Nissan has determined that some 2003 - 2004 model year Nissan 350Z vehicles may have a defect which relates to motor vehicle safety. There is the possibility that the fuel filler hose may crack and result in fuel leakage from the hose while refueling. If an ignition source is present, a fire could occur. In addition, fuel vapor hoses may crack and cause the malfunction indicator lamp to come on. To prevent this condition from occurring, Nissan is conducting a Voluntary Safety Recall Campaign to replace the fuel filler and vapor hoses with new ones.
