ENGINE, POWER TRAIN
While traveling on the interstate at 10:30p, 6 hours into a highway trip, the vehicle shuttered violently and lost propulsion and powered systems control. We were traveling at 75 mph on cruise control and immediately had to take evasive action to avoid other vehicles traveling at highway speed as our vehicle rapidly decelerated to a stop. We were barely able to get to the shoulder of the highway before the vehicle came to a complete stop and all dashboard lights illuminated. There was no warning or indication of immanent failure or engine issue. The catastrophic engine failure did not allow for the attempted restart. After opening the engine bay we noted that the coolant reservoir was empty but there was no indication of any leaking fluid in the engine bay or on the ground. The coolant levels were normal at the trip start. We were stranded on the side of the busy interstate for approximately 2 hours awaiting OnStar assistance and were forced to exit the vehicle due to its proximity to the edge of an active lane, leaving us exposed and without any protection for 2 hours, in the middle of the night, until assistance arrived. It was a harrowing experience and we are lucky that we were not injured or killed. The vehicle could not be disengaged from park and had to be dragged onto the flatbed. It was taken to the local GMC dealership and left for diagnosis. It was determined that the #2 piston rod broke, smashed valves and sent metal into all engine systems. Bothe the engine and coolant system were replaced. In addition, the torque converter locked up and had to be removed during servicing. All parts were retained by GM.

POWER TRAIN, ENGINE
My vehicle started making a knocking sound and eventually died on me. I barely made it to a repair shop to check out my vehicle, but had to get it towed back to my home from the repair shop after they told me my engine failed. This happened around 118,000 mileage. I found out that this issue is very common and needs to be addressed for this year and model vehicle. It could have ended very badly for me as I was on the interstate when it happened. Now, my vehicle is sitting and I am unable to use it. Engine would cost me over $12k for cost and repairs.

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, FUEL/PROPULSION SYSTEM, POWER TRAIN
On 15 Aug 2025, I was driving this vehicle on Rte 151 in raccoon township with my 2 children when the vehicle suddenly and unexpectedly experienced a “loss of propulsion” with a corresponding uncommanded shift to “neutral”. Attempts to shift the car back into drive were met with a “parameters not safe” caution. I was fortunate enough that the vehicle behind me was able to slow and an accident was avoided. The thought that this could have happened with my family on the highway, during adverse conditions, or any other scenario is frightening to say the least. Other owners of affected models weren’t as fortunate.

POWER TRAIN
While my wife was driving to pickup my son from school, the vehicle was stopped at a stoplight and the engine turned off approximately 1 mile after departing the house. After getting the vehicle towed to the dealership because it wouldn’t start, it was determined by the dealership that the engine was seized. The vehicle has 60,500 miles on it and is driven by a suburban woman and has always had all maintenance done at the dealership. The vehicle is parked in our driveway and there are no signs of oil leaks or anything else that would indicate a potential engine failure. This VIN was not recalled with the larger GMC 6.2L engine failure recall, however other 2021 model years were recalled. Recommend immediate expansion of recall due to the unforeseen engine failure while driving with no previous warning lights (oil or check engine) or other indications prior to seizing. This experience indicates that the initial recall was not sufficient enough to locate and identify all of the 6.2L engines affected by the poor quality control issues at GMC.

EXTERIOR LIGHTING, LANE DEPARTURE: BLIND SPOT DETECTION, LANE DEPARTURE: WARNING
The LED left turn signal and blind spot detection ( safety feature) on the left outside rear view mirror suddenly stopped working. The is a TSB for warranty for 2016-2018 GM YUKON (#10-08-64-002D) and it states that the bulletin has been revised to include 2016-2018 year models for this defect. I am starting this claim because I am told by GM that my VIN is not covered under this warranty, yet I am experiencing the same issue stated in the TSB listed above.

POWER TRAIN
Dealership did a tune-up in June 2025 and had my truck for 2 weeks, no issues with transmission discovered or discussed. Now in September 2025, 2018 GMC Yukon has developed a torque converter shutter when driving between 40 and 50 mph. I took the vehicle to an independent shop who told me they had some computer tool to manually control the transmission, and there is an internal failure. There was a transmission flush completed hoping to gain results, however it was very short lived.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
After less than 2000 miles, the OnStar module failed, which removed the capability for emergency assistance, GPS, advanced cruise control, etc. The part is on back order with no ETA, and it appears, based on my research, that this is a common problem with GM vehicles for the past several years. Not having the emergency assistance phone system available is an extreme safety issue, as there are many areas of the US that do not have adequate cell coverage to get assistance in an emergency. It seems as though GMC does not care.

ENGINE
Valve spring snapped clear in half inside the engine while driving on the highway. This caused me to be stranded on the side of the road in the middle of the Arizona desert with my two dogs in the heat. Thankfully I did not lose control of the vehicle. No warning signs whatsoever until out of nowhere- vehicle check engine light started flashing as well as 'service stabiltrak' and 'traction control disabled'. I immediately pulled over. Thankfully I shut off the engine in time to prevent further damage to the pistons. Vehicle was towed and inspected by Holden's Auto Service in Kingman, AZ. Valve spring broke clean in half and was given to me after valve spring was replaced. Compression tests were performed after valve spring replacement. engine was run until warm and normal compression resumed. No other mechanical issues found. Checked for recalls on this vehicle. nothing found related to this.

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.

The 6.2 engine in our 2025 Yukon Denali with 3,200 miles just locked up. It needs to be replaced. They said they fixed the problem and it was only affecting 2021 to 2024, but it is carrying over into 2025. They should just buy this vehicle back.

I was driving on I75 North, just North of Chattanooga. I was in the Center Lane. I lost all power to the vehicle. The engine stopped. I had no power steering, no power brakes, and was in heavy traffic. I managed to shift lanes and get it to the shoulder of the road. The vehicle was towed in. Diaganostics were completed by a certified mechanic. The engine had seized. GM has several recalls on this issue. 2018 is not included. However, this is the exact same issue that is happening with 2019 and up. That were recalled. I urge you to order an extended recall to include 2018 vehicles as well before someone gets killed.
