2025 GMC Yukon XL owner complaints

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.

Reduced engine power warning light came on at approximately 7600 miles on our new 2025 Yukon xl. Dealer inspected and ultimately decided the engine needs to be replaced due to crankshaft end play out of spec. This is a know GM issue. Incorrect thrust bearing was installed from the factory. Gm did not inform us of this issue. This could have resulted in catastrophic engine failure and cause to be stranded on the road. Not ideal when it is -20 degrees in my hometown. Dealer finally replaced engine then had lane departure unavailable and lane assist unavailable warning lights. Dealer claimed this was unrelated but all safety equipment worked when we dropped it off. Now it doesn’t.

DuraMAX 3.0L LZ0 engine with defective crankshaft thrust bearing caused catastrophic engine failure requiring engine replacement. The event occurred at about 1,000 miles. There is a GM TSB that addresses this issue. This failure displayed all of the symptoms as described in the Technical Service Bulletin (TSB) 25-NA-307. The engine has been replaced by GM. There was only one cryptic dashboard message that "acceleration may be reduced", that briefly appeared and then disappeared, three days before the incident. With no check engine light, the mysterious message was chalked up to possibly a DEF low warning. DEF was added. The vehicle displayed no problems during those three days -handling normally. Then while at interstate speeds approximately 90 miles later, the warning that "accelerat

On May 6, 2026 while driving on the interstate, the vehicle automatically shifted into Neutral, and lost all engine power. The vehicle would not shift back into drive or even 4x4 neutral to be towed. The vehicle was towed to Sam Boswell GMC in Mt Dora, FL. The engine had seized up, and there were metal shavings in the oil filter which indicated a catastrophic mechanical engine failure.

We purchased the 2025 GMC Yukon XL on February 26, 2025. While I was heading out on March 24, 2025 I had a total engine failure. No warning sign or warning lamps were present. We had the vehicle towed to Hurd Auto Mall in Johnston Rhode Island where we purchased it. We were told that the engine had seized with only 1,488 miles on it. We saw that over 870,000 GMC engines from 2021-2024 had this same issue and/or have been recalled. We are curious if the 2025 model also have this problem.

Driving 79 mph total engine seizure. Check engine light came on and seconds later a low oil pressure light and turn off engine. Engine died and went into neutral and had to coast to side of highway in middle of nowhere at 11pm at night.

Im hearing ticking sounds when starting the engine and I reported it to my dealership service department and thay said thay don't see any issue

Engine failed, no check engine lights turned on. Needed to have the truck towed to a dealer

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 l

keep quit working when i was driving , i just pick up from delearship for i another issue with on-star and is not part available is been there for over month not fix and now the brakes issue

Roughly one to two times per day, a notification pops up on the infotainment screen stating that the brakes need to be serviced due to the brake assist system failing. The vehicle has been brought to 3 different dealerships and none of them know what the problem is, how to fix it, or whether it is safe to drive the vehicle still. The brakes seem to be working fine, however, it is concerning that even if the notification is safe to ignore, the brakes could indeed end up failing and the driver may not be aware due to receiving frequent brake failure notifications per day.

The car was purchased on 8/15/2026. On November 6th 2026 with 3051 miles on all the gauges, electronic dashboard, gps , climate controls, heads up display failed while car was in driving. There was no way to tell what speed the car was going, the gas level, rpms, engine temperature, etc. Navigation failed, Cruise control failed, I was unsure if the emergency braking system failed. The dealership responded there was over 27 error codes on the car computer. There was no way of knowing if the signal lights were working. There was no prior warning to this failure. The GMC service department at the dealership confirmed the failure and said it needed to replace the radio control module. It took 70 calendar days for a replacement module to be provided, and a new software patch was uploade

The infotainment and instrumentation cluster will reboot while driving. This has happened multiple times while on the express way and while using super cruise. When the event happens the infotainment and instrument cluster will turn black for multiple minutes rebooting. At times they do not successfully reboot and forces the vehicle to pull over stop and force a system reset.

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

My brakes stopped working randomly. Alarms started going off in the car. Thankfully I was able to quickly turn right instead of rolling into traffic. This was terrifying and could have caused a very serious wreck.

The rear view camera is not sufficient for full time use. The camera is positioned too low and during times of dawn/night/dusk if a truck of similar size pulls up behind you, your camera is completely blinded by headlights. Leaving you unable to see anything in the rear view camera. This is a serious safety concern as you are unable to see if anyone is approaching your vehicle to cause you harm. The low camera placement also does not allow for an acceptable/comparable view as using the rear view mirror. The zoom does not pull out far enough to see multiple lanes of traffic and even during the daylight, if someone is approaching the vehicle to cause you harm, it would not be visible. The camera placement only allows you to view the front grill or hood of the vehicle behind you.

On August 9th at 5:30PM roughly, while attempting to park using the vehicle’s Park Assist feature, the system failed to function properly—specifically, it failed to detect a pole at the rear of a parking space, did not slow or brake the vehicle, and was not even aware it would contact the pole. It then collided with the pole. Also, intermittently the forward collision alert system either does not alert for similar circumstances as it just previously did. Seem untrustworthy. Scary. GM's product allegation team (PAC) had all of the necessary information to show the system does not work 100% of the time (I have it all on video and submitted that) and they denied my claim and refused to admit a system failure even when given the videos showing the park assist failing to engage properly ON VIDE

Transmission malfunctioned 4 separate times. Engine and service transmission light came on. Vehicle shifted hard and became immobile at certain times. 4 tropes to a dealer for repair. Latest repair was replacing ECM and problem still persists.

I am writing as the owner of a new 2025 GMC Yukon XL AT4 VIN: [XXX] , purchase date: 01AUG2025, from Elizabeth City GMC, Elizabeth City, NC. This vehicle, equipped with the 3.0L Duramax diesel engine and Super Cruise hands-free driving assistance, was purchased for safe family travel, including space for my wife, our 21-year-old daughter, and our family dog(s). At approximately 4,300 miles—well within the 3-year/36,000-mile bumper-to-bumper warranty—this truck suffered a catastrophic right-rear brake failure directly attributable to a dealer-installed GMC-approved Brembo Performance Brake Upgrade Package, resulting in a near-fatal highway incident and profound emotional hardship for my family.
