On May 6, 2026 while driving on the interstate, the vehicle automatically shifted into Neutral, and lost all engine power. The vehicle would not shift back into drive or even 4x4 neutral to be towed. The vehicle was towed to Sam Boswell GMC in Mt Dora, FL. The engine had seized up, and there were metal shavings in the oil filter which indicated a catastrophic mechanical engine failure.
Driving the vehicle with my family in it on merrit parkway in ct 230 am on May 10 th Car rpm start going up and making noises and felt like gear not shifting in few seconds later car all sudden on its own shifted to neutral as my speed 55-60 mph was during that moment. And screen on dash went blank dark .i was able to move to side of the road safe as possible .road is only two lane and no room to park on side . Immediately turn hazards lights on and try to restart the car and vehicle will not turn on . State troopers came and assisted us till tow truck came and vehicle get towed to dealer
Driving 79 mph total engine seizure. Check engine light came on and seconds later a low oil pressure light and turn off engine. Engine died and went into neutral and had to coast to side of highway in middle of nowhere at 11pm at night.
Im hearing ticking sounds when starting the engine and I reported it to my dealership service department and thay said thay don't see any issue
Engine failed, no check engine lights turned on. Needed to have the truck towed to a dealer
Starting at around 1300 miles, we noticed jerking upon acceleration. We took it into the dealership at 1500 due to a check engine light. They replaced the coil in cylinder 1. Then again at 3200 miles, we took it back in for the jerking sensation. They could not replicate the problem. At 4380 miles, we took it back to the dealer for the same issue. They drove it 580 miles and found the lifter valves in bank 1 to need replacement. The repair was performed and then on Saturday 1/17/2026, the car started giving check engine lights every time we accelerated. It would jerk non stop. The car hesitates during acceleration and feels like someone is pressing on the brake as we are accelerating, causing a jerking motion. Coming from a stop, the car feels like it has a hard time accelerating, almost like it is moving against a hard force to try to come up to speed. The car is at the dealer again today for this issue. It is unsafe to drive due to the hesitation during acceleration.
Vehicle Status: Brand New Current Mileage: Approximately 10,000 miles Incident Description On 1/8/26, while operating the vehicle on the interstate at highway speeds with cruise control engaged, the Check Engine light began to flash. Simultaneously, the vehicle’s warning system issued an alert stating that the engine oil was excessively hot. Immediately after these warnings, the engine began to emit a loud knocking sound and lost all power, shutting off completely while in motion. I was able to safely maneuver the vehicle to the shoulder of the road. Post-Failure Observations Upon inspection under the hood, I noted the engine was radiating extreme heat. I allowed the engine to cool completely before attempting a restart. While the engine attempted to turn over, it failed to start. Diagnostic Alerts Following the mechanical failure, I received multiple critical notifications via the GMC mobile app citing various engine failure errors. Summary Given that this vehicle is brand new with only 10,000 miles, a catastrophic engine failure of this nature is unacceptable. The vehicle was being operated under normal highway conditions when it became inoperable, posing a significant safety risk. I am seeking a full diagnostic review and a permanent resolution under the manufacturer's warranty.
I purchased this vehicle in May of 2025. It currently has 9840 miles on it. While driving in October the vehicle shut down and locked up. After getting it towed to a dealer I was told the diesel motor and the fuel system were blow and seized and need to be replace. The vehicle is still currently in North Carolina while I live in Virginia. Supposedly parts are in for repair for 3 weeks now and I still don't have my vehicle nor any info on when I will get back. Davenport GMC of Rocky Mount and GM have been rather useless in this process. I cant believe I am going through this with a $90,000 car that was four months old.
Reduced engine power warning light came on at approximately 7600 miles on our new 2025 Yukon xl. Dealer inspected and ultimately decided the engine needs to be replaced due to crankshaft end play out of spec. This is a know GM issue. Incorrect thrust bearing was installed from the factory. Gm did not inform us of this issue. This could have resulted in catastrophic engine failure and cause to be stranded on the road. Not ideal when it is -20 degrees in my hometown. Dealer finally replaced engine then had lane departure unavailable and lane assist unavailable warning lights. Dealer claimed this was unrelated but all safety equipment worked when we dropped it off. Now it doesn’t.
DuraMAX 3.0L LZ0 engine with defective crankshaft thrust bearing caused catastrophic engine failure requiring engine replacement. The event occurred at about 1,000 miles. There is a GM TSB that addresses this issue. This failure displayed all of the symptoms as described in the Technical Service Bulletin (TSB) 25-NA-307. The engine has been replaced by GM. There was only one cryptic dashboard message that "acceleration may be reduced", that briefly appeared and then disappeared, three days before the incident. With no check engine light, the mysterious message was chalked up to possibly a DEF low warning. DEF was added. The vehicle displayed no problems during those three days -handling normally. Then while at interstate speeds approximately 90 miles later, the warning that "acceleration is limited" flashed and the vehicle went into limp mode, shortly thereafter the check engine light illuminated. OnStar read the code - P06DD. The email from them stated the recommended action: "Service within 7 days." The following morning the vehicle was presented to a GM dealership service department. Loud "knocking" noises were originating from the rear of the engine compartment at that point in time. The service department reported the engine needed replacement and did so.
We purchased the 2025 GMC Yukon XL on February 26, 2025. While I was heading out on March 24, 2025 I had a total engine failure. No warning sign or warning lamps were present. We had the vehicle towed to Hurd Auto Mall in Johnston Rhode Island where we purchased it. We were told that the engine had seized with only 1,488 miles on it. We saw that over 870,000 GMC engines from 2021-2024 had this same issue and/or have been recalled. We are curious if the 2025 model also have this problem.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
