2025 Gmc Yukon

On multiple occasions the center screen has been non operational when we start the car and just shows a black screen. The volume knob and screen power button are non-responsive. When this occurs the backup camera is inoperable, which is mandatory safety equipment. the HVAC also cannot be adjusted which could cause a windshield fogging condition which is a safety concern. The vehicle has been to the dealer 3 times for screen problems and the issue has not been resolved. When this occurs the problem persists for a few ignition cycles or for up to a couple of days and then will start functioning again. We have not been able to determine any specific condition that is causing the failure.

Just over 6k miles, engine failure.

The engine has seized and was replaced

My engine completely failed on March 19, 2026 and it is currently at Sterling GMC in Bryan Texas waiting for a backorder engine as it needs to be completely replaced

My 2025 GMC Yukon's infotainment system has repeatedly failed. The huge center screen frequently goes black upon starting the car. Once the screen goes black you are unable to control literally dozens of the vehicle's features including but not limited to climate controls, safety features, heated/ventilated seats, gps, lane assist, the radio, no backup camera, etc. When the screen blacks out, the vehicle automatically turns the heat on to 76 degrees every single time and blows hot air from the front windshield defogger vents only. The list of features controlled by the touch screen is quite enormous. I have taken the vehicle to the GMC dealer four (4) times for software updates, none of which solved the problem and they have admitted they have no fix for this issue. The issue is widespread, as I have encountered literally hundreds of owners online like myself dealing with the very same problem; brand new cars that just do not work. GMC has done absolutely nothing to get to the bottom of this.

Engine failure while driving at 60mph that started with a loud knocking sound to eventual engine failure where it wouldnt turn over. Vehicle has 9600 miles and has had issues since day one of leaving lot requiring fuel injector, intake manifold gasket, lifter and rod with last fix being new coil and spark plug that supposedly fixed issue. The most recent engine failure put my family and kids in danager given 100 degree weather in middle of desert on a small highway with very limited cell service. Vehicle provided no warning lights. Vehicle was towed to dealership and I have not received an update. Vehicle has not been inspected by polive or insurance or others.

Vehicle went into limp mode while driving on the highway. Onstar said it was the transmission. Checked the oil and smoke was billowing out of the dip stick and there was no oil. None of the sensors indicated that there was low oil. After sitting and waiting for a tow truck rechecked the oil with the dipstick and there was oil in it. Now requires a new engine.

The contact owns a 2025 GMC Yukon. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly went into LIMP Mode with a limited speed availability message displayed. The vehicle was restarted; however, the failure recurred. The vehicle was taken to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 8,837

The 3.0L diesel motor failed around 5700 miles. The thrust bearing failed and the engine and the turbo needed to be replaced.

Engine started knocking and developed slow acceleration out of the blue. In addition car has locked up on freeway despite not having any cars around me. Its been in the shop for 3 days and still no diagnosis.

While driving on a highway, the vehicle intermittently suffers a sudden loss of engine power during acceleration, accompanied by a flashing check engine light. The most serious event occurred while merging into traffic when the vehicle failed to accelerate normally and briefly lost power, creating a risk of being struck by faster-moving vehicles. Pulling over and restarting temporarily restores normal acceleration, but the problem recurs. The malfunction appears consistent with an engine misfire/powertrain fault. An OBD scan has shown misfire-related diagnostic codes (random/multiple misfire and a cylinder-specific misfire). The condition is intermittent and often occurs after approximately 10–45 minutes of driving. The vehicle remains available for inspection. The vehicle has been presented to authorized service departments multiple times. Dealers reported they were unable to duplicate the issue during road testing and no lasting repair has been completed. The manufacturer has been contacted and the vehicle has been evaluated through authorized service channels, but the underlying cause has not been identified. This remains a safety hazard because it reduces acceleration in traffic. Incident list: • 10/25/2025 (~12:25 PM; ~3,108 miles): Loss of power while merging; flashing CEL; restart temporarily resolved. • 10/27/2025–11/04/2025: Intermittent recurrence, usually lasting a few minutes then clearing. • 11/05/2025 (~8:01 AM; ~3,641 miles): Flashing CEL and misfire/loss-of-power symptoms; taken for service. • 11/26/2025 (~10:06 AM): Another episode consistent with the same pattern. • 12/17/2025 (~8:21 AM): Another episode, including during travel to a service visit. • Ongoing: Episodes after ~10–45 minutes; sometimes requires restart to restore drivability. Observed codes: P0300 and P0301. Safety risk: loss of power during acceleration/merging increases risk of rear-end or side-impact collision.

The manufacturer has been contacted and the vehicle has been inspected/diagnosed through authorized service channels, but the underlying cause has not been identified. The failure continues to occur intermittently and is a safety hazard because it affects acceleration in traffic. Incident list 10/25/2025 (~12:25 PM; ~3,108 miles) — While accelerating to merge onto a highway, the vehicle lost power and the check engine light flashed. The driver pulled over, shut the vehicle off, restarted, and the condition temporarily resolved, allowing the trip to continue. 10/27/2025–11/04/2025 — The same loss-of-power/misfire behavior recurred intermittently, typically lasting a few minutes before clearing. 11/05/2025 (~8:01 AM; ~3,641 miles) — The check engine light flashed again and symptoms consistent with misfire/loss of power were present.

suddenly went into limp mode on the highway, engine had to be replaced due to bearing failure sending metal through the engine

This has happened twice. Once in November 2025 and then in January 2026. With super cruise engaged while going around a curve super cruse disengages and the steering wheel turns to driving straight. You have about one or two seconds to take control or crash. This happened while driving about 70 mph on interstate I 70 and next on Ohio 122 going about 45 mph. On I 70 it was a gentle curve and on 122 it was a much sharper curve. Super cruse must give a warning that it about to disengage that is much longer than one or two seconds.

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.

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
