What drivers notice on this 2021 Cadillac Escalade

Owners of a 2021 Cadillac Escalade typically first notice a problem with their air ride system when the vehicle's rear end appears to be sitting lower than usual, even when unloaded. This sagging can be more pronounced after the vehicle has been parked for a while, as air slowly leaks from the system. Beyond the visual cue, the ride quality itself deteriorates significantly, becoming noticeably rougher and less comfortable, especially over bumps or uneven surfaces. You might also hear the air compressor running more frequently or for extended periods, struggling to maintain the correct ride height. Other key indicators include:
