FRONT DRIVER AND PASSENGER SEATS BECOME LOOSE OVER TIME AND DEVELOP A CLICKING NOISE ON EVERY ACCELERATION AND BRAKING. MANY PEOPLE ARE REPORTING THIS ISSUE IN CAR FORUMS ONLINE AND THEY HAVE NOT BEEN ABLE TO FIND A FIX. DEALERSHIP EXPERIENCES ALSO DID NOT INVESTIGATE FAR ENOUGH FOR A FIX. MERCEDES RELEASED A SUPPOSED "FIX" IN THE FORM OF NEW BOLTS FOR THE SEATS BUT THESE BOLTS ARE NOT THE ISSUE. IT SEEMS TO BE THE PLASTIC GEARS IN THE SEAT MOTORS WEARING DOWN.
