2008-2012 BMW 1-Series, 2007-2011 3-Series, and 2009-2011 Z4
The Problem: The connectors on both ends of a cable that runs from the positive battery terminal to the fuse block are both coated in tin. That material can apparently fret over time and ultimately break. If this happens, the vehicle can not start – or, if it was already running, will stall.
The Fix: BMW will replace the aforementioned cable with one sporting improved connectors at both ends, and will be secured to the fuse block in a “vibration-safe method.” BMW aims to begin and complete owner notifications in March. For further information, owners can reach BMW through its 1-800-525-7417 hotline, or by emailing CustomerRelations@bmwusa.com.
Number of Vehicles Potentially Affected: BMW’s documentation claims 504,545 cars in the United States are affected by this recall. Approximately 10,020 consist of Z4 models; 44,045 are 1 Series vehicles; and roughly 450,000 vehicles are 3 Series variants. BMW says the percentage of vehicles estimated to actually exhibit the defect is less than 1%, or roughly 5000 cars.
