BMW Starter-Generator Problems Cause Recall

Posted in Recalls

— BMW has recalled about 4,600 vehicles because they could stall without warning or possibly experience electrical fires.

The recall includes these 2025 models:

  • 2025 BMW 330i
  • 2025 BMW 330i xDrive
  • 2025 BMW 530i
  • 2025 BMW 530i xDrive
  • 2025 BMW 4 Series Coupe (430i, 430i xDrive)
  • 2025 BMW 4 Series Convertible (430i, 430i xDrive)
  • 2025 BMW 4 Series Gran Coupe (430i, 430i xDrive)
  • 2025 BMW X3 30 xDrive

According to BMW, the electrical connection between the starter-generator and battery may come loose and cause the vehicle to stall. A fire is possible if the wiring overheats.

A supplier apparently caused the problem by making mistakes when building the power connector components of the starter-generators. BMW found a gap could form at the connector location and cause a loose connection between the connector and the positive battery cable or wiring harness.

BMW received a dealer report from a dealer outside the U.S. in December 2024 where the vehicle wouldn't start and there was a burning odor in the engine compartment. It was determined there was local smoldering at the connection between the positive battery cable and the starter-generator.

BMW opened an investigation and more reports arrived from the field.

The automaker found there were several starter-generator suppliers, but the problems occurred to starter-generators manufactured by one supplier.

BMW recall letters will be mailed May 23, 2025. Dealers will possibly replace the starter-generators and positive battery cables.
