Does any one know what is causing this? The suspension was lowering on the Highway at set speed and then BAM!! "Air Suspension Needs Service" Warning was thrown across the dash and then it jumped right back into the standard setting! And so I continued to drive home and the car was parked for 1 and 1/2 hours and the warning was gone! And then as I hit the highway again and the car was lowering, and the warning message appeared again and car went back into standard mode. So has anybody else had this issue?
