WHILE TRAVELING AT 55MPH THE STEERING SUDDENLY FELT VERY STIFF AND HARD TO MOVE. HAD TO APPLY BRAKES WHEN IT SEEMED I COULDN'T NEGOTIATE A CURVE IN THE ROAD. THE STEERING RETURNED TO NORMAL SHORTLY AFTER APPLYING THE BRAKES. THE STEERING PROBLEM OCCURRED AGAIN IN A LOCAL SHOPPING CENTER PARKING LOT AT SLOW SPEED. RETURNED THE CAR TO THE DEALER SERVICE CENTER. THEY PERFORMED A SOFTWARE UPDATE AND STATED THEY COULDN'T FIND ANY PROBLEMS WITH THE STEERING. WITHIN 3 DAYS THE PROBLEM REAPPEARED AT SLOW SPEED WHILE STEERING THROUGH BARRIERS ENTERING A LOCAL AIR FORCE BASE. THE NEXT DAY (4 DAYS AFTER DEALER SERVICE) THE WIFE HAD THE STEERING LOCK UP AT SLOW SPEED IN A LOCAL GROCERY STORE PARKING LOT. SHE COULD NOT MOVE THE STEERING WHEEL AT ALL. SHE SHUT OFF THE ENGINE, RESTARTED THE ENGINE, AND THE STEERING RETURNED. THE SAME THING HAPPENED AGAIN ON THE WAY HOME AFTER GROCERY SHOPPING. SHE IS NOW AFRAID TO DRIVE THE VEHICLE ON THE HIGHWAY. RETURNED THE CAR TO THE LOCAL DEALER FOR SERVICE. WE HAVE ONLY HAD THE ML350 THREE WEEKS. COULD NOT BELIEVE THE PROBLEM HADN'T BEEN DISCOVERED BEFORE BY THE PREVIOUS OWNERS OR THE SALES MANAGER THAT WAS USING IT AS A DEALER VEHICLE. *TR

THE VEHICLE STALLED AFTER THE FIRST WEEK OF PICKING UP A BRAND NEW VEHICLE AT A TRAFFIC LIGHT. DEALER REPLACED HIGH PRESSURE FUEL PUMP, BUT THE VEHICLE CONTINUED TO STALL ON MANY DIFFERENT SUBSEQUENT OCCASIONS RANDOMLY. THERE WERE A FEW TIMES THAT THE CAR DIED REPEATEDLY ON CONSECUTIVE DAYS. DEALER WAS UNABLE TO DIAGNOSE THE EXACT PROBLEM SINCE IT OCCURS RANDOMLY, AND MERCEDES WAS UNABLE TO PROVIDE ANY RESOLUTION TO REMEDY STALLING ISSUE. DEALER MENTIONED THAT MERCEDES HEADQUARTER AWARE OF THE SYMPTOMS BUT HAS NO FIX IN THE MEAN TIME. ALTHOUGH THE ENGINE HAS STALLED MOSTLY DURING A COMPLETE STOP, IT COULD POSSIBLY STALL WHILE THE VEHICLE IS IN MOTION, WHICH COULD POSE A GREATER RISK TO DRIVERS ESPECIALLY FEMALE DRIVER WITH A BABY INSIDE WHO DOES NOT KNOW HOW TO REACT APPROPRIATELY IN SUCH ENDANGERED SITUATION. *TR
