general problems of the 2003 Infiniti G35

I've recently been having issue with the engine where the car stalls. The car start fine when I do a cold start but when the car warms up the car stalls at times. I've been hearing a lot of the stories from other people on different forums where this is a common issue for this model. The culprit are either the trottle body which I had already replace three years back, the 2 cam position sensors and crank position sensor. I recently found out that there is a recall on the cam position sensors and crank position sensor. I'm hoping that that my VIN# is part of that recall. The second issue I have been having with this car is the radio and temperature control. That I recently had changed with the factory radio attached to the temperature control. The radio would stop working. I have no control over the temperature control and the ac unit would turn on by it self. I recently just installed an after market radio. With everything after buying what was required to do a double din conversion and installation. It cost me a good amount of money. Another issue this car has is the seat belt issue. It doesn't retract properly and the passenger side it's a chore just trying to put on the seat belt.

Infiniti G35 coupe driver seat belt defective. I took it to the dealer in fresno CA in oct. 08. They told me it is fine and a few days later it broke at the anchor bolt. I had to toe it back to the dealer at my expense and they replaced the bolt. In oct. When I took the car to that dealer to check the seat belts they told me that the passenger seat belt in front is defective and needs replaced. When we took it back to replace it they told me it is working fine now and does not need replacement. I am worried that the passenger seat might break just like the driver seat belt did a few days after they gave me a clean chit that it was fine.

Consumer states that both front seat belts are not positioned correctly. Dealer notified.
