WINDSHIELD WIPERS STUTTER ON WINDSHIELD AND MALFUNCTION. THIS JITTERING ACROSS THE WINDSHIELD IMPAIRS VISIBILITY. WINDSHIELD IS NOT KEPT CLEAR, EVEN WITH NEW BLADES. WINDSHIELD CLEANERS ALSO PLUG UP CONTINUALLY MAKING WASHING THE WINDSHIELD WHILE DRIVING IN AREAS WHICH CREATE VISIBILITY PROBLEMS DUE TO DUST, BUGS, ETC....IMPOSSIBLE -- EVEN IF CLEANER FLUID TANK IS FULL. THE ENTIRE SYSTEM IS AN ISSUE. MERCEDES KNOWS THIS IS A PROBLEM. THE SUV HAS BEEN IN FOR REPAIR 4 TIMES SINCE PURCHASING LAST OCTOBER. THEY HAVE REPLACED IT EACH TIME, SAY THEY KNOW THERE IS A PROBLEM, AND SAY THEY WILL NOT REPLACE IT AGAIN. THEY SAY THAT NON-MERCEDES WINDSHIELD WIPER FLUID IS A PROBLEM (BUT THE FIRST 3 TIMES, THE FLUID WAS ORIGINAL MERCEDES FLUID). THEY SAY PUTTING THE VEHICLE IN A CAR WASH IS PROHIBITED -- A RIDICULOUS COMMENT. WHO DOESN'T PUT THEIR SUV IN A CAR WASH? THE MECHANISM IS FAULTY AND MERCEDES WON'T TAKE RESPONSABILITY AND IT IS A SAFETY PROBLEM.

WE WERE DRIVING DOWN THE FREEWAY, TRAVELING APPROXIMATELY 65 MPH IN OAKLAND, CA. THE WEATHER WAS CLEAR - NO RAIN AND APPROXIMATELY 60 DEGREES. ALL OF A SUDDEN, THERE WAS A LOUD NOISE LIKE A GUNSHOT AND OUR PANARAMIC SUNROOF SHATTERED. AT THE TIME, WE HAD A CARGO BOX ON TOP OF THE CAR (ON A FRAME THAT WAS NOT TOUCHING THE SUNROOF) SO IT IS UNLIKELY ANY PROJECTILE COULD HAVE HIT THE CAR. THE CARGO BOX WAS STILL AFFIXED TO THE CAR AND SECURE AFTER THE INCIDENT. IT WAS NOT AN EXTREME TEMPERATURE, NOR WAS THERE ANY EXTREME WEATHER (RAIN, SNOW, HAIL) AT THE TIME. THERE WERE NO UNDERPASSES NEARBY. MOST OF THE GLASS WAS CAUGHT BY THE SUNSHADE, BUT IF WE HAD THE SUNSHADE OPEN, THE GLASS WOULD HAVE ENTERED THE PASSENGER COMPARTMENT. WE HAVE OWNED THE CAR APPROXIMATELY TWO WEEKS AT THIS TIME.
