I would say be careful and test drive over a lot of bumps and dips my 2015 Denali has been in the shop a total of six times now with no repair as the magnetic ride shocks are locking up when they hit a bump or dip. I have had the gm engineer at the dealership to look at and text drive the truck and he felt the shocks lock up and can reproduce the problem with someone jumping up or down in the bed of the truck. He also hooked up a computer to the bcm and shut off the magnetic ride shocks and the problem went away. There only excuse so far is its a new suspension system and they are not sure what to do with. All I hear so far is give it more time for the dealership and the engineer to see if they can figure out something. They said they tested the other two Denali's they had on the lot and they can get them to do the same thing but when I asked to test drive them I cannot get them to do the same as my truck.
