2008 Lexus IS250 RWD. 118K miles

This occurs probably 50% of the time when I turn on the car. It makes a sound similar to "baseball cards on spoke of bicycle" when I turn on my car. No other issues. It drives fine but just concerned it might be a bigger issue. Like something is rubbing against something else. Goes on for 1-2 seconds. Sometimes no noise at all.

Probably a CV joint. Check the boots and see if they're leaking at all.

Figured it out, its the car rattle issue (cam gears). Apparently not a big deal, just a nuisance?
