I bought my car which is E200 2020 mild hybrid last year as a second hand car but it had a maintenance contract with the dealership for a year. After a week of buying it I had this msg the 48 battery in yellow followed by park your car and call dealership in red. The msg appeared immediately after I've started my car but after switching it off and on it disappeared and did not even keep a record of it. After a year and exactly last week I also had this msg after driving for 5 minutes but also disappeared upon turning the car off and on again. In these two times the car was working normally. I sent my car today to the dealership for the yearly maintenance and told them about this issue. They are keeping my car for the time being and they told me it might be need a software update. Reading this thread makes me very worried. Changing the 48 volt battery won't be under warranty and it is expensive. Please give me your thoughts on this. Thanks
