THE AIR SUSPENSION SYSTEM DOES NOT FUNCTION PROPERLY CAUSING THE VEHICLE TO BOUNCE AGGRESSIVELY. SOMETIMES THE PROBLEM RECTIFIES ITSELF AND THE SYSTEM MIRACULOUSLY BEGINS FUNCTIONING AGAIN WITH PROPER FILL OF THE AIR SUSPENSION BLADDERS OR PROPER SENSOR CONTROL. I AM AWARE THAT THIS IS A COMMON FAILURE OF THIS MODEL VEHICLE AND YEAR. SO MUCH SO THAT THERE ARE COMPANIES DEDICATED SOLELY TO SELLING ONLY AIR RIDE SUSPENSION SYSTEMS/COMPONENTS AND AIR SUSPENSION CONVERSION SYSTEMS TO COMPLETELY ELIMINATE THE AIR SUSPENSION FROM YOUR VEHICLE AND CONVERT TO TRADITIONAL SPRING SUSPENSION. THIS IS CERTAINLY A HAZARD AND HAS CAUSED THE VEHICLE TO BOUNCE IN FAST AND SLOW SPEEDS. CONTROL OF VEHICLE ON FREEWAY AT 70 MPH BECOMES INTIMIDATING.
VEHICLE VIBRATES AT HIGHWAY SPEEDS. DEALERSHIP ATTEMPTED REPAIRS WITHOUT SUCCESS. DEALERSHIP ADVISOR SAID THEY COULD NOT PROPERLY DIAGNOSE PROBLEM. *TR
