When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2025 GMC Yukon

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

1 investigation is still open.

Loss of motive power due to engine failure post recall remedy

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s reca...

Recalls on the 2025 GMC Yukon

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

26V304000

WHEELS:HUB

General Motors, LLC is recalling certain 2025–2026 Cadillac Escalade, Escalade ESV, Chevrolet Suburban 1500, Tahoe, GMC Yukon, and Yukon XL vehicles with 24-inch wheels. Incorrect bolts may have been installed on the left and right front wheel hubs, which can result in the bolts loosening or deforming over time.

Risk: A bolt that loosens or breaks during vehicle operation can result in loss of vehicle control, increasing the risk of a crash.

25V876000

EQUIPMENT ADAPTIVE/MOBILITY:WHEELCHAIR RESTRAINTS/SECUREMENT:LATCH/ANCHOR:

Rollx Vans (Rollx) is recalling certain GMC Yukon, Sierra, Chevrolet Express 2500, Ford Transit, E-250, Toyota Sienna, Sienna Hybrid, Honda Odyssey, Chrysler Town and Country, Voyager, Pacifica, Dodge Grand Caravan, and Ram Promaster vehicles equipped with QRT-Deluxe and QRT-Max wheelchair restraints. Please refer to Rollx's recall report for specific model year information. The retractors may not lock, preventing the wheelchair from being properly secured.

Risk: An unsecured wheelchair can move during transit, increasing the risk of injury.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2026232 57 units in Canada

Wheels

Issue: This recall is for certain vehicles equipped with 24-inch wheels that had a dealer-installed accessory brake package or had the front hubs replaced during service. On certain vehicles, the wrong bolts may have been used during installation of the accessory brake package or during service or replacement of the front wheel hub bearings. As a result, the bolts could loosen and cause poor handling and a loss of control. Additionally, this could cause the front wheel(s) to separate from the vehicle. Safety Risk: A loss of control could create the risk of a crash. A wheel that separates could create a road hazard for others. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to replace the front left and right wheel hub bolts.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

UNKNOWN OR OTHER

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.

STEERING

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.

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.

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.

POWER TRAIN

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.
