What can fail
Some vehicles have high-voltage battery cell modules that may not have been made correctly. These faulty modules could fail, causing the high-voltage system to shut down, which could result in loss of power to the wheels or battery overheating.
What the fix does
BMW will mail you instructions to bring your vehicle to a dealership, where technicians will replace the affected high-voltage battery cell modules.
