I own a 2012 air bag model that I purchased new and it has 21k miles and is still under factory warranty. While participating in a Patriot Guard escort I noticed a noise coming from the left radiator fan. It sounds as if the bearing is bad or it has leaves or something caught behind the fan & is not visible. I call my dealer's service department and talk to the Manager. He says, "if it is a bad bearing, warranty will cover the repair, but if it is leaves or something in behind the fan, it will be at my expense with no warranty coverage". I'm looking for opinions on this. What is your opinion of the warranty coverage?
