NHTSA Complaint #11403853 — 2013 RAM 1500

TRUCK AIR SUSPENSION CONSISTENTLY FAILS DROPPING TO THE FRAME BUMP STOPS ON DRIVES (MOVING) WHEN AERO MODE IS AUTOMATICALLY ENGAGED. TRUCK DOES NOT RECOVER TO NORMAL RIDE HEIGHT AND PREVENTS PROPER HANDLING OF THE VEHICLE (IN MOTION). LONG DRIVES IN AERO MODE (ABOVE 60 MPH) CAUSES THE SYSTEM TO FAIL AND TRUCK BODY DROPS SHORTLY AFTER, OR FAILS COMPLETELY. TRUCK CANNOT HANDLE THE LOWERING MODES WITHOUT FAILING (AERO OR ENTRY EXIT). TRUCK WILL ALSO LOWER ITSELF WITHOUT WARNING (STATIONARY). WAS WASHING (STATIONARY) TRUCK AND CLEANING WHEEL WELL WHEN REAR OF TRUCK STARTED TO DROP. THIS IS A DANGEROUS SITUATION, ANYONE CHANGING A TIRE OR WORKING UNDER THEIR TRUCK COULD GET CAUGHT OR CRUSHED WHEN SUSPENSION FAILS OR DROPS WITHOUT WARNING. DRIVING WHEN SUSPENSION FAILS COULD CAUSE THE DRIVER TO LOSE CONTROL WHEN TRUCK COLLAPSES TO FRAME (NO SUSPENSION). THIS CAUSES THE TRUCK TO VIOLENTLY HOP OFF THE PAYMENT (TIRES LOSING CONTACT WITH ROAD) EVEN WITH THE SLIGHTEST BUMP IN THE ROAD. I AM THE ORIGINAL OWNER OF THE TRUCK AND IT'S BEEN TO THE DEALER 4 TIMES IN THE LAST 5 MONTHS. I'VE REPLACED THE AIR COMPRESSOR, VALUE BLOCK (WHERE AIR SUSPENSION LINES INTERSECT) AND AIR LINES. DIDN'T FIX THE ISSUE. I'VE COMMUNICATED THIS ISSUE TO CHRYSLER CUSTOMER SERVICE RAM. NO RESPONSE YET. THIS IS A DANGEROUS SITUATION AND RAM NEEDS TO RESOLVE THIS PROBLEM OR PROVIDE AND EFFECTIVE RESOLUTION \ FIX. PLEASE HELP. SUSPENSION PROBLEMS HAVE BEEN ONGOING FOR SIX MONTHS. 03/15 IS THE LATEST OCCURRENCE.
