I went to the dealer and found out that the wheel bearings are causing the car to vibrate, and the service manager said that it is a part that fails often so he would replace it under warranty. Hopefully this cures the problem and no more vibrations.
on a side note I know how you feel because I havent driven my G for about 1.5 months and then last week I finally made an appointment because I miss driving my G. If this remedies the problem you will be the first to know unless you get them changes before me

 

Are you getting any noises at all? Or only vibrations?

 

Anton I have an update for you. Infiniti changed out my rear wheel bearing and all the noise/vibration that I had went away, I drove the car about 80 miles and didnt get any vibrations from the car it felt like it was brand new. I would have tested it more but as soon as I brought it back to Infiniti I traded it in for a new car. Its a 2011 Vibrant Red G37S 6MT and im picking it up tomorrow. I thought I'd let you know that this may be a solution to your vibration problem.

 

did your vibs come and go..or no..and at what speed did it start..was it in the wheels


see you had noise..i really don't have any

 

to tell you the truth I told the dealer that I was getting noise because that was the only way to change out the bearing. the vibrations in my car started at around 55 and stayed until 90. it would go on and off sometimes but thats if I break hard and accelerate hard again

 

because i am still getting 40-60 deg higher temps on right front..nissan said don't worry..but why is it like this is why i want to know
