We have noticed a foul smell coming from the air vents every time we start the vehicle. It lasts for about 30 seconds and then goes away. Started around 5000 miles. The dealer said to turn off the a/c and let the fan run for a few minutes to dry out the moisture. I live in Las Vegas, it is dry here and I've owned multiple vehicles in my life and NEVER have I ever had this problem. We returned to the dealer, they said they would blow out the lines and wanted to charge us nearly $200, since it was unscheduled maintenance. We argued and they "said" they fixed it. Next day, the smell returned and now it blows the nasty smell randomly while driving. It is once again at the dealer and they said it may need a new "Purge Module" and they will get back to us with a cost. That is absurd! It's brand new! How can they justify charging anything? Is it the dealer, or is it FORD policy? Very unhappy customer!
