2014 NISSAN VERSA Structure Problems

THE CAR ON COLD DAYS AND SOME NOT COLD DAYS, AND COULD JUST HAD SAT FOR A COUPLE OF DAYS, WOULD FEEL/HEAR CRUNCHING SOUND (LIKE METAL BARS BEGINNING TO DISLODGE OR SOMETHING OF THAT NATURE) UNDER THE FLOOR BOARD AFTER ACCELERATION AND CAR STARTS TO MOVE. THIS IS ONLY ON DRIVER SIDE. IT DOES NOT HAPPEN EVERY TIME. I HAVE TAKEN IT TO THE DEALERSHIP NUMEROUS TIMES AND REPORTED THIS TO HAVE IT LOOKED AFTER. TO NO AVAIL, THE CRUNCHING PROBLEM IS YET TO BE DISCOVERED BY A SERVICE MAN. THEY HAVE YET TO FIND THE PROBLEM. IT HAS BEEN REPORTED FOR CHECK-UP AND DOCUMENTED MANY AND EVERY TIME I HAVE OIL CHANGES AS WELL. I HAVE BEEN REPORTING THIS PROBLEM TO THE DEALERSHIP SINCE 12/2013 AND NOW HERE IT IS MARCH 2015 THE PROBLEM STILL EXIST. *TR

WHILE I WAS DRIVING ONE DAY MY FOOT WAS ON THE GAS, CARS IN FRONT OF ME WERE COMING TO A SUDDEN STOP. I WENT TO REMOVE MY FOOT FROM THE GAS TO BRAKE AND MY SHOE WAS STUCK IN THE PLASTIC AREA NEAR THE GAS PEDAL. I HAD TO SNATCH IT OUT. SOME HOW THE PLASTIC SNAGGED ON TO MY SHOE. THIS WAS NOT THE FIRST OR LAST TIME, BUT THE SCARIEST. I'VE HAD THE VEHICLE SINCE FEBRUARY THIS YEAR, 2014. *TR ... UPDATED 03/19/15*BF
