My Yukon Denali has started feeling weird over bumps, kind of floaty and unsettled at the back, and the ride height looks slightly off on one side when it’s parked. I know these have air suspension and magnetic ride, and I’ve heard both can be expensive when they go. It’s not throwing any warning lights yet, which makes me wonder if I’m imagining it or if it’s in the early stages of failing. I came across https://royalprinceautocare.com/brands/gmc/ while trying to find someone who actually understands these systems rather than a general garage that’ll just replace the whole setup. Has anyone dealt with this on a Denali and what was the actual fault? I’m hoping it’s a sensor or a leaking line rather than the compressor or a strut, but I’d rather know what I’m in for before I take it in.
