I just purchased a 2009 Genesis 4.6 with 37k miles and love the car, but noticed the steering wheel vibrates while idling in drive. When I shift to neutral the vibration goes away. The rear wheels also vibrate while the car is in motion. I did not purchase the car from a Hyundai dealer, but brought it to the Hyundai dealership near my job who balanced the rear wheels for $80 then told me I should bring the car back to where I bought it 'cause it still vibrates. Not exactly the answer I was expecting and seems I'm on my own to figure this thing out. Anybody have this problem with the steering wheel vibration at idle and if so were you able to get it fixed? The other vibrations while driving seem like they might be related to the driveshaft issue I've been reading about on this forum, but I can't find the TSB for it. Any help is greatly appreciated.
