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.

My wife and I purchased a new 2022 Yukon around July 4, 2022. The vehicle came with a 36k or 3 years warranty. Around October 2023, we experienced several safety concern issues with the SUV and around 11/01/23, we reported these issues to a GMC dealer. Around 11/01/23, we took our SUV for service at an approved GMC dealer and reported issues with the steering suspension such as a knocking, snapping, and cracking sound when making a turn, and a bumping when making a U-turn or left turn into a parking spot. We also reported issues with the parking and key sensors. We were informed the issue was fixed and that some suspension bolts were loosed and needed to be torqued. On 1/29/24, we took the SUV back for some of these same reasons after other dealers declined to take our SUV under warranty. Once more, the issue was temporarily fixed. We have now scheduled another appointment for these same reasons of knocking, cracking, and bumping when coming from the front suspension and when making a turn or U-turn. In addition, we are now experiencing oil warning lights for a second time as oil comsumption. We believe these are serious safety issues, especially with any potential failure of the suspension under rain, fog conditions, and the lack of resolution and wonder if other similar issues have been reported or experienced by similar drivers of these vehicles. Attached find copies of the work orders. Should you need any additional information, please advise. Thank you.

My 2022 GMC YUKON DENALI has been at dealership multiple time for defective air ride suspension. The message says "service leveling system" once that show's it's a matter of time the vehicle will slump down. The passenger side air bag keeps busting creating a safety hazard for my family and others on the highway.When problem occurs the vehicle slumps down on front suspension and will bounce out of control when driving on highways and over bridges. It has now been in shop 4 times for the same problem. Dealership has been extremely helpful on trying to fix the problem, but there's definitely something serious going on and GM needs to look into making this right before someone get's hurt driving this vehicle.

We repeatedly received an error saying -??Vehicle too high, drive with caution-??, at which point, the suspension adjustment controls would not work and I could not lower the vehicle. The service department has had our vehicle for over 2 months now and I am unsure if they were able to duplicate this particular issue, but we did photograph the warning. We have had multiple other electronic issues with this vehicle and feel we were sold an unsafe 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.
