One problem related to service engine light on has been reported for the 2007 Infiniti G35. The most recently reported issues are listed below.
While driving, my Infiniti g-35 looses engine power and the engine shuts off while driving without notice along with sudden lack of power steering. My service engine light stayed on when I started the vehicle back a short time later. Several cars had to swerve from hitting me. I was able to make it to get a diagnostics and it's saying crankshaft position sensor/ camshaft position sensor. The engine shutting off while driving start happening other times same way. This happened on the expressway and main roads. This could have caused a major accident. My airbag light is also flashing red and highlighted passenger airbag light off in yellow near clock. Engine shutting off due to crankshaft sensor with airbag malfunction. Engine also shuts off at stop lights.
