In the fall, 2010, my BMW 2004 Z4 stopped automatically opening and closing the convertible top. According to the mechanic there is a known problem with the motor associated with it. The main motor gets water trapped inside the plastic housing whcih causes the motor to fail. I need to replace the motor, as many other owners have. BMW knows of this problem and should do a recall/replacement with it's updated plastice housing of the motor. It will cost approximately $3000 to fix it. It is a known defect.
26sep12 the tire pressure monitoring system will provide a false failure when there is certain electrical interference (e. G. Cell towers). This is a recognized fact as noted in the driver's manual (p. 71). The issue is that the system fails to reset after the interference has passed and all of the failure lights remain on for an indeterminate period of time (from 2 hours to 3 days) before automatically resetting. Absent this resetting the car is unsafe as, without a warning system for tire failure (either low pressure or tread failure), an accident could occur. The dealer offered no solution as the computer does not register a system incident and all systems passed a computer check on 16aug. . BMW north America (scott kuchta, 201. 263. 8268) could not provide any further assistance. A properly functioning reset system is needed to insure safe operation of the motor vehicle.
