We live in northern Michigan, so rust is definitely something we all see. But my fiances 2010 Avenger, is only 4 years old, and the rust is coming from under the paint. I would understand if the paint had been chipped and everything underneath was exposed, but that was not the case. The 5 year/100,000 mile warranty says it covers rust, but when we took it to the dealership they said it only covered it if it was "rusted through." We are very disappointed, and I am going to add pictures of the bubbles soon. I hope there is an easy fix, like buffing it out... and suggestions would be appreciated. thanks!
