2025 GMC Yukon

GM performed a vehicle wide Over the Air reprogramming of the modules incorporated in the VIP/Global B electronics platform in April, 2026. Following that my vehicle became totally dead. Key fob would not unlock the vehicle. Had to use the metal key, open the drivers door. Opened the door, nothing moved. No lights, no movement from anything on the vehicle. Opened the hood, charged the battery and tried to crank it. Would not budge. Starter would not engage. Disconnected the negative battery cable. Tried again. Still would not budge. After an hour of so of trying and using jumper cables from our other vehicle, still would not budge. I disconnected the negative battery cable from the right front fender ground and reattached it. It then cranked. Drove the vehicle 30 miles at interstate speed. 8 miles in city traffic. Drove home and parked it in the garage. Drove it abput 10-12 days later to get breakfast. Parked it, locked it with the key fob. Came back after getting food, key fob would not work. Opened it with the button on the door handle. Got In tried to crank it. Would not budge. Disconnected the negative battery cable twice, before it cranked, but would not drive. Message in dash said vehicle could not be driven. Finally got it cranked. GM never advised that the battery must have a 70% charge at all times for the electronics to work. Owner's manual contains no such statement. Vehicle is defective to the extent that it will leave me stranded in wherever the battery power is less than 70%. Dangerous to get stranded at night on a lonely road or highway, away from cities with tow trucks and competent service personnel. Vehicle in shop 32 days before dealer advised resolution. Modules bricked requiring engine control module and telematics module replacement.

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

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.

The progressive failure of the factory steering wheel adhesive on my 2025 GMC Yukon creates an immediate, active safety hazard during vehicle operation. The material failure and sticky glue are localized directly around the integrated heating element of the steering wheel. This failure severely impacts driving maneuvers as well as a potential electrical fire hazard. The liquefied glue residue is incredibly sticky and continually transfers to the driver’s hands, resulting in a compromised, slippery grip on the steering wheel. During active driving maneuvers, such as hand-over-hand turning, navigating sharp curves, the loose edges of the peeling leather and separating trim physically catch on the driver's palms. This restricts smooth wheel rotation, disrupts natural hand movement, and threatens a sudden, temporary loss of steering control. This manufacturing defect introduces severe driver distraction and physical interference with critical steering components while driving, compounded by a potential thermal or electrical defect in the steering wheel heating assembly.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

While driving on a highway, the vehicle intermittently experienced a sudden loss of engine power during acceleration, accompanied by a flashing check engine warning 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. 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. The

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 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.

In heads up display i was driving down at 74 mph in cruise control with nobody around or in front to cause the vehicle to suddenly come to a complete stop by its self, I had to hit the accelerator so we wouldn't get rear ended. Then when we got home I was backing in my driveway and the automatic brakes locked up stopping me from backing up.
