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.

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.
