I did have a scary engine shaking on the very code weather day when start and the engine kick on. MY wife so scare to take the trip on that day. It was noisy and shake drastically. Also, when driving on the local street and start to slow down for traffic light we heard the buzzing sound coming from left side of the car twice then stop. Buzzzz , Buzzz. I thought it only me but my wife who sat on the passenger side was mention it too. Is anyone having the same problem I have? The RX350 is a lot more quiet and smoother ride...

This morning I experienced a somewhat similar problem. We've have some cold weather (plus a big snowfall) and when I took my 2012 CT on the highway this morning it would shake over ~65mph. It wasn't purely related to acceleration and even after 45min of driving it did not really improve. Anyone else experiencing this?

^snow or ice on the wheels or on the inside of the barrels. Causing an imbalance. Very common with snowfall

I have a 2012, and on four occasions, my car has rumbled loudly upon starting. I turned it off and restarted without a problem. I took it to dealer today. Needs a new intake manifold. I asked how they would know it needed the new part; I was told it was based on serial number. They redesigned the intake manifold. Before the redesign (2011 & 2012, I believe), you may have the extreme shaking & rumbling when starting...
