I hope you are right.  My '07 base has a slight ticking at idle, when cold.  It seems to go away when the engine is warm and run above idle.  The dealer says it is normal for this engine.  I choose to believe him for now.  We'll see what develops, if anything.

Your dealer is right.  Our engines tick slightly and it's nothing to be alarmed about.
