Vibration During Auto Start/Stop In Traffic

[Aisha2721]

I would like some feedback to help me decide if what I am experiencing is normal or if I have an issue. I normally keep my vehicle in ECO mode so whenever I am in traffic or at a light the auto start/stop activates. I think that the vibration or shudder is excessive but maybe it is just me not know how it should react. I thought I read that the Kia has something in the ignition to allow for smoother operation. Something for quick ignition versus a full start or stop? Technically, my description is probably not the best, but should I be feeling a full shudder every time the auto start/stop engages?

Thanks in advance.

I have not felt this on ISG (Idle Stop and Go). But "full shudder" may have different meaning to different people--some may be oversensitive to it. But you have a good question. Let's wait for others to chime in.

There is a noticeable faint shudder/vibration when ISG restarts the engine. But nothing alarming or distracting to me.
