Has anyone out there ever got difinitive answer to "Cold start diesel engine problem"
I havnt and have it now on every startup since its cold here now in Ohio.
I have been told its Hi Pressure fuel pump, Fuel injectors, Valve slap, Etc,Etc. but its just normal.
I have had two loaners ES 350's and they were quiet. ???????????????????????
Build date 03/06 and now have 12000 miles. with no other problems. Maybe I'm Lucky................................

Yes,

I was given a firm diagnosis for it on my former ES350, improper valve setting, though repairs offered to address it and expense for doing it were denied by Lexus corporate.

Nice diagnosis by Lexus. My service manager's excuse was fuel injection noise. Funny - the IS250 and RX350 loaners did not have it nor does our new Impala and Grand Cherokee. The local Lexus service department still does not answer the phone, even with four service writers. Goes right into voice mail with maybe a callback the same day or most likely the next day.

It will be interesting to see how Lexus fairs for the 2006/2007 model year reliability and customer service studies going forward.

Is it very few customers complaining, or there a wide spread issue with respect to how issues are handled?

Is it a ticking sound? A lot of GS owners initially complained about the car but it was the direct injection?
Does the ES 350 have it (not sure).

Ticking, and more. it's the sound in my sig.

The loaner cars seem to be quiter. The loaner I have now is my 3rd one, which was built in the same month as mine.

Could it have something to do with the brand of gas you put in?

I'm not too bothered, because the last gen mercedes E430 sounds louder than mine.

I'm thinking after the first oil change, the noise may go away. Our first free oil change is due in March. Have been thinking of switching over to Mobil One synthetic oil as the oil flows freer in cold weather, getting to the valves quicker than regular oil.
