Bought the car as a certified unit at 18K miles. Rattles in the dash and driver's door almost immediately. Loud knocking from injection system (I'm told) when the engine is cold. Parts of the car sound "tinny" when bumped or doors are shut hard. Poor lighting inside and particularly in the rear seat area. Console storage is poor due to unusual access method. The door panels and door sills should be something other than plastic which is easily marked during entry and exit - carpet would be nice - not up to the quality of design I expected from Lexus.
I particularly enjoy the head lights which follow the steering, the key- less features and am very fond (and thankful) for the skid assistance and braking assist systems - both have kept us from serious accidents!! A very comfortable car overall.
Rework the access to the console storage box, install better lighting inside, front and rear. Correct the noises from the engine when cold - very disconcerting!!
