1. The authorized dealer repair center stated my engine has failed and needs to be replaced. It is currently at the dealer so it's unknown if it is available for inspection. I'm sure if the inspector would go to the dealer I can make that process happen. 2. The point of complete engine failure has not occurred as of yet to me so It is unknown how this would effect my safety. One would have to assume that engine failure could always be a safety problem if driving when it occurred. 3. The problem I reported has been confirmed by the authorized dealer. 4. The vehicle has been inspected by the authorized dealer repair center but I am not aware of any other people that performed same inspection. 5. There was a knocking noise come from the engine when I accelerated and loss of power when accelerating. The noise was first detected 12/24/24 and I made an appointment with the authorized dealer repair center online. My vehicle was dropped off the first available day on 12/26/24. I have time & date video of the engine issue if wanted.

ENGINE
While passing on a two-lane road at approximately 70 MPH, the vehicle stalled and acted as if the engine wasn't running. Pulled over to the side of the road and was able to restart the engine after shifting to park. Engine was harder to start than usual and cranked slowly. After restarting, the engine ran fine for the remainder of the trip, but would occasionally have difficulty cranking. After this incident, the engine developed a knock that would vary with engine RPM, and sounded like a defective connecting rod bearing. Pulled the dipstick and noticed metal shavings in the oil. Took the vehicle to local dealership who confirmed the engine was defective and would require replacement. Vehicle has been at the dealership since December 5th waiting for a backordered engine.

I’ve had the engine blown and replaced twice. The first time it failed in the middle of an intersection. We could not put it in neutral to move it. We had to call a tow truck. No check engine lights just a noise. The engine had failed bc the bearings couldn’t get oil. The second time it blew I was driving down the interstate and same thing only a noise so I pulled over and the car died. Also had to call a tow truck. It was the same as the first time the engine had blew because of the bearings not getting any oil. So now I’m on my third engine in a 2023, hoping that it doesn’t do it again.

ENGINE
I have a 2022 Yukon Denali. On [XXX] the engine failed with approximately 33,000 miles on it. When the engine failed, we were traveling on a highway in New York State at a high rate of speed. Everything shut down but the steering and brakes. This put us in a dangerous situation in which we had to exit the freeway and call for a tow truck. It was still under warranty. They replaced the engine and completed the project on November 5, 2024. They delivered the car from the dealership that repaired it in New Jersey to my home in California on December 9, 2024. The new engine they installed failed on December 10, 2024. I brought it to Winter Chevrolet in Pittsburgh California. As of January 18, 2025 they have still not been able to locate a new engine to install. As of today, it has been 117 days since I’ve been without the use of my car. In my dealings with General motors, it appears that their goal is just to stall until they find an engine to install in my car also we have had no clear explanation or diagnosis of what actually is wrong with the car.

ENGINE
In July of 2024 while coming back from vacation pulling our boat our 2021 Yukon Denali with 6.2L motor started making noise while traveling on the interstate. I started to get over to the shoulder as the car lost power. I finally got it over to the shoulder as traffic was heavy and it was pouring down rain. As soon as I got it to the side of the road the check engine light came on and the engine died. It would not turn over or restart. After about 3 hours along side the very busy highway in bad weather GM finally sent a tow truck to take it to the dealer. After a week in a half it was finally diagnosed with spun rod bearings and main crankshaft bearings. The car had just over 21,000 miles and had been serviced per the manufactures recommendations. It took over 7 weeks for the car to be repaired where they replaced the engine with a remanufactured engine. We did not get a loaner car since it happened in KY and we live in IN. Our family had to find our own way home and a way to get our boat home also. We then had to find our own way back to get the vehicle once it was repaired. GM did reimburse us for a rental car at $44 a day only and they did not pay any taxes or fees only the rental rate. You cannot rent a similar sized vehicle for $44 dollars a day. We spent approx. $2K out of our own pocket for expenses related to this breakdown. The vehicle now has approx. 29,000 miles on it and we have not had any problems since we got it back

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.

Without any warning while driving on the interstate the vehicle became disabled and released smoke. After being towed to dealership for diagnostics we were informed of engine failure. No warning on that day at time of the very dangerous event or prior warning of any engine related issue. All maintenance and service records are on file with GMC dealership. We requested our service advisor with Ewing Buick GMC to contact GM regarding this matter. We were told they reached out but that GM offered no assistance. After some research it does appear there are several issue reported concerning no warning engine failure with the GMC Yukon. This was a significant safety risk since the vehicle displayed no warning signs of any engine problem. It goes without saying the financial impact related to the very unexpected engine failure in a 2018 vehicle. Thanks in advance for your review and consideration regarding this safety matter.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
My brakes are not working properly. I can be backing up and put my foot on the brake. My truck will keep moving until I apply a lot of pressure on the brake pedal. I can be backing up and my truck will automatically brake and stop moving. I have to cut the truck off, start it back up for it to move. I was in a stand still traffic jam and braking a lot and my truck did stop it keep rolling. Sometimes when I apply the brake it slides.. This is the third time I have put it in the shop. I changed the brakes, brake sensor and replaced tires. I am scared to drive it. My truck is currently in the shop now for the brakes. please help.

SEAT BELTS, SEATS
The third row seat attachment from the seat to the frame has broken. It is a hook type mechanism that holds the entire row of seats to the latch in the floorboard. This car was not in an accident and the seats broke when the vehicle stopped. There should be a recall. Also the back seatbelt was on a recall for this vehicle but doesn't show up anymore. Please restore the recall. Thank you

ELECTRICAL SYSTEM
We received an alert/warning that is nearly constantly beeping and servicing the trailer brake system. We have never used the wiring or towed anything, and the trailer brake system is unused. The beeping is near constant, even after we “dismiss” the alert and is very distracting when driving.

ELECTRICAL SYSTEM
I have been told the MODULE ASM-COMN INTERFAC Part #86581706 has failed and is on back order, with no anticipated in stock date, and not available to be repaired. This controls the vehicles communication with Onstar which is currently not working. Onstar is sold as a safety feature of the vehicle. In addition I do not have access to the location services of the vehicle, also sold as a safety feature of the vehicle. The vehicle is available to inspection. The problem has been inspected by a GMC Dealer. There were no warning lamps, messages or promts when the module failed. I had to have the failure diagnosed by the dealer to locate the failure.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
My vehicle radiator fan immediately cut on high when I turned on the vehicle. The temperature of the vehicle was normal. I also experienced this when the engine was completely cold. I was assured there was no need to tow the vehicle but I could drive and schedule service with dealer. The software triggered a reduced acceleration condition. This did not allow me to accelerate as needed while navigating an interstate interchange.

UNKNOWN OR OTHER
I am submitting this complaint regarding a persistent and significant transmission issue with my 2017 GMC Yukon Denali, which I purchased in June 2024. The transmission has been malfunctioning, causing the vehicle to jerk and hesitate, particularly during acceleration. This component is available for inspection upon request. Safety Concerns: This issue poses a serious risk to my safety and the safety of others on the road. The jerking and hesitation during operation can result in delayed acceleration or unexpected speed changes. These problems have occurred while merging into traffic and driving on highways, creating hazardous situations where immediate and reliable vehicle performance is critical. Reproduction and Inspection: The problem has been reproduced and confirmed by an independent mechanic who inspected the vehicle. The diagnosis identified a transmission malfunction, which appears consistent with reports from other owners of GMC Yukon models. However, the vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. Warning Symptoms: There were no warning lamps or error messages displayed prior to the onset of the issue. The jerking and hesitation began soon after I purchased the vehicle in June 2024 and have progressively worsened over time. I have discovered that GMC has issued recalls for similar transmission issues in later Yukon models (2021 and 2022). However, despite widespread complaints, earlier models like my 2017 Yukon Denali have not been included in these recalls. Given the safety risks associated with this transmission defect and the frequency of similar complaints from other owners, I urge the NHTSA to investigate this matter. Prompt action is essential to ensure the safety of drivers and passengers in affected vehicles and to hold the manufacturer accountable for addressing this defect.

ENGINE
I was driving on the highway at about 70 miles an hour and my vehicle started to decelerate without warning, dash lights came on. I was able to safely get off to the side of the road. The vehicle would not start, so I had to call a tow truck. Once towed to the GMC dealership and looked at by mechanics, I was told the engine failed and I would need to replace it. I was also told there were metal shavings in the oil. My vehicle did this without any warnings. I never had the check engine light come on before this incident, nor were there any noises that would make me think something was wrong with my vehicle.
