I noticed this once sitting in the driveway when I first got it home and was setting up my bluetooth... I had the engine running, sitting in PARK. I felt a vibration but thought maybe my daughter had moved or something. But then I was sitting at a Sonic drive-in waiting and felt it again. It comes and goes just as fast as it came. Just a vibration that lasts maybe 2 seconds (if that long). It doesn't happen that often, actually only twice that I've noticed since I bought the truck 2 weeks ago.

Anyone ever noticed this vibration and is it something I should be concerned about? It isn't major, but just enough to notice it. And like I said, it comes then no more than 2 seconds it's smooth again. Now I did have the A/C running the second time, but I don't remember if it was running the first time sitting in the driveway. If I had to guess, the A/C was not on the first time.

AC compressor clutch can cause a slight vibration at idle when kicking on/off. I have a 2013 and have not noticed anything like that, but it's been so damn nice out (finally) have had the heater/AC controls turned off completely.

The engine will NOT go into AFM V4 mode dusring starting, engine idling, and medium to heavy throttle applications.

Thanks f5fstop... I was pretty sure it might be the A/C, but you know, when you buy a new vehicle and you feel a little "shimmy", you ask yourself questions LOL
