I have a 2006.  The cyclinder change is undetectable and the only way you
know it is happening is the eco light turns on and tells you.  Your car
needs to be fixed but you might want to drive it for a week to see if the
computer figures it out.

Don't wait to hear from others.  The owner's manual is explicit in this.  
You should physically experience nothing.

You're under warranty.  TAKE IT IN.  That's what Honda pays those
mechanics for in a warranty situation.

If they give you the old "they all do that," it's quite simple:  ask to
go for a ride, with the mechanic/service writer, in two or three new
ones they have on the lot.

When those don't do it at all, have the service writer document that and
give you a copy.  Then ask them to FIX IT.

If they don't know how, they have Honda resources to call upon.

Your shiny new $35,000 toy should not be doing this.

I'm glad you read your owner's manual.  Have you read it cover to cover?
