Infiniti G35 owners have reported 3 problems related to gas recirculation valve (egr valve) (under the engine and engine cooling category). The most recently reported issues are listed below.
First defect:
when I would start my car the lights would go out and the radio, heating and cooling buttons. The fan would come onto high and switch to airconditioning. I could not turn it down or turn it off or turn on my defroster when it was 30 degrees in the morning which made my visibility very poor. The only way to get this to stop was to pull the fuses. We check the recall history and found that it was only a courtesy recall and wouldn't be covered even after reading that hundreds of G35 owners were all having the same problem. We had to have the radio electronics removed from the car and sent out to be fixed. I think this issue would be consisted a safety issue when you don't have heat or a defroster. Second defect:
the problem started while the car was idling and it would stall. Then 3 days later while driving at 50mph the car tried to stall and it lost all power and then the dash lights came on indicating service needed. The car seem to lack power. Did a recall check and found that all the conditions pointed to the cam shaft position censor failing. We checked the VIN# and of course my car isn't one that is on their recall list for the same problem they have on other G35 models. This could be a serious safety issue causing an accident when you stall and have no control of your vehicle going down the highway. Every issue I have had with my car has been on the companies recall list but not my VIN # for some reason. This issue to need to reviewed and corrected. Third defect:
we have had to have the motor replaced twice in the drivers door that operates the electric window. Now the right door window is not working. If it does open it will get stuck and we have trouble getting it to come up. We have to keep it locked to avoid it being opened.

I just bought a used 2003 Infiniti G35 a few months ago. I believe I am the fourth owner. It has run immaculate until the last couple weeks. For some reason the air conditioning system takes itself into auto mode and the radio lights go out, along with the rest of the lights on the panel that control the ac functions. I cannot use any of those buttons to change anything. The radio continues to work and I can still use the steering wheel controls to adjust the radio, but I can no longer see the lights that tell what station it's on nor adjust anything from the panel. The ac goes out of manual mode into auto mode, which if I understand it correctly, auto is a normal function, adjusting itself to maintain whatever temperature you have it set at, but the fact that I cannot change it back to manual mode, nor anything else on my own after it goes in that mode, and turns out the panel lights, makes me think this is not right. Thank god it is defaulting to on as it is summertime and over 90 degrees outside, but still gets very cold and is loud at full blast. However, if this were winter months, this would be a safety issue as there would be no way to defrost my windows and obviously cause serious discomfort in having freezing cold air blow on you in the middle of winter. I have seen several other complaints/technical services bulletins about this on mycarstats. Com and wonder if there is already a recall on this. Some folks have stated something about a voluntary recall relating to the circuit board. . . Others have stated a voluntary recall for the equipment relating to this but only included the recall on certain VIN numbers. I haven't yet called the manufacturer, which I will do, but am hoping that this is covered by the manufacturer as in my opinion it is a safety concern and has been complained about by several Infiniti owners.
1 week ago I've noticed a sudden degrade in performance. The car is providing 1/2 as much power as usual, but no warning lights or gauges revealed anything. Inspected obvious things like fuel, oil level and purity. 2 days ago *vehicle for the first time suddenly stalled while driving, and was hard to start again. It took almost 1 minute to restart. Check engine light activated. Car continued to be hard to start after instances that it was shut off. Last night: *vehicle stalled again while driving on the freeway, during my delivery of the vehicle to the dealership to investigate this issue. This is a very dangerous problem, I'm lucky no one crashed into me.
