Component
ELECTRICAL SYSTEM:12V/24V/48V BATTERY
Manufacturer
BMW of North America, LLC
What Happened
The 48-Volt battery in your vehicle helps power extra features like your engine assistant. In some 2021 models, the connection to the starter-generator might not be secure.
Risk if Unfixed
If the connection isn't secure, it could cause a fire, especially if the electrical resistance gets too high. This could put your vehicle and everyone inside at risk.
Free Fix
Your BMW dealer will check the connection between the 48-Volt battery and the starter-generator. If it's not secure, they'll replace it with a new one, free of charge, and you should schedule the repair when you get the recall notice.
