2004 INFINITI G35 User Comment / Complaint

I have noticed that the air from the vents is heated no matter what the desired temp setting. i have also noticed that at times i smell fumes coming through the vents even when i am not in traffic. i decided to investigate where the air intake is drawn into the car, and to my surprise, the air is being taken through the battery compartment on the passenger side and the master cylinder compartment on the driver side. i find it unbelievable that the air being fed to the passenger compartment is coming from under the hood - worse from the battery compartment. if you remove the battery cover and look behind the battery, you will see the intake duct and the blower. this has to be a major health issue.
