general problems of the 2002 Infiniti I35

I have had two transmissions in this 2002 Infiniti I35 and now may have to have the third. Summer of 2011 I experienced intermittent issues with the engine racing and the transmission apparently disengaging, with no power to the wheels. First time I took it to the dealer they couldn't detect any problems as there was no service engine soon warning on the dash board so their computer couldn't detect a problem. Happened again and the technician told me not to turn the ignition off when I got to the shop but to let the engine keep running. He drove the car back to the shop and hooked it up to the computer. The problem was diagnosed as the torque converter clutch function code along with p0720 and p1574, check engine light concer – ip006, (failing), and I was told I had to have both a torque converter and a transmission. The price for a new one was too high and I opted for a used torque converter/transmission and now, 5/2/2012, less than a year later I am having the same problem as before. Several times this loss of power to the wheels has happened when pulling into traffic and is extremely dangerous. Another issue is the suspension and steering. I have had to replace the struts because the front end would vibrate veer left and right and lose some control over the steering when driving over rough pavement. Even after strut replacement the issue still persists. August of 2011 around the same time transmission was replaced I had to replace the radiator which burst at a seam. It was replaced before the transmission and at a different shop, and not at the dealer's shop.

This vehicle dangerously pulls to one side or the other when pressing the gas pedal, especially during rain or on turns where consumer loses control.

The vehicle experienced the following:the engine shaked, and was noisy, front end shaked and pulled, the door locked by itself when it was slammed, the acceleration pedal did nothing when driven in high speeds, the clock knob was inoperative, front dash had electrical problems, gas mileage was abnormal, cd player was inoperative, and there was a rattle noise inside of the vehicle. The consumer had loss control of the vehicle due to the front end problems, there was excessive play, when going over bumps, the dealer stated the vehicle was normal. Scc.
