WHILE USING THE CUP HOLDER ON MY 2004 MERCEDEZ BENZ CLK VIN [XXX] COFFEE SPILLED AND CAUSED THE RADIO AND A/C UNIT TO MALFUNCTION. THIS RESULTED IN ALMOST $2,000 IN REPAIR COSTS. THE CUP HOLDER IN THE VEHICLE IS PLACED DIRECTLY ABOVE THE RADIO AND A/C CONTROLS. I KNOW THAT MERCEDES HAD PROBLEMS IN THE PAST WITH THE SLK MODELS WITH SPILLS CAUSING THE ELECTRONIC TRANSMISSION TO SHORT OUT. BASED ON THE DESIGN OF THE CUP HOLDER IS WOULD BE IMPOSSIBLE TO PREVENT SPILLING WHEN FACED WITH A SUDDEN STOP OR A HOLE IN THE ROAD. I REQUESTED THE REPAIR TO BE COVERED BY MERCEDES BENZ BUT THEY REFUSED TO HONOR MY REQUEST. SINCE THE DESIGN IS SO FLAWED, AND THE DAMAGE TO ELECTONIC EQUIPMENT SO FORESEEABLE IT IS WRONG TO DO THIS TO CONSUMERS. *NM UPDATED 07/16/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ON MONDAY, APRIL 4TH, I WAS DRIVING MY 2004 CLK55 CONVERTIBLE TO MY OFFICE, GOING 55 MPH AND LOST ALL POWER. I ATTEMPTED TO PUT THE CAR INTO NEUTRAL AND THE CAR GOING AGAIN, WITH NO SUCCESS. I WAS ABLE TO PULL OVER ON THE SIDE OF THE ROAD, AND THEN DRIVE A FEW MILES PER HOUR TO GET TO A SAFE PLACE OFF OF THE HIGHWAY. THE DEALER IS TELLING ME THAT THE TORQUE CONVERTER AND THE TRANSMISSION ARE BROKEN. THE TORQUE CONVERTER PART HAS BEEN ORDERED FROM GERMANY, AND IT IS ON BACKORDER FOR THE ENTIRE UNITED STATES. HAD THIS HAPPENED IN OTHER CIRCUMSTANCES, IT COULD HAVE LED TO A LIFE THREATENING ACCIDENT. I AM WRITING THIS LETTER TO YOU TO MAKE YOU FORMALLY AWARE OF THE PROBLEM, AND TO PREVENT IT FROM HAPPENING TO OTHER INDIVIDUALS.
