if it goes away after one second that is the lack of oil at start up, now if you hear a whining sound which accelerates while reving you need to get the two secondary timing chain tensioners replaced. warranty is 5yr/60,000 and the dealership should have no problem accepting the job as i do it all the time, it can take a day or two to do depending on what time you drop it off.
