MESSAGE SERVICE INTELLITRACK DRIVE WITH CARE CAME UP AND WHEEL LOCKED UP. THERE WERE NO MESSAGES BEFORE THE PROBLEM APPEARED.

I was traveling home from work and lost all power to the vehicle while driving. No warning lights, check engine lights came on. I was able to cross traffic and park it in a business place. I had it towed to a chevy dealership for diagnostic. They said that the timing chain came off and i would need a new engine. I had it towed to a auto mechanic shop for a second opinion and they gave the same result. The vehicle is only 4 years old with 92,000 miles on it. When i lost all power to the vehicle, I did not hear any strange noises.

While driving vehicle on 11/08/2025, vehicle made a popping noise and loss power. We were out of town and had to pay out of pocket to have vehicle towed to a dealership and hour away from our home. Dealership diagnosed issue with engine failure due to lifter fell and caused damage to cam shaft and bore. I will be without a vehicle for an additional 2 to 4 weeks waiting on a back ordered engine from GM, and continue making payments on vehicle as well. This issue seems to be an ongoing problem that GM is ignoring…….GM should compensate towing, car rental, and repair/ replacement charges due to failure.

Vacuum pump went out. It was a recall, previously on older models, but this model needs to

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)

Often times, on the heads-up display I would get "Steering Assist is Reduced Drive with Care" and my temp gauge will stop working and when I stop, my fan continues to run until I disconnect the battery for 20 secs.

Purchased used vehicle in June 2025 when purchased was not advised about an open recall vehicle loss power on 07-29-2025 called dealer advised that car had loss power while driving with entire family in vehicle. Brought vehicle in for checking said open recall they ran a scope test said it passed and only a high velocity oil change would be needed this was on 08-06-2025 two weeks later the vehicle loss power again while driving and caused a vehicle accident and bodily injury and GM states that this was an alleged issue when reported. Will not honor warranty on engine.

The forward collision automatic breaking sensor has already failed with only 15,000 miles. As well as the backup camera - it has already been replaced once

This is a follow-up to two previous complaints. The first complaint was filed around 5/22/25, and the second complaint was filed around 7/08/25. The complaint is related to a 2022 GMC Yukon that we purchased new. As reported in the previous complaints, we experienced several problems with the suspension and steering of the vehicle. The SUV continues to have a knocking, cracking, snapping noise coming from the front suspension when making a right or left turn, or u-turn. The dealer has made several attempts to fix it, but continues to occur. The warning lights continue to be set on and off, but not as often. The infoentertainment system as well. One of the other reported issues was the low oil warning light coming up and thus oil consumption. The SUV was taken to the dealer on 9/11/25, and the GMC service staff reported the SUV, during the summer hot days, was 1.9, almost two quarts. They asked to drive the SUV for an additional 2000 miles, and it was short by .9 quart. GMC claimed it is normal, but per their recommendations on oil changes, the vehicle would be 7 quarts between oil changes unless the driver checks the level every 1500 to 2000 miles. Not only was the information misleading as they denied to perform any services, but also is a safety concern for the damages it can cause to the vehicle, especially if it goes on safety mode. Around 7/24/25, we submitted a request for a buy-back to GM, which they approved 30 days later; however, they still have not made good on the promise, and the vehicle remains with these safety, operational, and mechanical issues.

The vehicle brake system completely failed. The brake pedal was depressed and several warning lights were illuminated on the dash, yet the vehicle would not come to a complete stop. At the time of failure, the abs light, parking brake light, traction control light, and collision light illuminated on the driver display. Additionally, the dash displayed a message requesting the driver to depress brake pedal hard and to “service ESC”. The brake pedal felt soft and would go all the way towards the floor. The vehicle had very limited braking and would not come to a complete stop. The vehicle was taken to a GM dealership for diagnosis and repair. The dealership confirmed that the brake system had failed and there was inadequate stopping force being produced. The entire master cylinder assembly which includes the hydraulic valve block and electric motor were replaced under warranty. The vehicle had 24,638 miles at the time of failure. Prior to the failure, there were zero indications that there were any issues with the brake system. Fortunately when the brake system failed the vehicle had just backed away from a parking spot and pulled forward towards a stop sign at low speed. The potential concern was that pedestrians, fellow motorists or the driver of the vehicle could have experienced significant injury or death due to the vehicle’s brakes failing.
