Help! G35 making strange noise

[queenofkings]

Maybe someone here can help me. The first time I hit 5 mph after starting my car, I hear a kind of 'swoosh' sound. It won't do it again, until I turn the car off, let it sit for a while, turn it on again, and hit 5 mph. What could this be? I hope nothing serious as I just purchased this car used. Any comments would be greatly appreciated. Thank You!!

What did the written report of the INDEPENDENT Infiniti certified technican say..............always a good idea to contract and pay for a complete inspection and evaluation.

So many G35 are being [trashed abused exercised] and modified by young adults, you must be very careful on buying used.

ABS Self Test? Haven't noticed it in my G, but it's not my daily driver...
