Problems with 2003 Infiniti G35 SEAT BELTS

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 throttle 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 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. *tr

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. *tr

Drivers side seat rocks on braking/turning. i had the car in for an oil change and asked about the seat. the dealer told me they replaced a part in the seat. it helps somewhat but there is still too much play in the drivers seat. it makes you wonder if the seat is actually secured to the car properly, and also in the event of a crash, would the seat hold up appropriately? also the brakes are squealing at 10,000 miles. actually, they've been squealing for the last 4,000 miles. they are starting to make a grinding noise as well sometimes. i haven't been to the dealer about this yet, but it is a concern that the brakes could fail. i previuosly had an expedition and had problems with those brakes as well, but would normally get 20,000 to 25,000 miles out of them.*ak

Consumer states that both front seat belts are not positioned correctly. dealer notified.*ak

I am a 5'2" female and have a new g35 sport coupe. the seat belt sholder strap cuts into my neck do to the fact the starting point of the seat belt is too far back when i adjust my seat forward in order to reach the foot pedals. i have contacted the dealer and the consumer dept. at infinti and they say there is nothing they can do. if i were to be in an accident, this shoulder belt would surley cut into my neck and cause more harm than good. please advise. *ak
