Model: G37X
Make: infiniti
Year: 2011
engine/transmission option: 7spd auto 3.7l v6
are you mechanically inclined/have the right tools?: youtube warrior

Issue(s):

Hey guys I have a 2011 Infiniti g37x with 97k miles. I put brand new tires on it 1k miles ago and have had vibration issues since that I can feel in my steering wheel, gas pedal, and seat when I go over 70 mph. I have had my tires balanced twice, an alignment done and have had the tires and rims checked with no concerns. The vibration is driving me bonkers and Im curious of what else I can check that makes sense. Car is smooth as glass till I get on the highway and other than a cat-back and intake it's stock.

Thanks all

Does it vibrate while gas is applied over 70 or does it vibrate over 70 under any circumstance. Feel like its coming from the suspension or something else is causing it?

Happens with and without gas. Every so often itll subside only to come back a few seconds later.

Same tire size as oem?
When have u last changed rotors. Could be warped. But u said with and without gas.so cant be that. Could be a bad or out of balance driveshaft too. You can always try a road forced balance. They can probably find out whats going on.

Easy way to rule out two common possibilities is lift the vehicle and try to shake the wheels to see if it’s a ball joint/bearing issue or it could also be the lug nuts aren’t even torqued.
