2025 GMC YUKON Complaints

Warning about reduced acceleration and need for immediate servicing. Dealership reports notice about this issue by using diagnostic codes. Needs engine and turbo charger replaced. Vehicle has only 6500 miles on it.

Driving along on an empty road and my panoramic sunroof back glass exploded it sounded like a gunshot going off. Could have caused a wreck it was so loud and scary.

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.

Brand new engine blew up while driving. It had 2,000 miles on it. It has been replaced but am worried it will happen again

Engine Failure confirmed by dealership. Engine being replaced. Knocking sound and went in to “limp mode” and check engine light. Dealer stated it had issue with crank shaft causing metal in the oil. 5,117 miles at time of failure. 3.0 L Duramax diesel

2025 Yukon Denali - Purchased in July of 2025 Specifically to pull air stream trailer. Vehicle Was equipped with necessary tow package for this purpose! #1 problem: Went into limp mode, stopped in traffic, towed to dealer. One week to repair and replace fuel system. ( under 700 Miles ) #2 Problem: Went into limp mode while pulling trailer, vehicle lost all the transmission fluid on ground. In shop sixteen days waiting for new transmission parts. ( Under 700 Miles ) #3 Problem: Vehicle stopped in traffic, towed to dealer where it was determined it needed new engine. In shop Nov 27, 2025, still in shop as of Jan 14, 2026. No ETA on engine or delivery. ( Under 2000 Miles ) #4 Problem: During last failure attempt to use "on star" failed, still not resolved. This vehicle is a danger to the owner and its passengers as well as others when it simply stops working in the middle of a busy highway with a 23' trailer in tow. Not to mention I have $160,000 invested in a car and camper I have yet to be able to use.

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.

The image module system has completely failed and never worked in the Yukon. Then it would brake while still accelerating.

My 2025 GMC Yukon AT4 Ultimate experienced reduced acceleration, and I immediately took it to the dealer. The dealer concluded it was a thrust bearing failure, and GM has authorized a complete engine replacement. I wanted to report this issue, as I believe it represents a potential safety concern. I would like to clarify whether GM has identified the root cause of this problem and redesigned the replacement engine to prevent recurrence. Additionally, I want to be able to track the replacement engine through its serial number for documentation purposes. I am submitting this report to formally document my concern. While GM has acknowledged the thrust bearing issue through a memo #25-NA-307, they have not confirmed whether the redesigned replacement engine will prevent this failure from happening again. Please advise. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
