The automaker said that internal inspections revealed that welding beads on the high-voltage storage tank were not completely removed during production. It said that in rare cases, depending on the shape, size and position of the welding bead, a contamination during the initial charging process could cause a malfunction, such as a short circuit in the high-voltage memory.
The company confirmed the defect to the German publication, and said owners of the affected vehicles are currently being individually informed. In the meantime, owners of the affected vehicles have been told to not charge their cars at a wallbox or charging station until the cars have been checked.
It told the magazine that technical action would begin shortly and will involve checking the high-voltage storage for vehicles already in customer hands with regard to the charging history, and if necessary, further measures will be taken. Meanwhile, the country’s Federal Motor Transport Authority (KBA) has also been informed of the problem and is planning to release an official recall soon.
