Tried to take the xb to the toyota dealer to figure out what's the rattle sound coming from the xb and they told me I could be looking at a "diagnostic fee" to see what the problem is. I thought the 36,000 miles coverage covered things like this. Its not like I'm taking it in for service. Am I wrong?

I fhtey identify a problem that's covered by warranty, then there should be no charge. On the other hand, if they either can't find a problem or if the problem isn't covered by warranty, then there will be a charge. The technician's time is money and they don't give that away for free.

if its rattling when your at a stop an idling, twist the hood bumpers in the engine up a bit, this will resolve it.

The rattle seems to be only when I press on the gas pedal. Never when I'm just cruising or when I break or even when I idle. I've been told to up my octane and give it a few days. I just thought I should take it to a dealer just in case its something else.

Try adjusting the hood bumps like the other poster suggested. Maybe the car is twisting with the torque of the engine when giving it gas. This is a easy thing to try, start with a half turn (counterclock wise), if you turn too much they will just come off and you can just screw them back in. Just did this again to stop my hood noise, not much adjustment left, might have to glue some small piece of rubber on top to make them taller.
