Hello. When at idle (in park only) I have a noticeable shake. I wouldn’t say it’s horrible.. but it’s present. Also, when traveling down the road, once my truck goes into V4 mode, the truck has a VERY noticeable shake. My truck is still under warranty, it only has 51k so what should I do? Take it to a dealer, or is it something simple like spark plugs? No codes are currently present. Thanks!
