The 2007 BMW Z4 has 2 recalls, both centered on the same fire risk: the positive crankcase ventilation valve heater can short circuit, overheat, and melt surrounding components, raising the risk of a fire even when the vehicle is parked.
The risk is present both while driving and shortly after the engine is shut off, meaning the vehicle does not need to be running for a fire to start.
