EQE 350+ known problems or individual problems

Meanwhile I had 2 breakdowns:Panne 1: After a 350km drive the vehicle was parked and could not be started 15 minutes later with the error message: Battery symbol malfunction -> Towing prohibited. As a result the vehicle was towed to Mercedes. Was about 10 days in the workshop. Cause 12V battery was empty due to a software bug. AI was changed due to the creaking and MBUX software was updated. I guess the assistance system ECUs were just If updated, because the lane change assistant now works as expected. Panne 2 1 week later again after long distance and charging. Charge errors… got in. Battery malfunction -> Towing prohibited. Errors this time pushed away Car drives normally. 2 days later on a long distance drive. During the ride the following error messages occurred: Battery symbol malfunction -> Drive system disturbed. Disappeared again. Then during the ride several times the error “Without changing the On the MBUX display the message also appeared: “Warning – Mercedes me Connect” – “Mercedes Benz Customer Service Your vehicle has detected a malfunction. Please contact immediately and Mercedes Benz”. Currently the vehicle is back in the workshop. All this has happened in the last 6 weeks. Unfortunately this clouds the impression of the E-Mobili I’ve been having an EQB for a year that we’ve been very happy with and not having any problems with. Did I get a “mountain car” or are the problems normal and have to be solved with several workshop stays? I’ve already read many posts here in the forum, but I don’t feel if these are really general problems or if my car is more of an individual case.
