What is the temp when you have this problem. I find that the 300 is the most sensitive to temp changes out of all the Lexus models I sell. Batteries are new and still it has a slow start. My opinion is that it has to do with how the case iron block retains temp, where as, the aluminum blocks do not. Just an opinion I have about this that helps me sleep at night.

Our temp was 42 this morning and my car almost didnt start. Battery in my car is less than a year old. Good Luck

mine happens when i drive the car for awhile and turn off the engine. I think it probably has to do with the fuel,like regulator on the fuel pump or fuel damper on the rail.
