I've noticed lately when I first start my car with the AC on, my car has a low pulse vibration. I Rev the engine a little and it goes away. After the car warms up ebough I really don't get it..my car is a 2011 with 46xxx miles only. Every once in a while I notice I get a bit of a vibration while sitting at a stop light. AC not even on either. Anyone else have a similar experience?

Yep, I am experiencing this also.
I just changed my valve cover gaskets and new serpentine belt. Have 151k miles.
Not sure if changing those things, obviously had to take things apart, do not sure if that had to do with it but yeah, steering wheel/car vibrates a little with a.c. On sometimes and sometimes without while idle.
If it vibrates with a.c. On, if I turn the a.c. off, the vibration stops.
Maybe just the engine age? But weird I only noticing it after I took apart the stuff to do the valve covers.

Yeah that's pretty muc exactly what I'm experiecing. I've never had my valve cover off so that couldn't be the culprit. Same as you when I turn the AC off the vibration stops. But sometimes I'll come to a stop at a stop light, even with the AC off and feel a low pulse vibration. We know our cars, I know it's there. Very slight but annoys me because it didn't used to be there.
