Air suspension suddenly lost air

Both rear struts lost air completely all of a sudden stopping at the light. Both rear struts replaced a year ago. Tried raising the car with button front raised but rear didn’t. Dash indicated car was rising but there wasn’t any indication the rear went flat.
Any ideas?
Thank you,

Welcome to 2CarPros.

Craig, either one of the new shocks has failed or a pressure supply line has come apart or broken. The hoses are not easy to get to, so lets start with the easy ones. Check both rear shocks where the air hose connects. Make sure nothing has come apart or has been damaged. See if you can hear any leaks near the lines that would indicate a leak. Often times, I will take a spray bottle and fill it with a bit of dish soap and water and spray the lines. If there is a leak, it will bubble.

Take a look at pic 1. I circled two things to check on both sides. Let me know what you find as well as if a warning indicator has turned on.

Take care,
Joe
