I have a 2007 350Z that I bought new (currently somewhat over 30k miles, 6 speed manual coupe)which I drive daily to and from work. Sometimes when I am in 1st gear and release the clutch while still somewhat on the throttle, I hear a clanking noise. This often happens when I am leaving the underground parking garage at work (going up a moderate incline). I have reported this to my dealership each time I have had my oil changed (they suckered me into an oil change plan; I change my own on my other cars). They say that the clutch is operating normally and they hear nothing. I have checked underneath car and nothing is loose. Has anyone had similar clutch problem.? ---

A weak motor mount is the first thing that comes to mind. Torque the engine up while holding the brake to see if the engine rocks. ---

Does this happen every time you drive the car, or only the first time you drive the car after it has been shut off for a while? If its the latter, then it is most likely the ABS system’s self test that occurs at 10 mph. You can read about this in your owners manual. Section 5 Page 22. I’ll post it below. BC. * * * Self-test feature The ABS includes electronic sensors, electric pumps, hydraulic solenoids and a computer. The computer has a built-in diagnostic feature that tests the system each time you start the engine and move the vehicle at a low speed in forward or reverse. When the self-test occurs, you may hear a ?clunk? noise and/or feel a pulsation in the brake pedal. This is normal and does not indicate a malfunction. If the computer senses a malfunction, it switches the ABS off and illuminates the ABS warning light on the instrument panel. The brake system then operates normally, but without anti-lock assistance. If the ABS warning light illuminates during the self-test or while driving, have the vehicle checked by a NISSAN dealer. Normal operation The ABS operates at speeds above 3 to 6 MPH (5 to 10 km/h). The speed varies according to road conditions. When the ABS senses that one or more wheels are close to locking up, the actuator rapidly applies and releases hydraulic pressure. This action is similar to pumping the brakes very quickly. You may feel a pulsation in the brake pedal and hear a noise from under the hood or feel a vibration from the actuator when it is operating. This is normal and indicates that the ABS is operating properly. However, the pulsation may indicate that road conditions are hazardous and extra care is required while driving.
