shaking during idle

[BANSwee]

Hey guys. I have a 2011 WRX that up to now only has 300 miles on odometer. I got an episode that during idle (whether on traffic or parking garage) I got this weird feeling that the car shakes-- not too much but you can feel it nonetheless.

RPM is totally normal like 750. I can feel her shake because eveything is off (radio/heater/etc), so no daydreaming/imagining things here.

any guess?

If it's a single episode, you can't fix it -- it now works.

If it's several episodes, take the car in.

If it's routine, it's almost certainly normal. The motor will make the car judder a bit every so often, because of the way it's mounted and how the exhaust is routed. My 02 "shakes" and has done so since new.

+ i like the shake it freaks passengers out.

i like the shake too. would it not also be because of the horizontal pistons? puts a different shake to the car than most inline 4's
