2025 GMC YUKON Recalls, Complaints & Safety

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 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. After pulling over and restarting the vehicle, normal acceleration temporarily returned, but the problem has recurred multiple times. The malfunction appears to be related to an engine misfire or powertrain fault because the check engine light flashes during the events and an OBD scan has shown misfire-related diagnostic codes (random/multiple misfire and a cylinder-specific misfire). The condition is intermittent and typically occurs after the vehicle has been driven for approximately 10–45 minutes. The vehicle remains available for inspection. The vehicle has been presented to authorized service departments multiple times for diagnosis. The dealerships have reported that 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 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.

ENGINE died rattling sound undeer car shaking loss of power

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

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.

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 bought a brand new 2025 GMC Yukon AT4 3.0 Diesel on 8/16/25 (had 213 miles on). A month later, with only 2000 miles on the vehicle, I was driving down the road and got a warning "reduced acceleration, drive with caution". Car would hardly accelerate. Had it towed to the dealer on 9/22/25. They found metal shavings in the engine oil. Said there was a quarter inch play around the camshaft (manufacture defect). Told me I need a completely new engine. It's now 12/2/25 and I still don't have a car, and mine hasn't been repaired.

On November 5, 2025, this 2025 diesel GMC Yukon Denali brand new vehicle went into "limp mode" 75 days after purchase with 3,957 miles on the odometer. Vehicle began to decelerate on a busy road. Warning lights went on to indicate that accelerating was no longer possible. Other fast-moving vehicles on the road came very near to the Yukon and quickly passed it/weaved around it, jeopardizing the lives of this Yukon's driver and occupants. At times, the Yukon diesel vehicle would only reach 15 MPH. Vehicle eventually driven to nearest GM dealership. The GM dealership service center reported a P06D code and reported that the engine experienced catastrophic engine failure. A new diesel engine has been ordered but is not yet available to the dealership for installation. (The dealership also reports that two other new GM diesel SUVs are waiting on new engines due to catastrophic engine failure.)

On October 21, 2025, with only 4,197 miles on my Yukon, the vehicle suddenly died while in drive in a parking lot. The vehicle would not restart or shift into neutral. I contacted OnStar, who arranged for the vehicle to be towed to the nearest GMC dealership. Since that date, the vehicle has remained at the dealership and has been diagnosed as needing a complete engine replacement due to metal shavings found in the engine. There were no warning lights, messages, or performance issues prior to the failure. This incident was both unsafe and alarming, as the vehicle shut down unexpectedly without any warning while I was driving. I would like to understand how such a major failure could occur on a brand-new vehicle with so few miles.

I'm reaching out because I've encountered a really concerning issue with my 2025 GMC Yukon AT4 Ultimate. There's a really loud popping noise randomly coming from the speakers that's honestly quite startling and dangerous while driving. Most recently, it scared me so much that I swerved off the road and nearly crashed. If you review online forums, you will find that this has been experienced by other owners as well. I've tried to resolve this through your usual service channels, but my concerns have been dismissed without any recommended action to ensure my family's safety. After scheduling with my local GMC dealership they couldn't replicate the noise and sent me on my way. I also brought it up with GMC Customer Care, and they suggested I try to record the sound, or keep bringing it in for service if it happens again. The problem is if I tell them it keeps happening again, what good will it do? It's a loud pop coming from the back speaker area. Even if they had 7 technicians hearing it at the same time, how will that make a difference. I need them to start testing components and replacing them one by one until its resolved.

Driving through the intersection of N. Scottsdale Road and E. Bell Road in Scottsdale AZ my collision warning red light flashed on the screen and the engine turned off. This caused me to lose forward propulsion and forced me to navigate to the side of the road to avoid being hit by another car. At Van’s GMC, the service manager told me that we experienced a catastrophic engine failure and that the engine seized. Vehicle has been inspected, but I have not received an official diagnostic even though I have requested. There were no warnings or indications that the vehicle was compromised prior to the engine turning off.

PLEASE SEE ATTACHMENT:

The wireless charging pad in the vehicle below the climate control system. Yes, it is. The charging component malfunctioned and overheated the back of my phone when it was set in the console while driving. I had no intention of charging my phone, but instead place my phone down while driving. When I picked up my phone at a stop light, I laid it in my inner thigh when the light changed. The burning was so intense and unexpected I swerved into oncoming traffic and lost control, momentarily of the vehicle. I have recreated the incident in a controlled environment myself and the issue is still active. I am happy to have the issue confirmed independently. I gave notice to the dealership after it happened with no concern or further investigation. No, the vehicle has not. No, no warning at all. In fact this is my 3rd GMC Yukon since 2016 and all 3 have had the wireless charging pad, I have had the same phone as my last one. I never had an issue or experienced anything like this.

My vehicle, with only 2,400 miles on the odometer, has been diagnosed as requiring a full engine replacement. While driving on the interstate, a warning message appeared indicating reduced acceleration. I was able to exit the freeway safely, but the vehicle could no longer maintain adequate speed to match traffic flow. Prior to this, the check engine light came on, but no issues were reported in the vehicle’s status system. I contacted OnStar, and they advised me to take the vehicle to a dealership within seven business days. It has since been at the dealership awaiting parts. Upon further research, I discovered that this issue appears to be widespread. General Motors has issued a technical bulletin addressing the problem, which involves complete engine replacement. Additionally, the audio system intermittently emits a loud crashing noise that is startling and potentially dangerous—it has caused me to veer off the road due to its intensity. This issue also seems to affect other 2025–2026 Yukon and Tahoe models.

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.

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.

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.

While engaged, Super Cruise failed to detect lines on road on a bend and launched the vehicle in the opposite lane without warning. This has occurred two separate times. First time was in late June 2025 on the PA Turnpike. Traveling at 70 mph. It was a left hand bend in the road where it failed to detect lines on road and thrust vehicle into the right hand lane. Happened so fast there was no time to react. In addition Lane Keep Assist was active as well. Also note lines were present on the left and right side of vehicle. Luckily no one was beside me. Second time was one a two lane road going 45 mph. Same scenario as first. Vehicle DIC stated it had lost road lines and threw me into the left lane without warning. Luckily no car was coming or it would have been a head on collision. Same message o display vehicle lost lines on road.

The console screen that control many vehicle functions will often not boot up when the vehicle is started. Screen crashes have also happened while underway. The screen will be unresponsive to both touch and physical controls. Systems unable to be controlled include safety cameras and sensors, climate control, navigation, gauges, infotainment and others. I have attached a diary of specific issues and work arounds attempted. The dealership and GM do not appear to have methods of fixing the issue at this time.
