P1404 is an EGR valve getting hung up. I'll ask, is this on the 3.8 engine with 50-70K miles on it? If so they seem to be prone to EGR issues, a new EGR valve is pretty easy to install. Also being just 1 month out you could perhaps visit the dealer and ask for a good grace period on the warranty---ASK BEFORE they even touch your car, if not you'll be paying for the diagnostics.
