I hear this too. It sounds like it's coming from the Passenger door. A weird rattle. When I first reported the sound to my dealership, they checked and found a broken clip on one of my front shields, but obviously, that wasn't causing the rattle. I now see this is a common problem. My Patriot is not even 2 years old, barely has 5,000 miles, and I hear noises EVERYWHERE.
Rattle at start-up from passenger side
Drivers seat starting to creak even though I barely drive it
Center armrest starting to creak even though I barely drive it
Squeak/Creak in back (95% resolved with recent stop to dealership)
Poor quality overall. I wasn't expecting the best car in the world for the $25,000 or whatever it was that I paid, but so soon?
