerts suggests a flaw in the vehicle’s diagnostic system. Expedited Engine Replacement – Given the safety risks, I request priority replacement. Investigation into Failure Cause – GMC should assess whether this is a manufacturing defect. Review of Similar Cases – If widespread, a recall or service bulletin may be necessary. Better Communication – Regular updates on repairs and GMC’s actions are needed. I expect prompt action to resolve

ENGINE
We were driving from another part of town back to our home on a very busy road, when our 2024 Yukon Denali Ultimate stopped working. My wife, who was driving, was able to turn onto a side road and stop the vehicle on the side of the road. The SUV would not start at that point. It was towed via a flatbed trailer to Ray Miller GMC, where it was determined that the engine had seized. I bought it at Howard Bentley GMC. They had it brought to them. GM only is offering an extended warranty even though the engine is being replaced, and the vehicle has inherently lost value. Luckily, Howard Bentley is giving me my money back towards a new 2025 Yukon AT4 Uktimate.

ENGINE, ELECTRICAL SYSTEM
What component or system failed or malfunctioned, and is it available for inspection upon request? The engine suffered a catastrophic failure, including a bottom-end bearing failure, causing the camshaft to seize, the flywheel to shear off, and metal to spread throughout the engine, cooling system, and radiator. This also tripped the main fuse, resulting in an electrical short. The failed engine is currently at the dealership and is available for inspection upon request. How was your safety or the safety of others put at risk? I was driving on a 55 mph highway when the engine completely shut off without warning. Losing all power while traveling at highway speeds was extremely dangerous, and I was barely able to glide the vehicle to the side of the road before it lost momentum. It is terrifying to think of what could have happened had I not been able to get out of the travel lane in time, especially with other vehicles moving at high speeds around me. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealership diagnosed the issue and confirmed the engine failure. They have determined that a full engine replacement is necessary. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by an authorized GMC dealership service center. I have not yet had it inspected by any other parties. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights or messages appeared before the engine shut off. The failure was completely sudden and unexpected, with no prior symptoms or indications of an issue.

ENGINE, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
aside from constant electrical issues with the serial gateway module that gm refuses to replace many safety features fail regularly most importantly this replacement yukon for the 2023 with engine issues also has engine issues and the same 6.2L engine. When leaving my home and or driving on any decent up or downhill road and coasting the vehicle will misfire and trigger the MIL to flash. I’ve taken it into the dealer many times for this and in the end they say it’s a software problem with AFM disabling 5 cylinders. They claim that the geometry of the vehicle along with having 5 cylinders disabled causes the engine to vibrate enough to make it think it’s misfiring. this came from their factory field service tech. they refuse to fix it. they refuse to put this on paper. they told me if I wanted it fixed, I could buy a 2025 instead. this is insanity.

ENGINE
On [XXX], I was driving approximately 70 MPH on [XXX] when the engine stopped without warning. I had the vehicle towed to Causley GMC where it was repaired. I was on the way home from Causley driving on [XXX] when the engine stopped again. I had it towed back to Causley. The next day they called me and said that the engine was destroyed and needed to be replaced. Both times it stalled I was on the expressway and if I were not able to coast to the side of the road, I would have been in a very dangerous position for me and everyone else on the highway. There was not a warning before the engine stopped, so it was very fortunate for me that I had enough momentum to be able to coast far enough to get in a safe position.

2024 Yukon AT4 14,214 miles. I heard a metal dropping sound that morning but otherwise it acted fine. I thought something fell in the vehicle but nothing was there. No lights came on. Then later that day it just died at a light in town. Suddenly received low oil pressure warning and vehicle shutting off. Happened out of no where. Was able to start it and get off out of middle of road. It continued to die over and over and then finally wouldn’t start again. Towed to dealership. Dealership able to start it once there but stated check engine light was on. We called for an update after a week of waiting and were told that it needs a new engine.

Was driving on the interstate when the engine stopped running. My screens went off and came on saying to press the start button to turn on as my car is still moving. Once pulled over couldn’t get the car to turn off or shift out of park. Engine never started since then. Mechanics looking at the Yukon have verified that my engine did seize up. My car is less than a year old.

ENGINE
Was driving on highway when the engine started to labor. Without notice the car flipped into neutral. Obviously this was very dangerous going from acceleration to no engine power. I barely made it to the side of the highway by crossing two lanes to get there. When on the side of the road the car went into park and was unable to move to any other modes. Not even neutral. Again very lucky to have gotten off on the shoulder. Once the car came to a stop we were stuck for good. Had to get towed 60 miles or the nearest dealership with my wife and two young children. Took the car to a GMC dealership who said; “yeah this has been happening with the V8s”. It has now been 30 days and still no updates from GM outside of them waiting on a new engine. Also GM only gives you $44/day for a rental car which doesn’t even come close to covering a like kind vehicle. We had a 2024 Yukon Denali. I am now without a car and the only communication I am getting from GM and the GMC dealership is to wait until they receive and replace the engine, which they say should hopefully fix the problem. I am not taking the risk that this could happen again with my family in the car. Looking to get some form of a buyout and move into a different car.

On November 13, 2024 I was operating my vehicle at approximately 55 miles per hour when it suddenly experienced complete engine failure. The incident occured at 10 o'clock at night, and the loss of power resulted in the immediate shutdown of all vehicle systems, including headlights. Due to the unexpected nature of the failure, I was unable to bring the vehicle to an immediate stop. Fortunately, my three children and I escaped the incident without injury. The vehicle eventually came to a stop, and I was able to assess the situation and contact OnStar. The vehicle was towed to dealership.

Driving on highway and engine cut off with no warning. No dash lights to show a warning. 3321 miles on engine. The vehicle was unable to be put in neutral for the police to push it out of the highway. Three Moncks Corner police cars surrounded the vehicle to maintain safety. The vehicle was towed to the dealership. Needed a new engine and cooling system. The engine and cooling system were both replaced.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
1 Adaptive cruise stopped me several times for no reason as there was nothing on the interstate and the weather was clear. This was very jarring at 80 miles per hour on the interstate created a hazardous and dangerous driving condition as cars were all around, almost was rear-ended. 1a Adaptive cruise started all the sudden when I was stopped at an intersection almost caused a wreck, as soon as I took my foot off the break it speed up, but I was able to veer off and break several more times. The adaptive cruise should automatically go off when the brakes are applied. 1b Cruise control will not activate sometimes (it is intermittent). 2 Sensors do not work properly and do not go off to warn if I have driven to close to something, this has happened several times after I became aware of it and after front bumper was damaged. 2 Garage door opener works sometimes, this means I have to get out unlock the house go shut the garage door and relock the house... very unsettling. 3 Android Auto goes out continuously and will not reconnect even though the maps are still on my phone and everything is setup correctly. This also creates a hazardous condition when driving on the highway in unfamiliar areas causing me to miss turns and unable to navigate through traffic. 4 Seat, adjustable setting does not work when entering the vehicle, only upon exit. 5 Mirrors do not automatically fold when parking the vehicle as they did when I purchased the GMC. 6 Rearview camera doesn't turn off automatically after reverse parking has to be done manually while driving. There are so many issues with this vehicle. I have serious concerns with the safety of this Yukon. I have filed a lemon law with GM on the Yukon. The GM representative Lied in the abrtration stating there was a recall that would fix these issues....The dealer was notified within a week of the purchase but had me wait until GM had a software fix.... They stated the software update should take care of all the issue
