Is the BMW eDrive de 5.ª generación (iX3, i4, iX) reliable?

The sources consulted record no faults with the motor or the reduction gear. What is documented are small recalls for the battery (cells, modules, pads) and the integrated charger, concentrated on cars built from 2021 to 2023: ask for the chassis number and the paperwork.[1][2][3]
