The 2003 BMW Z4 has 3 recalls, the most serious being an airbag system processor mismatch that can prevent the airbags from deploying in a crash, leaving the driver and front passenger without that protection.
On the tire side, certain vehicles fitted with 18-inch tires may have sustained damage when the tires were mounted to the rims, which can cause a gradual loss of pressure or sudden tire failure while driving. There is also a fuel system concern where the electric fuel pump can vapor lock under hot conditions at altitudes above 5,000 feet, stalling the engine and making it unable to restart for up to 20 minutes.
