general problems of the 2022 GMC Yukon

After a dealership repair to the rear differential, my 2022 GMC Yukon xl experienced a sudden driveline failure. A component detached underneath the vehicle, resulting in loss of control and immediate disablement. This occurred shortly after service and without warning. The vehicle is routinely driven at highway speeds while transporting multiple minor children. This appears to be a serious post-repair safety defect.

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.

On 5/22/2025, I filed a complaint with NHTSA, complaint number 11662650. In the complaint, I reported issues regarding safety concerns that began around October 2023 and were shortly after reported to GMC. Some of the reported issues were concerns with oil consumption due to warning lights coming on; parking warning sensors intermittently coming on; and what appears to be suspension issues as there continues to be a knocking, cracking, and snapping noise coming from the front suspension when making a left or right turn, along with a bumping when in motion, among other issues such as infotertainment that continues to be an issue. Recently, we took our SUV to a GMC authorized dealer since it was still under warranty and these issues continued to persist and it is getting worse. The vehicle was left around 5/28/25 and picked up on 6/17/25. However, less than a couple of weeks after, we started experiencing the same issues with the suspension as the knocking, cracking, snapping, and bumping is getting more obvious and worse, and it appears is affecting the steering and alignment of the SUV. Please update this information as there is a major concern with safety of the vehicle. Attached are some of the service records related to these issues. Should you need any additional information, please advise. Thank you.

I jumped in and turned the car on and started driving. Right away I noticed most of the warning lights were on. The first speed bump in the complex made me realize I had lost 80-90% of my brakes as if I had a broken brake line for example and steering was a little hard and pulling a bit to one side. I check underneath I did not have any leaks. I decided to take it to the dealer to have it checked. Dealer said they were not able to find anything and cleared the codes. Dash lights check engine lane depart drive assist abs brake.

See attached document for complaint.

Experienced a sudden loss of steering ability while driving, no collision occurred. Once the vehicle came to a stop still was unable to steer the vehicle.

Vehicle has been in for repair on (4) separate occasions for the same issue. Without warning, several error messages will pop up indicating problems with power steering, suspension, air bags, etc. In all there are 7 or 8 different error messages that all appear at once, but as soon as they do appear the power steering stops working. This has happened both from a cold start and while driving. In total the vehicle has lost power steering on 12-15 separate occasions. The service department at the dealership has had a hard time diagnosing the problem, but recently said that a faulty serial gateway module was to blame. After waiting 1. 5 months for a replacement part, I was told that the repair had been made and the vehicle was ready for pick up. Within 5 minutes of leaving the dealership the power steering failed again while driving, forcing me off to the side of a busy road. The same 7-8 error messages appeared on the screen.
