While driving my g37s makes these vibrating sounds near the rear of the car. It's a faint sound from the passenger side but as a driver I can feel and hear the difference. I'm not sure if this has anything to do with it, but a few days ago I ran over this bump that was about 1/4 of a foot high and maybe 2 feet long. I drove around both fast and slow that day and there was no difference. But yesterday driving through traffic I started hearing the noise so I got off the freeway and starte "playing" around with the car to see when it makes the noise. It starts after the car warms up and lasts during the 1st-3rd gear up untill about 4000 rpm.

Any idea's on what this might be? Any input would help, thanks!

 

nevermind, I brought it to the dealership and right when they put it into drive they heard the vibration and knew the problem instantly.
It ended up being a loose tailpipe, they're going to replace it on monday. .
