One problem related to brake grinding noise has been reported for the 2003 Infiniti G35. The most recently reported issues are listed below.
Almost 99% of the time when I roll my G35 within 10 mph I hear a crackling or grinding noise (like fan just started) and a "vibration" would transfer from the brake to my foot. Fter troubleshooting (shut down all sound device including ac/fan) and researching the owner's manual, it stated what I described above is normal. It's a self-diagnostic feature on abs system when the car is moving slow. The noise is kinda loud and noticeable. Is it the norm for all abs sytems by other manufacturers??.
