What Happened
The starter assembly is the part that gets your engine going when you turn the key. In your 2025 3 Series or 4 Series BMW, the electrical connection between the starter and the battery might not be secure.
Risk if Unfixed
If this connection comes loose, your engine could stall, making it hard to control your vehicle. This could lead to a crash. Additionally, the wiring might overheat, potentially causing a fire.
Free Fix
Your BMW dealer will inspect the starter-generator and battery cable, and replace them if needed – all at no cost to you. They'll let you know when the fix is available and schedule the repair.
