1 Electrical System problem

Failure Date: 12/08/2022

New S500 benz, 1700 miles on the car, 2 months on the road only. Issues started right off the batt after purchasing this new S500. Car refuses to start daily, check engine light, 12v battery light, 48v battery needs service light, come on even tho the cars voltage is not low and is driven daily on highway. Took to the dealer, dealer says car needed to be driven more even tho its driven daily. Dealer stated voltage of the 12v battery was low, they charged the battery manually and stated that the cars ecu recorded a voltage problem. They cleared the ecu and released the car after 1 week in the shop under warranty. Next day the car was driven after it came out the shop, the car again gave a check engine light, 12v battery light, 48v battery needs service warning message. After driving the car for a bit the car completely went haywire. All interior electrical went out. Center counsel not working, dash console showed over 30 warning lights and messages ranging from electrical to low brake fluids including check engine light, srs inoperable message, and many many more messages telling me to stop driving the car. Car is scheduled to be taken back to the dealer for another checkup. This time car must be towed in since it refuses to even turn on or to unlock the doors or windows. This car seems to be having major electrical issues as well as major computer problems. This car is unsafe to drive since it can stall out while driving. At this point I will be contacting mercades benz corporate to speak to someone about these major issues. As it stands the dealership is unaware of how or why the car is acting this way and do not know how to fix it. A true lemon indeed. Please view pics attached.
