My Escalade’s ride feels off anyone else had this?

Hope you’re all having a good week. I’ve got a bit of a concern with my Cadillac Escalade that I’m hoping someone here can shed some light on. You know how these cars usually glide over everything like magic? Well lately, mine has been feeling a bit floaty and unstable, especially when I’m driving on the highway near Jebel Ali or going over those longer bumps. It almost feels like the back end sags a little more than usual too, which makes me think it might be the air suspension acting up. I’ve been reading up on common issues and it seems like these systems can get finicky over time, especially with all the heat and dust here. I want to get it checked by a proper specialist who knows these American luxury cars inside out, and I actually found a place that does Cadillac suspension system service Dubai with good reviews online. Has anyone here used them before, or can recommend a workshop that really understands the magnetic ride control or air suspension setups? I just don’t want to hand it over to some random garage that’ll end up making things worse. Appreciate any help or experiences you can share!
