BMW i3 drivetrain malfunction and battery loss preventing vehicle from starting on BMW i3

Some BMW i3 owners report experiencing drivetrain malfunctions that prevent the vehicle from starting, often indicated by warnings such as "Drivetrain: Stop carefully," which can render the car immobile. These issues may be linked to battery concerns, including a dead 12V battery caused by loose terminals or problems with the DC-DC converter, prompting owners to regularly check the battery, especially if it is older. Additionally, some owners find that regular maintenance, such as changing the differential fluid every 20,000 to 50,000 miles, is crucial for preventing drivetrain issues. Diagnostic tools like BimmerLink are also mentioned by some owners as helpful for identifying and clearing diagnostic trouble codes (DTCs) that may impact drivability. Furthermore, staying informed about recalls related to the BMW i3 is essential for addressing potential drivetrain malfunctions promptly.
