2004 Sonata with excess vibration in steering wheel

My first thought is a loose or leaking vacuum hose, but surely if the dealers tech has checked it out they would have found that.

Sonatas with the 2.4 engine have quite a lot of vibration when the car is in gear. This is, unfortunately, inherent in their design and will never go away.

Since you say the vibration has gotten worse since about 27,000 miles, it's possible that you have an issue with the motor mounts. If that's the case, replacing them will reduce (but not eliminate) the vibration.

You could call Hyundai customer assistance, but I'm thinking that won't get you very far unless you meet with the factory rep and are absolutely adamant that the vibration is significantly worse than before.

If you're game, call the service manager and offer that you won't bring the issue up again if they replace both upper mounts (one engine mount onthe right side of the vehicle, and one transmission mount on the left). Of course, this means that if nothing changes, you'll need to keep your word that you won't bring it up again. But in that case, I'm suspecting that the vibration is indeed normal, as they say.

I was told today by the dealership service manager that in was inherent with the 2.4L engine and that there was nothing more they could do. I have called the Consumer Affairs to complain about it. They are to call the dealership and get back to me next week. I will ask about the motor mounts. Thanks.

Is there a torque spec on the motor mounts? I wonder if that is my brand new vibration problem. (I just had the motor mount out to work on the timing belt. - 01 sonata

Every bolt in an automobile has a torque spec. You should be able to find it at
