The 2007 BMW 3 Series has 4 recalls, the two most serious being a fire risk from an overheating PCV valve heater on N52 6-cylinder engines, and a battery cable connection that can fail and cut power to the entire electrical system while driving.
The PCV valve heater can short circuit, causing surrounding plastic components to melt and potentially catch fire, both while driving and shortly after parking. The battery cable issue can cause the engine to stall and knock out lights and other electrical systems without warning. Prior repair attempts did not fully resolve the battery cable issue, which is why it appears more than once in the recall record.
