The 2009 BMW Z4 has 3 recalls, the most serious being a PCV valve heater that can short circuit, melt surrounding components, and start a fire whether the car is running or parked.
The fire risk applies even when the vehicle has been shut off and left unattended, making it a concern beyond just driving situations. The third recall affects a narrow production window of vehicles built in mid-March 2009: a faulty crimp connector in the seatbelt tensioner wiring can develop high electrical resistance, causing the tensioner to fail to tighten the belt in a crash and leaving the occupant with less protection than the restraint system is designed to provide.
