Alternator/generator/regulator Problems of Mercedes Benz E350

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.

Spent over $2k just on diagnosis and wrong fixes. It started with problems cranking. I replaced the key fob, replaced the battery, replaced the alternator, have had mercedes diagnose with no answers. My usual mechanic diagnose with no answers. A european speacialist replaced the alternator and tensioner pulley. Took it to a friend and we discovered that there was a leak in the sunroof running down the side of the car into the battery compartment. At this point various problems are going on. The windows, door locks, radio, cranking, all intermittent but not always at the same time. Took it to another mechanic who said the sans module is bad, at least. An $800 fix, then they could move to the next module and the next. Also maybe unrelated but maybe not. Low car light came on. Engine 'died' (vehicle lost all power) while traveling at highway speed or will jerk down gears and only continue to function in drive @ 40mph or lower. I had to pull vehicle over on side of the road with no power assistance steering or braking. This problem occurred with no warning and at highway speeds creating an immense safety risk. Many others have reported the same issue with this and related cars for this and nearby model years. Like them, I wonder why there is no recall. Mercedes benz will not replace these defective parts willingly and there are many of these cars driving down our highways placing not only the passengers at risk but other drivers around them.
