Brief knocking during cold start on 2008 Scion xD

Hello Scion owners 2008 Scion XD 67,000 miles Has anyone had this problem and had to replace the timing chain? Did the problem still exist after the chain replacement? My Toyota dealer said it will cost $600 to replace and there's no guarantee that the problem will go away. They state that the timing chain skips for the brief second during starting, but won't effect the engine performance, nor would it do any damage. The 5 year/60K mile warranty just expired and they declined doing a "Good Will" service. Any info will help.

Some engines may experience a brief knocking or rattle on cold start up. Our technicians tell us replacing the camshaft timing gear assembly with upgraded parts will generally correct this concern.
