What's up CL, I'm fairly new to this whole posting on forums and all but i do need some input.
I bought a 2010 is250 back in December. I am now at 65k miles and I've recently (about a month ago) started noticing that my car starts to tremble after a while of being on idle. It's not anything super noticeable but if I really focus on it, I can feel a mild shaking inside the cabin after a while. Have any of you experienced this? Any ideas of what could be causing it?

Motor mounts maybe? Check for leaks on the motor mount points. May just need to be replaced..

carbon build up is a big issue on early is250 models due to the engine design, not sure if they updated the pistons and such by 2010 (pretty sure they did) maybe someone else can verify that

if not carbon build up i would also suggest motor mounts next.
where in CA are you? im have a transmission problem and contacted Alexander F at L-Spec and he said he would diagnose it for free. maybe he will do the same for your problem
