So I've been driving my new Lexus for about a month now and have no complaints - love it. But for the past week I've paid close attention to the feel of the engine at push button start up - it shakes a bit. After it's started and I'm driving , no problems. But it shakes a little when I turn it off, but it stops right after that.
Now, prior to this purchase I drove an Acura MDX and this never happened. But of course that was a heavier, larger, sitting higher vehicle so it's possible those factors are the reason it never happened with the MDX.
But I am wondering if this is normal for the Lexus 350?
Should the engine shake a little for this size vehicle?
