One month past my warranty expiration date my 350z stalled on the freeway. Subsequent diagnostics discovered a crank position sensor malfunction. The sensor was replaced, and the vehicle ran smoothly for another month or so. I am again experiencing a similar malfunction. Both malfunctions occurred at highway speeds of 60-70 mph. The malfunction resulted in extremely dangerous conditions, as I was forced to coast off the highway. I have read that Nissan has previously recalled vehicles due to this type of malfunction.
