Hi I just purchased a used 2017 DGC SXT 35,000 miles on it. When starting the engine cold it has a low moan or drone noise coming from the engine pan area. The noise gets louder as the Idle slows to normal idle then after 10 minutes as it warms up the noise is gone. It will only return when the van has been sitting overnight and the engine is cold. I have it now at a dealer over the weekend so on Monday they can start it cold and hopefully hear the noise and diagnose before the warranty runs out. I never heard a noise this loud on any other van I have owned it really resonates in my garage. Any Ideas from owners or tech's would be much appreciated I've been searching the web in hope of finding a cure but as of yet have not. As one owner stated Dodge has no solution I'm thinking this will only get worse as the temperature drops here in Central Wisconsin.
Thanks Mike W
