I noticed minor vibration up through the steering wheel while idling in drive this morning. Don't recall noticing this before.
Any common causes for this, or what's supposed to insulate the steering wheel from engine vibe?

It is an AWD thing apparently. Mine has been doing that since new. Occassionally, while idling at the lights, it comes on for a few seconds and then goes away. Have it investigated by a dealer and they could not fault it (does not mean there isn't a fault). They just said it must be a characteristic of the AWDs.

Well, it's not a strong vibe, just minor. I only just noticed it though, which is a bit weird.

Yes, it is not very strong. Just a throbbing type feeling like wup wup wup wup wup..... at about 3-5Hz.

Well i've been monitoring this and it comes and goes. Sometimes it will be there after i pull up and other times theres hardly any vibe at all. Just seems to be random. Its not a strong vibe, but for comparison my KH never does this; it just has always had a constant slight vibe at idle.
(Although the KH has always had a slight hunt in the idle, occasionally dipping slightly if u watch the needle, especially after idling for a few minutes, which the KL doesn't seem to have).
