2014 LEXUS ES 350 Structurebody Problems

ON 03/18/14 (MORNING), AN INDEPENDENT MECHANIC INSPECTED AND CONCLUDED THROUGH TESTING THAT ONE OF THE ENGINE MOTOR MOUNTS WAS BROKEN/DEFECTIVE AND NEEDS TO BE REPLACED. I WAS PRESENT FOR THE TEST AND THE MECHANIC WALKED ME THROUGH EACH STEP AND POINTED OUT EXACTLY WHAT WAS HAPPENING AND WHY. ON 03/19/14 (MORNING), LEXUS DEALERSHIP DENIES ANYTHING IS WRONG WITH THE MOTOR MOUNTS AND CANNOT "REPLICATE" THE PROBLEM. ON 03/19/14 (AFTERNOON) I MET WITH THE LEXUS SERVICE TECHNICIAN AND WE PERFORM THE EXACT SAME TEST AS MY INDEPENDENT MECHANIC. ALTHOUGH LEXUS CLAIMS NO REPAIRS WERE DONE SINCE THEY DIDN'T FIND A PROBLEM, THE TEST NOW SHOWS THE MOTOR MOUNTS AS BEING IN WORKING ORDER (MAGICALLY) ALTHOUGH LEXUS DENIES NOTHING WAS EVER WRONG AND NOTHING WAS REPAIRED BY LEXUS, ITS APPARENT TO ME AND MY MECHANIC THAT REPAIRS HAVE BEEN MADE BY THEM TO FIX THE PROBLEM WITHOUT IT BEING DOCUMENTED. *TR
