The radio one day stopped getting good reception. I checked all the connections on the back and the antenna. I noticed later that If you are parked with no engine running it works great but when it is running no such luck. Please help.

That sounds like you're getting interference from the ignition system but it sounds too new to that type of issue.
Have you asked your local Dodge dealer if this is a common concern? There may be a simple software update to address this.
