I m using Forte 2.0
When I drive my car more than 110km/hour,  I can hear sound like wind blowing,  from passenger side. I sent to SC, but cent detect the problem. Anyone has similar issue and know how to solve it?
Regarding the rattling sound from dashboard,  can it be solved?  My SC said they do not received any solution for it yet from Kia, so they do not dare to repair it as afraid it will cost more problem.  But my fren at Ipoh SC can service it by installing something. So is there a way to solve this issue?

I did encountered same problem also on 1.6SX. Donno what went wrong.

But now it gone... Dont know what has helped. I tried Ron97, different petrol Caltex / BHP Ron95, Sent for service last month, Installed FireStorm.

Now no more or very little vibrate only.

2.0sx uses EPS for the steering, which is driven by electric motor. not too sure the vibration in your context, but i guess is the very very minor "clicks feel" which resulting from the electric motor that the engineer calls it cogging torque.

1.6sx/ex that uses hydraulic type power steering would rather feel engine vibration (but could be negligible too) when turning the steering wheel because this power steering pump is belt driven by the engine.
