Re: Droning/vibration around 58 MPH w/ V6 in highest gear
There's been multiple threads on this issue, and I've reported it myself to Chrysler. I think that the consensus is that it's happening at high gear under light load, its not something that is causing any damage, and its only a minor annoyance for a small period of time in an otherwise silky-smooth engine.
Personally I suspect that it has something to do with the VVT system and can probably be fixed by tweaking the computer that controls it. Hopefully the factory will figure it out and issue a TSB.
