My Mercedes suddenly shut down on the M25 motorway on September 14th, 2024, displaying a “48V Battery Malfunction” error. This unexpected power loss put me and other drivers in danger. I managed to coast to the emergency lane, but the situation was incredibly stressful and dangerous. This incident repeated four times that same day.
I tried contacting Mercedes Assistance using the in-car button, but my attempts were unsuccessful. After waiting, I was able to restart the car, only for it to lose power again shortly after. This forced another emergency stop. Finally, after about 15 minutes, I managed to restart the car and drive home.
This experience has left me deeply concerned about the car’s reliability and safety. I emailed Mercedes support hoping for a solution, but I haven’t received a response yet. I chose a Mercedes over a Range Rover believing it would be more dependable. This incident has proven otherwise.
Has anyone else experienced a 48V battery malfunction in their Mercedes? What solutions did Mercedes offer? Is this issue covered under warranty? My primary concern is understanding the cause of these repeated failures and ensuring the vehicle is safe to operate. The lack of response from Mercedes support is further amplifying my concerns regarding the 48V battery system in my vehicle. A reliable 48V battery is crucial for various functions in modern Mercedes vehicles, and its malfunction can lead to significant safety hazards.
