my rx 350 also sounds like a cummins diesel when started cold you see i bought this car used for my wife in the hot summer so this noise was not there at that time ,but when the weather began to get cooler also reered its ugly head . i had before this car a top of the line toyota with the 3.3 litre engine that in my opinion is so much superior to this new 3.5 litre . it was so queit you couldnt even hear it running , this how ever i am very disappounted in sounds dreedful for an expensive luxury suv .
