BMW of North Americais recalling more than 4000 model year 2025 330i, 330i xDrive, 530i, 530i xDrive, 4 Series Coupe (430i, 430i xDrive), 4 Series Convertible (430i, 430i xDrive), 4 Series Gran Coupe (430i, 430i xDrive) and X3 30 xDrive vehicles. The electrical connection between the Chinese-made starter-generator and battery may come loose. The supplier is Shanghai Valeo Auto-Elec System Company.

“This safety recall involves the power connector component of the starter- generator which may not have been produced by the supplier according to specifications. During the supplier production process, a gap could form at the connector location. If a gap exists, this could cause a loose connection between the connector and the positive battery cable (or wiring harness). As a result, resistive heating could start to occur,” BMW said in the required safety defect recall filing made public this morning by the National Highway Traffic Safety Administration.

“This could result in a loss of charging function, and engine stalling without warning, which could increase the risk of a crash. Also, over time, overheating could increase the risk of smoldering and, in an extreme case, a fire. Both of these conditions could also increase the risk of injury,” BMW said.
