Took my 2016 Escalade out to a beginner-level dune trail near Al Qudra a few weeks back, nothing aggressive at all just some gentle cresting and sand dips, and since then the front air shocks have been losing pressure overnight making the whole thing look lopsided by morning like a car with a flat tyre but not quite. A buddy who works on American cars said these air systems can be temperamental even with small amounts of fine sand getting into the compressor or the strut bladders, but the dealer just told me outright to replace everything without even checking the compressor first, which felt a bit premature. I ended up digging around online to find a place that actually knows the platform and noticed a write-up mentioning Cadillac Suspension Service Dubai that talked about diagnosing the compressor and relay before condemning the whole system, which was exactly the kind of methodical approach I wanted to hear, so now I’m curious if any Escalade or CTS owners here have had air ride issues after a desert trip and whether the fix turned out to be something simple like a new compressor or deeper like the actual struts.
