If your dealer is anything like the ones I have dealt with, unless you are bringing it in for a specific complaint, you will get charged for the time to "check things over", in addition to the deductable if any covered components are found to be defective and are replaced. An overall "checkout" would be preventative maintenance, which isn't covered under the warranty.
Some dealers can be a real PITA when it comes to what is covered and what isn't. I used to own a Ram 1500 pickup, which had the transmission crap out under warranty. The trans was rebuilt under the warranty, and ran fine. But about a year after the rebuild, I changed the trans fluid and filter as part of normal maintenance, and found a fair amount of fine debris (clutch i presume), plus a large piece of a broken snapring stuck to the magnet in the pan.
I snapped a few pictures and finished the fluid/filter change. I dropped by the dealer a few days later with the pictures, the receipt from the previous transmission rebuild, and the broken piece out of the pan. Told them what I found, and requested that they give the trans a thorough inspection to find where the piece came from. The service manager said that because the trans was currently operating correctly, they would have to charge me for the transmission teardown/rebuild, but that the cost of the broken snapring would be covered! If the transmission failed within the remaining warranty period, they would cover the complete rebuild.
It held together for about 20,000 miles (now out of warranty, of course), before it started slipping and shifting strangely. Unloaded the truck soon afterward and bought my PT (from a different dealer!).
