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.
