ENGINE
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 The engine has been replaced by GM.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 "acceleration is limited" flashed and the vehicle went into limp mode, shortly thereafter the check engine light illuminated. OnStar read the code - P06DD. The email from them stated the recommended action: "Service within 7 days." The following morning the vehicle was presented to a GM dealership service department. Loud "knocking" noises were originating from the rear of the engine compartment at that point in time. The service department reported the engine needed replacement and did so.

WHEELS, SERVICE BRAKES
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
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.

BACK OVER PREVENTION: WARNINGS, FORWARD COLLISION AVOIDANCE: WARNINGS
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 VIDEO.

ENGINE
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.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.
