I AM WRITING TO INFORM YOU OF A VERY TROUBLING INCIDENT THAT OCCURRED RECENTLY. I OWN A 2008 MERCEDES BENZ CL550 WITH 31,000 MILES ON THE ODOMETER. ON JUNE 16, 2014, THE SEATBELT ON MY VEHICLE WOULD NOT RELEASE FROM THE SEAT, LEAVING ME UNABLE TO BUCKLE MY SEAT. ON TOP OF THE OBVIOUS SAFETY HAZARD, ILLEGALITY OF DRIVING WITHOUT A SEAT BELT, CONSTANT DINGING FROM THE VEHICLE TO REMIND ME THAT I WAS NOT BUCKLED, WHICH DID NOT ALLOW ME TO SPEAK WITH MY CLIENTS BY PHONE IN THE VEHICLE, I HAD TO DEAL WITH VERY POOR HANDLING OF THIS MATTER BY MBUSA. I IMMEDIATELY BROUGHT THE CAR INTO FLETCHER JONES MERCEDES BENZ IN NEWPORT BEACH AND HAD MY SERVICE ADVISOR TAKE THE CAR IN TO CHECK OUT THE SEAT BELT MALFUNCTION AND CALLED ME TO TELL ME IT NEEDED TO BE REPLACED AND THAT MERCEDES BENZ USA (MBUSA) WOULD BE COVERING 75% OF THE COST OF THE PART AS A GESTURE OF 'GOODWILL', LEAVING ME WITH ABOUT $400 OF COSTS FOR LABOR AND 25% OF THE PART. WHILE I WAS APPRECIATIVE OF THIS GESTURE, I WAS NOT HAPPY ABOUT HAVING TO PAY ANYTHING DUE TO THE FAILURE OF A BASIC VEHICLE SAFETY FEATURE. HE SAID THAT I WOULD HAVE TO TAKE THIS UP WITH MBUSA DIRECTLY. I BROUGHT THE ISSUE TO THEIR ATTENTION OF MBUSA AND THEY REFUSED TO DO ANYTHING FURTHER. THE FACT THAT A COMPANY LIKE MBUSA WOULD NOT STAND BEHIND THEIR PRODUCT AND TAKE FULL RESPONSIBILITY FOR A VERY IMPORTANT ISSUE SUCH AS A SEAT BELT FAILURE IS QUITE DISTURBING. HIDING BEHIND A WARRANTY WHEN PEOPLES LIVES ARE AT STAKE IS AN IRRESPONSIBLE COMPANY LINE TO TAKE. I WOULD LIKE TO BRING THIS ISSUE TO THE ATTENTION OF THE NHTSA IN HOPES THAT THIS FAILURE IS DOCUMENTED AND READILY VERIFIABLE, SHOULD ANY UNFORTUNATE CONSUMER BE INJURED OR KILLED BY THIS DEFECTIVE PRODUCT IN THE FUTURE. *TR

MY 2008 MERCEDES BENZ CL550 IS HAVING A PROBLEM WITH BRAKE. THERE IS A THUG-THUG SOUND WHEN I PRESS DOWN ON THE BRAKE PEDAL. IT GOES AWAY ~2 SECONDS AFTER THE GEAR IS PUT INTO PARKING OR NEUTRAL POSITION. MERCEDES BENZ KNOWS ABOUT THE PROBLEM AND THEY TOLD ME THAT THERE IS ANOTHER CAR, A S CLASS, THAT IS HAVING A SAME PROBLEM. S CLASS IS 4 DOOR VERSION OF CL CLASS. MB TOLD ME THAT THEY ARE WORKING ON A NEW PART OVER 3 MONTHS AGO AND NOW THEY ARE TELLING ME THAT THEY ARE WORKING ON A SOFTWARE TO FIX A PRESSURE PROBLEM IN A VALVE. I DON'T UNDERSTAND THE DETAILS BUT IT SURE SOUNDS LIKE AN ENGINEERING ISSUE MEANING A DEFECT. MB SAID THE ISSUE IS LIMITED TO A VERY SMALL NUMBER OF VEHICLES BUT I AM NOT SURE IF THAT IS THE CASE. NOISE WAS NOT READILY NOTICEABLE BUT GOT LOUDER SO PEOPLE MIGHT NOT NOTICE IT UNTIL LATER. I AM VERY CONCERNED BECAUSE MY BRAKE PEDAL ALSO FEELS MUCH SOFTER AND WEAKER (NEED TO PRESS DOWN FURTHER). I HAD THIS PROBLEM FOR ~4 MONTHS. *TR
