On my 2014 GL 350 with 60K miles, whenever i return from a trip around town, 5 miles or more, there is a hissing sound (air leak) from the front passenger side (right) suspension. The SUV stays level and the air leak sound stops after a couple of hours. Happens consistently. However, once I raise the vehicle there is no air leak sound or loss of height after returning from a short trip or leaving the vehicle parked overnight.. Wondering if this is an issue or normal operation? Is it possible the airbag leaks only at normal level and is fine when raised? Appreciate any feedback.

FWIW, Airmatic makes totally normal sounds that happen to sound exactly like air leaks, especially when parked after a drive. As long as your truck is maintaining its height in all four corners (at any height setting) after sitting overnight it does not suggest a major leak.
