MY 2003 E320 SEDAN BATTERIES IS CONSTANTLY DRAINING AFTER THE VEHICLE SITS FOR 6 OR MORE HOURS. I HAVE INCURRED COSTLY EXPENSES IN REPLACING BOTH THE REAR LOAD & FRONT SMALL AUXILIARY BATTERIES TO INCLUDE LABOR COST AT AN AUTHORIZED MERCEDES REPAIR SHOP. OCTOBER 2019 I TRIED TO ACCESS THE CAR USING THE KEY KNOB, HOWEVER NO POWER TO ACCESS THE VEHICLE NOR ACCESS THE TRUNK. NOVEMBER 2019 THE VEHICLE FOG, INTERIOR & REAR TAIL LIGHTS BEGAN TO FLASH ON & OFF AND THE SECURITY ALARM BEGIN TO SOUND WITH A WEAK LIKE BATTERY SOUND WITHOUT THE USE OF THE SMART KEY, DECEMBER 2019 THE SAME OCCURRENCES BATTERIES WERE DRAIN, NO POWER & RECENTLY FEBRUARY 2019 SAME OCCURRENCES NO POWER TO VEHICLE. I HAVE PURCHASED NEW BATTERIES & A NEW ALTERNATOR & STILL THE SAME ISSUES OF BATTERY DRAINING. THE AUTHORIZED MERCEDES REPAIR SHOP HAS CONDUCTED A INSUFFICIENT VOLTAGE TEST & ELECTRICAL TEST TO FIND NO ISSUES? THESE OCCURRENCES HAS COST ME EXCESSIVELY & I WANT MERCEDES BENZ MANUFACTURER TO TAKE RESPONSIBILITY IN A RECALL TO ALL CONSUMERS WITH THIS MODEL EXPERIENCING THE SAME OR SIMILAR ELECTRICAL ISSUES OUT OF THE CONSUMER CONTROL. I PURCHASED THE VEHICLE & EXPECTS MERCEDES TO OWN UP TO THEIR CUSTOMER SERVICE SLOGAN. I REQUEST A RESPONSE FROM MERCEDES HEADQUARTERS TO THOROUGHLY INSPECT MY VEHICLE THEIR DEFECTIVE PRODUCT I PURCHASE & MAKE GOOD ON THIS REOCCURRING BATTERY DRAIN ELECTRICAL ISSUE.
