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.
