One problem related to wiring has been reported for the 2007 Infiniti FX35. The most recently reported issues are listed below.
I was driving and the car began to lose power and seemed to idle rough and the service engine light turned on. When I was able to pull over the car was on fire near the catalytic converter. The dealership said they had to replace the electrical coil and wiring before hey could determine any further damage. My vehicle is the awd 2007 Fx35 with only 69750 miles.
