One problem related to car will not start has been reported for the 2002 Infiniti G35. The most recently reported issues are listed below.
I have a G35 2003 and had to replace the radio 28041-am883 circuit board on 5/10/07 (it was under warranty at that time). Also, when I was traveling up north the car would not start last winter I took it to a independent repair shop and they disconnected the radio - charge the battery - and it works fine now. Today 06/30/09 I am having exactly the same problem as I did in 2007 - the air is running a full blast and I have no control over it or my radio. Something needs to be done and Infiniti is will aware of the problem as are all the dealership!! all they are doing is raking in more money for a defective part - I believe there should be a recall on this circuit and Infiniti should be fined!!.
